  • Copy the check (python script) in your nagios/centreon plugins folder
  • Create a check with the following command line:
    $USER1$/plugins_custom/ -u $_HOSTCLOUDUSER$ -p $_HOSTCLOUDPWD$ -H $HOSTNAME$ -c $ARG1$ --ignore-proxy
    or for the check: uploadFilesize
    $USER1$/plugins_custom/ -u $_HOSTCLOUDUSER$ -p $_HOSTCLOUDPWD$ -H $HOSTNAME$ -c $ARG1$ --upload-filesize=$ARG2$ --ignore-proxy
  • Create a service for each thing you want to check (system, storage, etc.) and link it to your host(s)
  • Add the credentials of your nextcloud admin user as custom macro (CLOUDUSER, COUDPWD) to your host.

Example 1

./ -u adminUser -p secretPassword -H -c system --ignore-proxy

OK - Nextcloud version:

Example 2

./ -u adminUser -p secretPassword -H -c activeUsers --ignore-proxy

OK - Last 5 minutes: 3 user(s), last 1 hour: 10 user(s), last 24 hour: 44 user(s) | users_last_5_minutes=3, users_last_1_hour=10, users_last_24_hours=44

This will return a status message and create a graph based on the performance data.

Example 3

./ -u adminUser -p secretPassword -H -c uploadFilesize --upload-filesize=2.0GiB --ignore-proxy

OK - Upload max filesize: 2.0GiB

# Or, when changed after an update...

CRITICAL - Upload max filesize is set to 512.0MiB, but should be 2.0GiB
