Concourse pipeline for deploying Prometheus to monitor Pivotal Cloud Foundry

This pipeline is only compatible with PCF 1.12 and newer. If you are using an older version then please use this pipeline instead.

Main differences compared to the old pipeline:

• it uses manifests from prometheus-boshrelease
• it deploys more VMs (firehose_exporter has a dedicated VM, there is a database for Grafana)
• pipeline property names changed to match the manifests
• it automatically discovers some of the properties by querying OpsManager (that's why it requires PCF 1.12+)
• it uses a named runtime-config (a relatively new BOSH feature)
• it only uses BOSH CLI v2 (directly and through BOSH Deployment Resource)

This pipeline deploys Prometheus BOSH release to monitor PCF but can be deployed to a separate BOSH Director. Use director_for_deployment property to configure whether you want to deploy it to OpsManager Director or a separate BOSH Director.

How it works

This is a high-level overview of monitoring Cloud Foundry with Prometheus

Notes:

• since Prometheus uses a pull mechanism, connections are initiated by Prometheus
• most of exporters are colocated with Prometheus (exceptions: firehose exporter has a dedicated VM and node_exporter is a BOSH add-on and runs on all VMs)
• prometheus-boshrelease includes a number of other exporters you can use which are not used in this example; you can see them here

Installation

First of all, have a Concourse running. If you don't have Concourse yet, you can quickly spin one up using BUCC or Concourse-Up.

• clone this repository
• copy pipeline/params.yml to a different place (to avoid polluting the GIT repo)
• edit the params accordingly (there are helpful comments)
• fly -t target set-pipeline -p deploy-prometheus -c pipeline/pipeline.yml -l your-params.yml
• fly -t target unpause-pipeline -p deploy-prometheus
• trigger create-uaa-clients job manually
• trigger install-node-exporter job manually
• trigger deploy job manually

How to use it

If the deployment was successful use bosh vms to find out the IP address of your nginx server. Then connect:

• https://NGINX:3000 to access Grafana
• https://NGINX:9090 to access Prometheus

There is a number of ready to use Dashboards that should be installed automatically. You can edit them in Grafana or create your own. They are coming from prometheus-boshrelease/jobs.

Alertmanager

Warning Current version doesn't allow you to easily configure your alertmanager notifications. This should be fixed soon.

The prometheus-boshrelease does include some predefined alerts for CloudFoundry as well as for BOSH. You can find the alert definitions in prometheus-boshrelease/jobs. Check the *.alerts rule files in the corresponding folders.

Access the AlertManager to see active alerts or silence them:

• https://NGINX:9093

All configured rules as well as their current state can be viewed by accessing Prometheus:

• https://NGINX:9090/alerts
