How does PAESSLER recommend setting up a multi-site PRTG monitoring environment with alerting? I have about 20 sites each with about 2K sensors. The current setup is central server, the rest remote probes.
This seems to case some issues with logging since all logs go back to the main site. Also alerting can only be set up from the main server. Example: if remote site's VPN/MPLS goes down to the main site, PRTG considers ALL sensors offline or in an error state because the link is down. However, the site is fully functional minus the tunnel or that specific sensor. Also, the admins of the remote site will get hundreds of emails about each sensor/device when the link returns since, I assume, emails are queued to deliver and only do so when PRTG connects back to the main site.
What is the recommended setup, or how should this environment be setup, so each site can alert on their own sensors, and each remote site does not have to go to the main site to send email alerts? In the above example if the link breaks, PRTG does not send hundreds of emails about everything being down at that site, but only the link between sites.
