- For C(triggered) I(state) - Required. Short description of the problem that led to this trigger. This field (or a truncated version)
|

will be used when generating phone calls, SMS messages and alert emails. It will also appear on the incidents tables in the PagerDuty UI.
|
||||
The maximum length is 1024 characters.
|
||||
- For C(acknowledged) or C(resolved) I(state) - Text that will appear in the incident's log associated with this event.

incident_key:

description:
|

- Identifies the incident to which this I(state) should be applied.
|
||||
- For C(triggered) I(state) - If there's no open (i.e. unresolved) incident with this key, a new one will be created. If there's already an
|
||||
open incident with a matching key, this event will be appended to that incident's log. The event key provides an easy way to "de-dup"
|
||||
problem reports.
|
||||
- For C(acknowledged) or C(resolved) I(state) - This should be the incident_key you received back when the incident was first opened by a
|
||||
trigger event. Acknowledge events referencing resolved or nonexistent incidents will be discarded.
