Prerequisitesβ
Device Configurationβ
The SNMP agent must be configured and running on the Aruba device. Please refer to the manufacturer documentation to achieve this.
Network flowsβ
The Centreon Poller must be able to reach the UDP/161 SNMP port of the Aruba device.
Installationβ
- Online License
- Offline License
- Install the Centreon package on every Centreon Poller expected to monitor Aruba Wireless Access Point equipments:
yum install centreon-plugin-Network-Aruba-Instant-Snmp
- On the Centreon Web interface, install the Aruba Instant SNMP Monitoring Connector through Configuration > Monitoring Connectors Manager page.
- Install the Centreon package on every Centreon Poller expected to monitor Aruba Wireless Access Point equipments :
yum install centreon-plugin-Network-Aruba-Instant-Snmp
- Install the Centreon Monitoring Connector RPM on the Centreon Central server:
yum install centreon-pack-network-aruba-instant-snmp
- On the Centreon Web interface, install the Aruba Instant SNMP Monitoring Connector through Configuration > Monitoring Connectors Manager page.
Host configurationβ
Create your Host and apply the Net-Aruba-Instant-SNMP-custom Host Template. You must set SNMP Community and Version in the dedicated fields of the Host Form.
When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters More information in the Troubleshooting SNMP section.
Obligatoire | Nom | Description |
---|---|---|
SNMPEXTRAOPTIONS | Configure your own SNMPv3 credentials combo |
How to test my plugin and what do the main parameters stand for ?β
Once the plugin is installed, you can test it logging into the CLI with the centreon-engine user.
/usr/lib/centreon/plugins//centreon_aruba_instant_snmp.pl --plugin=network::aruba::instant::snmp::plugin \
--mode=ap-usage \
--hostname=10.30.2.11 \
--snmp-version='2c' \
--snmp-community='test/aruba' \
--filter-name='' \
--warning-status='' \
--critical-status='%{status} !~ /up/i' \
--warning-cpu='' \
--critical-cpu='' \
--warning-clients='20' \
--critical-clients='50' \
--warning-mem-usage='' \
--critical-mem-usage='' \
--warning-mem-usage-free='' \
--critical-mem-usage-free='' \
--warning-mem-usage-prct='' \
--critical-mem-usage-prct='' \
--verbose
The command above collects usage data for an Aruba access point (--mode=ap-usage
). Mandatory options are the IP/FQDN of the device
(--hostname=10.30.2.11
) and the SNMP version you have set on your appliance (--snmp-community='test/aruba'
).
This command would trigger a WARNING alarm if the number of clients connected to the device is greater than 20 (--warning-clients='20'
) and
a CRITICAL alarm if the number of clients connected to the device is greater than 50 (--critical-clients='50'
).
All available options for a given mode can be displayed by adding the --help
parameter to the command:
/usr/lib/centreon/plugins//centreon_aruba_instant_snmp.pl \
--plugin=network::aruba::instant::snmp::plugin \
--mode=ap-usage \
--help
All plugin modes can be listed with the following command:
/usr/lib/centreon/plugins//centreon_aruba_instant_snmp.pl \
--plugin=network::aruba::instant::snmp::plugin \
--list-mode
Troubleshootingβ
UNKNOWN: SNMP GET Request : Timeoutβ
If you get this error, it may indicate that some flows are blocked between the Centreon Poller and the Aruba devices.
It can also mean that the Centreon Host Configuration doesn't reflect the SNMP configuration on Aruba side (version, community).
UNKNOWN: SNMP GET Request : Cant get a single value.β
You may get this error when SNMP privileges are not wide enough. You can check that the SNMP community used in your command line has enough rights to walk the Aruba entreprise SNMP branch: .1.3.6.1.4.1.14823
You can use the snmpwalk utilities which is provided through net-snmp package.
