Hello everyone, im currently trying to set up a REST custom sensor, which returns a json string. To read the json response I need to configure my REST template. My json response: {"diskusage":"50%","ramusage":"2246","cpuload":"7%","cputemp":"54.04"} My Template right now: 

{
   "prtg": {
      "result": [
         {
            "Channel": "ramusage",
	    "CustomUnit": "gb",
	    "Float": 1,
            "Value": $.ramusage
         },
         {
            "Channel": "cputemp",
            "CustomUnit": "°C",
            "Float": 1,
            "Value": $.cputemp
         },
         {
            "Channel": "diskusage",
            "CustomUnit": "%",
            "Value": $.diskusage
         },
	{
	    "Channel": "cpuload",
	    "CustomUnit": "%",
	    "Value": $.cpuload
	 }
      ]
   }
}

Which works perfectly fine for my Integer/ Float values. But for "diskusage" and "cpuload" I get an error. Because value only accept Integers/ Floats but not string.

My Solution would be to cut off the "%" of the 2 values to "convert" it into a Float. But how do I do that? Is there any better way to do this?

Hello Jonas,

Thanks for contacting us.

Unfortunately it is hard to change PRTG here since it is designed to monitor integer values. The only alternative option would be to create a custom script which "translates" the strings into integer values.
