Shout At The Server, by Mark Tomlinson
Overcoming the frustrations of elusive performance issues related to hardware-level faults.
It’s the server fans screaming lonely in the data center. It’s the blood-red alerts in the NOC at night. It’s the tears in your eyes, the perf tests were a lie. It’s the things you cannot see; the rage of hardware-based system instability.” There are times when we are doing performance analysis where the data is leading you to be suspicious about physical hardware issues. Issues that are barely repeatable and seemingly random, but in reality they are hard, cold facts about hardware faults. In this talk I’d like to share a few common patterns using modern observability principles that help you to learn how to make hardware-level issues visible and measurable. We’ll also dig into ideas for remediation of hardware issues even in virtualized platforms.
Even if your head is spinning round and round, you can learn to be strong and laugh and Shout at The Server!
