Hello,

After upgrading PRTG to version 12.4.7.3507 and running auto-discovery, discovered many System Health Currents sensors of type SNMP Cisco System Health. Most of the sensors are showing uA error which is something new in the system. Can you explain the meaning of the error ?

Thank you

The unit uA means microampere. "Micro" is a so called metric prefix. It means 1 / 1.000.000 (for further information please take a look at http://en.wikipedia.org/wiki/Metric_prefix). Actually the "micro" is represented by the greek letter "Mu", but as this letter is not available on a regular english keyboard, it is usually replaced by a "u".

When creating the sensor, PRTG does not only read the values, but also the threshholds, that are configured on your cisco device. These threshholds are used as channel limits. As soon as a value does not match the configured limits, you will get an error message.

The Channel limits are predefined by PRTG, but you can change the limit for every channel, as you want. Please take a look at our manual http://www.paessler.com/manuals/prtg/sensor_channels_settings.htm to get details about the channel limit settings.
