Port speed on Server




I have some Esxi,windows and Linux Servers and the switch port speed is 1000.but for some reasons they could be available and up with 100Mbps speed.I want a sensor to add and alarm me which interface on my server is 100Mbps.How I can Achieve this?

Are we talking about VMs or physical ports?

What kind of switches do you use?

There are various ways - as for Linux there might be an SNMP query - as for Windows there should be a WMI query and ESXi - well - those are for sure connected to physical switches so just monitor the ports there - per SNMP.

Thanks Florian

we are talking about some physical windows and Esxi host servers.we have Cisco switch.

I can add SNMP traffic sensor but it shows port speed only on sensor creation,I want to have port speed after sensor creation.what can I do? you said we have port speed on connected physical port switch.Please let me know what is the sensor name?

I find https://gshaw0.wordpress.com/2017/05/04/quick-tips-custom-port-speed-sensor-for-prtg/ but it seems it works for 10G network.I want it for 1G network.

Hello Sara,

the values given, in the linked article's case 10G, refer to the information provided by the queried device. It's not said, that you receive the very same values.

You might also check out Stephan's reply here. Please let us know if that suits you.

Best regards,
