Cut down notifications from Nagios

Applications Infrastructure Monitoring
1

Hello,
I am currently monitoring about 40 hosts using NsClient. Each host has between 5-8 services running on each of them. I was trying to find a way to get less notifications because I'm currently getting about 200 a week. Is there anyway for if one service goes down on a host to make nagios do a check of all the services and just send one email saying which ones are down rather than sending 6 separate emails if there is a blip in internet connection. If anyone knows how to do this or has any other ideas on how to cut down the amount of emails but make sure I don't miss anything it would be really useful.
Thank you very much,
Jethro

The way we have done in our environment is use service dependencies with this we have reduced the alert count drastically you can go through nagios doc to configure it

Jethro,

You could look at using and configuring the check_multi plugin for Nagios.

I've tried to set up service dependencies but they don't seem to work. I still recieved all of the emails. Any ideas what I did wrong?

define servicedependency{
    dependent_service_description     Uptime
    host_name            3cx
    hostgroup_name            servers
    service_description        NSClient++ Version
    inherits_parent            [0/1]
    execution_failure_criteria    o,w,u,c,p,n
    notification_failure_criteria    o,w,u,c,p,n
       }

With check multi I'm not sure if it will help in my case as I only use check_nt.

Thanks for the help :slight_smile:

You can use the following
inherit parent is not required in your case .I have given an example

define servicedependency{
   hostgroup_name                 servers
   host_name                      3cx
   service_description            NSClient++ Version
   dependent_service_description  Disk - C:,Load Average,Memory Usage,Uptime
   execution_failure_criteria     w,c,u,p
   }

Please let me know this helps thanks sorry for replying late
