Thanks for the info, I documented the differences of these two approaches.

Hi Asif
There are a few questions need to be addressed for non-home deployment.
1. Do we want to have xymon clients to query Sun's patch database file ?
The answer should be No for a site have big xymon client installations.
2. the pca xymon client module should query internal solaris patch database server(on xymon server).
3. the pca xymon server side EXT module should in sync with Sun's patch database server and download the zip files for internal installation.
4. pca rely on wget and wget rely on other software also, be prepared to deal with pca xymon module for solaris 2.6 and above that doesn't come with wget.
I discussed w/ pca community and server side module works better
Here is the thread.
http://www.mail-archive.com/user-300bc63e296e@xymon.invalid/msg00939.html
Most of the servers are between sol 8 and sol 10 but that is not a problem since I am doing it
on the server side and my hobbit server is sol 9
I updated the hobbitclient-sunos.sh file and pushed using clientupdate method to all the clients.
only the following lines needed to add to the hobbitclient-sunos.sh. That was enough data to generate the pca report
echo "[showrev]"
showrev -p
echo "[pkginfo]"
pkginfo -x
right below [ps] section
Also whenever new version pca comes I just need to update the pca on hobbit server to get my patch report
I don't quite understand why you design pca work as server side module
For me, I did it as a client side module and create another column (pca) for each xymon client.
Here is an example of what it looks like so far
http://xymon.dlinkddns.com/hobbit-cgi/bb-hostsvc.sh?HOST=netinstall.test.net&SERVICE=pca
P.S. I interacted with pca author but failed to convince him we (xymon community) can have a "-M" option to send out xymon needed html format.
You use the `-L ' switch to get html report.

I implemented a server side perl script using this http://xymonton.trantor.org/doku.php/tutorials:ssmodule as the template.
I like to run it only once daily, so I put status+1d for the bb command.
But I need help to find out how long it takes for the script to complete for my ~300 hosts.
Currently I have it setup just like the setup in the above url, like the following.
[pca]
ENVFILE /export/home/hobbit/server/etc/hobbitserver.cfg
NEEDS hobbitd
CMD hobbitd_channel --channel=client --log=$BBSERVERLOGS/pca.log $BBHOME
/ext/pca.pl
And it is taking tons of resources since it receives all the patch/pkg info from 300 servers through client channel and generate a patch report using the tool pca (http://www.par.univie.ac.at/solaris/pca/) for each host. It allows us
to find out the patch status for all solaris boxes
Here is an snippet of the top processes sorted by RSS
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP 8687 hobbit 2248M 581M run 39 0 0:02:31 1.1% hobbitd_channel/1
8648 hobbit 58M 56M run 39 0 0:07:42 2.5% hobbitd/1
10223 hobbit 21M 20M run 20 0 0:00:03 15% perl5.8.5/1
7115 devmon 11M 11M sleep 59 0 0:00:44 1.5% devmon/1
8689 hobbit 8816K 6968K sleep 59 0 0:07:52 2.7% pca.pl/1
If I can find out how long it takes to run I can then add an INTERVAL accordingly. I do not need to process the client data more than once a day
