MVS_CFStructToMVS_Requests_Crit

MVS_ CFStructToMVS_Requests_Crit monitors the number of requests that the coupling facility makes to a given z/OS system and raises a Critical alert when the coupling facility performance has deteriorated severely.

The formula is:

VALUE CF_Structure_to_MVS_System.Average_Queued_Request_Time GT 100 OR VALUE CF_Structure_to_MVS_System.Request_Rates *GT 1000

If this situation is raised, check the status of the coupling links and the performance data for the coupling facility machine or LPAR. A link may be down or a processor maybe offline or malfunctioning. If the coupling facility is in an LPAR with shared processors, the overall CPC may be fully loaded, thus causing the LPAR weights to come into effect. If more LPs are assigned to the CF than its share of total weight can support, try varying an LP offline.
