Is there any way to see what date a sensor was added?

Hello,

open the sensor in question and then go to the History Tab.

There you should see when the sensor was created.

1. I should have been a little clearer in my question as I need this information for all the sensors. To look at the history tab for over 400 sensors is not going to be practical or or feasible.

2. Most of the sensors that I have looked at do not have any created date information under their history.

The date of creation is only available in the history tab, and looks like this:

02-Feb-12 13:06:42 PRTG System Administrator Created.

Depending on how many entries you have in each sensors history the initial creation date may have been purged already.

It should be possible to use PRTG's API to get this information for you automatically, but I cannot provide you with a working script for that.

Dirk, Thanks! As far as i can tell the sensors I looked at that did not have a created record only have one or at most 2 entries (usually edits). I am wondering if this information was lost in one of the many updates over the last 5 or so years that we have used this product.

I will look into the API if I need a to pursue this more as it is I think we have an answer to my initial problem (will we need to upgrade to a new license level before the end of our next maintenance contract).

If the sensors are very "old" they may have been created before we actually introduced the lifetime history feature.

BTW: You can update to a higher version at any time, we will arrange maintenance accordingly, you don't loose anything. :-)
