AKS turning on network watcher linux extension

Sometimes we need to do some packet capture or even do some network monitoring for AKS cluster's running nodes. To do that we first need to configure the network watcher linux extension. 

To do that, goto your AKS's VMSS instance by going to AKS cluster -> Properties -> Infrastructure resource group -> Select your VMSS. 



Find and install the following extension



Even after i installed it, I was able to do my packet capture. Make sure you have check "Network watcher"



Once you kick start the process, it will start to run. Then you can stop if by right clicking on your newly created job and select "Stop" packet capture.

The file is a pcap file. 




You can open up the pcap file using tools like wireshark.
