How do I measure NFM-P performance?

Steps
 

Log into a main server, auxiliary server, or main database station as the root user.


Open a console window.


Enter the following to list the processes that have the highest CPU usage:

top ↵

Depending on your system configuration, approximately the top 20 processes are displayed. The top NFM-P process, by CPU usage, is typically the Java process.


Review the output; see the top man page for a description of the output fields.


Record the data for future performance comparison. Look for data that indicates excessive or continuously increasing CPU usage by the Java process.


Press Ctrl+C to stop the command.


Enter the following to list CPU resource usage information:

mpstat nn

where nn is the time, in seconds, between CPU polls; a value between 10 and 60 is recommended


Review the command output; see the mpstat man page for a description of the output fields.


Record the data for future performance comparison. Look for a difference in the output for a similar load on each station; a difference may indicate CPU performance degradation.


10 

Press Ctrl+C to stop the command.


11 

Enter the following to list disk performance information:

iostat -x n

where nn is the time, in seconds, during which you want to collect data; a starting value of 2 is recommended


12 

Review the output; see the iostat man page for a description of the output fields.


13 

Record the data for future performance comparison. Look for a difference in the output for a similar load on each station that may indicate disk performance degradation on a station.


14 

Press Ctrl+C to stop the command.


15 

Use an OS command to list network interface throughput and error statistics.


16 

Record the data for future performance comparison. Look for a difference in the output for a similar load on each station that may indicate network performance degradation.


17 

Close the console window.
