Look in the Web Client in order to get more information and resolve them. Also, it'd help to take a few minutes and thoroughly read the post in my signature to learn how to make a better post.
I looked at the web client but couldn't see or find anything. How can I find the exact cause? virtual machine cpu or memory usage comes to load this alarm or something else
You need to look under Administration => System Configuration to see the state of the services referenced by those alarms.
do you have any comment ?
I would say you need to upgrade and use the vCenter Server Appliance. Some of these are known issues with an early version of 6.0 and on Windows. Besides that, the Windows-based vCenter is now gone and the only future is on the appliance. Getting off the Windows 6.0 vCenter is the best thing you can do at this point.
Many thanks for your evaluation. Is there a document that might have problems like this? so I want to show it to my boss. I am using Vcenter 6.0 u2. How to update to 6.0u3 appliance version. I need to upgrade or install a new vCenter appliance? there is one vcenter but there are two clusters . one of them vsan cluster .the other one is normal vmware cluster
You cannot go from the Windows vCenter of 6.0 to the vCSA of 6.0. Your option here is to upgrade to 6.5 and get on the appliance.
