[jira] Created: (CHUKWA-79) Chukwa should use less memory to
collect SystemMetrics
Chukwa should use less memory to collect SystemMetrics
------------------------------------------------------
Key: CHUKWA-79
URL: https://issues.apache.org/jira/browse/CHUKWA-79
Project: Hadoop Chukwa
Issue Type: New Feature
Reporter: Jerome Boulon
Chukwa is using 1 daemon process per Exec command.
This should be reduced to one and we should investigate how to use 3rd party libraries to collect system metrics in a more efficient way.

Mac Yang commented on CHUKWA-79:
--------------------------------
Reported from a user,
I saw 6 java processes whose job are nothing but launching external
commands (sar, ps, netstat, iostat, df, top, iostat). Each process
takes 150mb virtual memory and 20MB residential memory. This is a
total of 120MB for doing very trivial things.

----------------------------------
We do also have the ExecAdaptor, that launches those processes from within the Chukwa agent.
