Performance Statistics Extension

Overview

Ignite provides a built-in tool for cluster profiling.

The extension provides utilities to create the report and print statistics from the collected files.

Building the Report

Ignite provides a tool to generate the report from the performance statistics files.

Follow these steps to build the performance report:

Stop collecting statistics and place files from all nodes under an empty directory. For example:

/path_to_files/
    ├── node-162c7147-fef8-4ea2-bd25-8653c41fc7fa.prf
    ├── node-7b8a7c5c-f3b7-46c3-90da-e66103c00001.prf
    └── node-faedc6c9-3542-4610-ae10-4ff7e0600000.prf

Run the script from the release package of the tool:

performance-statistics-tool/build-report.sh path_to_files

The performance report is created in the new directory under the performance statistics files: path_to_files/report_yyyy-MM-dd_HH-mm-ss/. Open report_yyyy-MM-dd_HH-mm-ss/index.html in the browser to see the report.

For more details run the help command:

performance-statistics-tool/build-report.sh --help

Performance Statistics Report Example

Print Statistics

Ignite provides a tool to print statistics to a console or to a file in JSON format.

Run the script from the release package of the tool to print statistics:

performance-statistics-tool/print-statistics.sh path_to_files

Note that path_to_files is a path to the performance statistics file or files directory.

The script provides the ability to filter operations by operation’s type, time, or cache. For more details run the help command:

performance-statistics-tool/print-statistics.sh --help
