My PRTG Graphs have gaps, and worse, aren't displaying as outages when they're down.
This is a ping graph as you should be able to see, and our internet dropped at 4:00.39 and we didn't see another ping until 4.04.29 and a few other times after that.
As you can see there's no data that comes thorugh but rather than report downtime, it's just empty! How can i change this?
I'll explain the situation in case i've gone the wrong way:
My home site support multiple sites branches. These branch sites use data at my home site. My Home site being down means no branch sites can use data, so we spend a fair bit on the ISP.
We also monitor branch sites, each router at the site branch is a little linux box so they are giving prtg pretty nice independant stats. If a single branch site is down that's not so bad. But a home site being down is essentially all branch sites down. On average each month, home site has about 99.99x% uptime, but our site branches have much less (99%-99.9%).
At the end of each week we want to have a report that would show ping time average/max packet loss, and downtime (where downtime is no response received in some arbritrary amount of time).
Also when our home site is down we want to be alerted promptly that there is a problem.
Any help configuring this is appreciated.
