Subject storm ui, execute latency of multi-lang
Date Thu, 07 Apr 2016 08:03:26 GMT
Hi All,

I got several questions regarding storm ui and multi-lang processing.

1. Is there any APIs to get the storm statistics, e.g., execute latency,
capacity, as shown in the storm UI?
I would like to get those statistics automatically using a program and save
them to a file such that I don't need to monitor the UI all the time.
It would be great if you could provide an example.

2. How does storm compute the statistics for multi-lang bolt (I use c++)?
The statistics of my multi-lang bolt in UI is very strange.
For example, the expected execute latency of my multi-lang is about 2ms
(which can be computed inside c++), while the actual value shown in the UI
is only 0.002ms, which is extremely small...

Could someone give me some comments? Your thoughts will be much appreciated.
