Instances availability

This monitor is dedicated for surveillance of ABAP application servers (AS).
It will send an alarm if an AS cannot be reached, if it is not registered 
on the message server or if is has been restarted. 

Configuration hints

  • You need to define the expected AS in the surveillance table (Use autodetect) and set the appropriate levels of severity.
  • If an unexpected AS is found, the monitor will also generate an alarm.
  • Response time alert(s):
    • Use the multi-threshold syntax to set multiple threshold/severity associations: G2W:1 W2M:2 M2C:3 (Green To Warning, Warning To Major, etc…), expressed in second, an alarm of the corresponding severity will be sent if time eapsed from last query is over threshold. Set 0 in the field if unused

Atomic fields

Send metadata Send collected instance information as metadata
Response time alert The threshold for the elapsed time of query. You can use the multi threshold syntax (i.e. : G2W:30 W2M:45 M2C:50)
Query Time-out Maximum duration in seconds of waiting before a query times out and an alert is sent
Severity unexpected instance Severity of the alarm to send if an unexpected instance is found

Surveillance table

ParameterDescription
MandatoryIf checked, the instance must be registered and responding.
Instance nameThe expected instance : [HOST]_[SID]_[NUMBER] , * can be used for select ALL
Availibility severityThe severity of the alarm sent if the AS is not responding.
Restart SeverityThe severity of the alarm sent if the AS is restarted.
Auto clearIf checked, the alarm will be cleared as soon as the alarm condition is not met anymore.
Alarm tagThis field allows to add custom text within the alarm message. %MSG% variable will contain the actual generated message and can be used such as: “my_prefix %MSG% my_suffix”. By default, tag will be used as prefix.
AlarmEnable of alarm sending
MetricEnable for metric sending

Examples

MandatoryInstance nameAvailibility severityRestart SeverityAuto clearAlarm tag
truemysap_PRD_00CRITICALWARNINGtrue

Effect : Send a CRITICAL alarm if instance mysap_PRD_00 is not responding, and a WARNING if it is restarted.

Examples

MandatoryInstance nameAvailibility severityRestart SeverityAuto clearAlarm tag
falsemysap_PRD_01CRITICALDISABLEDtrue

Effect : Ignore the fact that the instance is not responding or registered, ignore if restarted. The purpose of this line is to declare expected instances, so the probe can detect *unexpected* instances
