View source for IPHA - Monitoring server status

{{AI}}
The [[Redundant Servers - ICX-AlphaCom|IP-HA system]] reports changes of the server state to the [[Event Handler]].

This article describes how to configure the Event Handler in order to report current server state to the [[System log]].

== Error reporting ==
At the change of state is either:
* Communication between the servers is lost or resumed
* A server changes state from Standby to Operational, or vice versa

the following strings will be reported to the System Log whenever there is a change of state. 

* One of the servers is operational, and the other server is in standby mode:
{{code|Primary Server is operational. Both servers are running. }}
{{code|Secondary Server is operational. Both servers are running. }}

* One of the servers is operational, and the other server is Out of Service:
{{code|Primary Server is operational. WARNING: No communication with the other server. }}
{{code|Secondary Server is operational. WARNING: No communication with the other server. }}

== Configuration ==
From AlphaPro, select '''Exchange & System''' > '''Events''', and '''Insert''' a new event with the following properties:

<br style="clear:both;" />

Copy/paste the action commands below into the event:

{{Code2|
 IF %op(%sev,><nowiki>=</nowiki>,230)
 IF %op(%sev,<<nowiki>=</nowiki>,232)
 !Primary Server is operational
 WUDD 1001 1
 IF %op(%syse(232) ,&, %syse(230))
 !Secondary Server is operational
 WUDD 1001 2
 ENDIF
 IF %op(%op(%syse(230),<nowiki>==</nowiki>,0) ,&, %op(%syse(232),<nowiki>==</nowiki>,0))
 !Secondary Server is operational

From AlphaPro, select '''Exchange & System''' > '''Events''', and '''Insert''' a second event with the following properties (note that the ID of the event Owner must be "1"):

 ENDIF
 IF %op(%udd(1002),<nowiki>=</nowiki>,1)

 ENDIF
 IF %op(%udd(1002),<nowiki>=</nowiki>,0)
 tmp 2 "WARNING: No communication with the other server."
