Page last updated:
This topic describes how to install the Loggregator Firehose Plugin for the Cloud Foundry Command Line Interface (cf CLI).
The Loggregator Firehose plugin for the cf CLI allows Cloud Foundry admins to access the output of the Loggregator Firehose. The output of the Firehose includes logs and metrics from apps deployed on Cloud Foundry as well as metrics from Cloud Foundry platform components.
