Cloud Foundry Firehose Exporter

A Prometheus exporter proxy for Cloud Foundry Firehose metrics. Please refer to the FAQ for general questions about this exporter.

Architecture overview

Installation

Binaries

Download the already existing binaries for your platform:

$ ./firehose_exporter <flags>

From source

Using the standard go install (you must have Go already installed in your local machine):

$ go install github.com/cloudfoundry/firehose_exporter
$ firehose_exporter <flags>

Docker

To run the firehose exporter as a Docker container, run:

$ docker run -p 9186:9186 boshprometheus/firehose-exporter <flags>

Cloud Foundry

The exporter can be deployed to an already existing Cloud Foundry environment:

$ git clone https://github.com/cloudfoundry/firehose_exporter.git
$ cd firehose_exporter

Modify the included application manifest file to include your Cloud Foundry Firehose properties. Then you can push the exporter to your Cloud Foundry environment:

$ cf push

BOSH

This exporter can be deployed using the Prometheus BOSH Release.
