vCenter Server 5.1/5.5/6.0 performance charts report dropped network packets

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• The Network Performance Charts in vCenter Server 5.1, 5.5 and 6.0 show dropped packets under the Receive Packets Dropped counter.
• The Network Performance Charts in vCenter Server 5.1, 5.5 and 6.0 show dropped packets under the Transmit Packets Dropped counter.
• This issue can occur when the virtual machine or the host is experiencing a high CPU load and cannot work-down the IP packets in each buffer.

Cause

This issue occurs when packets filtered by the I/O chain are incorrectly recorded as dropped packets. This is a reporting issue, the packets are not dropped, therefore they cannot be seen using esxtop or other network monitoring tools.
