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
