I have a PC on my network that I want to monitor with a simple periodic ping from a Raspberry Pi. I'm totally new to the RPi and Linux and this seemingly simple project is turning into a massive headache. However, I've made massive progress in installing Nagios PI on the RPi and configuring it to monitor my PC with a periodic ping via NConf. So within the Nagios GUI I can see when my PC is up and down (this took 2 days to get this far). I also setup e-mail on the RPi using sSMTP and I can send e-mails from the command line (this took another long day).
So all I now need to do is get Nagios/NConf to send me an e-mail when it sees my PC is down. Unfortunately, this is where my luck or talent (or both!) have run out. Can anyone help point me in the right direction to get these e-mail notifications working within Nagios/NConf please?
Any ideas greatly appreciated!
