BOSH Prometheus Exporter Build Status

A Prometheus exporter for BOSH metrics. Please refer to the FAQ for general questions about this exporter.

Architecture overview

Installation

Binaries

Download the already existing binaries for your platform:

$ ./bosh_exporter <flags>

From source

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

$ go install github.com/bosh-prometheus/bosh_exporter
$ bosh_exporter <flags>

Docker

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

$ docker run -p 9190:9190 boshprometheus/bosh-exporter <flags>

Cloud Foundry

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

$ git clone https://github.com/bosh-prometheus/bosh_exporter.git
$ cd bosh_exporter

Modify the included application manifest file to include your BOSH 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.

[1] When BOSH delegates user managament to UAA, either bosh.username and bosh.password or bosh.uaa.client-id and bosh.uaa.client-secret flags may be used; otherwise bosh.username and bosh.password will be required. When using UAA and the bosh.username and bosh.password authentication method, tokens are not refreshed, so after a period of time the exporter will be unable to communicate with the BOSH API, so use this method only when testing the exporter. For production, it is recommended to use the bosh.uaa.client-id and bosh.uaa.client-secret authentication method.

Service Discovery

If the ServiceDiscovery collector is enabled, the exporter will write a json file at the sd.filename location containing a list of static configs that can be used with the Prometheus file-based service discovery mechanism:

[
  {
    "targets": ["10.244.0.12"],
    "labels":
      {
        "__meta_bosh_job_process_name": "bosh_exporter"
      }
  },
  {
    "targets": ["10.244.0.11", "10.244.0.12", "10.244.0.13", "10.244.0.14"],
    "labels":
      {
        "__meta_bosh_job_process_name": "node_exporter"
      }
  }
]

The list of targets can be filtered using the sd.processes_regexp flag.
