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-community/firehose_exporter
$ firehose_exporter <flags>

Cloud Foundry

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

$ git clone https://github.com/cloudfoundry-community/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.

Usage

UAA Client

In order to connect to the Cloud Foundry Firehose a client-id and client-secret must be provided. The client-id must have the doppler.firehose authority.

For example, to create a new client-id and client-secret with the right permissions:

uaac target https://<YOUR UAA URL> --skip-ssl-validation
uaac token client get <YOUR ADMIN CLIENT ID> -s <YOUR ADMIN CLIENT SECRET>
uaac client add prometheus-firehose \
  --name prometheus-firehose \
  --secret prometheus-client-secret \
  --authorized_grant_types client_credentials,refresh_token \
  --authorities doppler.firehose
