In some of my monitors of the type "ping" I got constant errors of this type:
"Monitor Run Exception - Ungültige Konvertierung von der Zeichenfolge in Typ Boolean."
which in english means : "unvalid conversion from string to type booelan"
Is that a bug? Thre ping monitor hostname is an IP adress.
And there is another .Net error. If I click on any "View History & Trends" - Icon in the Dashboard, I get an error alert. I made a screenshot you can see
here. I think this is a bug, too.
