Re: RPi 3 intermitent Power problem

Indeed it wasn't crashing in my case (sorry if I caused a confusion in my previous post), but wasn't usable any more. It was throttling so much that the only way I could shut it down correctly was via it serial interface and performing login steps and calling "sudo poweroff" took about 10 minutes......

Re: RPi 3 intermitent Power problem

I have few questions and a couple suggestions: - What your raspberry pi are doing exactly ? - What software are you running on them ? - Are they working at max CPU usage ? If yes, can you cook an egg on them ? Monitor your CPU usage, RAM usage and temperatures to exclude anything related to your use...

Also can run through popen() "systemctl show -p SubState s...

Re: Service(s) Status monitoring with led(s)

Thanks Andyroo. Nagios, I haven't think about it. I had done some tests with it on Raspberry Pi in the past to get more familiar with it, as we have one instance Nagios XI at work. Are you aware of any plug-in to interface it with Raspberry Pi GPIO ? If yes, any recommendation ? I will be honest, I ...

Service(s) Status monitoring with led(s)
