Verbose logging
By default, the Cluster Test Tool uses verbose logging to provide a wealth of information about the results of cluster testing. You can customize the type of information that the tool gathers and stores in the Cluster Test Tool log file.
Note: The Cluster Snapshot utility does not include the Cluster Test
Tool log file because this file is specific to PowerHA® SystemMirror® cluster testing at a
specific point in time - not an indication of ongoing cluster status.
With verbose logging enabled, the Cluster Test Tool:
- Provides detailed information for each test run
- Runs the following utilities on the control node between the processing
of one test and the next test in the list:
Utility Type of Information Collected clRGinfo The location and status of resource groups errpt Errors stored in the system error log file - Processes each line in the following files to identify additional information
to be included in the Cluster Test Tool log file. The utilities included are
run on each node in the cluster after a test finishes running.
File Type of Information Specified cl_testtool_log_cmds A list of utilities to be run to collect additional status information See Customizing the types of information to collect.
cl_testtool_search_strings Text strings that may be in the hacmp.out file. The Cluster Test Tool searches for these strings and inserts any lines that match into the Cluster Test Tool log file. See Adding data from hacmp.out to the cluster test tool log file.
If you want to gather only basic information about the results of cluster testing, you can disable verbose logging for the tool. For information about disabling verbose logging for the Cluster Test Tool, see Running automated tests or Setting up custom cluster testing.
