It’s been a busy year in the world of Prometheus. Some of the 2020 highlights include a new agent; the addition of some great new features; new ways to reduce memory usage and have a faster restart time; and a fresh look at many old decisions and consensus positions.

With the holidays upon us around the world, some folks here at Sysdig decided to take a technological approach to holiday cooking. How, you ask? By adding a little PromQL to the mix. A home kitchen during the holidays can be a very frenetic place. There are often many, many dishes being prepared at the same time and cooked in sequence. Some are short and easy, others can take several hours. It’s inevitable that a dish will get missed, or a step forgotten.

It’s that most wonderful time of year! Even though it’s been extra challenging for everyone, we can still take a breath, reflect on lessons learned, and look to fill our proverbial cups with knowledge to take into the New Year. We thought we’d revisit a few of our most popular Automation and AIOps resources from 2020.

A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP.

However, one thing that stood out to us is how many aspects of optimization Gartner described as very difficult — which CloudZero can help make easier.

OpenTelemetry has evolved so much since the 2019 KubeCon North America in San Diego, where I live-demoed OpenTelemetry on the keynote stage and highlighted our alpha to the world. We’re excited to be entering general availability of our Collector and Tracing SDKs soon. While I missed the energy from the packed crowd of over 10,000 technologists cheering me on, it was wonderful that this year’s event was more accessible than ever to a worldwide audience.

Many users need their Elasticsearch clusters to always be available. And a lot of these same users also want to upgrade their Elasticsearch environment when a new version is released, so they can take advantage of all the new features and functionality. The result is that admins end up upgrading the Elasticsearch engine while it is operating at full capacity in production. Sound too good to be true?
