Andrew Montalenti commented on STORM-324:
-----------------------------------------
I actually wrote a blog post about this very topic which is going to be
published soon on the Parse.ly blog. It's about Debugging Storm Topologies. I
am glad to take on this issue and include relevant information in Storm's
documentation.
> Require notes on internal of storm
> ----------------------------------
>
> Key: STORM-324
> URL: https://issues.apache.org/jira/browse/STORM-324
> Project: Apache Storm (Incubating)
> Issue Type: Documentation
> Affects Versions: 0.9.1-incubating
> Reporter: Srinath
> Priority: Minor
> Labels: documentation
>
> Require information about the internals of __tick and __metrics_tick.
> The only information about __tick tuples was from 0.8 release notes.
> This is more from a troubleshooting perspective since these tuples are
> generated by the system so frequently (can be seen when topology.debug is
> true)
> The kind of information that would help:
> 1. The mechanism of collecting metrics from each executor, spout or bolt
> 2. Looking at the tuple from debug logs, how to figure out which bolt these
> are intended to?
> 2. How does a bolt/spout/executor respond to it?
> etc.
