How We Understand Monitoring
I have a confession to make. I was going to use this blog to wax poetically about the flaw inherent in the well-established notion of the Three Pillars of Observability. I was going to argue that a fourth pillar was badly needed: topological metadata. In other words, without annotating each data stream across the three common data types with a pointer to where that data in the deployment topology was coming from, all you have is a lot of data with no chance of making sense of it.
