I have numerous servers (HP) that are displaying the wrong % utilisation on the interfaces within the Node Details screen, this became apparent yesterday when the Transmit reading went to 131%. In the past when I have spotted this I have checked that NPM has recognised the correct NIC speed and if it hasn't I have modified it but in this case and a few others NPM is showing the correct speed for the interface.
So why is it reading this wrong and how can I get it to show the correct utilisation, this is still a new system with us and seeing percentages over 100% will not give the users confidence in its accuracy.
Any ideas?
