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.
