Microsoft GCToolKit

GCToolKit is a set of libraries for analyzing Java garbage collection (GC) log files. The toolkit parses GC log files into discrete events and provides an API for aggregating data from those events. This allows the user to create arbitrary and complex analyses of the state of managed memory in the Java Virtual Machine (JVM) represented by the garbage collection log.

GCToolKit build with Maven


NOTE

The gctoolkit build relies on test data which is archived in GitHub Packages. This requires you to authenticate to GitHub packages with a personal access token (PAT) to build and test.

If your organization uses Single Sign-On (SSO), also follow the directions under Authorizing a personal access token for use with SAML single sign-on.

You must also add github as a server in your ~/.m2/settings.xml file. Replace USERNAME with your GitHub user name and TOKEN with your PAT.

    <server>
      <id>github</id>
      <username>USERNAME</username>
      <password>TOKEN</password>
    </server>
