Workload Management counters

You can use the workload management counters that the Performance Monitoring Infrastructure (PMI) and Tivoli Performance Viewer (TPV) collect to monitor how efficiently your workload is managed.

Data counters for this category contain information for workload management.

Counter definitions

Name	Key	Description	Granularity	Type	Level	Overhead
Num IIOP requests	wlmModule.server.numIncomingRequests	The total number of incoming IIOP requests to an appserver	Per server	CountStatistic	Extended	Low
Num strong affinity IIOP requests	wlmModule.server.numIncomingStrongAffinityRequests	The number of incoming IIOP requests to an appserver that are based on a strong affinity. A strong affinity request is defined as a request that must be serviced by this appserver because of a dependency that resides on the server. This request could not successfully be serviced on another member in the server cluster. In V5.0 ND edition, transactional affinity is the only example of a strong affinity.	Per server	CountStatistic	All	Low
Num no affinity IIOP requests	wlmModule.server.numIncomingNonAffinityRequests	The number of incoming IIOP requests to an appserver based on no affinity. This request was sent to this server based on workload management selection policies that were decided in the Workload Management (WLM) run time of the client.	Per server	CountStatistic	All	Low
Num non-WLM enabled IIOP requests	wlmModule.server.numIncomingNonWLMObjectRequests	The number of incoming IIOP requests to an appserver that came from a client that does not have the WLM run time present or where the object reference on the client was flagged not to participate in workload management.	Per server	CountStatistic	All	Low
Num server cluster updates	wlmModule.server.numServerClusterUpdates	The number of times initial or updated server cluster data is sent to a server member from the deployment manager. This metric determines how often cluster information is being propagated.	Per server	CountStatistic	All	Low
Num of WLM clients serviced	wlmModule.server.numOfWLMClientsServiced	The number of WLM enabled clients serviced by this appserver.	Per server	CountStatistic	All	Low
Num concurrent requests	wlmModule.server.numOfConcurrentRequests	The number of remote IIOP requests currently being processed by this server	Per server	RangeStatistic	Extended	High
Server response time	wlmModule.server.serverResponseTime	The response time (in milliseconds) of IIOP requests being serviced by an appserver. The response time is calculated based on the time the request is received to the time when the reply is sent back out.	Per server	TimeStatistic	Extended	Medium
Num outgoing IIOP requests	wlmModule.client.numOfOutgoingRequests	The total number of outgoing IIOP requests being sent from a client to an appserver	Per WLM	CountStatistic	All	Low
Num server cluster updates	wlmModule.client.numClientClusterUpdates	The number of times initial or updated server cluster data is sent to a WLM enabled client from server cluster member. Use this metric to determine how often cluster information is being propagated.	Per WLM	CountStatistic	All	Low
Client response time	wlmModule.client.clientResponseTime	The response time (in milliseconds) of IIOP requests being sent from a client. The response time is calculated based on the time the request is sent from the client to the time the reply is received from the server.	Per WLM	TimeStatistic	All	Medium
