Hi All,
I was trying to understand from this example below. Can someone please explain me(considering newbie) this simple example on it's flow, the stages and the actions/events etc...
Why the rows form 2-5 says State change = Yes consecutively ?
This is from the bottommost example in this link (in case the below pasted one is unclear)-
http://nagios.sourceforge.net/docs/3_0/statetypes.html
Example
Here's an example of how state types are determined, when state changes occur, and when event handlers and notifications are sent out. The table below shows consecutive checks of a service over time. The service has a max_check_attempts value of 3.
Time Check # State State Type State Change Notes
0 1 OK HARD No Initial state of the service
1 1 CRITICAL SOFT Yes First detection of a non-OK state. Event handlers execute.
2 2 WARNING SOFT Yes Service continues to be in a non-OK state. Event handlers execute.
3 3 CRITICAL HARD Yes Max check attempts has been reached, so service goes into a HARD state. Event handlers execute and a problem notification is sent out. Check # is reset to 1 immediately after this happens.
4 1 WARNING HARD Yes Service changes to a HARD WARNING state. Event handlers execute and a problem notification is sent out.
5 1 WARNING HARD No Service stabilizes in a HARD problem state. Depending on what the notification interval for the service is, another notification might be sent out.
6 1 OK HARD Yes Service experiences a HARD recovery. Event handlers execute and a recovery notification is sent out.
7 1 OK HARD No Service is still OK.
8 1 UNKNOWN SOFT Yes Service is detected as changing to a SOFT non-OK state. Event handlers execute.
9 2 OK SOFT Yes Service experiences a SOFT recovery. Event handlers execute, but notification are not sent, as this wasn't a "real" problem. State type is set HARD and check # is reset to 1 immediately after this happens.
10 1 OK HARD No Service stabilizes in an OK state.
Thanks in advance,
sena
