Hello,

Could you please say, is it possible to create Sensor which will return "1" - if sensor status is down, and "0" - if sensor status is up? As example: Sensor check file on X drive, if file not exist, then value of Sensor will be "1"; If file exist, then it return "0"; or Sensor check web site for string, if string not found, sensor return value "1"; if string found then sensor return "0";

Thanks in advance!

Best regard, Oscar

The status of a sensor usually depends on the return value, not the other way around. But there are things that can be done with a Custom Sensor.

For example the existence of a file can be checked with a simple batch file sensor that returns "1" if the file does not exist:

@echo off
if exist %1% goto exists
echo 1:File does not exist
goto end
:exists
echo 0:File exists
:end

Hello,

As I understand notification can be setup if value of received sensor is more than "x" But if I will get those values using batch script "0" or "1", is it possible to create alarm/trigger only if value "1" (down) is received? and alarm/trigger off if "0" value received?

Thank you!

Best regards, Oscar

Go to the sensors channels tab and enable limits. Next you can set the limits for warning and error status.

In your case set the "upper error limit" to 0
