Polycom HDX SNMP
Overview​
The Polycom HDX Room system is an endpoint device that provides voice and video connectivity across collaboration networks.
This Monitoring Connector checks basic system health indicators and video/audio related protocols performances during a call.

Prerequisites​
Device Configuration​
On the Polycom device, enable and configure the SNMP agent:
- Connect to the HDX Admin Web UI
- Go to 'System > Manage > Credentials'
- Create new SNMP credentials specifying community and version
Network flows​
The Centreon Poller must be able to reach the UDP/161 SNMP port of the Polycom HDX device.
Installation​
- Online License
- Offline License
- Install the Centreon package on every Centreon Poller expected to monitor Polycom HDX devices:
yum install centreon-plugin-Hardware-Devices-Polycom-Hdx-Snmp
- On the Centreon Web interface, install the Polycom HDX SNMP Monitoring Connector through Configuration > Connectors > Monitoring Connectors page.
- Install the Centreon package on every Centreon Poller expected to monitor Polycom HDX devices:
yum install centreon-plugin-Hardware-Devices-Polycom-Hdx-Snmp
- Install the Centreon Monitoring Connector RPM on the Centreon Central server:
yum install centreon-pack-hardware-devices-polycom-hdx-snmp
- On the Centreon Web interface, install the Polycom HDX SNMP Monitoring Connector through Configuration > Connectors > Monitoring Connectors page.
Host configuration​
- Add a new Host and apply the HW-Device-Polycom-Hdx-SNMP-Custom Host Template
- Fill 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.
| Mandatory | Name | Description |
|---|---|---|
| SNMPEXTRAOPTIONS | Configure your own SNMPv3 credentials combo |
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_hdx_snmp.pl \
--plugin=hardware::devices::polycom::hdx::snmp::plugin \
--mode=viewstation-stats \
--hostname=10.0.0.1 \
--snmp-version='2c' \
--snmp-community='mysnmpcommunity' \
--warning-h323-packet-loss='5' \
--critical-h323-packet-loss='10' \
Expected command output is shown below:
OK: View Station Phone Number: '0123456789' Stats: H323 Packet Loss 1.00 %, H323 (audio/video) Jitter 30.00 ms, H323 (audio/video) Latency 4.00 |
'h323-packet-loss'=1.00%;;;0;100 'h323-jitter'=30.00ms;;;0;100 'vs_latency'=4.00;;;0;100
The command above monitors the sessions statistics of a Polycom HDX ViewStation device (--plugin=hardware::devices::polycom::hdx::snmp::plugin --mode=viewstation-stats) 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 packet loss rate of the active calls raises over 5% (--warning-h323-packet-loss='5')
and a CRITICAL alarm over 10% (--critical-h323-packet-loss='10').
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_hdx_snmp.pl --plugin=hardware::devices::polycom::hdx::snmp::plugin --mode=viewstation-stats --help
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, ...)
What does the '(skipped: no values)' message mean?​
When using ViewStation-Statistics service, you will get this message when there is no audio and/or video call in progress on the HDX Room system. This is the expected behavior. As soon as a call starts, metrics will get populated.
