Is it possible to monitor Impala using Ganglia? There is no reference to it on the Impala documentation and all metrics from Hadoop can be monitored from it. Is there a way to connect the performance metrics generated by Impala on Ganglia?

It isn't off-the-shelf available TMBK. However you could try this Grafana solution, and if necessary, intergrate it into Ganglia. It'd also worth mentioning that impala's built-in web page has tons of metrics and a nice dynamic query plan SVG visualizer.

  • Thanks. I already have a solution using Ganglia and my goal is to show only one dashboard. Using Grafana then passing to Ganglia is not what I was hoping for. It seems that I'll have to parse the web ui itself anyway. – Ivan Nov 28 '17 at 13:26

    Yeah, that will do. Impala uses a forked version of mongoose (due to license issue). The related web code is quite straightforward. Good luck! – Amos Nov 28 '17 at 15:33
