Telemetry

This component provides the following metrics that can be retrieved through the internal_metrics source. See the metrics section in the monitoring page for more info.

• counter

  encode_errors_total

  The total number of errors encountered when encoding an event. This metric includes the following tags:

  • instance - The Vector instance identified by host and port.

  • job - The name of the job producing Vector metrics.

• counter

  events_in_total

  The number of events accepted by this component either from tagged origin like file and uri, or cumulatively from other origins. This metric includes the following tags:

  • component_kind - The Vector component kind.

  • component_name - The Vector component ID.

  • component_type - The Vector component type.

  • container_name - The name of the container from which the event originates.

  • file - The file from which the event originates.

  • instance - The Vector instance identified by host and port.

  • job - The name of the job producing Vector metrics.

  • mode - The connection mode used by the component.

  • peer_addr - The IP from which the event originates.

  • peer_path - The pathname from which the event originates.

  • pod_name - The name of the pod from which the event originates.

  • uri - The sanitized uri from which the event originates.

• counter

  events_out_total

  The total number of events emitted by this component. This metric includes the following tags:

  • component_kind - The Vector component kind.

  • component_name - The Vector component ID.

  • component_type - The Vector component type.

  • instance - The Vector instance identified by host and port.

  • job - The name of the job producing Vector metrics.

How It Works

Health checks

Health checks ensure that the downstream service is accessible and ready to accept data. This check is performed upon sink initialization. If the health check fails an error will be logged and Vector will proceed to start.

Require health checks

If you'd like to exit immediately upon a health check failure, you can pass the --require-healthy flag:

vector --config /etc/vector/vector.toml --require-healthy

Disable health checks

If you'd like to disable health checks for this sink you can set the healthcheck option to false.

State

This component is stateless, meaning its behavior is consistent across each input.
