I am interested in monitoring my multi-agent apache flume setup. I have enabled the inbuilt ganglia server which provides me the flume metrics through JSON data. Now I am interested in viewing these info in graphs/charts. TO achieve this I am using ganglia web ui, I have these questions - Do I have to install gmond and gmetad to achieve it, if not then how I will use the existing ganglia info with the ganglia web ui ?
Thanks in advance.
You'll need both, IMHO. Moreover, I think Flume can communicate directly to a gmond by appending some stuff in JAVA_OPTS, see hortonworks docs.
You'll need gmetad because it stores your data in RRD files, and the web UI query on it to display graphs.
Graphite can do the job too.
