How do I know for how long an instance has been running on GCP

Question

I want to know for how long an instance has been running. How do I find this out?

Answer 1

If you SSH into the instance you can run the command uptime -p and it will show you how long the instance has been running.

Alternatively, if you are using gcloud, you could execute this command:

 gcloud compute --project <project_id> ssh --zone <zone> <instance-name> -- command 'uptime'
