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

Client module:

Table 1. Counter definitions . The table includes the counter name, key, description, granularity, type, level, overhead, and ID.
Name Key Description Granularity Type Level Overhead ID
ClientClusterUpdateCount wlmModule.client.numClientClusterUpdates The number of times initial or updated server cluster data is sent to a workload management enabled client from a server cluster member. Use this metric to determine how often cluster information is being propagated. Per client CountStatistic All Low 52
ClientResponseTime wlmModule.client.clientResponseTime The response time, in milliseconds, of IIOP requests being sent from a client. The response time indicates the amount of time that passes between when a request is sent from the client and a response is received from the server. Per client TimeStatistic All Medium 53
OutgoingIIOPRequestCount wlmModule.client.numOfOutgoingRequests The total number of outgoing IIOP requests sent from this client. Per client CountStatistic All Low 51

Server module:

Table 2. Counter definitions . The table includes the counter name, key, description, granularity, type, level, overhead, and ID.
Name Key Description Granularity Type Level Overhead ID
ConcurrentRequestCount wlmModule.server.numOfConcurrentRequests The number of remote IIOP requests currently being processed by this server Per server RangeStatistic Extended High 18
IIOPRequestCount wlmModule.server.numIncomingRequests The number of incoming IIOP requests that this server has received. Per server CountStatistic Extended Low 11
NoAffinityIIOPRequestCount wlmModule.server.numIncomingNonAffinityRequests The number of incoming IIOP requests that this server has received that have no affinity. These requests were sent to this server based on workload management selection policies that were decided in the workload management run time of the client. Per server CountStatistic All Low 14
NonWLMEnabledIIOPRequestCount wlmModule.server.numIncomingNonWLMObjectRequests The number of incoming IIOP requests that this server has received with no workload management enablement. Per server CountStatistic All Low 15
ServerClusterUpdateCount wlmModule.server.numServerClusterUpdates

The number of times that this server received new server cluster information.

This metric determines how often cluster information is being propagated.		 Per server CountStatistic All Low 16
ServerResponseTime wlmModule.server.serverResponseTime The amount of time, in milliseconds, that it takes for IIOP requests to be serviced by this server. The response time is the amount of time that passes between when the server receives the request and when it sends a response back to the client. Per server TimeStatistic Extended Medium 19
StrongAffinityIIOPRequestCount wlmModule.server.numIncomingStrongAffinityRequests The number of incoming IIOP requests that this server has received that have strong affinity. A strong affinity request is defined as a request that must be serviced by this application server because of a dependency that resides on the server. This request could not successfully be serviced on another member in the server cluster.

In Version 5.0 ND edition, transactional affinity is the only example of a strong affinity.

 Per server CountStatistic All Low 12
WLMClientsServicedCount wlmModule.server.numOfWLMClientsServiced The number of workload management-enabled clients that this server has serviced. Per server CountStatistic All Low 17
