Collect Logs for Google Cloud IAM

Collect logs for the Google Cloud Identity and Access Management (Cloud IAM) app.

This page has instructions for configuring Google Cloud IAM to send logs to Sumo.

Configure Cloud IAM to export logs to Stackdriver

If you haven't already done so, set up Google Cloud IAM to export logs to Stackdriver. For more information, see Overview of Logs Export in GCP.

Set up a Google-validated HTTP source and Pub/Sub topic

In this step, you set up an HTTP source in Sumo, register it with Google, and create a Pub/Sub topic to send data to the HTTP source. Follow the instructions in Google Cloud Platform Source.

Create export of Cloud IAM logs from Stackdriver

  1. Click Logging in the STACKDRIVER section in the left hand pane of the GCP console.
  2. Go to Exports. Click Create Export.
  3. Create a sink for each GCP service whose logs you want to send to Sumo. We recommend you create sinks for the following services:  Google Project, IAM Role, and Service Account. To configure a sink:

    1. Select the service in the middle pane (Google Project, IAM Role, or Service Account).

    2. In the Edit Export window on the right:

      • Set the Sink Name. For example, "google-project".
      • Set Sink Service to “Cloud Pub/Sub”
      • Set Sink Destination to the newly created Pub/Sub topic. For example, "pub-sub-logs".
      • Click Create
