“We can know one thing: shit’s gonna fail.” Last week we participated in SRECon Americas, held across three days of intensive learning with practitioner talks, hands-on workshops, socializing, and of course vendor booths. Now in its third year, attendees numbered 650 with an additional ~300 from sponsors and organizers.
All businesses today are built on layers of platforms. The app running your business is built on top of the Kubernetes application deployment platform, running on the AWS cloud platform. AWS is built on top of platforms such as the Linux operating system and the Intel X86 processor architecture. Smartly managed, a good product evolves into a platform for users to extract value and for developers to create new products and platforms. We all stand on the shoulders of giants.
If you liked Sematext Docker Agent you’ll love our new agent for Docker monitoring that provides you with even more insight into your Docker, Kubernetes, and Swarm clusters. Because of its power, small footprint, and ease of installation the old Sematext Docker Agent enjoyed high adoption by the Docker DevOps community.
A few weeks have passed since the excitement of the major Grafana 6.0 release during GrafanaCon, which means it’s time for a new Grafana release. Grafana 6.1 iterates on the permissions system to allow for teams to be more self-organizing. It also includes a feature for Prometheus that enables a more exploratory workflow for dashboards.
The grafana-polystat-panel plugin was created to provide a way to roll up multiple metrics and implement flexible drilldowns to other dashboards. This example will focus on creating a panel for Cassandra using real data from Prometheus collected from our Kubernetes clusters. We’ll focus on the basic metrics for CPU/Memory/Disk coming from cAdvisor, but a well-instrumented service will have many metrics that indicate overall health, such as requests per second, error rates, and more.
The ELK Stack (Elasticsearch, Logstash and Kibana) is the weapon of choice for many Kubernetes users looking for an easy and effective way to gain insight into their clusters, pods and containers. The “L” in “ELK” has gradually changed to an “F” reflecting the preference to use Fluentd instead of Logstash and making the “EFK Stack” a more accurate acronym for what has become the de-facto standard for Kubernetes-native logging.
Today we are releasing Graylog v3.0.1 with a few bug fixes. Many thanks to our community for reporting issues and contributing fixes!
Cloud Foundry Application Runtime is an open source platform as a service (PaaS) for running applications and services. Frequently called simply “Cloud Foundry,” the Cloud Foundry Application Runtime (CFAR) is one of many interoperable projects within the Cloud Foundry family. For the purposes of this post, “Cloud Foundry” refers to the Application Runtime.
In the Prometheus 2.7 release, Ganesh Vernekar added a feature called “Subqueries”. Ganesh published an explanation of how to use subqueries over on the Prometheus blog. In this post we’ll share a couple of real-life examples of how we use them at Grafana Labs.
