Polycom RPRM SNMP

Overview​

The RealPresence Resource Manager system is a management solution that provides unified management of the Polycom® RealPresence® Clariti™ and video and audio endpoints. Unified management features include license management, monitoring, conference scheduling, and provisioning of Polycom video infrastructure products and as well as both Polycom and third-party endpoints within your environment.

The Centreon Monitoring Connector relies on the SNMP protocol to query and collect status and metrics of the Polycom RPRM solution.

Monitoring Connector assets​

Monitored objects​

  • RPRM Devices and associated resources (sites, sitelinks...)

Collected metrics​

Metric nameDescription
cluster-statusCurrent status of the RPRM SuperCluster
cluster-change-causeReason of the last cluster state change

Prerequisites​

Device Configuration​

Configure the proper SNMP settings on your Polycom RPRM device according to the Polycom official documentation: https://documents.polycom.com/bundle/rprm-ops-10-5/page/rprm_ops/SNMP_Operations/SNMP_Operations.htm

Network flows​

The Centreon Poller must be able to reach the UDP/161 SNMP port of the Polycom RPRM device.

Installation​

  1. Install the Centreon package on every Centreon Poller expected to monitor Polycom RPRM devices:
yum install centreon-plugin-Hardware-Devices-Polycom-Rprm-Snmp
  1. On the Centreon Web interface, install the Polycom RPRM SNMP Monitoring Connector through Configuration > Connectors > Monitoring Connectors page.

Host configuration​

  • Add a new Host and apply the HW-Device-Polycom-Rprm-SNMP-Custom Host Template
  • Fill the SNMP Version and Community fields according to the device's configuration

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

FAQ​

How to test the Plugin 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:

/usr/lib/centreon/plugins/centreon_polycom_rprm_snmp.pl \
    --plugin=hardware::devices::polycom::rprm::snmp::plugin \
    --mode=sites \
    --hostname=10.0.0.1 \
    --snmp-version='2c'
    --snmp-community='mysnmpcommunity' \
    --warning-site-bandwidth-used-prct='80' \
    --critical-site-bandwidth-used-prct='90' \
    --warning-site-packetloss-prct='5' \
    --critical-site-packetloss-prct='10' \
    --verbose

Expected command output is shown below:

OK: Total sites : 1 - Site 'My_Poly_Site_1' current active calls : 27, current bandwidth usage : 12.50 %, Total allowed bandwidth: 25.00 Mb/s, 
Average call bit rate : 1.11, Average packetloss : 1.03 %, Average jitter time : 0.77 ms, Average delay time : 1.10 ms | 
'rprm.sites.total.count'=3;;;0; 'My_Poly_Site_1#rprm.site.calls.active.count'=27;;;0; 'My_Poly_Site_1#rprm.site.bandwidth.used.percentage'=12.50%;80;90;0;100 
'My_Poly_Site_1#rprm.site.bandwidth.total.bytespersecond'=25000000.00B/s;;;0; 'My_Poly_Site_1#rprm.site.callbitrate.average.ratio'=1.11;;;0; 
'My_Poly_Site_1#rprm.site.packetloss.average.percentage'=1.03%;5;10;0;100 'My_Poly_Site_1#rprm.site.jitter.average.milliseconds'=0.77ms;;;0; 'My_Poly_Site_1#rprm.site.delay.average.milliseconds'=1.10ms;;;0;
Site 'My_Poly_Site_1' current active calls : 27, current bandwidth usage : 12.50 %, Total allowed bandwidth: 25.00 Mb/s, 
Average call bit rate : 1.11, Average packetloss : 1.03 %, Average jitter time : 0.77 ms, Average delay time : 1.10 ms

The command above monitors the sites managed by a RPRM device (--plugin=hardware::devices::polycom::rprm::snmp::plugin --mode=sites) identified by the IP address 10.0.0.1 (--hostname=10.0.0.1). As the Plugin is using the SNMP protocol to request the device, the related community and version are specified (--snmp-version='2c' --snmp-community='mysnmpcommunity').

This command would trigger a WARNING alarm if the bandwidth used raises over 80% of the site bandwidth capacity (--warning-site-bandwidth-used-prct='80') and a CRITICAL alarm over 90% (--critical-site-bandwidth-used-prct='90'). WARNING/CRITICAL alarms would aslo be triggered if the packet-loss percentage rate raises over 5%/10% (--warning-site-packetloss-prct='5' --critical-site-packetloss-prct='10').

For each Plugin mode, all the options as well as all the available thresholds can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/centreon_polycom_rprm_snmp.pl --plugin=hardware::devices::polycom::rprm::snmp::plugin --mode=sites --help

How to monitor system metrics on the Ploycom RPRM ?​

Polycom RPRM devices are Linux-Based, use the OS-Linux-SNMP-Custom Host Template in addition with the RPRM Template to monitor the operating system layer.

UNKNOWN: SNMP GET Request : Timeout​

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

  • The SNMP agent of the device isn't started or is misconfigured
  • An external device is blocking the request (firewall, ...)
