Check disks FS usage of *nix based servers using the Netdata agent RestAPI.
|
|
|
|
Example:
|
|
perl centreon_plugins.pl --plugin=apps::monitoring::netdata::restapi::plugin
|
|
--mode=disks --hostname=10.0.0.1 --chart-period=300 --chart-statistics=average --warning-usage-prct=80 --critical-usage-prct=90 --verbose

|
=item B<--chart-period>
|
|
|
|
The period in seconds on which the values are calculated
|
|
Default: 300
|
|
|
|
=item B<--chart-statistic>
|
|
|
|
The statistic calculation method used to parse the collected data.
|
|
Can be : average, sum, min, max
|
|
Default: average
|
|
|
|
=item B<--fs-name>
|
|
|
|
Filter on one or more specific FS. Regexp can be used
|
|
Example: --fs-name='(^/$|^/boot$)'
|
|
|
|
=item B<--warning-usage>
|
|
|
|
Warning threshold on FS space usage (in B).
|
|
|
|
=item B<--critical-usage>
|
|
|
|
Critical threshold on FS space usage (in B).
|
|
|
|
=item B<--warning-usage-prct>
|
|
|
|
Warning threshold on FS percentage space usage (in %).
|
|
|
|
=item B<--critical-usage-prct>
|
|
|
|
Critical threshold on FS percentage space usage (in %).
|
|
|
|
=item B<--warning-free>
|
|
|
|
Warning threshold on FS free space.
|
|
|
|
=item B<--critical-free>
|
|
|
|
Critical threshold on FS free space.
|
|
|
|
=item B<--space-reservation>
|
|
|
|
On specific systems, partitions can have reserved space (like ext4 for root).
|
|
This option will consider this space in the calculation (like for the 'df' command).
