If I want to log certain metrics (like latency and throughput), what would be the best way of doing that?

I have thought of using hooks, but I'm not sure whether that's a bad idea. When I run a topology with several workers, will an assigned hook be instantiated multiple times as well? I'm worried that this could screw up my metrics.

I've found this blog post by Patricio Echague helpful. It might give you some ideas too: http://blog.relateiq.com/monitoring-storm/

Hi,

We've added Storm monitoring to SPM - see https://twitter.com/sematext .  It will be out next week.

That looks really interesting. Will there be an example on the webpage of monitoring Storm? I'm looking forward to trying it out!

Hi, 

   There are few  screenshots of future "SPM for Storm" tool, there will also CG, Network, CPU, Memory and other metrics for Nimbus process.
   I hope we will have this monitoring tool after 20 Dec in public access, see http://www.sematext.com/spm/

Best Regards, Vladimir.
