Similar issue is seen with snapshot restore.

When snapshot is restored, brick utilization graph displays max, last and average as -nan% until the next reschedule happens.

Similar issue seen with network utilization graphs too. When a node is just configured for monitoring with nagios, graphs for network utilization service are affected by this issue.

Looks like this is a RRD sync-up issue. We will look into further and update here. Meanwhile could you please attach the plugin xml data file before and after adding host or brick or volume.

Thank you for the bug report. However, closing this as the bug is filed against gluster nagios monitoring for which no further new development is being undertaken.
