Hello,

We recently upgraded some of our monitors that were using NSClient to NCPA 2.2.1 and noticed that the memory checks aren't displaying performance graph data. All other checks such as cpu usage, disk usage, bandwidth, swap usage, system uptime are displaying performance graph data. However, we did build out a few new monitors using NCPA 2.2.1 on servers that did not previously have any prior agents on them and they are displaying memory usage performance graph data. After reading around, I deleted the .rrd file associated with the service using:

Code: Select all

rm -f /usr/local/nagios/share/perfdata/HOSTNAME/SERVICEDESC.rrd

Deleting the associated .rrd file did not resolve the issue. Any way we can get this resolved?

Can you show the Advanced tab for this service on the Service Status Detail page

Sorry for the delayed response on this. I attached a screenshot of the Advanced tab for a memory service monitor that isn't showing historical data

This all looks correct, and you get nothing in the graph after deleting the rrd and letting it get rebuilt?

The rrd does get re-created correct?
