Kubernetes resource usage: How do you manage and monitor it?

18 January 2018 / by Peter Arijs posted in Container monitoring, Kubernetes

When people start looking at running containers in production at scale, they quickly realize they will need an orchestrator such as Kubernetes to efficiently schedule and orchestrate containers on the underlying shared set of physical resources.

The 10 commandments of container-native monitoring

18 December 2017 / by Peter Arijs posted in Container monitoring

Last week, we gave a webinar on container-native monitoring. The purpose of the webinar was to explain what it means to be “container-native” in terms of monitoring, and how this can help you to manage the performance of your container projects. As I was preparing for this webinar, I started making a list of the different elements of container-native monitoring, and I ended up with 10 items, so I decided to call them the “10 commandments”.

Monitoring based on Prometheus endpoints in CoScale

23 August 2017 / by Frederick Ryckbosch posted in Docker, Container monitoring, Prometheus

As discussed in our previous blog post on Prometheus monitoring, we are big fans of the Prometheus endpoints, because they offer a nice and uniform way to expose metrics. In the same blog post, we also discussed some of the limitations around Prometheus and how CoScale can replace Prometheus for Docker monitoring and Kubernetes monitoring. In this blog post, we look in more detail how this can be done.

Prometheus Monitoring: Pros and Cons

24 July 2017 / by Frederick Ryckbosch posted in Container monitoring, Prometheus

Prometheus is a monitoring solution that gathers time-series based numerical data. It is an open-source project started at SoundCloud by ex-Googlers that wanted to monitor a highly dynamical container environment. As they were not satisfied with the traditional monitoring tools, they started working on Prometheus. Google’s monitoring system, Borgmon served as inspiration for Prometheus.
