Have you checked in the vSphere Client performance graphs for Network packet loss?

Do you in general experience high CPU load and / or high network traffic in your ESXi host?

in the past I've noticed ports on switches do go bad so that too could be an issue?

or are there other VMs on the same physical port that have no issue?

Hi ,

The alert was tiggered by hp ovo agent ( installed in each vm ). once we received the ticket from our helpdesk and we check the machine it's running properly and we check the alerts in vcenter but vcenter doesn't shown anything alert/event on that time.  i.e ovo tiggeres an alert at 8.7 pm we receive ticket only at 10 pm, on that time the machine was running propperly, the pocket drops happens randomly and it takes 1 or 2 minutes only. on that time there is no alret regrading this pocket drop in vcenter.

Any suggestion

Regards,

Karthick.

Hoa many VMs on the same host facing this issue ?

Do you see this when you migrate the VM to other hosts ?

Have verified speed and duplex settings on nic and switch ?
