abacus-cf-bridge

CF app usage reporting bridge.

UAA Client

Register cf-bridge application as CF client with:

gem install cf-uaac
uaac target uaa.10.244.0.34.xip.io
uaac token client get admin -s admin-secret
uaac client add bridge --authorized_grant_types client_credentials --authorities cloud_controller.admin --secret secret

Note: Currently the client ID and secret are hardcoded

Start the bridge

To start the bridge with CF running on bosh-lite set the API and UAA addresses:

export API=https://api.10.244.0.34.xip.io
export UAA=https://uaa.10.244.0.34.xip.io

You can optionally enable the debug output with:

export DEBUG=abacus-cf-*

Finally start the bridge with:

cd ~/workspace/cf-abacus
npm start bridge

To stop the bridge:

npm stop bridge

Usage reporting

The bridge reports the metrics defined in linux-container resource:

  • instance_memory [GB]
  • running_instances [number]

For every app usage event from CF the bridge POSTs time-based usage report as follows:

  • for STOPPED event: reports 0 memory and 0 insances since the timestamp in the STOPPED event
  • for other events: reports the actual memory and number of instances since the timestamp of the event
