I saw Charity Majors talk at a conference I attended about a year ago and I've been keeping up with her talks ever since. Each one is brilliant. She's in the monitoring/ops/systems part of our industry which is a space filled with bullshit and buzzwords. Nobody cuts through it with humor and honesty like her.
She's the founder of Honeycomb.io which I've never used, but looks slick, and certainly well-done.
I leave you with a few talks/appearances you may want to watch. I'm not sure these are the good ones. Either way, follow her talks and keep up with her work. It will make you a better engineer.
