Mount Point Monitoring

I am using the Nagios Core 4.4.3

We are monitoring the Mount Points using the Script: "./check_mount.sh"
https://exchange.nagios.org/directory/P ... is/details

One Mount Point is giving the Continuous Alerts: "WARNING - /backup is mounted several times! (2)"

There is no issue with the server.

Kindly suggest.

Same response as your other post:

You are going to need to run the command that the plugin runs manually when the issues is occurring. The command in the plugin is:

Code: Select all

MOUNTED=`mount | grep "$MOUNT" | grep -c "$FS "`            # execute the command to check the mount...
So as the nagios user run:

Code: Select all

mount
The output generated from this should help determine exactly what the issue is. Please paste the entire output here.

Here is the output of command that you shared:

XXX:/export/common/util on /util type nfs4 (rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,addr=xxx,clientaddr=xxx)
XXX:/backup on /backup type nfs (ro,addr=xxx)
XXX:/export/common/backup on /zfstst type nfs4 (rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,addr=xxx,clientaddr=xxx)

The issue is still going on.

There is no issue at the server end. Mount Point "/backup" is mounted only one time. But it is generating continuous alert "Mounted several times(2)."

So what is the output like 10 times in a row, or 20 times?. We need to nail down any sort of pattern.

I can't understand "what is the output like 10 times in a row, or 20 times?"

The problem is, this plugin is written in such a way, that it is just greps the output of mount for what you are passing, and if you pass /backup it is finding multiple matches
XXX:/backup on /backup type nfs (ro,addr=xxx)
XXX:/export/common/backup on /zfstst type nfs4 (rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,addr=xxx,clientaddr=xxx)
You probably could modify the plugin somehow to get around this, or contact the author
