Learn how to install the Loggregator Firehose Plug-in for the Cloud Foundry Command Line Interface (cf CLI).
The Loggregator Firehose plugin 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 plugins with the cf CLI, see Using cf CLI Plugins.
If you don’t want to use 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.
Before you install the Loggregator Firehose plug-in, you need these prerequisites:
Admin access to the TAS for VMs deployment that you want to monitor
