Question concerning port monitoring

Personally, I think I'd put check scripts on another system and check the
server instances individually, with different report columns for each.  I
had that working really well at EDS, with over 2500 reports being generated
for around 400 different "systems".  The test system was also the Xymon
server, which was a 733MHz, single cpu DL380.  I used cron for scheduling,
mostly every 5 minutes, with some longer periods (e.g. ssl certs once per
day) and one test that ran every 30 seconds...  :)

Ah -- I see.  Then the ports column covers all of the listeners on that
host so port 5321 is down and it goes red.....  Okay that's a different
issue.  Will have to think about that for a bit.

Thanks,

By server, he means "server instance." If he stops one "server" (like an
instance of Tomcat or something), he would like it to be separated out
from other instances of same on the same machine.

I might be missing your question.  If I want to monitor certain ports for
host xyz and other ports for host abc I can tell the software to do this by
configuring the server side hobbit-clients.cfg (analysis.cfg in xymon).

 These tests could also be for the same ports on different hosts.  Make sure
that the changes appear above the DEFAULT stanza in the file.

For example:

HOST=fred
....
PORT LOCAL=%(:13782|:13722|:13724|:13783) STATE=LISTEN MIN=1 COLOR=yellow

TEXT=netbackup

....

HOST=jane
...
PORT LOCAL=%(:1372|:1322|:1372|:137) STATE=LISTEN MIN=1 COLOR=yellow

TEXT=splat

...

Greetings,

We have a server that is running 3 different processes.  In the
hobbit-clients.cfg file, I have some PORT checks that are making sure
they
are listening on the appropriate port.

The problem I have is if the DEV server is taken down for maintenance, I
can’t just disable the “ports” check, because that will disable the
monitors
for the PROD and TEST ports.

How can I go about splitting out the port checks for a server and being
able
to enable/disable/acknowledge separately?

Thanks,

Tom
