Performance monitoring is great because it lets you see whether your application is fast or slow, and which parts need speeding up. For Node developers, those “parts” are most often endpoints handling incoming requests. Since the introduction of our performance monitoring offering in July 2020, Node devs have been able to use the Sentry SDK, @sentry/node, to measure the total time it takes to process each request, but we made some significant improvements since then.

Kubernetes namespaces enable you to organize cluster objects, such as applications, devices and variables. Once you define namespaces, you can use this classification to filter, group and manage objects. You can use the same namespaces in duplicated environments and apply policies to specific clusters segments. Kubernetes namespaces are also important for defining roles and ensuring proper access configuration. If you're monitoring Kubernetes, you should try out MetricFire.

Trying to improve the reliability of your Kubernetes deployment? Start with these 5 chaos experiments. Kubernetes 1.20 is scheduled to be released next week, and this version contains a number of amazing enhancements including graceful node shutdown, more visibility into resource requests, and snapshotting volumes. But the change generating the most buzz is the deprecation of Docker as a container runtime.

If you work in monitoring, you know how important it is for the right people to see the right data. Too much irrelevant data creates a flurry of alerts that hinders productivity, and missing out on key data leads to visibility issues. Worst of all is when you get the wrong people tinkering with data that belongs to other teams.
