Hello all, I am curious to know if anybody out there is monitoring their Gluster systems in some way, and if so, how you've decided to go about it. I currently use Monit ( http://mmonit.com ) to do some basic checks : - is the glusterfs process in memory ? - is the glusterfs process a zombie ? - can a file be read on the gluster mount ? - can a file be written on the gluster mount ? One of the features of Monit is a simple connection test, whereby Monit will connect to the port of a given service, send a string, and then test the response. For example, one could connect to the SMTP service and issue a HELO, then check the response for validity. I would like very much to implement this feature, however i'm not sure that Gluster has any ? plaintext ? interactions of this sort. Is anyone aware of a way to implement this functionality ? The idea here would be to test whether the port is connectable /and/ that the process behind it is responding intelligently. I ask because a few weeks ago we had a problem where the glusterfs process was in memory, but wasn't actually accepting connections or interactions - a connection test would have found this problem immediately. Thank you, all ! -- Daniel Maher <dma+gluster AT witbe DOT net>
