Hi team ,

NSX Version : 6.3.2

Vcenter : 6.0

Esxi 6,0

   We are hosting about 60+ customers in our data-center . All of their NSX ESG are setup as X-large. I am running into issues where for some customers their NSX ESG which is X-large in Size is reaching 100 percent . Since VM's are system Managed ,  I cant increase CPU since option is greyed out .

Hello T180985,

   I already checked that article . That article is NSX 6.2.3 .. We are running NSX 6.3.2 where we dont get " reservation any more ". Please see screenshot .There is no option of "resource reservation " or any way to define CPU .

Hi Tarun

Try to identify what is causing such CPU usage.

I had once similar situation when edge got hit by 100% cpu usage out of nowhere and it was caused by overload of the incoming network traffic from the internet:

1. There was rate limit on this particular network

2. This particular network got impacted by the ddos

3. Internet routers started to drop about 50% of incoming packets in order to stay within the rate limit

4. NSX Edge started to consume 100% CPU - it was busy trying to maintain TCP sessions, retransmitting dropped packets, and such

Regards
