Container Monitoring: Top Docker Metrics to Watch By Stefan Thies Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resources of one or more underlying hosts. It's not uncommon for Docker servers to run thousands of short-term containers (e.g., for batch jobs) while a set of permanent services runs in parallel. Traditional monitoring tools not used to such dynamic environments are not suited for such deployments. On the other hand, s... (more)

Docker Orchestrations Compared | @DevOpsSummit #DevOps #Docker #AI #DX

Docker Orchestrations Compared By Stefan Thies Containerized software is riding a wave of growth, according to latest RightScale survey.  At Sematext we see this growth trend via our Docker monitoring adoption and via Sematext Docker Agent popularity on Docker Hub, where it crossed 1M+ pulls line. This rapid rise of containers now makes Docker the top DevOps tool among those included in RightScale survey. Overall Docker adoption surged to 35 percent, while Kubernetes adoption doubled, going from 7% in 2016 to 14% percent. Although Docker helps with DevOps automation around deve... (more)

Five Steps to #MeteorJS Monitoring | @DevOpsSummit @Sematext #JavaScript

Five Steps to MeteorJS Monitoring By Stefan Thies Meteor is a full-stack JavaScript platform for developing modern web and mobile applications. It includes developer tools, websockets, MongoDB integration, and a package manager.  Atmosphere.js is the Meteor package manager.  Unfortunately, it doesn’t list many Meteor monitoring solutions. Luckily, thanks to the Meteor npm integration, it is possible to use npm packages for monitoring Meteor apps with npm based monitoring solutions, such as SPM for Node.js monitoring.  SPM for Node.js collects key Node.js metrics such as Event Lo...
