[jira] [Created] (STORM-324) Require notes on internal of storm

Srinath created STORM-324:
-----------------------------

             Summary: 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


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.
