Hi, I have a Hadoop installation, and I want to collect some basic OS level metrics like - cpu, memory, disk usage, and Hadoop metrics.
I have looked into Ganglia, but it requires installing agents on client machines, which is what I want to avoid. My queries: a) Is this a fair use case for using chukwa? e.g. polling client machines for CPU stats few times per minute? b) Is it possible to integrate data collected from chukwa collectors in a form readable by rrdtool kind of graphing tools on the server side? Thanks, Akshay
