When you are under pressure, trying to find out why this remote procedure call is timing out, that single log message or prometheus metric can be a lifesaver.

This talk will cover some observability tools we use in production, including prometheus, grafana, ELK, real user metrics, as well as Extended Berkeley Packet Filter (eBPF), which gives xray vision into linux.
