[Check_mk (english)] bug solaris NFS hanging results in statgrab hanging results in check_mk_agent hangin [suggested fix]

Hi,

I noticed a bug on Solaris servers. When a NFS mount point is stale it
hangs statgrab which therefore hangs the Check_MK agent and service.

This is obviously quite problematic.

The suggested fix I would like to recommend is change the agent from:

if statgrab > /tmp/statgrab.$$ 2>/dev/null

to:
if statgrab const. cpu. disk. general. load. mem. net. page. proc. swap. user. > /tmp/statgrab.$$ 2>/dev/null

The above basically does a statgrab on all except the file systems (fs.) as that results in a hang.

Could the above suggestion be included in future releases?

PS. I've managed to monitor NFS mount points on solaris by using MRPE with the check_nfs_health.sh nagios plugin.

Thanks,
Divan
