Monitoring a Kubernetes cluster allows engineers to observe its resource utilization and take action when something goes wrong. This article explores what you should be monitoring and how to go about it with Rancher, Prometheus, and Grafana.
Leveraging Datadog with Rancher gives you a full stack view of your applications running on Kubernetes clusters, wherever they are hosted. Learn more.
Container monitoring environments come in all shapes and sizes. Some are open source while others are commercial. Some are available in the Rancher Catalog while others require manual configuration. Some are general purpose while others are aimed specifically at container environments. Some are hosted in the cloud while others require installation on own cluster hosts. In this post, we take an updated look at 10 container monitoring solutions. This effort builds on earlier work including Ismail Usman’s Comparing 7 Monitoring Options for Docker from 2015 and The Great Container Monitoring Bake Off Meetup in October of 2016.
On July 25th, Luke Marsden from Weaveworks and Bill Maxwell from Rancher Labs led a webinar on ‘A Practical Toolbox to Supercharge Your Kubernetes Cluster’. In the talk they described how you can use Rancher and Weave Cloud to set up, manage and monitor an app in Kubernetes. In this blog, we’ll discuss how and why Weave developed the best-practice RED method for monitoring apps with Prometheus. What is Prometheus Monitoring?
Are you monitoring your containers’ resources in real time? If not, then you’re probably not monitoring as effectively as possible. In a fast-moving, dynamic microservices environment, monitoring data that is even seconds old may no longer be actionable. To prevent disruptions, you need real-time monitoring. In this post, I explain why real-time monitoring of container resources is important, and which types of container metrics you should focus on monitoring in real time.
If you use containers as part of your day-to-day operations, you need to monitor them -- ideally, by using a docker performance monitoring solution that you already have in place, rather than implementing an entirely new tool. Containers are often deployed quickly and at a high volume, and they frequently consume and release system resources at a rapid rate. You need to have some way of measuring container performance, and the impact that container deployment has on your system.
In the previous part of this series, we have seen how to deploy an Elasticsearch Cluster using Rancher Catalog. Now it’s time to make good use of this catalog, right? Introduction As a reminder, Elasticsearch is the cornerstone of the ELK platform (ELK stands for Elasticsearch/Logstash/Kibana). In this article, we’ll deploy the stack using Rancher Catalog, and use it to track tags and brands on Twitter. Tracking hashtags on Twitter can be very useful for measuring the impact of a Twitter-based marketing campaign.

If you are familiar with Logstash, Kibana, Prometheus, Grafana, and friends, this post explains what SPM and Logsene bring to the Rancher users’ table, and how they are different from other monitoring or logging solutions.] Meet Sematext Docker Agent [Sematext Docker Agent] is a modern, Docker-native monitoring and log collection agent.
Monitoring your container-based infrastructure is crucial to ensure good performance, identify issues early and gain the insight necessary to maximize its efficiency. When you are dealing with a large number of often short-lived containers spread over multiple hosts and even data centers, understanding the operational health of your infrastructure implies the need to aggregate performance data from both physical hosts as well as the container cluster running on top of it.
 Chris Crane is VP of Product at Sysdig. [Here at Sysdig we build monitoring and visibility tools, specializing in Docker monitoring and containerized infrastructures. Our open source CLI tool, ][sysdig][, offers universal system visibility into Linux machines along with native support for Docker. And based on the same core technology, ][Sysdig Cloud][ offers the first and only comprehensive monitoring solution built from the ground up for containers and microservices.
