Hi - can someone confirm if the following scenario regards service escalations is correct? I have a service check that simply performs a TCP check, if it fails it will email the contact with a defined notification_interval of 5mins. I also have a serviceescalation defined as follows: define serviceescalation{ hostgroup_name desktopsnahisservers service_description DESKTOP SNA SERVICE TCP 4097 first_notification 3 last_notification 0 notification_interval 5 contacts me_at_home } If the TCP check continues to fail the service escalation contact starts to get alerts but the actual contact for the defined service doesn't. Is this behaviour to be expected? As a solution I've simply added the defined service contact to also be a contact under the serviceescalation section as well. I'm running Nagios 3.4.3. Thanks - Julian.
