Additional tests from xymon server 🔗 link

Hi,

I'm trying to add a test to the xymon server. This one has to reside
server-side because not it does domain checks and not all domains have an
assigned IP. Also, connectivity is not a concern here. What I'm trying to
do is add some domain in a subpage and check for changes in their
nameserver IPs. I've written a perl script that does the job and it takes
the domain name as a parameter. In practice I'm trying to replicate what
xymonnet does with the various checks like dns, http, smtp, etc.

I would have something like this hosts.cfg:

page domainchecks <H3>Domain Checks<H3>
<some IP>  <the domain name>  # noconn <my_test_name>

I did scrip this to check all domains at once but, that's not a desired
behavior because I need to xymon to treat them separately and tell me for
each if something changed or not according to my script.

I setup a test task in tasks.cfg like this:

[Environment]
        ENVFILE /var/lib/xymon/server/etc/xymonserver.cfg
        NEEDS xymond
        CMD $XYMONSERVERROOT/server/ext/env.pl
        LOGFILE $XYMONSERVERLOGS/ext-env.log
        INTERVAL 5m

I've set it up for some hosts to no avail:

<some ip> <hostname>  # env

It only shows up for the xymon server, which leads me to think this is more
cumbersome than I first thought. Has anyone managed to do something like
this before?

All I know is that I like you. I have no taste, but I like you.

How is your script identifying the hosts in hosts.cfg that have the test
set? are you using the xymongrep utility within env.pl?

The stanza in tasks.cfg only kicks off the script (every 5 mins as you have
specified), it doesn't pass any data to it and doesn't run it for each
host, you have to go and grab the data and work out which hosts to check,
so use 'xymongrep env' to find all the hosts to check, then split and work
out each domain, check each domain and pass the data back to xymon using
the 'xymon status' command.

How are you passing the domain names to the Perl script?  I don't see
how it could find any other name except the one from the xymon server
itself.  Generally I have a script which runs and "greps"  the hosts.cfg
(old bb-hosts) file to find  entries which I want the script run against
and in that script call the actual script which performs the test, pass
the variables needed (hostname or IP address).

Hi

Thank you all for your replies. xymongrep is what I was looking for. 
Also, Buchan's script was very helpful.

I've managed to add the desired checks by adding a new task in 
$XYMONHOME/servers/etc/tasks.d/domain-checks.cfg like this:
[Domain]
         ENVFILE $XYMONSERVERROOT/server/etc/xymonserver.cfg
         NEEDS xymond
         CMD $XYMONSERVERROOT/server/ext/domain_check.pl
         LOGFILE $XYMONSERVERLOGS/ext-domain_check.log
         INTERVAL 5m

In $XYMONSERVERROOT/server/ext/domain_check.pl I used xymongrep to 
filter out only the hosts with the domain tag in hosts.cfg and sent the 
status for each of the hostnames I've found back to xymon.

I'm a bit suprised I couldn't find documentation for such endevours more 
easily.

Please find an example attached. If I were to write this script today, I might
rather use a perl module I have that handles the communication with hobbitd.
This one uses 'ol' as the service name, or tag that should be in the hosts.cfg
file. I haven't modified it to run in Xymon 4.3.x, the bbhostgrep, and
possibly $ENV{BB} and $ENV{BBDISP} may need to be changed ...

I would recommend against using 'env' as a test name though, as some tests
(e.g. Devmon templates) use 'env' for 'environmental monitoring', such as
temperature, humidity etc.

Regards,
Buchan

It's on the "Xymon Tips and Tricks" page from the Help menu in Xymon.
 Where would you have expected to see the documentation?

Face palm...

I went like crazy through the man pages. Especially tasks.cfg and xymonserver.cfg.
