ELK (or Elasticsearch, Logstash, Kibana) is a set of three technologies by elastic that can be combined to collect and visualize log data. Think of it as rsyslog on steroids and with pretty colors. Ryan and Bailey have both implemented ELK into our personal infrastructures recently, and while it’s pretty simple once your know what

Below is a collection of useful Bash one-liners that we have come across and use semi-often (or at least often enough to not want to lose them). Honestly we mostly made this just in case we need them again and have lost them elsewhere, but hopefully they end up helping some of you as well!

Filebeat is the tool used to forward logs from a client to an ELK server. It can be seen as equivalent to using rsyslog to forward to a syslog server. I’ve recently finished setting up an ELK server at Rob and I’s apartment, and have been setting VM’s that we run to forward their logs

A few quick notes before that actual post: I posted this originally in early 2018 on a different website, but no longer use that site. So I decided that it would make sense to re-upload here with a few edits. There is something called Xen and something called Xen Server. Xen is a virtualization platform

You have probably noticed that network adapters in Linux now follow a naming convention of “enpXsY” or “wlpXsY” instead of “ethX” and “wlanX”. This is generally fine and doesn’t cause much issue. The one downside to the change is that Gentoo and Linux From Scratch VMs running on VMware will have ridiculous names like “eno16777728”.
