You can start server instrumentation from an administrative
command line or from an administrative client. After you stop server
instrumentation, you can use the results to determine where performance
problems are occurring.
About this task
You must have system privilege to start or stop server instrumentation.
Procedure
Complete the following steps to use server instrumentation:
- Issue the INSTRUMENTATION BEGIN command to start
instrumentation from the administrative client:
dsmadmc -credentialsfile=secretpwdfile instrumentation begin
The id that is specified in the credentials file must be an IBM
Storage Protect administrator ID that has system privilege.
- Start an operation for which you want to analyze performance.
- Issue the INSTRUMENTATION END command
to stop server instrumentation. Specify an output file for the data.
If you do not specify an output file, data is written only to the
screen. If you issue any remote commands from an administrative client
and redirect the output to a file, that file is saved to the administrative
client.
The following command can be issued from the administrative
client:
dsmadmc -credentialsfile=secretpwdfile instrumentation end > filename
