| Apache Ignite Performance Statistics Module |
| ------------------------------ |
| |
| Apache Ignite Performance Statistics module provides the tool to collect performance statistics from the cluster. |
| |
| Cluster nodes collect performance statistics to the files placed under 'Ignite_work_directory/perf_stat/'. |
| Performance statistics files are used to build the report offline. |
| |
| Building the Report |
| --------------------------- |
| To collect statistics in runtime and to build the performance report follow: |
| |
| 1) Start collecting performance statistics (use IgnitePerformanceStatisticsMBean JMX bean). |
| 2) Collect workload statistics. |
| 3) Stop collecting performance statistics (use IgnitePerformanceStatisticsMBean JMX bean). |
| 4) Collect performance statistics 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 |
| |
| 5) Run script |
| |
| performance-statistics/build-report.sh path_to_files |
| |
| to build the performance report. It will be 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. |
| |
| 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 |
