-HICC, the visualization component, is "beta" quality. It's been used succesfully at multiple sites, but it's still brittle. Work is ongoing. Documentation is still sparse, and error reporting isn't always sufficiently clear. +

The demux pipeline has been cleaned up somewhat, and is now documented. See the programming guide for a discussion of how to customize demux for your purposes.

-Chukwa has not been extensively audited for security vulnerabilities. Do not run it except in trusted environments. Never run Chukwa as root: By default, the ExecAdaptor allows arbitrary remote execution. +

Requirements

-Chukwa relies on Java 1.6 -The back-end processing requires Hadoop 0.18+. -Collecting Hadoop logs and metrics requires Hadoop 0.20+. +

Chukwa has not been extensively audited for security vulnerabilities. Do not run it except in trusted environments. Never run Chukwa as root: By default, the ExecAdaptor allows arbitrary remote execution.

Important changes since last release

+ +
    +
  • The collection of shell scripts in /bin has been significantly pared down. For instance, instead of bin/agent, you should now say bin/chuka agent.
    • +
  • It is now possible to disable remote connections to the Chukwa agent. This makes Chukwa more suitable for use on a customer-facing deployment
    • . +
  • Chukwa now includes an adaptor for reading data via a UDP port, the UDPAdaptor. This should facilitate integration with syslog and similar legacy tools.
    • + +
  • +There have been a number of bug fixes and code cleanups since the last release; check the changelog and JIRA for details.

Known Limitations

  • HICC defaults to assuming data is UTC; if your machines run on local time, HICC graphs will not display properly until you change the HICC timezone. You can do this by clicking the small "gear" icon on the time selection tool.
