+== cloudfoundry module
+
+experimental[]
+
+This is the cloudfoundry module.
+
+The Cloud Foundry module connects to Cloud Foundry loggregator to gather container, counter, and value metrics into a common data platform where it can be used for analysis, visualization, and alerting.
+
+
+The cloudfoundry module metrics are numerical values that describe some aspect of a system at a particular point in time. They are collected when pushed from the loggregator and are identified with a timestamp, a name, a value, and one or more defining labels.
+
+The cloudfoundry module mericsets are `container`, `counter` and `value`.
+
+[float]
+=== Module-specific configuration notes
+
+All metrics come from the Cloud Foundry loggregator API. The loggregator API authenticates through the Cloud Foundry UAA API.
+This requires that a new client be added to UAA with the correct permissions. This can be done using the `uaac` client.
+
+[source,bash]
+----
+$ export CLOUDFOUNDRY_CLIENT_ID=metricbeat
+$ export CLOUDFOUNDRY_CLIENT_SECRET=yoursecret
+$ uaac client add $CLOUDFOUNDRY_CLIENT_ID --name $CLOUDFOUNDRY_CLIENT_ID --secret $CLOUDFOUNDRY_CLIENT_SECRET --authorized_grant_types client_credentials,refresh_token --authorities doppler.firehose,cloud_controller.admin_read_only
+----
+
+Then configuration of the module needs to contain the created `client_id` and `client_secret`.
+
+[source,yaml]
+----
+- module: cloudfoundry
+ api_address: https://api.dev.cfdev.sh
+ client_id: "${CLOUDFOUNDRY_CLIENT_ID}"
+ client_secret: "${CLOUDFOUNDRY_CLIENT_SECRET}"
+ ssl:
+ verification_mode: none
+----
+
+
+[float]
+== Metricsets
+
+[float]
+=== `container`
+The container metricset of Cloud Foundry module allows you to collect container metrics that the
+loggregator sends to metricbeat.
+
+[float]
+=== `counter`
+The counter metricset of Cloud Foundry module allows you to collect counter metrics that the
+loggregator sends to metricbeat.
+
+[float]
+=== `value`
+The value metricset of Cloud Foundry module allows you to collect value metrics that the
+loggregator sends to metricbeat.
+
+
+[float]
+== Configuration options
+
+The `cloudfoundry` input supports the following configuration options.
+
+[float]
+=== `api_address`
+
+The URL of the Cloud Foundry API. Optional. Default: "http://api.bosh-lite.com".
+
+[float]
+=== `doppler_address`
+
+The URL of the Cloud Foundry Doppler Websocket. Optional. Default: "(value from ${api_address}/v2/info)".
+
+[float]
+=== `uaa_address`
+
+The URL of the Cloud Foundry UAA API. Optional. Default: "(value from ${api_address}/v2/info)".
+
+[float]
+=== `rlp_address`
+
+The URL of the Cloud Foundry RLP Gateway. Optional. Default: "(value from ${api_address}/v2/info)".
+
+[float]
+=== `client_id`
+
+Client ID to authenticate with Cloud Foundry. Default: "".
+
+[float]
+=== `client_secret`
+
+Client Secret to authenticate with Cloud Foundry. Default: "".
+
+[float]
+=== `shard_id`
+
+Shard ID for connection to the RLP Gateway. Use the same ID across multiple {beatname_lc} to shard the load of events
+from the RLP Gateway. Default: "(generated UUID)".
+
+[float]
+=== `ssl`
+
+This specifies SSL/TLS common config. Default: not used.
+
+
+[float]
+=== Example configuration
+
+The cloudfoundry module supports the standard configuration options that are described
+in <<configuration-metricbeat>>. Here is an example configuration:
+
+[source,yaml]
+----
+metricbeat.modules:
+- module: cloudfoundry
+ metricsets:
+ - container
+ - counter
+ - value
+ enabled: true
+ api_address: '${CLOUDFOUNDRY_API_ADDRESS:""}'

+ rlp_address: '${CLOUDFOUNDRY_RLP_ADDRESS:""}'
+ client_id: '${CLOUDFOUNDRY_CLIENT_ID:""}'
+ client_secret: '${CLOUDFOUNDRY_CLIENT_SECRET:""}'
+----
+
+[float]
+=== Metricsets
+
+The following metricsets are available:
+
+* <<metricbeat-metricset-cloudfoundry-container,container>>
+
