Keeping tabs on your server is very important. Being able to drill down and determine the cause is just as necessary. However, the tools to determine it can seem elusive.
I was happy to discover a new resource in InMotion Hosting and their article “Create server load monitoring bash script“. I immediately set about putting this script on a server that was giving me some issues. It also allowed me to experiment with some server caching and see how well it worked out.
I still find DigitalOcean’s documentation to be among the best, but InMotion Hosting has a nice stash of it as well.
