Using the Nytro Predictor Software Tool : Using the Nytro Profiler Feature

Using the Nytro Profiler Feature

You can use the Nytro Profiler feature on the Windows platform and Linux platform. You can run the Nytro Profiler in either the Manual mode or the Automatic mode.

*

Manual mode

*

Step 1: Collect the I/O traces of interested HDDs using either blktrace or Xperf on a Linux or Windows machine, respectively.

*

Step 2: Run the Nytro Profiler tool with the trace file collected from the previous step as input.

The Nytro Profiler generates a file with.qt extension, which is used by the Nytro Predictor tool for further analysis.

NOTE  Step 1 and Step 2 are independent. That is, you can perform Step 1 on the target machine (see the Nytro Profiler topic, for information about target machine) and Step 2 on any machine.

*

Automatic mode

*

Step 1: Run the Nytro Profiler on the interested HDDs. The tool seamlessly collects the I/O traces and also generates the .qt file for further analysis by the Nytro Predictor tool.

NOTE  The examples provided in this chapter are for 64-bit machines. Use ./NytroProfiler_32 on Linux or NytroProfiler.exe on Windows for 32-bit machines.

NOTE  By default, the qpcp.log file is created when you run the Nytro Profiler.
