is there a way how to configure nagios to send only one notification when some percentage of members defined in a hostgroup is down?
To be more specific:
- I have 500 computers monitoring
- sometimes the connecting net is going down
- I need to know imediately that it is happening and I dont want to get 500 emails but only one
- I have defined a group with this 500 members
- I dont know how to make nagios to generate only one email if for example more then 30% of this members are down
Thank you for any advice.
