Tsuru Usage

This project aims to provide an easy way to expose some resource usage about a tsuru installation. The project contains an Procfile and this code can be ran as an application on tsuru.

This app will expose usage metrics on a /metrics endpoint. Two main metrics are available:

• tsuru_usage_units{app="apptest",plan="autogenerated",pool="theonepool"} 5
• tsuru_usage_nodes{pool="theonepool"} 2

Installing and Running

1. Create a go application on tsuru
2. Deploy this entire repo to tsuru
3. Set USAGE_USER_TOKEN environment on the app passing a token that has at least the following permissions (with global context):
   • app.read
   • node.read
4. Set API_HOST environment variable to tsuru-usage API host address (ex: http://localhost:8888)
5. Set PROMETHEUS_HOST environment variable to your Prometheus server address
6. Set MONGODB_URL and MONGODB_DATABASE_NAME variables to your MongoDB server credentials
7. Set in USAGE_SERVICES a comma-separated list of services you want Prometheus to monitor
8. To add basic HTTP authentication to the admin section, set ADMIN_USERNAME and ADMIN_PASSWORD environment variables
