Many moons ago, monitoring was as simple as spinning up a Nagios instance, or Solarwinds if the business you worked for was a little ‘flush’ with cash. It did exactly what you wanted, allowed you to monitor via SNMP or WMI, and it gave you a simple graphical interface for each ‘node’ that you looked after. Over the last few years though, there is far more to monitoring. Its an area I have an interest in, so I thought I’d document some of what I’ve seen recently.
I spent the early part of my career in IT support maintaining workstations, before eventually moving into infrastructure support, virtualisation and eventually cloud. I’ve never been much of a coder, bar a few basic batch and powershell scripts to help me out along the way and with the DevOps role being used more often than not – its made me sit down and think whether I missed the boat in coding early in my career, or whether there is still a place out there for the ‘old school’ infrastructure guys?
