How can add a sensor to measure the CPU load on a router and another one for the memory? I have read that i can use the SNMP sensors but none of them give me the option for CPU nor memory. Thanks in advance.

Hi,
this is dependent on the router itself. Most vendors offer MIB files for the routers supporting SNMP. These MIB files contain more information than the PRTG standard sensors.
You can import a MIB file for the usage in PRTG with the MIB Importer.

Thanks for the reply, we have the CPU and memory sensors in place now for several routers. Now when it comes to the information we are getting, the results an integer (for example 5%) value do not match with the results shown in the graph (0.5%). It only happens on the CPU sensors since we are trying to get the info in %. I checked on the settings "unit string" and it displays "%" as well as the channel for such sensor. Is anything that can be done to resolve this?, so that the results logged in match the graph information.

Thanks in advance.

Hi,
are you using a SNMP Library Sensor as suggested? If so, please see the tab "Settings" where you are able to set own factors for multiplication/division to adjust the values.
Best regards

Hello, I went back and look at the configuration and on the channel tab there was an option for "Downtime" checked that was showing on the chart, so i unchecked that option and the graph then was reflecting the same results as the table logs.

Thanks for the replies.
