vSphere Session Timeout Overview

10.06.2022 by William Lam // 1 Comment

I periodically get questions about vSphere "session timeouts" and because there are several different session timeouts in vSphere, there is usually a back and fourth to understand which session timeout a user is specifically asking about? 🙂

Once the specific vSphere session timeout has been identified, the next series of questions are typically:

  • What is the default or current value?
  • Is it configurable?
  • If so, where and how can I change it?

To help simplify questions around this topic, I have put together this quick overview that also includes details for each specific session timeout and where to find and update the values.

Configuring New vSphere Web Client Session Timeout

09.10.2012 by William Lam // 5 Comments

Just like you could in the old vSphere C# Client, users can also configure a session timeout for the new vSphere Web Client in the latest release of vSphere 5.1. This not only ensures that idle sessions automatically disconnect after a certain period of time but also helps reduce the resources consumed on the vCenter Server as each session allocates a certain amount of resources.

To configure the session timeout, you will need to login to the server running the vSphere Web Client service (which is usually your vCenter Server) and find the webclient.properties file and change the default timeout and then restart the vSphere Web Client service. For the VCSA, the default timeout value is 120 minutes and I assume it is the same default for the Windows vCenter Server.

Step 1 - Locate the webclient.properties file:

    VCSA 5.x

/var/lib/vmware/vsphere-client/webclient.properties

    VCSA 6.x

/etc/vmware/vsphere-client/webclient.properties

    Windows vCenter Server 5.x

%ALLUSERPROFILE%\VMware\vCenterServer\cfg\vsphere-client\webclient.properties

    Windows vCenter Server 6.x

%ALLUSERPROFILE%\VMware\vSphere Web Client\webclient.properties

Step 2 - Un-comment and change session.timeout value to desired value:

session.timeout = 120

Step 3 - Restart the vSphere Web Client Service:

/etc/init.d/vsphere-client restart

You will need to restart the vSphere Web Client service for the changes to go into effect. For the Windows vCenter Server, just restart the vSphere Web Client service and for the VCSA, run the above command.

In my lab, I configured the time out to be 1 minute, once the session has gone idle for the configured period, you will automatically be logged out and brought back to login page with the following message:
