Looks good.  Also this: http://www.xymonton.org/monitors:fs-test

This dynamically creates and removes "fs_<partition>" test dots for the
various filesystems (eg "fs_root", "fs_home", "fs_usr").  Long names are
converted to index numbers such as "fs_3" for the third filesystem listed.
 Each dot can be separately disabled or alerted as desired.  Typically runs
on the Xymon server and automatically gets what it needs by querying the
server via xymon calls, so no configuration required apart from tasks.cfg.

I am a user from bigbrother days.  In bigbrother I cloned/customized the
filesystem check script to allow me to have more than one disk column. I
usually had columns for disk_sys (OS) , disk_dba (dbase) and disk_app
(application). This allowed me to wake the other people (app/dba) when it
was their disk problem, a problem I was not going to touch anyway. In BB
the script ran on the remote/client machine. Now here in xymon I see disk
is part of the data pulled for each client and parsed on the server. I can
(and have) written a test to run on the client and send the status back up
to xymon - the old BB way. I was wondering if there was enough interest in
above functionality for me to make the effort to include it in the server
side parse code.


I have already looked into this and got a not-pretty-code version working
with this expended config in analysis

the FST (three chars) is appended to disk so below config will give extra
columns
      disk_dba disk_ard
in addition to just disk.   You can make as many extras as you want.

Just disk got everything not put anywhere else ... being paranoid about
losing newly added filesystems, there must be a 'everything else' column.

HOST=dbasserverone
        DISK %^/ip|du|vd|hq|sp|st|hd|iq|dc|id|ht|dt|hp|dd|dq... FST=dba
100 101
        DISK %^/[a-z][a-z][0-9][0-9][0-9] FST=dba 100 101
        DISK %^/dp... FST=dba 93 95
        DISK %^/redo..|arc.. FST=ard 90 95


In the screenshot the entries with disk_sys is actually the clients
running the old BB way.  "Everything else" is in disk_sys. For these  I
could hide the disk column, which is the column/monitor that the server is
generating. I just did not do the hide step.

This is a test setup, we are evaluating moving to Xymon. I found no
commercial product that can do multiple filesystem checks the way I want,
but I could make Xymon do it. Yeah open source!
