BOSH Prometheus Exporter

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/cloudfoundry-community/bosh_exporter
$ bosh_exporter <flags>

Cloud Foundry

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

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

metrics.namespace_last_service_discovery_scrape_timestamp	Number of seconds since 1970 since last scrape of Service Discovery from BOSH
metrics.namespace_last_service_discovery_scrape_duration_seconds	Duration of the last scrape of Service Discovery from BOSH

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.
