Configuration

The following settings are required:

server: The OpAMP server connection settings.
- ws: The OpAMP websocket transport settings.
  - endpoint (no default): The OpAMP server websocket endpoint (URL).

The following settings are optional:

server: The OpAMP server connection settings.
- ws: The OpAMP websocket transport settings.
  - tls: TLS settings.
  - headers: HTTP headers to set.
instance_uid: A ULID formatted as a 26 character string in canonical representation. Auto-generated on start if missing. Setting this ensures the instance UID remains constant across process restarts.
capabilities: Keys with boolean true/false values that enable a particular OpAMP capability.
- reports_effective_config: Whether to enable the OpAMP ReportsEffectiveConfig capability. Default is true.
agent_description: Setting that modifies the agent description reported to the OpAMP server.
- non_identifying_attributes: A map of key value pairs that will be added to the non-identifying attributes reported to the OpAMP server. If an attribute collides with the default non-identifying attributes that are automatically added, the ones specified here take precedence.
ppid: An optional process ID to monitor. When this process is no longer running, the extension will emit a fatal error, causing the collector to exit. This is meant to be set by the Supervisor or some other parent process, and should not be configured manually.
ppid_poll_interval: The poll interval between check for whether ppid is still alive or not. Defaults to 5 seconds.
