| Setting | Description
|--- |---
-| profiler.workers | The number of worker processes
to create for the topology.
-| profiler.executors | The number of executors to spawn
per component.
-| profiler.input.topic | The name of the Kafka topic from
which to consume data.
-| profiler.output.topic | The name of the Kafka topic to
which profile data is written. Only used with profiles that use the [`triage`
result field](#result).
-| profiler.period.duration | The duration of each profile
period. This value should be defined along with
`profiler.period.duration.units`.
-| profiler.period.duration.units | The units used to specify the
`profiler.period.duration`.
-| profiler.ttl | If a message has not been
applied to a Profile in this period of time, the Profile will be forgotten and
its resources will be cleaned up. This value should be defined along with
`profiler.ttl.units`.
-| profiler.ttl.units | The units used to specify the
`profiler.ttl`.
-| profiler.hbase.salt.divisor | A salt is prepended to the row
key to help prevent hotspotting. This constant is used to generate the salt.
Ideally, this constant should be roughly equal to the number of nodes in the
Hbase cluster.
-| profiler.hbase.table | The name of the HBase table that
profiles are written to.
-| profiler.hbase.column.family | The column family used to store
profiles.
-| profiler.hbase.batch | The number of puts that are
written in a single batch.
-| profiler.hbase.flush.interval.seconds | The maximum number of seconds
between batch writes to HBase.

> Improve Docs of `profiler.period.duration`
> -------------------------------------------
>
> Key: METRON-1050
> URL: https://issues.apache.org/jira/browse/METRON-1050
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.4.0
> Reporter: Nick Allen
> Assignee: Nick Allen
> Fix For: 0.4.1
>
>
> It is a common mistake for new user's of the Profiler, to alter the
> Profiler's `profiler.period.duration` property, but not alter the
> corresponding `profiler.client.period.duration` property. The new user is
> then unable to read the profile data as they would expect.
> More should be done, but this JIRA focuses on improving the documentation
> around this common error experienced by new users.
