Setup

Metric collection

Installation

If you haven’t already, set up the Google Cloud Platform integration first. There are no other installation steps.

Log collection

Google Cloud Spanner logs are collected with Stackdriver and sent to a Cloud pub/sub with an HTTP push forwarder. If you haven’t already, set up a Cloud pub/sub with an HTTP push forwarder.

Once this is done, export your Google Cloud Spanner logs from Stackdriver to the pub/sub:

  1. Go to the Stackdriver page and filter Google Cloud Spanner logs.
  2. Click Create Export and name the sink accordingly.

  3. Choose “Cloud Pub/Sub” as the destination and select the pub/sub that was created for that purpose. Note: The pub/sub can be located in a different project.

    Export Google Cloud Spanner Logs to Pub Sub

  4. Click Create and wait for the confirmation message to show up.
