Hey @MohamedKamal01,
Which ESXi version and build are you using? From which vendor is your server?
Also when this error appear, what does the vpxd.log located in /var/log/vpxd inside the vCenter Appliance shows?
Also, what hardware are you using for your ESXi host(s)? Not all vendors have a plugin with which you can retrieve this information.
