DS Performance Monitoring

From Tecniq

Monitor via Script

You can log a history of volume IOPs and throughput figures using the script feature within the Storage Manager Enterprise Management window. (This window lists all subsystems under management by the host.) Select the subsystem you wish to monitor and select "Tools -> Execute Script...". This should open a text box with a horizontal split. Enter the following in the top box;

on error stop;
set performanceMonitor interval=10 iterations=2;
upload storageSubsystem file="c:\perffile.txt" content=performanceStats;

This will repeatedly execute the performance monitor command every interval in seconds, for the number of times highlighted by the iterations. Note that you cannot close the window during this recording, so if you're recording a long period the application will need to remain running.

The data is stored in a flat file defined in the command, and the output looks as follows;
