Agent Health Check API

Note: Using this feature requires atleast version 17.11.0 of the GoCD server and agent.

The health check API allows users to monitor if the agent is connected to the server and is authorized to perform a build.

Configurations

The API uses the following configurable agent system properties.

Property Values
go.agent.status.api.enabled Defaults to true. Set to false to disable health check api end-point
go.agent.status.api.bind.host Defaults to localhost.Set to a specific ip address or hostname to bind to that host. Set to 0.0.0.0 to bind to all network interfaces.
go.agent.status.api.bind.port Defaults to 8152. Set to 0 to use an ephemeral port, which will be displayed in a log statement.

*In case the http server is unable to bind (usually because of port conflicts, or multiple agents running on the same machine), a warning will be emitted to the console log and agent startup will continue.

Configuring Health API for multiple Agents on a Single Machine

In case of multiple agents running on a single machine, the user must explicitly configure the go.agent.status.api properties for each of the agents.

On Linux Machine

To configure the properties on linux machine, edit the file corresponding to the agent at /etc/default/go-agent

GO_AGENT_SYSTEM_PROPERTIES=-Dgo.agent.status.api.bind.port=8158

Or have the following property set in the agent shell

export GO_AGENT_SYSTEM_PROPERTIES=-Dgo.agent.status.api.bind.port=8158

On Windows Machine

Follow the instructions to add a new property for GoCD agents setup on windows
