How to monitor ISP and be alerted if notifications need Internet?

Here is a Scenario:

1). We want to know when our ISP is down so we could fail over to our secondary ISP 2). What if both Primary and Secondary ISPs are down, how would we know without being notified by a user that is trying to access a service, because PRTG would not be able to notify us due to Internet outage.

What are our options?

1). Can we set up a sensor between a Mobile app and the Core Server and if the connection is lost that could mean ISP issues?

2). Is there a way to set up a Mobile network for Notifications so when ISP is down you get notified through 3G?

3). How about the cloud solution? Is that capable of somehow reporting issues if ping fails to our Public IP?

4). Maybe have a remote probe and if connectivity between remote probe and core probe fails then that means ISP outage?

If all of these are bad ideas or not possible to implement, does PRTG have capabilities to do such notifications?

Thanks in advance, Peter

Hi Peter,

You could also use a HTTP or HTTP Advanced sensor to check the availability of internet sites to draw conclusions about internet connectivity. On the other hand, the "Common SaaS" sensor which is by default on every probe, does just that already by querying the availability of popular services that are usually highly available.

Furthermore you need to be aware that notifications are ONLY processed by the PRTG Core server, so if its internet connection fails, well, notifications requiring an internet connection will fail too. The best thing you can do here would be to have an alternative notification mechanism like using a hardware SMS gateway for example.

Kind regards,

Erhard
