Please note that the only procedures supported and maintained by Centreon are those published in the official documentation. If you have a question about this article, post it in the comments.
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.
