Subject [jira] Resolved: (CHUKWA-419) Replace system metrics collection with sigar
Date Sun, 26 Sep 2010 22:33:34 GMT


Eric Yang resolved CHUKWA-419.

    Fix Version/s: 0.5.0
       Resolution: Fixed

The patch works.  I flagged it as draft due to lack of automated method to download sigar
1.6.5 from maven repository.  I decided to bundle Sigar 1.6.5 with license.txt as part of
our library source code instead of waiting for Sigar team to publish 1.6.5 binary to maven.
 I tested on MacOSX only, but it should work with all major platforms.  I just committed this.

> 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.
