View Cloud VPN maintenance events

You can view maintenance event logs by using the Google Cloud console.

Console

  1. In the Google Cloud console, go to the Logs Explorer page.

    Go to Logs Explorer

  2. Select the Cloud VPN Gateway as Resource Type.

  3. In the Logs column, click View.

    The default query appears in the query builder.

  4. From the default query, note the value of the tunnel ID of the resource.labels.tunnel_id variable.

  5. Build a new query by using the resource.labels.tunnel_id value from the previous query as follows:

    resource.labels.tunnel_id=TUNNEL_ID textPayload=~"Starting VPN
Task maintenance"

  6. Check the logs for the following messages:

    • Starting VPN Task maintenance: this message indicates the beginning of the maintenance process for a specific VPN task.

    • VPN task maintenance Completed: this message confirms that the maintenance for the VPN task has successfully finished.

These maintenance activities are designed to be non-disruptive, so that users have continuous service—no packet loss, service interruptions, or downtime during these events.
