Events

Introduction

Events are messages about actions that have occurred over LXD. Using the API endpoint /1.0/events directly or via lxc monitor will connect to a WebSocket through which logs and life-cycle messages will be streamed.

Event types

LXD Currently supports three event types.

• logging: Shows all logging messages regardless of the server logging level.

• operation: Shows all ongoing operations from creation to completion (including updates to their state and progress metadata).

• lifecycle: Shows an audit trail for specific actions occurring over LXD.

Event structure

Example

location: cluster_name
metadata:
  action: network-updated
  requestor:
    protocol: unix
    username: root
  source: /1.0/networks/lxdbr0
timestamp: "2021-03-14T00:00:00Z"
type: lifecycle

• location: The cluster member name (if clustered).

• timestamp: Time that the event occurred in RFC3339 format.

• type: The type of event this is (one of logging, operation, or lifecycle).

• metadata: Information about the specific event type.

Logging event structure

• message: The log message.

• level: The log-level of the log.

• context: Additional information included in the event.

Operation event structure

• id: The UUID of the operation.

• class: The type of operation (task, token, or websocket).

• description: A description of the operation.

• created_at: The operation’s creation date.

• updated_at: The operation’s date of last change.

• status: The current state of the operation.

• status_code: The operation status code.

• resources: Resources affected by this operation.

• metadata: Operation specific metadata.

• may_cancel: Whether the operation may be canceled.

• err: Error message of the operation.

• location: The cluster member name (if clustered).

Life-cycle event structure

• action: The life-cycle action that occurred.

• requestor: Information about who is making the request (if applicable).

• source: Path to what is being acted upon.

• context: Additional information included in the event.
