No Data does not equal Error in custom lookup

Votes:

0

I defined a custom lookup and when there is no data on a given channel the sensor is still "OK" ?!

How can I switch it to "Error"? and please ... no value limits ...

<?xml version="1.0" encoding="UTF-8"?> <ValueLookup id="lookup.snmp.freebsd.service" desiredValue="1" undefinedState="Error" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="PaeValueLookup.xsd"> <Lookups> <SingleInt state="Ok" value="1"> running </SingleInt> <SingleInt state="Ok" value="2"> runnable </SingleInt> <SingleInt state="Warning" value="3"> notRunnable </SingleInt> <SingleInt state="Error" value="4"> invalid </SingleInt> </Lookups> </ValueLookup>

Hello,
Which sensor type are you using exactly? Feel free to reach out to us directly via mail at [email protected] so we can take a closer look at screenshots of the issue you are referring to. In general if there's no data returned by the target device but the sensor was executed successfully, the sensor/channel should be displayed as Unknown/Grey.
