I suspected that our storage appliances were prematurely pulling disks out of their pools because of heavy I/O from triggered maintenance we've been asked to automate. So I built an application that pulls entries from the event consoles in each site, from queries it makes to their APIs. It then correlates various kinds of data, reformats them for general consumption, and produces a CSV.

From this point, I am completely useless. I was able to make some graphs with gnumeric, libre calc, and (after scraping out all the identifying info) Google sheets, but the sad truth is that I'm just really bad at desktop office document apps. I wound up just sending the CSV to my boss so he can make it pretty.
