Ari Rabkin commented on CHUKWA-419:
-----------------------------------
Sigar is GPLed, so we can't redistribute it. I'm not sure we can even legally
link against it. We probably COULD include a Sigar adaptor in contrib.
Note that the exec adaptor is now working well, so running unix commands
doesn't require launching JVMs.
> Replace system metrics collection with sigar

> Key: CHUKWA-419
> URL: https://issues.apache.org/jira/browse/CHUKWA-419
> Project: Hadoop Chukwa
> Issue Type: Improvement
> Components: data collection
> Environment: Redhat EL 5.3, Java 6
> Reporter: Eric Yang
> Assignee: Eric Yang
>
> 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.
