sla_exporter The GitHub repo can be found at: https://github.com/slashdoom/sla_exporter Prometheus exporter for SLA-like metrics. Currently supported are: cURL (http/https), DNS, Ping (ICMP) and TCPing. Similar in a lot of way to Blackbox Exporter, and honestly most people will probably be better served by this. This exporter was desgined to be a bit more basic as it was intended to be run on teleoperated forklifts and the operator stations for them.

Introduction As I’ve mentioned before, this site is built with Hugo as a static site generator. Hugo is great and if you follow the quickstart guide you’ll have a site up and running right quick. However, if you’re like me and you’re developing your own Hugo themes and want to keep your content in a separate repo because you post from multiple devices, etc. then you’ll need something a little more advanced.

Introduction Ionicons is a great icon set created by the Ionic team. Whereas a lot of sets have pulled back from including logos, Ionicons has a large set builtin, it’s MIT licensed, and looks great on web, Android and iOS.
