[Learn about configurations >](https://juju.is/docs/juju/configuration#heading--application-configuration)

* channel\_capacity | string

  Default: 1000

  The maximum number of events stored in the channel.
* channel\_transaction\_capacity | string

  Default: 100

  The maximum number of events the channel will take from a source or
  give to a sink per transaction.
* dfs\_replication | int

  Default: 3

  The DFS replication value. The default (3) is the same default as the
  Namenode charm, but it may be overriden for this application.
* protocol | string

  Default: avro

  Ingestion protocol for the agent source. Currently only 'avro' is supported.
* resources\_mirror | string

  URL from which to fetch resources (e.g., Flume binaries) instead of S3
* roll\_count | int

  Number of events written to file before it is rolled. A value of 0 (the
  default) means never roll based on number of events.
* roll\_interval | int

  Default: 300

  Number of seconds to wait before rolling the current file. Default
  will roll the file after 5 minutes. A value of 0 means never roll
  based on a time interval.
* roll\_size | string

  Default: 10000000

  File size to trigger roll, in bytes. Default will roll the file once
  it reaches 10 MB. A value of 0 means never roll based on file size.
* sink\_compression | string

  Compression codec for the agent sink. An empty value will write events
  to HDFS uncompressed. You may specify 'snappy' here to compress written
  events using the snappy codec.
* sink\_serializer | string

  Default: text

  Specify the serializer used when the sink writes to HDFS. Either
  'avro\_event' or 'text' are supported.
* source\_port | int

  Default: 4141

  Port on which the agent source is listening.
