Usage

Requirements

In order to use this BOSH release you will need:

• BOSH CLI v2
• An already deployed BOSH environment, please check BOSH deployment security groups because Prometheus will connect to BOSH (ports: 25555 - Director API, 8443 - UAA API)
• A compatible cloud-config with a default option for network and vm_types (you can use the example that comes from cf-deployment)

Although not mandatory, it is recommended to deploy the node exporter addon in order to get system metrics.

Clone the repository

First, clone this repository into your workspace:

git clone https://github.com/bosh-prometheus/prometheus-boshrelease
cd prometheus-boshrelease
export BOSH_ENVIRONMENT=<name>

Then checkout to the release branch you want to use, so manifest files will be in synch with the release version:

git checkout v...

Basic deployment

To deploy a basic prometheus server with alertmanager and grafana (but no exporters) use the following command:

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml

Once deployed, look for the nginx instance IP address:

bosh -d prometheus instances

You can reach each component's web ui at:

• alertmanager: http://<nginx-ip-address>:9093
• grafana: http://<nginx-ip-address>:3000
• prometheus: http://<nginx-ip-address>:9090

Credentials for each components can be located at the tmp/deployment-vars.yml file.

Using BOSH Service Discovery

If you want to use the BOSH Service Discovery in order to dynamically discover your exporters then add the monitor-bosh.yml op file by running the following command (filling the required variables with your own values):

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  -o manifests/operators/monitor-bosh.yml \
  -v bosh_url= \
  -v bosh_username= \
  -v bosh_password= \
  --var-file bosh_ca_cert= \
  -v metrics_environment=

NOTE: metrics_environment is an arbitrary name to identify your environment (test, nyc-prod, ...)

If you have configured your bosh-deployment to use UAA user management (via the uaa.yml ops file) we recommend adding the add-bosh-exporter-uaa-clients.yml op file to your bosh-deployment and then adding the enable-bosh-uaa.yml ops file to the prometheus deployment by running the following command (filling the required variables with your own values):

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  -o manifests/operators/monitor-bosh.yml \
  -o manifests/operators/enable-bosh-uaa.yml \
  -v bosh_url= \
  --var-file bosh_ca_cert= \
  -v metrics_environment=

In case you have configured manually an UAA client_idfor the bosh_exporter (different from bosh_exporter), then run the following command instead:

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  -o manifests/operators/monitor-bosh.yml \
  -o manifests/operators/enable-bosh-uaa.yml \
  -o manifests/operators/configure-bosh-exporter-uaa-client-id.yml \
  -v bosh_url= \
  -v uaa_bosh_exporter_client_id= \
  -v uaa_bosh_exporter_client_secret= \
  --var-file bosh_ca_cert= \
  -v metrics_environment=

Monitoring Cloud Foundry

If you want to monitor your Cloud Foundry platform, first update your cf-deployment adding the add-prometheus-uaa-clients.yml op file.

This will add the UAA clients required to gather information from the Cloud Foundry API and Firehose. Then add the monitor-cf.yml ops file by running the following command (filling the required variables with your own values):

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  -o manifests/operators/monitor-bosh.yml \
  -v bosh_url= \
  -v bosh_username= \
  -v bosh_password= \
  --var-file bosh_ca_cert= \
  -v metrics_environment= \
  -o manifests/operators/monitor-cf.yml \
  -v metron_deployment_name= \
  -v system_domain= \
  -v uaa_clients_cf_exporter_secret= \
  -v loggregator_ca_name= \
  -v skip_ssl_verify=

NOTE: metron_deployment_name property should match the deployment property of your metron_agent or loggregator_agent jobs. Use:

• your system_domain (metron_agent) for cf-deployment before v2.0.0
• cf (loggregator_agent) for cf-deployment starting from the v2.0.0
• cf for Pivotal Application Service

NOTE: loggregator_ca_name property should match the full credhub path of loggregator_ca certificate variable, ex: /bosh-mydirector/cf/loggregator_ca.

NOTE: You can switch to legacy implementation of firehose_exporter and legacy cloud foundry dashboards by adding the following ops-files:

• on prometheus deployment, adapt:

  ...
  -o manifests/operators/monitor-cf.yml \
  -o manifests/operators/deprecated/monitor-cf-attic.yml \
  -v uaa_clients_firehose_exporter_secret= \
  -v traffic_controller_external_port= \
  ...

• When using add-prometheus-uaa-clients.yml on cloud foundry deployment, adapt:

  ...
  -o manifests/operators/cf/add-prometheus-uaa-clients.yml
  -o manifests/operators/deprecated/cf/add-prometheus-uaa-clients-attic.yml
  ...

This will switch deployment to firehose_exporter-attic, cloudfoundry_dashboards-attic and cloudfoundry_alerts-attic

Register Cloud Foundry routes

If you want to access alertmanager, grafana, and prometheus web ui's using your Cloud Foundry system domain instead of IP addresses, then you can register those routes inside your Cloud Foundry environment using the enable-cf-route-registrar.yml op file by running the following command (filling the required variables with your own values):

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  ...
  -o manifests/operators/enable-cf-route-registrar.yml \
  -v system_domain= \
  -v cf_deployment_name=

The op file will register the following routes:

• https://alertmanager.<cf system domain>
• https://grafana.<cf system domain>
• https://prometheus.<cf system domain>

Use UAA for Grafana authentication

If you want to allow users registered at your Cloud Foundry environment to access the Grafana dashboards (Viewer mode only), first update your cf-deployment adding the add-grafana-uaa-clients.yml op file. This will add the UAA client required by the Grafana-UAA integration.

Then add the enable-grafana-uaa.yml op file by running the following command (filling the required variables with your own values):

bosh -d prometheus deploy manifests/prometheus.yml \
  --vars-store tmp/deployment-vars.yml \
  ...
  -o manifests/operators/enable-grafana-uaa.yml \
  -v system_domain= \
  -v uaa_clients_grafana_secret= \
  --var-file uaa_ssl.ca= \
  --var-file uaa_ssl.certificate= \
  --var-file uaa_ssl.private_key=

Operations files

Additional operations files are located at the manifests/operators directory. Those files includes a basic configuration, so extra ops files might be needed for additional configuration.

Please review the op files before deploying them to check the requirements, dependencies and necessary variables.

Deployment variables and the var-store

Some operators files requires additional information to provide environment-specific or sensitive configuration such as various credentials. To do this in the default configuration, we use the --vars-store. This flag takes the name of a yml file that it will read and write to. Where necessary credential values are not present, it will generate new values based on the type information stored at the different deployment files. Necessary variables that BOSH can't generate need to be supplied as well. See each particular op files you're using for any additional necessary variables.

See also the BOSH CLI documentation for more information about ways to supply such additional variables.
