Installing the Loggregator Firehose Plug-in for cf CLI

You can use the Loggregator Firehose Plug-in for the Cloud Foundry Command Line Interface (cf CLI).

The Loggregator Firehose plug-in for the cf CLI allows VMware Tanzu Application Service for VMs (TAS for VMs) admins to access the output of the Loggregator Firehose. The output of the Firehose includes logs and metrics from apps deployed on TAS for VMs as well as metrics from TAS for VMs platform components. For more information about the Firehose, see the Loggregator Architecture section of the Loggregator Architecture topic.

For more information about using plug-ins with the cf CLI, see Using cf CLI plug-ins.

You can deactivate the Firehose. In place of the Firehose, you can configure an aggregate log and metric drain for your foundation: For more information, see Configure System Logging in Configuring TAS for VMs.
