Most companies have live and development systems.
Problems on live systems should be made known to the sysadmin immediately.
Problems on development systems should not cause an email to be sent immediately.
Nagios offers possibilities to have different alarming schemes for different hosts.
1. setup a new contact group
2. setup a new generic service
3. setup two hostgroups (one for live servers, one for development systems.)
4. setup services to monitor for each hostgroup. make use of the earlier defined service.
