Procedure 1. To perform a diagnostic action: v Open a workspace view that shows real-time data and compare it with the unexpected data. v To understand how data is aggregated for various data types, see Tivoli Management Services Warehouse and Reporting (http:// www.redbooks.ibm.com/abstracts/sg247290.html). This IBM Redbooks publication describes aggregation methods used by the Summarization and Pruning Agent. 2. To perform a corrective action: v Review the documentation for the monitoring agents that are generating the unexpected values. This clarifies the expected types of values for the attributes in question. Resolving persistent data store for z/OS problems If you encounter a problem with the configuration of the persistent data store on the Tivoli Enterprise Monitoring Server, you can check the RKPDLOG output to verify the configuration. About this task To resolve persistent data store for z/OS problems, you perform diagnostic and corrective actions. These actions include verifying that the data store is configured properly. Procedure Diagnostic and corrective actions 1. Is historical data configured to be collected at the agent or the monitoring server? If the agent is configured in the address space of the monitoring server, then historical data can be collected only at the monitoring server. v If historical data is configured to be collected at the monitoring server, see step 2 below. v If historical data is configured to be collected at the agent, see step 3 below. 2. To verify that the persistent data store is configured correctly, on the monitoring server, check the RKPDLOG output, for example: v 2008/07/28 08:45:41 KPDIFIL: Status of files assigned to group GENHIST: 2008/07/28 08:45:41 2008/07/28 08:45:41 &philev.RGENHIS3 Status = Active 2008/07/28 08:45:41 &philev.RGENHIS2 Status = Offline 2008/07/28 08:45:41 &philev.RGENHIS1 Status = Offline 2008/07/28 08:45:41 2008/07/28 08:45:41 KPDIFIL: End of group GENHIST status. 3. To verify that the persistent data store is configured correctly at the agent, check the RKPDLOG of the agent, for example: v If KM5AGENT (this agent runs on the monitoring server), check the RKPDLOG of the monitoring server: 2008/07/28 08:48:27 KPDIFIL: Status of files assigned to group PLEXDATA: 2008/07/28 08:48:27 2008/07/28 08:48:27 &philev.RKM5PLX3 Status = Active 2008/07/28 08:48:27 &philev.RKM5PLX2 Status = Empty 2008/07/28 08:48:27 &philev.RKM5PLX1 Status = Partially Full 2008/07/28 08:48:27 Chapter 3.
