I have a custom sensor configured to capture a string value. It displays the result without issue. My problem is that I cannot see any history of the responses. My goal is to be able to be notified of the change (this is already working) and look at the sensor to see what the string value was previously. I'm not trying to graph it so I don't want to extract anything.
Is it possible to capture this value in a channel?
An example of how one could display it is using the SNMP Cisco ASA VPN Users sensor. It displays each value it has ever received as a new channel and then marks it as online or offline. I'm assuming this is based on a lookup table.
Is this possible?
