To monitor your Ubiquiti UniFi, the SNMP must be configured. The Poller should be able to perform SNMP requests toward the Ubiquiti device over SNMP UDP/161 port.


  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Ubiquiti-Unifi-Snmp
  1. On the Centreon Web interface in Configuration > Monitoring Connectors Manager, install the Ubiquiti UniFi SNMP Pack

Host configuration​

  • Add a new Host and fill the IP Address/FQDN, SNMP Version and SNMP Community fields according to the device's configuration
  • Apply the Net-Ubiquiti-Unifi-SNMP-custom Host Template

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

SNMPEXTRAOPTIONSConfigure your own SNMPv3 credentials combo

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/ \
--plugin=network::ubiquiti::unifi::snmp::plugin \
--mode=disks \
--hostname= \
--snmp-version='2c' \
--snmp-community='ubiquiti_ro' \
--filter-disk-path='^/$' \
--warning-usage-prct='90' \
--critical-usage-prct='95' \

Expected command output is shown below:

OK: Partition '/' usage total: 46.82 GB used: 26.41 GB (56.40%) free: 20.41 GB (43.60%), Inodes used: 2 % | 'storage.partitions.count'=1;;;0; '/'=28356739072B;;;0;50273779712 '/'=21917040640B;;;0;50273779712 '/'=56.40%;0:90;0:95;0;100 '/#storage.inodes.usage.percentage'=2%;;;0;100
Partition '/' usage total: 46.82 GB used: 26.41 GB (56.40%) free: 20.41 GB (43.60%), Inodes used: 2 %

The command above monitors Ubiquiti UniFi (--plugin=network::ubiquiti::unifi::snmp::plugin --mode=disks) identified by the IP address (--hostname= As the Plugin is using the SNMP protocol to request the device, the related community and version are specified (--snmp-version='2c' --snmp-community='ubiquiti_ro').

This command would trigger a WARNING alarm if disk utilization over 90% (--warning-usage-prct='90') and a CRITICAL alarm over 95% (--critical-usage-prct='95').

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/ \
--plugin=network::ubiquiti::unifi::snmp::plugin \
--mode=disks \
