I’ve started using the nfsiostat agent plugin on some servers where I want to know more about the servers’ NFS-client activity.
And when looking in Checkmk’s web-interface, I do see NFS stats numbers in a new monitoring item. However, the related RRDtool graphs are broken, see attached screenshot.
I have not succeeded finding anything interesting in log files on the server where Checkmk’s server-part is installed.
How do I troubleshoot further?
PS:
The error has been seen with the following server/agent version combinations:
Server: 1.6.0p14, agent: 1.6.0p9.
Server: 1.6.0p8, agent: 1.6.0p9.
Server: 1.6.0p7, agent: 1.6.0p13.
