waitmax is available
(it is is used to avoid hanging if the NFS server is not responding). The
probe is done by trying a stat -f (system call statfs(2)) on the mount point. If that lasts longer then 2 seconds, then the server is considered to be not responding. When you install the Linux agent manually, please do not forget to also install waitmax into /usr/bin. That file is shipped together with
the agent. When waitmax is missing, the agent will silently omit the
section nfsmounts.
If the NFS mount is "stale", then stat -f returns immediately but with
a size of -1. The check detects that and results in a warning state.
To configure usage levels and whether or not to output metrics use the WATO rule "Network filesystem - overall status and usage (e.g. NFS)"
Item
The mount point.
Discovery
One service is created for each NFS mounts. This is done by scanning {/proc/mounts}. The file {/etc/fstab} is irrelevant.
