You're viewing documentation for a prior version of Migrate for Compute Engine (formerly Velostrata). You can continue using this version, or use the current version.

Viewing Stackdriver logs

If enabled, you can take advantage of the power of Google Cloud's operations suite Logging to diagnose problems with your Velostrata environment. You can also share these logs with Velostrata support to speed up problem resolution.

All Velostrata logs are sent to Google Cloud's operations suite in the project that is hosting the Velostrata Manager.

Each Velostrata deployment has a unique ID, which is reflected in the Google Cloud's operations suite namespace resource label.

Using the Google Cloud's operations suite Logging console

The Google Cloud's operations suite documentation has documentation on how to filter and search from the logging console. The directions below assume your familiarity with this interface.

Finding your Namespace

To find your Namespace id:

  1. Sign in to your Manager
  2. Click System Settings
  3. Click the Logs tab
  4. Copy the System ID (for example QWEX1234) on the bottom of page. This is your Namespace for use in Google Cloud's operations suite

Filtering Google Cloud's operations suite Logs

For more information on viewing Google Cloud's operations suite Logs, see the documentation

  1. Go to the Logs Viewer page
  2. On the top bar of the page, verify that you have selected the correct project.
  3. In the resource-type drop-down list, select Generic Node Resource (resource.type="generic_node").

Here you can filter for one or both of the following levels:

A. namespace, using the value you copied above. The Namespace allows you to view only the logs from your Velostrata environment.

B. Individual Velostrata components can be filtered by the following monitored_resource labels:

  • Velostrata_Manager
  • Velostrata_CloudExtensionNode
  • Velostrata_OnPremBackend
  • Velostrata_ManagedVM, which contains logs for operations Velostrata started on migrated VMs. It does not include system logs from those VMs.

For example, to filter for logs only from your Cloud Extensions, use the text box at the top of the log list and paste label:monitored_resource:Velostrata_CloudExtensionNode.

Select logs from Cloud Extensions only in Google Cloud's operations suite using label:monitored_resource:Velostrata_CloudExtensionNode
