This documentation describes the Splunk Firehose Nozzle for VMware Tanzu. Splunk Firehose Nozzle integrates with the VMware Tanzu Loggregator and forwards streaming logs and metrics from user apps and system components of Cloud Foundry to Splunk Enterprise. VMware Tanzu operators can then gain operational visibility over their VMware Tanzu infrastructure, including the health and performance of their apps and system components.

For more information about Loggregator, see the Loggregator Architecture topic in the Pivotal documentation.
