Hey,
I'm looking for some suggestions for implementing a service check on a
redundant host pair that access a shared resource.
Here's our setup:
We have N hosts that process (via delayed_job) a shared job queue
(mysql/redis). We have several checks that are host-specific (# of workers
on that

What you propose sounds acceptable. In the meantime I need to be careful
about reloading nagios :). Once I get it in that state, I have to disable
use_retained_scheduling_info and then do a full restart.

I've actually checked Nagios 4 now, and
I'm running Nagios 3.4.1 on RHEL6. I have an issue where I have a poller
(service check) that is running too often and I am not sure why. I have
service_check_timeout=180 because I had trouble with the poller running
long. Relevant settings for the service check:
check_period
Although some of those start times do seem close together, it's
important to know that the check_interval in Nagios is not necessarily a
hard number. Nagios is continually adjusting and recalculating the check
schedule, so if you need a check to run on a hard 5mn schedule, you
might be better
I understand that nagios dynamically adjusts service check times, but the
puzzling thing is that there is a check that runs every 5 minutes but then
an extra or two in between. And yes, the web interface shows the next
service check as 5 mins out and yet another runs before that time hits.

There isn't a second nagios instance. While I was watching the pollers
spawn, they all led back to the same master nagios instance.

yes you have to use a separate one for each site, how else would you be
able to use a separate check? Unless you expect the word Home on each

I've read the help docs, like I said I have a working installation checking
about 15 servers. I have a PING service that pings a host group. I can't
do that with this because I'm checking a different string on each site, so
i'm guessing it has to be separated out. Does this make sense?

You need to reread the docs, this is the most basic of questions.
http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#service
Hint: You are missing a service_description in the last block for one.
You should not have name in that last block either, you need host_name.
Read docs pls.

Yes I know what you've been doing, double or triple templating, and what
I am saying is that you do not need to template for every service.
Only template the common bits and put the unique bits in the service
definition block with the hostname.
You will need less blocks and have less
I wish I could, but I'm not a programmer and have limited experience with
Linux. I usually just manage Windows servers.
Thanks for your help though. I condensed the string check into one instead
of double/triple templating. Thanks.

As soon as one string is not found it goes critical.
You could always write a custom plugin to test your websites, or much
more easily a shell wrapper plugin to call

good question, it's sometimes more important to know what services are
