Data collection and preparation
The IMS system log data is processed by the BMC AMI Ops Monitor for IMS Offline program IMFLEDIT (see Log-Edit), which extracts the BMC AMI Ops Monitor for IMS Offline records and some data from IMS log records and stores the data in a detailed IMS resource utilization file (IRUF; see IMS-resource-utilization-files-IRUFs). The detailed IRUF contains one record for each transaction or program activity and one record for each logical terminal generated in IMS.
Information in an IRUF can be summarized (through the TASCOSTR program; see Summarized-IRUFs) for a time period, such as one day. Data is grouped into the following record types:
Group | Description |
|---|---|
Terminal record | Summarized information for each logical terminal within a customer/user category per summarization period |
Program record | Summarized information for each program within the summarization period (for example, one program accounting record per program per day) |
Transaction record | Summarized information for each transaction code within a customer/user category per summarization period (for example, one transaction accounting record per transaction code within a customer/user category) |
In addition to summarizing IRUF data, you can create a subset of an IRUF (an extracted IRUF) by using the PRSSELEC utility. For more information about PRSSELEC, see IRUF-utilities.
The Performance Reporter (see Performance-Reporter-overview) and the Transaction Accountant (see Transaction-Accountant-overview) use any form of an IRUF to analyze data and create reports.
