Send Metrics Not Logs

Voice of the DBA

This is part of a series on observability, a concept taking hold in modern software engineering.

One of the interesting things I saw in an engineering presentation on Observability from Chik-Fil-A was that they are sometimes bandwidth-constrained at remote sites. In an early version of their platform, they sent logs back to HQ, and their logs used all the available bandwidth, so they were unable to process credit card transactions.

While most of us don't deal with lots of remote offices sending data back to a central data warehouse, we do often work in distributed environments, and we may send data to/from a cloud or even employees' remote offices. Or maybe we send a lot of data between components. Bandwidth is very good in many parts of the world, but it isn't infinite.
