How does the vmstat.rrd file get populated? 🔗 link

Hi all,

I have added 2 channel processes to my Xymon 4.3.3 instance, that reads data from the status and data channels
and writes that data to a file for integration with another product.  I have a Solaris 10 client running a standard build
no bottom-feeders and I have a vmstat.rrd file, but I'm not seeing the vmstat data off my 2 channel processors.

How does the standard Xymon client send the file $XYMONHOME/tmp/xymon_vmstat.hostname.12558 to the
server?  I'm using Henrik's simple shell script and the --processor option on the rrd channels

If I use the bottom feeder scripts, vmstat gets written to my output file.

It is pasted into the normal client-message file. See the end of the 
OS-specific "xymonclient-OS.sh" script.

Ok, I guess I presented the question wrong.
So if it's a standard client message shouldn't I see the RRD data if I'm listening in on both status and data channels on the server?  

I'm using the data from the rrd channels to feed into another product, but I'm not seeing vmstat from the standard client.
There's an RRD file and a graph on the trends page showing vmstat CPU utilization but I'm not capturing that data in my file.

I have a number of older clients that still use the bottom feeder script and I'm capturing that data.

You should.

hobbitd_client will get the client data, hobbitd_client.c's 
unix_vmstat_report() function pushes the vmstat data to the data channel as 
$host.vmstat.

If I run 'hobbitd_client --channel=data cat' I see:

Yes I understand, but that's the plain data I'm looking at the RRD data, but now I'm wondering if I can't
have the 2 channels trying to write to the same file.  My test yields this as I had to adjust to get the
RRD data.  The script rf.sh just does exec cat
..//bin/xymond_channel --channel=data  xymond_rrd --processor=./rf.sh | egrep -I hostname

So I can verify I'm getting the RRD data, but again I don't think I can write the data from 2 channels into 1 file,
At least that's what it's looking like.  I don't remember seeing ifstat data in the other application I'm sending
this data to.

I will post back with my results
Thanks all for being a sounding board
