17.4.2 Access point centric Test Profiles
Access point centric test profile means that all individual active tests are run against an access
point at once. After all active tests of the profile are run against the access point, the profile
proceeds to test against the next access point. Access point centric profile can be configured
so that all active tests are run within a single association with the access point. This helps
reducing workload of authentication servers.
If the test profile introduced in the previous chapter would be access point centric, the
execution order of the tests would be the following:

As it can be seen, now the execution order of the tests differs from the execution order of test
centric profile. All active tests are run in a row for each access point.
If the profile is configured to remain associated between tests, the monitoring station does not
detach from the access point after a test but remains associated until the test profile proceeds
to a next access point or a passive test.

17.10 On test elements
Each test has default parameters, which can be used as is or modified as needed. To obtain the
best results and find the best measurement methods for a target network, plan and configure
the tests to suit the network.
A test profile must be configured for each monitoring station separately. The same profile can
be used in several monitoring stations.
17.10.1 Modifying test parameter and test name
If you wish to modify individual tests, see the instructions below. For each test, do the
following:
1. Select the test from the profile and right-click the test
2. Select “Edit”
3. If desired, change test name (for example, for distinguishing Ethernet tests)
4. If desired, set the test duration (in seconds)
a. The test duration does not affect the running of the test; however, if the test
type is temporarily removed from the test set, the time specified is spent in
sleep mode, depending on the configuration
5. For some tests you may also do the following:
a. Select the interval, or the pause between pings
b. Select Sonar
c. Select SIP server (if SIP register test is configured)
d. Select an access point

6. Select “Keep changes”
7. Select “Save all changes”
17.10.2 Disabling and enabling test elements
A test element within test profile can be disabled. This means that the test is excluded from
the test profile and the test won’t be run until it is enabled again. Disabled and enabled test
profile elements can be identified by their colors (see beginning of the chapter 17).
How to disable a test element:
1. Select the test element from the profile and right-click
2. Select “Disable element”
How to enable a test element:
1. Select the test element from the profile and right-click
2. Select “Enable element”
17.10.3 Use case: Multiple SSID testing
There are two ways to achieve testing on multiple networks on one single monitoring station.
The first is based on element copying (the previous paragraph) and the other is using copies of
essid objects.
Using copies of elements may be burdensome at the configuration time but gives control over
the test order. By copying one single element (test type) to be sequentially tested on different
WLANs produces the following sample profile:
1. TCP on Wlan1
2. TCP on Wlan2
3. TCP on Wlan3
4. Spectrum
5. MOS on Wlan1
6. MOS on Wlan2
7. MOS on Wlan3
8. Scan
The other approach is the create a simple test sequence as essid and then duplicate the essid
object and make the duplicates to point to different WLANs. The resulting sample test profile
would be similar to the following:
1. TCP on Wlan1
2. MOS on Wlan1
3. Spectrum
4. TCP on Wlan2
5. MOS on Wlan2
6. Scan
7. TCP on Wlan3
8. MOS on Wlan3

7signal Sapphire Carat User Guide Release 5.0
Please observe that in the latter approach the measurements on a single WLAN network shall
be sparser temporally. While individual tests shall happen on roughly the same time interval,
the distribution of the samples per network differs a great deal on these two approaches.
When planning the test cycles, one should bear in mind:
• The more tests there are in the sequence, the bigger the difference in sample
distribution.
• The more networks, the fewer samples for individual networks.
17.11 Running Test Profiles
Select “Tools | Automated tests management” to see current status of Eye units.
Figure 35: Automated tests management view
The Eyes of the user context are enlisted in the box on the right. The Eye name, the test profile
name and the state of the test profile run are indicated.

19 SERVICE LEVEL AGREEMENT
Service Level Agreement (SLA) groups a number of KPIs and their expected target values. In a
nutshell, typically a KPI has a scalar value while SLA is combination of numerous KPI values and
statistical rules that result in a higher-level view on the quality of the network.
The ultimate goal is to bind together a contractual agreement and actual measurements, the
expression of the desired or required level of the service and the proven real-life phenomena.
As such, the SLA is a communication medium between the service provider and the customer.
The SLA outcome is percentage value and based on user-defined thresholds it is divided into
values green, yellow and red according the three-basket principle. This means that the end-
user experience on the WLAN network might remain adequate but the resulting SLA value is
clearly in the red basket.

SLA group KPI definition
19.1 Defining a Service Level Agreement into the system
A network service provider can make Service Level Agreements (SLA) with their customers,
defining the level of service provided to the customer. 7signal Sapphire enables users to
monitor the fulfillment of the various performance level guarantees defined in the SLA.
The user may freely choose the performance indicators to be monitored in the
service level agreement, in effect forming out of them an SLA group.
19.2 Defining SLA Key Performance Indicators (KPI)
In 7signal Sapphire an SLA group is formed out of a set of Key Performance Indicators
corresponding to the SLA. The SLA group is bound to a topology element in the monitored
network. If an SLA group is not bound to a topology element, 7signal Sapphire applies the
default SLA group, or if not defined, the SLA limits defined for KPIs in the SLA template.
An SLA group consists of several KPIs which define the boundary values used in monitoring the
fulfillment of the service level agreement.
In the 7signal Sapphire system the boundary values can be set separately for each KPI
contained in the SLA group. Each KPI defines a certain type of boundary value and percentage
values for how many measurement samples may fall outside the defined boundary values
without causing the service level agreement to be considered unfulfilled. The type of the KPI
determines whether measurement samples with values over or under the boundary value are
desired.
Three color coding is used for service levels in the KPIs: green, yellow and red. The percentage
boundaries are defined for green and yellow levels of service.
To attain the green level of service the percentage of measurement samples that fulfill the
boundary value criteria set in the KPI (that is, are over or under the set boundary value,
depending on the type of KPI) must be at least as high as the percentage boundary value set
for the green level in the KPI. If there are too many measurement samples that do not fulfill

7signal Solutions, Inc., 526 S. Main Street, Akron, Ohio 44311, USA, 855-763-9526, info@7signal.com, www.7signal.com
7signal Sapphire Carat User Guide Release 5.0
the boundary value criteria, the service level falls to yellow. The yellow level functions likewise:
if it is not attained, the service level falls to red.
As an example, the table below explains how an SLA value is calculated for Upload Throughput
KPI, its measurement and statistical analysis.
Boundary value
above 5,5 Mbit/s
The threshold value for KPI.
Green level
99,0%
At least 99,0% of measured samples must attain
an upload throughput of at least 5,5Mbit/s in
order to attain the green level for the KPI in
question.
Yellow level
95,0%
If the percentage of measured samples that
satisfy the boundary value criteria falls between
95,0% and 99% the yellow level is attained.
Red level
below 95,0%
If the percentage falls below 95,0% the service
level can be considered unfulfilled.
19.3 Creating an SLA group
An SLA group can be created in one of two ways:
1. By copying an SLA template
2. By creating an empty SLA group and adding to it the desired Key Performance
Indicators
When the desired set of KPIs has been added to the SLA group the KPI boundary values can be
set to match the service levels outlined in the actual Service Level Agreement contract.
19.3.1 Creating an SLA group from a template

19.4 SLA propagation
An SLA Group can be bound to any topology element type. In order to avoid unnecessary
binding of the same SLA Groups to multiple topology elements, there is a propagation
hierarchy how SLA Groups are propagated from different levels within the topology hierarchy.
This means that for example if SLA Group is only bound to Top level organization, it is
propagated to each element under the organization. On the other hand, if an SLA Group is
explicitly bound to a topology element, this SLA Group is always applied to the topology
element.
The following figure depicts the SLA propagation order:
Propagation rules are the following:
Wireless network inherits from Organization.
o If the Organization does not have a bound SLA Group, Wireless network
inherits SLA Group from parent Organization of its own Organization.
Link inherits from Access Point or Link Group.
o If both have an SLA Group, SLA Group is inherited from the Access Point.
o If the Access Point does not have a bound SLA Group, the Link inherits the
Group from Eye, etc.
o If the Link Group does not have a bound SLA Group, the Link inherits the
Group from the Location, etc.

Link Group inherits from Location.
o If the Location does not have a bound SLA Group, the Link Group inherits from
parent Location or Organization, etc.
Access Point inherits from Eye.
o If the Eye does not have a bound SLA Group, the Access Point inherits from
Service Area, etc.
Eye inherits from Service Area.
o If the Service Area does not have a bound SLA Group, the Service Area inherits
from Location, etc.
Service Area inherits from Location.
o If the Location does not have a bound SLA Group, the Service Area inherits

Location inherits from parent Location or Organization.
o If the parent Location or Organization does not have a bound SLA Group, the
Location inherits from parent Location or Organization, etc.
Organization inherits from parent Organization.
Management GUI shows the bound or inherited SLA group:
1. In Network Topology select a topology element
2. Right-click and select “Bind SLA”
If the SLA Group is explicitly bound to the topology element, the bound SLA Group can be seen
in the selected state:

20 CONTINUOS AND AUTOMATED REPORTING
Analyzer is an interactive tool for studying network phenomena of interest and for in-depth
investigation of problems. Reports in standard, easy-to-interpret formats are available to
support routine monitoring.
By using the report view in Carat, the user can configure reports from elements that are
familiar from Analyzer. In addition to the user-selected indicators, a report configured here
contains the time of compilation and delivery and a list of the delivery addresses. At the
specified time, Carat generates the report and delivers it to the recipients, specified as either
e-mail addresses or directories in the Carat server file system. A report can include KPIs,
service level views, and alarms, referred to below as report items.
Note: Configuring the mail server settings found under “Edit | SMTP server”
enables the use of email in reporting.

21.2 Importing access point names (“last digit zero” mode)
21.2.1 Overview
This import mode is useful for importing access point names to the system from e.g. Cisco
controller output. The last digit of a Cisco access point MAC address is zero, last digit of BSSIDs
of the access point are non-zero.
For example:
Access point MAC address: 58:BC:27:5D:8B:B0
MAC address of first BSSID: 58:BC:27:5D:8B:B1
MAC address of second BSSID: 58:BC:27:5D:8B:B1
MAC address of third BSSID: 58:BC:27:5D:8B:B2
Access point name list exported from WLAN controller lists the access point names and their
MAC addresses:
Test-AP-1 58:BC:27:5D:8B:A0
Test-AP-2 58:BC:27:5D:8B:B0
Test-AP-3 58:BC:27:5D:8B:C0
Importing names for all BSSIDs of the access point can be done by using this import type.
21.2.2 Running import
1. Select a separator character according to field separator character in the file to be
imported.
2. If the file contains header lines that should be ignored, select correct number of lines
in “Header ignored lines” drop-down menu.
3. If the file contains footer lines that should be ignored, select correct number of lines in
“Footer ignored lines” drop-down menu.
4. If the file contains comment lines that start with a specific character, select a comment
line start character in “Comment line start” drop-down menu.
5. Select the BSSID column number in the file. “0” means first column, “1” means second
column, etc. BSSID here means access point MAC address (which has last digit zero).
6. Select the AP name column number in the file. “0” means first column, “1” means
second column, etc.
7. Select the file to be imported by clicking “Select file..” button.
8. Select “Import file”.
9. Check status of the import in “Import status” field.

23 CHANGE EVENTS
There can be events on wireless networks that impact measurement results of 7signal
Sapphire. Such events can be e.g. controller software update, configuration changes in access
points, power level changes etc. Because the changes affect to measurement results, 7signal
Sapphire provides a method, change event framework, for attaching change information to
measurement results.A change event can be logged for
access points
access points managed by specific Eye

If the database contains huge amount data that is going to be purged, the purge
process may take very long time, even several days.
26.2 Database backup
It is possible to backup databases in 7signal Sapphire. Given a proper backup, the system state
may be recovered completely in case of system crash. There are two remarkably different
alternatives and an option not to backup the database. The default in 7signal Sapphire is no
backup. While this option is known to be non-optimal for any production environment, it is
chosen as default to force every organization to define own backup policy.
26.2.1 Backup options
The backup process will use /tmp directory by default and take a lot of disk space.
It is highly recommended that the default backup work directory is changed to
directory residing on a large file system (not the file system on which the actual
database resides). The directory can be changed with 7db-utility.
Example:
# 7db backup workdir set /largefilesys
Automated backup with server downtime
Backup with downtime is a circadian backup that pauses the measurements by stopping the
Carat server and closing the underlying database connections. In quiescent mode a full backup
of the database is made and stored to the desired location in the Carat server file system. The
user is responsible for managing the backup files, moving and purging and so on. This type of
logging is later referred as offline backup.

7signal Sapphire Carat User Guide Release 5.0
Example:
# 7db backup set daily 03:00 /mnt/backups
Automated backup without server downtime
Online backup is a circadian backup that keeps 7signal Sapphire in production while creating
the backups.
Database logging method must be archival logging.
Example:
# 7db backup set daily 03:00 /mnt/backups
# 7db backup set type online
Manual backup
Circular logging
Sapphire processes will be stopped during backup process and automatically restarted after
backup has been created.
Example:
# 7db backup now /mnt/backups offline
Archival logging
Sapphire processes will not be stopped during backup process.
Example:
# 7db backup now /mnt/backups online
26.2.2 Database logging
In short, the logs of a database system are the most precious. It is justified to say that the logs
are the database as they are written first and the tables are updated after that.
IBM DB2 provides alternative logging methods that affect the backup options. So called
'circular logging' method keeps the size of the logs very predictable. The other option used in
7signal Sapphire is so called 'infinite archive logging'. This is very flexible a logging method
provided that there is a special file system available. Practically the file system must not fill up
ever.
The default logging method in 7signal Sapphire is 'circular logging'.
Purging database logs
Circular logging
26 7signal solution 139
7signal Solutions, Inc., 526 S. Main Street, Akron, Ohio 44311, USA, 855-763-9526, info@7signal.com, www.7signal.com
7signal Sapphire Carat User Guide Release 5.0
There is no need for purging in case of circular logging. The default logging method in 7signal
Sapphire is 'circular logging'.
Infinite archive logging
There is one secure way of purging the log files in the infinite archive directory. Offline backup
has to be done and this comes with price of the 7signal Sapphire halt. Offline backup provides
one single and unique point-in-time to be restored later. Once the offline backup exists, the
log files in the infinite archive directory become obsolete and may be removed.
The other option comes with no warranty whatsoever. The option is to keep 7signal Sapphire
running and to delete log files in the infinite archive directory. To understand what files are
likely to be unused, the active log files has to be followed to see the time to fill up a single log
file and then deduce what infinite archive files might be available for deleting . If one chooses
this option, setting the safety margins reasonably high is advisable.
In case there is both a system crash and a log file has been deleted too early, the
recovery shall never be able to finish. In this case, the only consistent system
stage is available at offline backup time.
The automated reporting lessens the impact of possible data loss if used in detail
and frequently. However, possibility to measurement drill-in analysis is lost as
well as any change in the network topology and other management information.
The infinite archival logging is provided in order to support online backups (see below) but it
should also be seen as a method to make system run longer automatically without user
interruption. However, the system has to be maintained and administered. It is outside of the
scope of this document to fit 7signal Sapphire to IT processes of all organizations but offline
backups with planned system halts are highly recommended.
26.2.3 Backup method options
Default state (not recommemded)
Essentially the 7signal Sapphire system default state is not a backup system at all but it is
based on the underlying database management system's robustness, fault tolerance and basic
level recovery options. In case of a permanent disk failure the data is lost. By installing the
databases on RAID disks lessens the risk further.
On default state the 7signal Sapphire relies on the database management system (IBM DB2)
logging. The assumptions are that the management information (Eye, access point and target
network) changes are not continuous but rather sporadic. The measurements are continuous
but losing few of the most recent samples is a risk that can be tolerated. Typical starting point
for analysis is one week of measurements and in case of sudden system down one would lose
the data until the system is fixed. And in case of system down it is expected that all the efforts
shall be there to bring 7signal Sapphire and other systems online again. There shall be no
special snapshots where to start operations again. It is possible to resume a state before the
interrupt, possibly the system is operational with no special effort at all.

7signal Sapphire Carat User Guide Release 5.0
Offline backups are possible but require user actions both to shutdown 7signal Sapphire and
do the actual backup.
Handicaps of the default method:
- no precise and secure backup (system state) to return to by default
- backup process is completely manual
- backup process requires downtime
Method strengths:
- least planning
- least resource consuming
First degree of backup: offline backup
Most importantly this method gives fully recoverable snapshots at the desired intervals. The
disk space requirement is an issue but not extremely serious as the frequency is totally user-
managed and the file size growth is easy to check (with the tools provided by the operating
system, not by 7signal). The downside is the downtime as the 7signal Sapphire must be halted
for the time of the backup, hence it is called offline backup. Typically this would be rather
minutes than tens of minutes. Naturally all the measurements are stopped for that time.
Offline backup 1st degree is available in every install and run scenario of 7signal Sapphire. One
can start offline backup with a tool or have it run by the system in a circadian manner.
Method handicaps:
- backup process requires downtime
Method strengths:
- simple to recover
- recovered system state is thoroughly consistent
TIP: offline backup is suitable for environments that require automated backup
but do have neither special backup policy hardware nor other extensive
resources.
2nd degree of backup: online backup
The requirement for the online backup is that infinite archive logging is enabled.
When online backup is operational, the most significant benefit is the ability to run circadian
backups online i.e. 7signal Sapphire remains operational and continues testing while creating
the backup. As opposed to offline backup, the system is online all the time producing
measurements.
The first and the most important assumption is that there is a storage device available that in
practice is a so-called endless device. 7signal cannot and shall not guarantee any checks on the
device but it is assumed to be available all the time and have the capacity for massive data
transfers. The user is responsible for the storage capacity.
NOTE: backups are not done incrementally in any case. This means that over time
the needed to dump the database increases but more importantly the disk space
requirement increases continuously.

7signal Sapphire Carat User Guide Release 5.0
NOTE: use of backup systems requires planning and administration i.e. continuous
effort from the administrator. This area is outside of 7signal scope, 7signal
encourages clear planning on the issue.
During installation there shall be various destination folders inquired by the install script. The
folders are for logs, for backup files etc. As complex as online backup may sound, the setting of
the online backup is easy. To maintain and keep it available and functional requires IT support
that is beyond the scope of 7signal guidance.
Behind the scenes the technology relies completely on IBM DB2 backup system and 7signal
provides interface that covers and automates IBM interface to support 7signal databases.
TIP: there are environments that require separate hardware for backups. If
possible, 7signal Sapphire should be integrated (on file system level) to these.
TIP: with frequent and detailed automated reports the loss of measurement data
becomes less drastic as the needed information may be found in the reports.
Changing log settings
Install time gives the option to set all the backup related settings including log setup.
To change the settings while the system is installed and in production later, please use the tool
7db and the logsetup sub-command. Complete guide to 7db tool is in the appendix of
Deployment Guide.
Managing backup levels
By default the system is in default state, no automated backups at all. Any change to that state
would require more resources and administration that should be planned separately.
In case one has changed the default settings – either by giving such install parameters or
issuing the needed commands after the installation - the following operations return the initial
state:
1) stop circadian backups
2) set logging to circular mode
This implies that the default state means circular logging without circadian backups.
File system settings for the database
There are three elements that require – optimally separate – disk space:
1. databases
a. measurement database
b. management database
c. security database
2. database logs
3. database backups
26 7signal solution 142

7signal Sapphire Carat User Guide Release 5.0
Naturally the backups must be stored separately from the logs and the databases; otherwise
the value of the backups reduces significantly. The databases and the related logs are expected
to be accessible easily from the hosting server but it is encouraged to use separate physical file
systems for these two.
NOTE: log files and databases residing in the same physical disk mean duplicate
disk operation efforts on the same device. It is good design to separate logs and
actual databases to different physical storage devices.
Changing backup settings
Install time gives the option to set all the backup related settings.
To change the settings while the system is installed and in production later, please use the tool
7db and the backup sub-command. Complete guide to 7db tool is in the appendix of
Deployment Guide.
Below there are example commands to give the reader an overview:
# 7db backup remove
# 7db backup set weekly Wed 00:30 /mnt/backups # 7db backup set daily
03:00 /mnt/backups
# 7db backup set directory /mnt/newbackups
# 7db backup set weekly Sun 01:30
# 7db backup set type online
# 7db backup now /mnt/backups online
26.2.4 Restoring backups
Backups are located in the user-defined directory. Backup files contain timestamp in the name;
also the operating system timestamp exists.
NOTE: the user must be aware which backup file should be used. Therefore it is
essential to understand the backup system and the related files.
Based on this information one must choose which backup to restore.
Restore command is
# 7db backup restore <absolute-file-path>
NOTE: while issuing restore command when using online backup, it might be
necessary for the system to retrieve files from the infinite archive directory when
the restore command is issued. The access time is affected by the physical device.
If the system cannot access the files, restore shall not happen. The most recent
offline backup is the alternative point of recovery.

26.4 Reorganizing measurement database
In order to maintain optimal performance of the measurement database, the database needs
be reorganized periodically. This can be done e.g. before offline backup.
Login to the server that hosts the Carat server as root user and execute the measurement
database reorganization command:
# 7db reorg meas7
The reorganization tool first checks if reorganization is needed for each table. If so, it executes
DB2 reorganization command.

27 NAGIOS SUPPORT
7signal Sapphire supports Nagios, a commonplace open license tool for IT infrastructure
monitoring.
In this case Sapphire is the object of monitoring, not the monitor itself. Therefore we assume
the general concepts and usage of Nagios to be well-known to the user. If this is not the case,
one may start exploring the topic from the Nagios web pages (http://www.nagios.org). Also, a
recent Nagios release package is included in the delivery media of the 7signal Solution in Sonar
disk and the folder named "Non-7signal Software"
27.1 Adding Sapphire host information to Nagios server
The prerequisite is that Nagios is installed and running on the host machine. In order to
monitor a remote Carat server do the following steps (as a root user):
1. Modify commands.cfg file (default location: /etc/nagios/object/commands.cfg)
Add:
define command {
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
2. Create configuration file for remote machine running the Carat server to Nagios
objects directory (default location: /etc/nagios/objects)
File extension is cfg, otherwise the naming is free. You may use or modify the
following:
carat-host-xyz.cfg
7signal_wqa_carat_1.cfg etc.
Content of the file:
define host {
use linux-server
host_name <host-name-of-the-monitored-server>
alias <alias-of-the-monitored-server>
address <IP address of the monitored server>
}
define service {
use local-service
host_name <host-name-of-the-monitored-server>
service_description 7signal Sapphire Carat
check_command check_nrpe!check_carat_server
}
3. Add host configuration file (the previous step) to nagios.cfg file (default location:
/etc/nagios/nagios.cfg):
cfg_file=/etc/nagios/objects/carat-host-xyz.cfg
4. Restart Nagios server
service nagios restart

27.2 Adding Nagios Plug-ins To Sapphire Software
The prerequisite is that client-side tools of Nagios have been installed on the host running
7signal Sapphire software. The protocol being used is NRPE. There is no SSH support
concurrently.
27.2.1 Install NRPE daemon
Use online install with yum:
# yum install nrpe
27.2.2 Install toolset ‘Nagios plugins’
Use online install with yum:
# yum install nagios-plugins-nrpe
NOTE: the following installers shall open port tcp/5666 for Nagios traffic in the
firewall settings.Install Sapphire plugin
There folders named Nagios_support on both Carat and Sonar delivery disks. They contain the
following files
7signal-Nagios-plugin-<version-info>-for-Carat-installer.bin
7signal-Nagios-plugin-<version-info>-for-Analyzer-installer.bin
7signal-Nagios-plugin-<version-info>-for-Sonar-installer.bin
The files are executable and totally self-contained. By running each of the file makes the
respective Sapphire Nagios plugin available. The process includes configuration file creation,
updates and firewall settings.
Silent install mode (option -s) uses 7signal defaults for all parameters. If this option is not used,
all parameters are inquired interactively with the default setting visible.
By default, the plugin installations end up in /opt/7signal/nagios folder. However, the
installation makes the plugins available and after this the process and operations are
completely transparent to the Carat user.
27.3 Verifying Nagios Installation
Complete and operational install is achieved if Nagios GUI shows
check_carat_server
check_sonar_server
check_analyzer_server
as options for monitoring for the hosts running 7signal Sapphire software.
27.4 Removing Nagios plugins
The installation directory contains uninstall_nagios.sh that removes Sapphire related
plugin files. The NRPE daemon stays untouched and its configuration is cleaned only for
Sapphire plugins thus NRPE and other Nagios operations remain untouched.
