3.4.9 Estimating the size of execution agent performance log files
This subsection explains how to estimate the size of execution agent performance log files.
Execution agent performance log files are binary-format log files that are output if the execution agent performance report output function is enabled. The data recorded in execution agent performance log files can be exported to CSV files by using the ajsagtreport command. For details about the execution agent performance report output function, see 5.3.2 Overview of the execution agent performance report output function in the JP1/Automatic Job Management System 3 Administration Guide.
Execution agent performance data is output to execution agent performance log files.
For the execution agent performance log files, the minimum period for which data is retained in execution agent performance log files can be specified by using the AJSAGTREPORTSTOREDAYPERIOD environment setting parameter.
The performance log data for the specified retention period is fully saved even when JP1/AJS3 is continuously operating. If JP1/AJS3 is not operating frequently, performance log data for a period longer than the specified period might be saved. For details about the AJSAGTREPORTSTOREDAYPERIOD setting parameter, see 20.3.2(24) AJSAGTREPORTSTOREDAYPERIOD in the JP1/Automatic Job Management System 3 Configuration Guide.
The maximum size of execution agent performance log files is determined by the number of defined execution agents and the value specified for the AJSAGTREPORTSTOREDAYPERIOD environment setting parameter. You can calculate the maximum size of execution agent performance log files by using the following formula:
The maximum size of execution agent performance log files (unit: kilobytes) =
374 x number-of-defined-execution-agents x value-of-AJSAGTREPORTSTOREDAYPERIOD-environment-setting-parameter (units: days)
- Example:
-
If the number of defined execution agents is 64 and the data in a performance log file is retained for at least 14 days, the maximum size of performance log files is as follows:
374 x 64 x 14 = 335,104 kilobytes
