Hi all,<br><br>Here is some work related to Health monitoring. glfs-health.sh is a shell script to check the health of glusterfs.<br><a href="http://git.gluster.com/?p=users/avati/glfs-health.git;a=blob_plain;f=glfs-health.sh;hb=5bf3cb50452525f545018fa5f8eed06cb2fbbe7d">http://git.gluster.com/?p=users/avati/glfs-health.git;a=blob_plain;f=glfs-health.sh;hb=5bf3cb50452525f545018fa5f8eed06cb2fbbe7d</a><br>

</div>Checking if a connection to the GlusterFS TCP server port (6996 IIRC)<br>
is possible might be an indicator for working/failing - at least for<br>
setups that use TCP. I don't know if anything like that is possible<br>
for Infiniband-only setups.<br>
<br>
IIRC, Nagios can check if a port is open on a remote machine. That<br>
won't find something like disk/filesystem problems on the server, but<br>
it could report crashed GlusterFS server processes and machines that<br>
are not working at all.<br>
<br>
I know that this simple method won't provide a positive status (=it<br>
works) which would be preferable, but at least it can provide a<br>
negative status (=_something_ failed on _that_ machine) in some cases.<br>
<br>
@<a href="http://gluster.org" target="_blank">gluster.org</a>:<br>
IIRC, some time ago someone requested a syslog feature to debug<br>
problems with GlusterFS as root filesystem for a diskless cluster -<br>
are there any news on that?<br>
Having the clients report problems to a central logging server might<br>
be useful for monitoring.<br>
<br>
