Is Kubernetes Monitoring Flawed? - OpenObservability Talks S3E08
Manage episode 353546841 series 3252969
A 3-node Kubernetes cluster with Prometheus will ship around 40k active series by default! Do we really need all that data? The current state of Kubernetes open source monitoring is in need of improvement. High churn rate of pod metrics, proliferation of metrics with low usage, and configuration complexity are some of the issues that need to be addressed.
I discussed this topic with Aliaksandr Valialkin, CTO at VictoriaMetrics and creator of the open source project. We discussed the common problems, as well as directions and best practices to overcome some of these complexities as individuals and as a community. We also discussed VictoriaMetrics open source project and how it addresses some of these challenges.
Aliaksandr a Golang engineer, who likes writing simple and performant code and creating easy-to-use programs. Sometimes these hard-to-match requirements work together, like in the VictoriaMetrics case.
