>                 Key: STORM-324
>                 URL: https://issues.apache.org/jira/browse/STORM-324
>             Project: Apache Storm
>          Issue Type: Documentation
>          Components: documentation
>    Affects Versions: 0.9.1-incubating
>            Reporter: Srinath
>            Assignee: Andrew Montalenti
>            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.
