No Performance graph showing

[ar0431]

No performance graph showing. Performance graph was showing before but not now. How I can troubleshoot it.

I am receiving this error in the log file /usr/local/nagios/var/perfdata.log

RRDs::update ERROR Unable to connect to rrdcached: No such file or directory

Hello @ar0431,

According to the error message, it looks like the daemon is not running. Let's run the following commands and post the output to verify the status.

Code: Select all

systemctl status rrdcached
ls -la /tmp/rrd.journal*
### Check disk space
df -h

Just to verify, did you follow these instructions for installing rrdcached? Thanks.

Sorry, I actually accidentally turn-on the option "rrd_daemon_opts" in the /usr/local/nagios/etc/pnp/process_perfdata.cfg file. I just restart the npcd service again and now graphs are working fine. I will read about "rrdcached" and then I will try it.

Glad to hear it's working. I'll keep this thread open for now and just let us know if you have any other questions.
