Hi. I'm Dennis.
At my DAIR Systems LLC office, I am manage a computer service spread among internet-connected computers. A key management and status tool I use is the computer with the bright screen in the photo below. As such, I am a micro-noc, a scaled down network-operations-center.
The tool has evolved from the time this picture was taken. Click next for a live screenshot of the bright screen in the configuration below taken today April 26, 2018.
