Transforming a value to string to use in custom error message

[DanG]

Current I report the current value of the DCI using the %<currentValue>
For the ServiceCheck.HTTP the value can be 0 to 3.
I would rather have a textual description instead of the numerical value. I thought of using a the transformation script but this will change the type from int to string which cannot be graphed.
Another place where I could do this is in the filtering script where CUSTOM_MESSAGE can be set.

sub main()
{
 CUSTOM_MESSAGE = "";
 
 if($1->value == 2)
 {
  CUSTOM_MESSAGE = "cannot connect to server";
 }
 else
 if($1->value == 3)
 {
  CUSTOM_MESSAGE = "content of does not match";
 }

  return true;
}

How do I test the “value” within the filtering script ($1->value above does not work of course) ?
Or maybe there's a better solution?

Hi!

I would suggest calling a script from macro, like this:

1. Create script called "ServiceStateName" in script library:

state = GetEventParameter($event, "currentValue");
switch(state)
{
   case 0:
      return "OK";
   case 1:
      return "error in parameters";
   case 2:
      return "cannot connect to server";
   case 3:
      return "content of does not match";
}
return "UNKNOWN";

2. Use %[ServiceStateName] instead of %<currentValue>
