http checks for multiple domains in the same server
We have a web server that has 7 web sites running, and about 100 domains. Most of the domains are in the same web site. Currently I have listed the most of the important sites, and I am trying to also get dnsreg (more on that later). What I would like to do, is run http check on these sites once a day, and not every day. Is it possible? Without changing the default http setting? (the top critical sites I want to check on default schedule)
While I am on the domain topic, I recently moved the server from hobbit to xymon, but the package deleted most of the hobbit folders automatically and I don't remember exactly which folders I had to put the dnsreg check. I though it was a server/ext but it is possible it is %XYMONHOME/client/ext?

The dnsreg script runs server-side, so should go into server/ext/.
The answer to most "can I..." questions is "yes, it's open source". ;-) Seriously though, you can certainly do an HTTP check daily if you like, from an ext script, and setting the lifetime on your status messages to 24 hours so as to prevent purples after 5 minutes. Something like this, listed in tasks.cfg (or tasks.d/somefile.cfg) to run every day or whatever you need:
#!/bin/sh
LIFETIME=24h
SITES="http://www.moo.com/this/that https://www.example.net/ ..."
FAILSITES=""; OKSITES=""
for SITE IN $SITES; do
wget $SITE && OKSITES="$OKSITES $SITE" || FAILSITES="$FAILSITES $SITE"
done
if [ "$FAILSITES" ]; then
$XYMON status+24h "$HOSTNAME.webchecks red date - failed one or more
web checks
These sites FAILED: $FAILSITES
These sites OK: $OKSITES"
else
$XYMON status+$LIFETIME "$HOSTNAME.webchecks green date - all web
checks OK
Sites tested: $OKSITES"
fi
This lumps all tests into one status - adjust the "webchecks" hostname accordingly if you want.
If you need to do per-site timing to go into RRD, it's a bit more complicated but doable using the NCV technique.
If you're asking if you can do this kind of thing with the built-in net checks, then I would think it's possible somehow, but you'd need to do something a bit more fancy. I'm thinking that you'd need to setup an alternative instance of xymonnet using "--test-untagged" and "--validity" flags and the XYMONNETWORK variable, and tagging hosts.cfg entries with NET:location. See the man page for xymonnet for more on this.

For the dnsreg..that is what I thought, and it is where I have it. I also have /etc/xymon/xymonserver.d Which does [dnsreg] #DISABLED ENVFILE /etc/xymon/xymonserver.cfg CMD /usr/lib/xymon/server/ext/dnsreg LOGFILE /var/log/xymon/xymonlaunch.log INTERVAL 1440m
This is to launch the dnsreg, but I guess it is not launching it Just in case I also added it to tasks.cfg
For the http checks. I created a httoweb.cfg in tasks.d with the code, and I added the domains (20 at the moment). What I am wondering is:
Do I need to rename the domain check from the host file (only the http like http://somedomain.com)And, If I remove the http check, where will it report the status?
