I'm looking at graphing our Linux Servers file systems for read and read-write access modes.

The result is either INTERGER 1 or 2 ( 1 means that the system is in read/write mode, and 2 means its in read only mode)

I've already setup the graph, but I need to chart whether or not I got back a result of 1, or 2, and send out an event if 2 is noted.

F -E --disable-rrdtool-tag --height=100 --width=500 --vertical-label= DEF:hrFSAccess-raw=rrdPath/hrFSAccess_hrFSAccess.rrd:ds0:AVERAGE DEF:hrFSAccess-raw-max=rrdPath/hrFSAccess_hrFSAccess.rrd:ds0:MAX CDEF: hrFSAccess = hrFSAccess-raw LINE1:hrFSAccess-raw#00cc00ff:hrFSAccess GPRINT:hrFSAccess-raw:LAST:cur\:%5.2lf%s GPRINT:hrFSAccess-raw:AVERAGE:avg\:%5.2lf%s GPRINT:hrFSAccess-raw-max:MAX:max\:%5.2lf%s\j

There is already a component template for FileSystem that collects usedBlocks data. I would start by copying the FileSystem (/Server) template to /Server/Linux. That way you have a separate copy to apply to your Linux servers and you preserve the original template (in case you do something nasty ;) ).
Add a new datasource, say readWriteMode, with the OID of 1.3.6.1.2.1.25.3.8.1.5 (you don't want your final .1 - that is the instance and will be automatically added by Zenoss for each filesystem).

What you really want is an event; I guess you are not particularly interested in graphing the 1 or 2 value Next create a threshold based on your new datasource. Make it a MaxMin and threshold on a max of 1 (ie the readWrite value). Customise the threshold event as you like - warning severity and /Perf/Filesystem event class might be good choices.

Cheers,
Jane

This FileSystem component template will automatically be inherited by all devices under /Server/Linux

I will give it a shot and let you know the outcome
