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 developing, building, packaging, and deploying, container orchestration tools such as Kubernetes, Google GKE, Docker Swarm, Amazon ECS, are still in early phases of adoption.  We recently conducted a Twitter Poll asking: What container orchestration tool do you use today? - Sematext Group, Inc. ...

Top @Docker Metrics | @DevOpsSummit #DevOps #APM #AI #CD #Monitoring

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 unde... (more)

Elasticsearch Monitoring By @Sematext | @DevOpsSummit [#DevOps]

While many SPM Performance Monitoring users quickly see the benefits of SPM and adopt it in their organizations for monitoring — not just for Elasticsearch, but for their complete application stack — some Elasticsearch users evaluate SPM and compare it to Marvel from Elasticsearch.  We’ve been asked about SPM vs. Marvel enough times that we decided to put together this focused comparison to show some of the key differences and help individuals and organizations pick the right tool for their needs. Marvel is a relatively young product that provides a detailed visualization of Ela... (more)

Solr Redis Plugin Use Cases By @Sematext | @DevOpsSummit [#DevOps]

Solr Redis Plugin Use Cases and Performance Tests The Solr Redis Plugin is an extension for Solr that provides a query parser that uses data stored in Redis. It is open-sourced on Github by Sematext. This tool is basically a QParserPlugin that establishes a connection to Redis and takes data stored in SET, ZRANGE and other Redis data structures in order to build a query. Data fetched from Redis is used in RedisQParser and is responsible for building a query. Moreover, this plugin provides a highlighter extension which can be used to highlight parts of aliased Solr Redis queries ... (more)
