Subject [jira] Reopened: (CHUKWA-419) Replace system metrics collection with sigar
Date Mon, 06 Sep 2010 22:21:32 GMT


Eric Yang reopened CHUKWA-419:

Sigar has switched from GPL license to Apache License 2.0 for Sigar 1.6.4+.  The website has
not made the announcement, but SVN license has been updated for a while.  Hence, it's worth
while to revisit this issue.

> Instead of having multiple java vm to execute unix commands to collect system metrics
(CPU utilization, network, memory, disk), it's more efficient to collect the metrics through
JNI interface.  SIGAR is a good replacement for Chukwa's input tools.  All licenses considered,
it's the next best option than reinvent the wheel.
