Cisco Telepresence System SNMP

Overview

Cisco Telepresence System is part of the Cisco Unified Communication suite to offer high quality collaboration tools with video and audio capabilities.

Monitoring Connector assets

Monitored objects

• Peripherals status and metrics
• Calls history and streams

mediatype#calls.streams.active.packetloss.in.percentage	Packet Loss In rate on ongoing call	%
mediatype#calls.streams.active.packetloss.out.percentage	Packet Loss Out rate on ongoing call	%

Peripherals

Metric name	Description	Unit
peripherals.total.count	Number of pysical entity on the CTS
Peripheral Status	Operating status of each peripheral (MIC, CAM, DISPLAY)

Prerequisites

The SNMP service must be installed and configured on the Cisco CTS Device. The Centreon Pollers must as well be able to reach the CTS over the UDP/161 port.

More information about how to configure your CTS can be found in the official documentation: https://www.cisco.com/c/en/us/td/docs/video/cuct/1_1/english/configuration/guide/maint.html.

Setup

Online License

1. Install the Centreon package on every Centreon poller expected to monitor Cisco CTS ressources:

yum install centreon-plugin-Hardware-Devices-Cisco-Cts-Snmp

2. On the Centreon Web interface, install the Cisco CTS Centreon Monitoring Connector on the Configuration > Monitoring Connector Manager page

Offline License

1. Install the Centreon package on every Centreon poller expected to monitor Cisco CTS applications:

yum install centreon-plugin-Hardware-Devices-Cisco-Cts-Snmp

2. Install the Centreon Monitoring Connector RPM on the Centreon Central server:

yum install centreon-pack-hardware-devices-cisco-cts-snmp

3. On the Centreon Web interface, install the Cisco CTS Centreon Monitoring Connector on the Configuration > Monitoring Connector Manager page

Configuration

• Log into Centreon and add a new Host through "Configuration > Hosts".
• Fill the "Name", "Alias", "IP Address / DNS", "Snmp Community" and "Snmp version" fields according to your device's configuration
• Select the HW-Device-Cisco-Cts-SNMP.

When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters More information in the Troubleshooting SNMP section.

Mandatory	Name	Description
	SNMPEXTRAOPTIONS	Configure your own SNMPv3 credentials combo

FAQ

How to check in the CLI that the configuration is OK and what are the main options for ?

Once the plugin installed, log into your Centreon Poller CLI using the centreon-engine user account and test the Plugin by running the following command (some of the parameters such as --snmp-community have to be adjusted):

/usr/lib/centreon/plugins/centreon_cisco_cts_snmp.pl \
--plugin=hardware/devices/cisco/cts/snmp/plugin.pm \
--mode=peripherals \
--hostname='10.2.15.12' \
--snmp-version=2c \
--snmp-community='snmp-community' \
--critical-total='13:' \
--verbose

Expected command output is shown below:

OK: Total peripherals: 13 - All peripherals are ok | 'peripherals.total.count'=13;;;0;
Peripheral 'UP_LINK' status: noErrorPeripheral 'MIC -- front_center' status: noError
Peripheral 'MIC -- front_left' status: noError
Peripheral 'MIC -- front_right' status: noError
Peripheral 'MIC BOARD -- mic_array_board' status: noError
Peripheral 'MAIN_CAM -- Serial=XXXXX39,PID=CTS-5K-CAM-CLSTR,Hardware_ver=03.00,Firmware=0,BuildTime=year:2016,week:19' status: noError
Peripheral 'DISPLAY_LEFT -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError
Peripheral 'DISPLAY_RIGHT -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError
Peripheral 'AUX_DISPLAY_LEFT -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError
Peripheral 'AUX_DISPLAY_CENTER -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError
Peripheral 'AUX_DISPLAY_RIGHT -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError
Peripheral 'UI_DEVICE --  MAC address : 00:11:EE:9Y:48:15 Version : 11-0-1KKPL-437' status: noError
Peripheral 'MAIN_DISPLAY -- Serial=XXXXX39,Hardware_ver=,Model=CTS-5K-70-G1 ,Manufacturer=CIS(0x0d33),AppCode_Ver=(unsupported)' status: noError

In this example, the Plugin gets the number of physical peripherals and their operating status (--plugin=hardware/devices/cisco/cts/snmp/plugin.pm --mode=peripherals) by requesting the Cisco Telepresence MIB on the Cisco CTS Device.

This command would trigger a CRITICAL alarm if the number of detected peripherals is less than 13 --warning-total='13:').

All the available thresholds parameters can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/centreon_cisco_cts_snmp.pl \
--plugin=hardware/devices/cisco/cts/snmp/plugin.pm \
--mode=peripherals \
--help

UNKNOWN: SNMP GET Request : Timeout

If you get this message, you're probably facing one of theses issues:

• Your SNMP isn't started or misconfigured on the Cisco CTS device
• An external device is blocking your request (firewall, ...)

UNKNOWN: SNMP GET Request : Cant get a single value.

This message generally means that SNMP privileges are not wide enough for the mode/plugin to work properly or that the polled device doesn't support CISCO-TELEPRESENCE-MIB.
