integration of foreign graphs

jc's pointer i didn't understand it .. :-(
perhaps do you mean the option --extra-script for xymond_rrd ?

Thanks a lot & cheers

Yep. It can be used to intercept the data rrd is about to send off to
rrdtool and send it to something else as well. I had a small script that
converted lines from (say) disk utilization to relevant OpenTSDB metrics.

Xymond_rrd also has an option for an "external processor", which you can
use to inject metrics data elsewhere as well. I was inserting directly
into an OpenTSDB instance for a while using that and it worked fine.

If you need to deal directly with the rrd's, then David's response has
you
covered nicely.

If you don't need to deal with the rrd's directly, i.e. you have images
already (png) or a UI for accessing the graphs (Cacti), then another
approach *might* be easier. YMMV, of course. We use Cacti for our
graphing
needs and incorporate those graph(s) into Xymon via an updated
"svcstatus.sh" cgi script. There is a config file that we have created
to
hold the "mapping" info:

~xymon/server/etc/cacti.cfg
host1.cpu:2345
host1.disk:745

host2.cpu:13
host2.disk:456
host2.disk:457
host2.disk:458
etc.
etc.

where, above, the host and service are clear and are mapped to the
local_graph_id in Cacti. The other side of the ":" could be anything
though, as you will see. Assuming you are using the xymon dynamic
status
page setup, when you go to a particular status page in xymon you can
see
the host and service in the URL as parameters passed to svcstatus.sh. I
have updated the svcstatus.sh to use the above config file to add a
link
into the displayed xymon page based on those parameters:

~xymon/cgi-bin/svcstatus.sh
#!/usr/bin/bash

# This is a wrapper for the Xymon svcstatus.cgi script

. /usr/xymon/server/etc/cgioptions.cfg

# Get HOST and SERVICE
export `echo $QUERY_STRING | sed -e "s/\&.*$//"`
export `echo $QUERY_STRING | sed -e "s/^[^\&]*\&//"`

for i in `cat /usr/xymon/server/etc/cacti.cfg | grep "$HOST\.$SERVICE"
|
awk -F: '{ print $2 }'`; do

   # Just appends multiple links/images/whatever to a temp file so you
can
get multiple images/graphs on the same page
   echo -n "<\/TD><\/TR><\/TABLE><TABLE><TR><TD align=center><a
href='http:\/\/our.cacti.host\/cacti\/graph.php?local_graph_id=$i\&rra_id=all'
target='_blank'><img
src='http:\/\/our.cacti.host\/cacti\/graph_image.php?local_graph_id=$i\&rra_id=1'
border=0><\/a>" >> /tmp/cactigraph.$$
done

# Get the temp file contents into a env variable for easy regexp use
below
if [ -r /tmp/cactigraph.$$ ] ; then
   CACTI=`cat /tmp/cactigraph.$$`
else
   CACTI=""
fi
rm -f /tmp/cactigraph.$$

# Insert the links in the output of the status page for display
if [ ! -z "$CACTI" ] ; then
   exec /usr/xymon/server/bin/svcstatus.cgi $CGI_SVC_OPTS | sed -e
"s/<PRE>/$CACTI<PRE>/"
else
   exec /usr/xymon/server/bin/svcstatus.cgi $CGI_SVC_OPTS
fi


You can really make that link anything you need; for us it is a call to
cacti using the local_graph_id but for an existing png you could make
the
other side of the ":" in the config file the png filename and just use
a
straight <img> tag. Hope this helps.
