 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.

*Subject:* [hobbit] Duration for one round of server side module


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
