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...

Kafka 0.8.2 Monitoring Support By @Sematext | @DevOpsSummit [#DevOps]

Kafka 0.8.2 Monitoring Support SPM Performance Monitoring is the first Apache Kafka monitoring tool to support Kafka 0.8.2.  Here are all the details: Shiny, New Kafka Metrics Kafka 0.8.2 has a pile of new metrics for all three main Kafka components: Producers, Brokers, and Consumers.  Not only does it have a lot of new metrics, the whole metrics part of Kafka has been redone — we worked closely with Kafka developers for several weeks to bring order and structure to all Kafka metrics and make them easy to collect, parse and interpret. We could list all the Kafka metrics you can g... (more)

Solr New Metrics API: Quick look at Solr 6.4

As you know, in Sematext we looooove logs and metrics and we enjoy playing with them on a daily basis. We have our Logsene, which is all about logs and their analysis. We have our SPM which can monitor half of the world when it comes to performance metrics, give you a perfect view of class level performance with transaction tracing, and give you a perfect view of your environment with components view. And that’s not all. Because we enjoy working with metrics, we decided to take a look at the shiny, new Solr metrics API that came out with recently released Solr 6.4. It comes with... (more)
