When you make an update to a VM that mutates (alters) data, or when a host event occurs that changes the state of a VM, Compute Engine adds an entry to the list of operations. This page describes how you can view a list of completed Compute Engine operations by using the Google Cloud console, the Google Cloud CLI, or REST.
Before you begin
-
If you haven't already, set up authentication.
Authentication is
the process by which your identity is verified for access to Google Cloud services and APIs.
To run code or samples from a local development environment, you can authenticate to
Compute Engine as follows.
Select the tab for how you plan to use the samples on this page:
Console
When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
-
Install the Google Cloud CLI, then initialize it by running the following command:
gcloud init
- Set a default region and zone.
REST
To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.
Install the Google Cloud CLI, then initialize it by running the following command:
gcloud init
-
Viewing operations
To view a list of operations for your project, perform the following steps:
Console
In the Google Cloud console, go to the Operations page.
For more details on an operation, click the operation summary. For example, to view the migration details for the
my-instance
VM, click the Automatically migrate an instance operation.
gcloud
To view a list of operations for your project
using gcloud compute
, use the operations list
sub-command.
To view the list of operations in a specified zone, add the --filter
flag.
gcloud compute operations list --filter="zone:(ZONE)"
Replace ZONE
with the zone where you want to view a list of
operations. For example, to view the list of operations in us-cental1-c
,
run the following command:
gcloud compute operations list --filter="zone:(us-central1-c)"
The output is similar to the following:
NAME TYPE TARGET HTTP_STATUS STATUS TIMESTAMP
systemevent-1543845145000... compute.instances.migrateOnHostMaintenance us-central1-c/instances/my-instance 200 DONE 2018-12-03T05:52:25.000-08:00
REST
API requests for operations must be specified at either the global, region, or zone level. Live migration, VM stopping, and automatic restarts are all zone-level operations.
For zone operations, make a GET
request to the zoneOperations.list
method.
GET https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/operations
Replace the following:
PROJECT_ID
: the project ID for this requestZONE
: the zone for this request
Leave the request body empty.
The following is a sample output for a zone operation request. In this output, details for a host migration displays.
