The recording interval (in seconds) should be a multiple of 60. If the recording type is local binary recording, then the user has an option to enable the IBM Workload Estimator (WLE) report generation in the SMIT screen. The WLE report is generated only on Sundays at 00:45 a.m. and requires local binary recording to always be enabled for consistent data in the report. The data in the weekly report is correct only if the local recordings are always enabled.

The generated WLE report is stored in the /etc/perf/<hostname>_aixwle_weekly.xml file. For example, if the hostname is ptoolsl1, the weekly report is written to the /etc/perf/ptoolsl1_aixwle_weekly.xml file.

If the filesystem threshold is enabled, the topasrec command pauses the recording when the file system used space crosses the maximum percentage of the specified filesystem threshold. It will then write an error log entry. The topasrec command resumes the recording when the file system used space goes back to less than the minimum percentage of the file system threshold.
