[hobbit] Duration for one round of server side module

[T.J. Yang]

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 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.

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
