I would like to know what some options are if either my PRTG server goes down, or the internet connections to my office go down.
I.E, If PRTG cannot contact me via email/push/etc, because of a failure, then what CAN contact me.
I considered that i can get an external service to try to "ping" my office. But to do this correctly i would have to expose my PRTG server, and it does not confirm that my email server, or Proxy is working. (I can get email alerts, and also push alerts, and also http sends to OpsGenie/PagerDuty)
Im thinking of an android phone sitting in the office testing connections to the PRTG server and also the internet, if there is a problem then it will send me a message (via http sends to OpsGenie/PageDuty)
The phone i plan using will be on the local wifi, and a mobile data connection, it also has a battery to handle power issues.
I am thinking about a program like Tasker or Automate, to check to see if i can see certain items on the LAN/WIFI, and I can see the internet (via the LAN/WIFI), If a combo of these failed then send a message to OpsGenie/PageDuty (WAN/Via Mobile Data)
Any thoughts about this? If there any better way to integrate it with PRTG?
