Hi,
for some reason we don’t get any graph output on the new added hosts.

We have add three hosts to our system. But the data is not displayed as a graph. The performance gauge is available. This applies to the self written chacks as well as to the check_mk basic checks (i.e. filesystem).

There are only xml files under /opt/omd/sites/itops/var/pnp4nagios/perfdata// but no rrd-files.

The cmc log file is full of lines like this:
[4] [rrdcached] [rrdcached at “/omd/sites/itops/tmp/run/rrdcached.sock”] [log] -1 No such file: /opt/omd/sites/itops/var/pnp4nagios/perfdata//.rrd

Besides this rrdcached - Error we get errors like this:
[client 0] Error accessing RRD: opening
‘/opt/omd/sites/itops/var/pnp4nagios/perfdata//.rrd’: No such file or directory

Any help is appreciated.
Best regards
Matthias

Hi @MatthiasM, are you still using pnp4nagios on this site?

The data should be in ~/var/check_mk/rrd/ “nowadays”. Perhaps you could check the
corresponding rules (Configuration of RRD databases of services) and let us know how this is configured.

A good read about this topic: Performance data and graphing - Evaluating measured values in Checkmk quickly and easily
