[Xymon] xymon-client: Exclude directory from being checked by client.

Thanks Norbet,

I'll take a look at that file and see what I can come up with.

As these df calls are located in the xymonclient-linux.sh (for your linux systems) on the client side, you have to add your FS to the EXCLUDES variable in this script, like
EXCLUDES="$EXCLUDES -x additional_fs_type_to_ignore"

But these excludes only work for FS types, not for mount points.
Of course you can throw away all the messages (simply add 2>/dev/null after the df calls), but if there is a stale mount or other reason that causes df to hang, this will not help.

Hi Jeremy, thank you for your response!

We're running RHEL and the xymon-client is using df for disk checks.

Recently Docker was installed and configured to use specific mount point for devicemapper (/app2/docker/devicemapper). Not sure if this is standard as it was configured by the developers.

Some issue is causing the client to hang when checking disk utilisation on this mount point. The issue could be with df itself but I thought excluding it from the check would be the simplest option.

Regards,

What is the platform and why does checking it cause a problem?

If you are Linux or Unix it may help to add a switch to the df command.

Hi guys,

Does anyone know how I can exclude a directory from being checked by xymon-client for disk checks?

This has to be done client side because it appears to be breaking the client itself. Configuring the server to ignore the check won't prevent the client from trying to run checks on this directory.
