Running the Nytro Profiler On Windows : Running the Nytro Profiler in the Automatic Mode

Running the Nytro Profiler in the Automatic Mode

*

To profile the I/Os traces on the disk, for example, Disk0, type this command at the command prompt:

NytroProfiler_<64> -D disk0 -CFG san -SZ 200 -O trace_out

The Nytro Profiler runs until you press Ctrl+C on the keyboard. A trace_out.qt output file is generated.

*

To profile I/Os on a disk, for example, Disk0, for a specified run time, type this command at the command prompt:NytroProfiler_<64> -D disk0 -CFG san -SZ 200 -W 10 -O trace_out

A trace_out.qt output file is generated after the Nytro Profiler runs for 10 seconds.

*

To set a start time for the trace collection on a disk, for example, Disk0, type this command at the command prompt:

NytroProfiler_<64> -D disk0 -CFG das -SZ 200 -S 20 -O trace_out

Run the preceding command to start profiling after 20 minutes. To stop profiling, press Ctrl+C on the keyboard. A trace_out.qt file is generated.

*

To use both the -S and -W options together, type this command at the command prompt:NytroProfiler_<64> -D disk0 -CFG das -SZ 200 -W 10 -S 20 -O trace_out

To set the profiling to start after 20 minutes, run the preceding command with the -S 20 option and to set the Nytro Profiler to last only for 10 seconds, include the -W 10 option. A trace_out.qt output file is generated.

*

To profile I/Os on multiple disks simultaneously (for example, Disk0, Disk1, and Disk5):

NytroProfiler_64.exe -D Disk0:Disk1:Disk5 -CFG das -SZ 200:400:500 -O trace_out

The Nytro Profiler runs until you press Ctrl+C on the keyboard. A trace_out.qt output file is generated.

NOTE  Do not use space between multiple disks for -d option.

NOTE  The.qt extension is added to the output file specified, for example, the -o trace file generates a trace.qt file.
