--------------------------------------
Summary: Fix cli monitor component's argument type
Key: STORM-3956
URL: https://issues.apache.org/jira/browse/STORM-3956
Project: Apache Storm
Issue Type: Bug
Affects Versions: 2.3.0
Reporter: Richard Zowalla
>From https://github.com/apache/storm/pull/3423
The `component` value is a string, not a number, see
[Monitor.java](https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/utils/Monitor.java#L156).
Attempting to use a number throws a stacktrace like such:
```
~/apache-storm-2.3.0/bin/storm monitor -m wordGenerator production-topology
topology component parallelism stream time-diff ms emitted
throughput (Kt/s)
Available components for production-topology :
------------------
__acker
wordGenerator
intermediateRanker
counter
finalRanker
------------------
Exception in thread "main" java.lang.IllegalArgumentException: component:
wordGeneratotor not found
