Hi, first of all thank you for this great product.
We have a tiny problem, that ve if it's not of your business, I think it could be really helpful:
We have a Datacenter with people monitoring all the time the PRTG sensors. When there´s a problem with one, for example a ping sensor monitoring communications to a branch office went down or have high latency, the Datacenter starts to diagnose what is the problem.
The thing is that monthly we need to make a report, and when someone looks at the graph and asks what happened in a special alarm event during a lapse of time, is kind of hard to remember what happened at that time. (even more if the report is from 3 months or older). I think if it´s possible for you to add like a tag timeline, where when something happens you click on the graph or something on that specific time and write down a small description of what happened (even a ticket number). Or when a traffic sensor shows a unusual behavior, the operator can clic on that part and add a small description of what he found. Or something like the description you can write down when you pause a sensor.
I know it´s kind of a long shot to ask you this, but hey...may be you like the idea or have a better one already working and I don't know it.
