Threshold notification between two number or define limit warnings that warning are in two numbers

I have to tell you that this is not possible with our channel limits. These limits only provide an upper and lower threshold, so the OK-range has to be in between these boundaries. In your case this logic would be reversed, which is not possible. What you can do is to implement this logic in your own custom sensor.

Kind regards,

Greeting! I am currently using a Custom Sensor (SNMP Custom Sensor). I would ask for your help on how to do the above with the mentioned sensor.

Hello,

Regarding your need, I invite you to create your own custom lookup file by using the Range type. Here is the manual regarding lookups: https://www.paessler.com/manuals/prtg/define_lookups

To help you creating your template, here is the prtg.standardlookups.snmpprinter.cartridgelevel lookup (available in PRTG) as an example:

<?xml version="1.0" encoding="UTF-8"?>
  <ValueLookup id="prtg.standardlookups.snmpprinter.cartridgelevel" desiredValue="100" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="PaeValueLookup.xsd">
    <Lookups>
       <Range state="Ok" from="16" to="100">
        Ok
      </Range>
      <Range state="Warning" from="6" to="15">
        Low
      </Range>
      <Range state="Error" from="0" to="5">
        Critical
      </Range>
	  <Range state="Ok" from="-1" to="-1">
        No Restriction
      </Range>
      <Range state="None" from="-2" to="-2">
        Unknown
      </Range>
      <Range state="Ok" from="-3" to="-3">
        Not Empty
      </Range>
    </Lookups>
  </ValueLookup>

When you have created your lookup file, please copy it in the following folder "C:\Program Files (x86)\PRTG Network Monitor\lookups\custom".

Then, in the channel settings you should be able to select your own lookup. If you do not see it in the list, you can reload the lookups by using the button GO! under Setup > System Administration > Administrative Tools > Load Lookups and File Lists (/systemsetup.htm?tabid=7).

Kind regards.
