Prerequisites​

SNMP Configuration​

To use this pack, the SNMP service must be properly configured on your Cisco WLC server. Please refer to the official documentation from CISCO:

Network flow​

The target server must be reachable from the Centreon poller on the UDP/161 SNMP port.

Setup​

  1. Install the plugin package on every Centreon poller expected to monitor Cisco WLC resources:
yum install centreon-plugin-Network-Cisco-Wlc-Snmp
  1. On the Centreon web interface, on page Configuration > Plugin Packs, install the Cisco WLC Centreon Plugin Pack.

Configuration​

Host​

  • Log into Centreon and add a new host through Configuration > Hosts.
  • Fill the Name, Alias & IP Address/DNS fields according to your Cisco WLC server settings.

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

Once the plugin is installed, log into your Centreon poller's CLI using the centreon-engine user account (su - centreon-engine) and test the plugin by running the following command:

/usr/lib/centreon/plugins//centreon_cisco_wlc.pl \
--plugin=network::cisco::wlc::snmp::plugin \
--mode=ap-status \
--hostname=10.0.0.1 \
--snmp-community='my-snmp-community' \
--snmp-version=2c \
--filter-name='' \
--filter-group='' \
--warning-radio-status='' \
--critical-radio-status='' \
--warning-radio-interface-channels-utilization='' \
--critical-radio-interface-channels-utilization='' \
--warning-total='' \
--critical-total='' \
--warning-total-associated='' \
--critical-total-associated='' \
--warning-total-disassociating='' \
--critical-total-disassociating='' \
--warning-total-enabled='' \
--critical-total-enabled='' \
--warning-total-disabled='' \
--critical-total-disabled='' \
--warning-status='' \
--critical-status='' \
--use-new-perfdata

The expected command output is shown below:

OK: total: %s associated: %s disassociating: %s downloading: %s enabled: %s disabled: %s   channels utilization: %s %% | 'accesspoints.total.count'=300;;;0; 'accesspoints.associated.count'=300;;;0; 'accesspoints.disassociating.count'=0;;;0; 'accesspoints.downloading.count'=0;;;0; 'accesspoints.enabled.count'=0;;;0; 'accesspoints.disabled.count'=0;;;0; 'accesspoint.radio.interface.channels.utilization.percentage'=70%;;;0;100 

All available options for a given mode can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins//centreon_cisco_wlc.pl \
--plugin=network::cisco::wlc::snmp::plugin \
--mode=ap-status \
--help

All available modes can be displayed by adding the --list-mode parameter to the command:

/usr/lib/centreon/plugins//centreon_cisco_wlc.pl \
--plugin=network::cisco::wlc::snmp::plugin \
--list-mode
