I am actually running RHEL5.2 server x64 with Nagios3.2.3 with nagiosgraph1.4.3.

I am having some weird issue with nagiosgraph and getting RRD data.
What's happening is, some data gets populated, some other doesn't.

for example, I am monitoring the partition on my nagios server. I have 4 partition, /, /var, /tmp, /usr, which I monitor separately. I am getting data for 3 of them, and not getting any for /tmp.
I am using the same command for all 4 of them. Only the file system changes. I am also mapping the perfdata using the same regexp.

Nagios.log and nagiosgraph.log doesn't show errors and /tmp doesn't show in nagiosgraph, but there are schedule running for all 4 partition.

I suppose that there is no perfdata being pushed from nagios, but why would it push perfdata for 3 of the 4 partition?

Can anyone point me where to look or how to proceed to find out what's happening?

I would also post my config file, but they are on a separate network.

thanks
