service group concurrency limit?

[Páll Guðjón Sigurðsson]

We accomplish this at our end with the mod_gearman addon.

What we do is the following:

* Set all the services that need limiting together in one servicegroup
* Get mod_gearman up and running and have at least one mod_gearman_worker node (it may run on the nagios server or on another machine)
* Set max-workers on that mod_gearman_worker to the number of checks that may be run simultaneously
* mod_gearman will execute the checks instead of the nagios server, and number of checks will be limited


The only other way i know how would be to implement a locking (semaphore) somehow in the plugins themselves.

cheers,
Palli

Subject: [Nagios-users] service group concurrency limit?

I'm wondering if there is any way to limit the number of services that can be 
checked at one time based on service group.  I have some service checks that 
use a limited pool of resources (smaller than the number of services to check) 
and many others that have no such limitation.  So I need to set 
max_concurrent_checks in nagios.cfg to limit the number of concurrent checks. 
  Unfortunately, this is a global limit.  It would be nice if this sort of 
limit could be applied to a service group so the plugins don't have to manage 
concurrency.

Any ideas?   Thanks,

Paul Dubuc
