Re: Performance Graph issue on some servies
If the amount of datasources changed from the command, it is usually best to remove the rrd file and let them re-create, because the old data is not likely is the same location in the rrd.
I would remove the Memory_Usage.rrd & CPU_Usage.rrd and let nagios re-create them (takes 5-15 minutes)
you could just move them to a temp location if you like

Code: Select all
mv Memory_Usage.rrd /tmp
mv CPU_Usage.rrd /tmp
