Minor typo.
> Begin building controlling API to facilitate control of agents

> Key: MINIFI-339
> URL: https://issues.apache.org/jira/browse/MINIFI-339
> Project: Apache NiFi MiNiFi
> Issue Type: New Feature
> Components: C++
> Reporter: marco polo
> Assignee: marco polo
> Priority: Critical
> Labels: Durability, Reliability, Statistics
>
> Begin building the controlling API in MiNiFi C++. This API will evolve and
> likely have public and private elements. As development progresses we may
> want more capabilities.
> What I want to create as a straw man will be basic control and metrics
> gathering
> -- Start
> -- Stop
> -- Pause
> -- Gather metrics
> ** Throughput of of flow components
> ** Execution time ( run time minus sleep time )
> ** Memory consumption
> -- Drain repositories
> -- Switch repository types.
> Better employ update listener within this controlling API
