Predefined views
The Recent Log Manager Performance workspace includes the following predefined views:
- Recent Log Manager Performance The Log Manager Performance view summarizes log manager performance activity for all your z/OS queue managers. It provides statistics collected over several sampling intervals, displayed in descending order of date and time, which you can use to view trends in the data. The first row, Interval Summary, contains the averages of the attribute values listed in subsequent rows. From this list you can select a queue manager whose log manager performance history you want to review. This log can be used to back out messages in an incomplete logical unit of work or to recover messages after queue manager or system failure. For best performance, you should eliminate contention for DASD log files, provide sufficient buffer and log file capacity, and maintain correct log buffer thresholds.
- Reads/Writes This view displays, as a bar chart, the number of times the log is read from or written to per minute. It provides statistics collected over several sampling intervals, which you can use to view trends in the data.
