How to Check Uptime of a VMware ESXi

Spread The Knowledge

In this article, we are going to describe how to get up time or boot time of a VMware ESXi host. There are many ways to get up time for an ESXi but we will go in the simplest way. We will show you ESXi uptime through vCenter and ESXi shell. Let’s start it.

1. In vCenter

Log in to the respective vCenter server and search for the host. Under the Summary tab, it shows the uptime. But sometimes it does not show the latest uptime. You may have to refresh the browser or re-login to the vCenter. Refer below snap for the standalone host.

vCenter: ESXi uptime

2. Know the ESXi uptime using ESXi CLI

SSH to the host with root credentials. And enter below commands and hit enter to see the same.


ESXi Uptime
SSH: ESXi Uptime

Alternatively, you can use below commands to see the boot time.

grep booted /var/log/vmksummary.log

ESXi uptime SSH
SSH: ESXi Boot Time

Hope this will help administrators while doing troubleshooting with the ESXi. This is really a small article but very useful. See you in the next article.
