A great week for monitoring articles, with some unexpected takes and new-to-me tools. I especially enjoyed the post about detecting silent data corruptions at Facebook. 🧠💥

Come hang out with all your fellow Monitoring Weekly readers. I mean, I’m also there, but I’m sure everyone else is way cooler.

A fascinating post from Facebook on using opportunistic (out-of-production) and ripple (in-production) testing to detect silent data corruptions in the wild.
Most of us can take monitoring systems for granted, but others aren’t always so lucky. This article should help you build a strong case for your own observability resources.
A thorough write-up on monitoring, observability, why you need them, and how to leverage both for effective troubleshooting.
How to build a simple but effective dead man’s switch for monitoring your observability stack.
Deploying your Prometheus and Graphite stack with a Helm chart in EKS with an eye towards minimal drift over time.
Kubernetes can be a fantastic tool for a wide variety of use cases, but how do you monitor on-demand environments in a lightweight and repeatable fashion? SIG has a pattern in use for their developers that seems to work well.
I don’t typically link articles that feel “wrong” to me, but this is still a good post from a Shopify engineer thinking about observable systems. I would argue that we need both internal observability (e.g. logs, traces, instrumented metrics) and external performance metrics. What do you think?
Data’s growing at over 20% YoY, but most budgets are not.
Cribl is advocating for an open ecosystem for data with the introduction of an Observability Lake, an open, vendor-neutral place to cheaply store data in open formats. Add this to an observability pipeline to help route logs, metrics, and traces regardless of source, and you can avoid vendor lock-in and take control of all your observability data. Learn more about it from CEO Clint Sharp here. (SPONSORED)
More proof that open source software is eating the world. How one developer uses Grafana with smart home sensors to monitor his aging father’s health and activity. Privacy concerns notwithstanding, it’s great to see humans directly benefiting from these tools.
If you use Kafka in your observability stack, you might be interested in this simple client written in Rust.
A totally unbiased take on the importance of synthetic monitoring in your observability toolkit. All kidding aside, this is a good primer on the different monitoring approaches as you work up the OSI model, and why synthetic monitoring might be suitable for your application.
Good advice for avoiding Java memory leaks and finding the ones already lurking in your code.

Monitorama is returning to Portland, OR this summer. The organizers have recently opened up their CFP for a limited number of speaking slots. Deadline for submissions is March 31, 2022.
