This is a back to basics talk on Linux troubleshooting from a Systems Administrator. There are a ton of Linux commands that can help us troubleshoot a troubled system. Commands like free or top give us a high-level, easy to digest picture of what is going on. What if we wanted to go further? What else is available on the system and what is just an install away?

Let’s explore a few more commands such as iostat, vmstat, pmap, and strace. Let's see what they can tell us about the system as well as where their data comes from.  This presentation take commands that report cpu load, disk io and memory utilization and follow the back to the data we can get out of /proc.  We will also look at strace and how we can use it to dive deeper in to what any particular process may be doing.
