Filtering and Calculations

CA SRM reduces and summarizes TSM log data according to user specifications. Data reduction and post-processing are different for each object created from the TSM logs. The following list describes the differences:

• CA SRM filters the Extract and Result files at the time of collection according to user-defined patterns.
• CA SRM generates attentions according to user-defined conditions that CA SRM tests at the time of data collection. Conditions generally involve counting the number of occurrences of given messages and comparing the result with a test value.
• CA SRM identifies severity levels during data collection by comparing user‑assigned severity values against individual messages. You can further tabulate and use the results to test conditions.
• CA SRM subjects the accumulated summary data of the various TSM sessions (the session data) to extensive post-processing and statistical analysis. The periodic TSM data collection service scans the session data, organizes it by TSM nodes, and totals and averages session statistics by node. CA SRM then adds this calculated information to the TSM node object. Similarly, the service totals and averages the node statistics by server. CA SRM adds this calculated information to the TSM server object.
