No graphs seem to be generated


Badge +3

Symptom

RRD files do not seem to be generated. Graphs cannot be displayed.

 

Verification

Refer to this list of checkpoints to identify where the issue is located.

 

Disk space

By default, the graph files (.rrd) are stored in the /var/lib/centreon/metrics directory. Ensure you have enough space in your filesystem for the storage.

 

Permissions

Ensure the .rrd files can be written in the /var/lib/centreon/metrics and /var/lib/centreon/status/ directories. The process that usually writes in this directory is centreon-broker.

 

Plugins

Ensure your plugin returns the correct output. Refer to this documentation for more information.
