I'm trying to monitor uptime for my devices. I'm using a perl script that only returns 0 (down) or 1 (up) to that purpose, but I can see decimal values from 0 to 1 in my graphs.
How is it possible?
It's probably averaging the value over the five minutes.
Perhaps it will help to check the 'Use only integers' option under the template/custom graph items.
Yes, when I noticed the error I checked this option in the Template Graph, but remains the problem in the devices...
