About the project

Watson is a JVM thread dump and CPU usage analyzer.

It combines the best features of other popular Java TDAs and optionally hides a lot of noise, like idle Tomcat threads waiting for work.

Gathering thread dumps

To fully leverage Watson, you should capture Java thread dump and top outputs.

The easiest way to do this is to generate a support zip and load files from the jfr-bundle/atst_in_product_diagnostic_<timestamp>/threaddumps directory.

You can also manually collect the data (also for non-Atlassian applications) by using Atlassian Support scripts.

Development

You only need yarn installed on your machine.

Available scripts

In the root project directory, you can run:

yarn install

Installs the required packages. Must be done prior to yarn start

yarn start

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits. You will also see any lint errors in the console.

yarn lint

Runs the linter to check if coding rules are followed.

yarn test

Launches the test runner in the interactive watch mode.

yarn deploy

Deploys the app to GitHub pages. Requires commit rights to the gh-pages branch.
