NVGRE troubleshooting with Microsoft Message Analyzer

We had one case where we noticed some network problems on VMs which were using NVGRE. This blog post shows quickly how to use Microsoft Message Analyzer to troubleshoot network problems.

First download Microsoft Message Analyzer HERE and install it on the where gateway VM is running

Start Message analyzer (run as administrator) and create new live Trace:
analyzer01

Create new live trace:
analyzer02

selected “Local Network Interfaces (Windows 8.1/Windows Server 2012 R2)”:analyzer03

 

Capturing started:analyzer04

You are able to filter session with different variables.
For troubleshooting its recommended to install Message Analyzer to host where gateway VM is running and host where problem VM is running.

You can easily filter traffic with MMA for example with IP address:
analyzer05

You can also filter traffic only from dedicated VM from Advanced Settings of Microsoft-Windows-NDIS-PacketCapture
