[Xymon] Custom script and COLUMN name

[Joel Carnat]

Hello,

I want to monitor CPU using SNMP/WMI/Perl SDK rather than deploying xymon-client on my boxes (on some of them, it is even not possible to compile/run xymon). So I went for writing custom scripts.

The first script I have is an SNMP Bash script that polls things like UCD-SNMP-MIB::ssCpuRawUser.0.

In my "server/ext/snmp_cpu.sh", I have setup BBHTAG="snmp_cpu" and COLUMN="snmp_cpu".

In the "etc/hobbit/hobbitserver.cfg", I have updated TEST2RDD adding ",snmp_cpu=ncv" and "NCV_snmp_cpu=”ssCpuRawUser0:GAUGE...".

In the "etc/hobbit/hobbitlaunch.cfg", I have added:
# Returns CPU statistics from SNMP
[snmp_cpu]
        ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd        CMD $BBHOME/ext/snmp_cpu.sh
        LOGFILE $BBSERVERLOGS/bb-retest.log        INTERVAL 5m

In the "etc/hobbit/hobbitgraph.cfg", I have added:
[snmp_cpu]
        TITLE CPU Statistics
        YAXIS Usage (%)
        DEF:user=snmp_cpu.rrd:ssCpuRawUser0:AVERAGE
(...)

Then restarted xymon-server.

Now, I have a "snmp_cpu" column with status updated and graphs generated.
But what I would like is to have the column named "cpu" and not "snmp_cpu".

If I simply set 'COLUMN="cpu"' in the snmp_cpu.sh script, then a new "cpu" column appears, show my script value but doesn't graph ; the reference to the graph is "service=la". Furthermore, the "snmp_cpu" column is still there.

What do I miss so that my "snmp_cpu" service appears as "cpu" in the main view.
The idea is to have a bunch of snmp_cpu, wmi_cpu scripts appearring as "cpu".

TIA,
	Jo
