Hi Yuni and all,

 

Can you please share you experience. We have developed big-ip ver 14 running on top of openstack liberty.

 

We are facing an issue, if we check from the dashboard F5 instance the CPU usage less than 10%, but if we check from the Host the CPU usage more than 800%. Is it normal ? Our host using 2 socket, each socket 20 cores, so total physical cores 40, 80cores with hyperthread.

 

Is it fine if we will switch the traffic through this F5 CGNAT VM ? Since we are wondering why the CPU of the host very high. This host only running thisn VM only.

 

Really appreciate yor insight.

 

Thank you. Bandung
