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)

Kafka Poll: Producer and Consumer Client By @Sematext | @DevOpsSummit [#DevOps]

Kafka has become the de-facto standard for handling real-time streams in high-volume, data-intensive applications, and there are certainly a lot of those out there.  We thought it would be valuable to conduct a quick poll to find out which which implementation of Kafka Producers and Consumers people use – specifically, which programming languages do you use to produce and consume Kafka messages? Please tweet this poll and help us spread the word, so we can get a good, statistically significant results.  We’ll publish the results here and via @sematext (follow us!) in a week. NO... (more)

Top Node.js Metrics to Watch | @ThingsExpo #APM #IoT #Nodejs #BigData

The dynamic nature of the language provides many “opportunities” for developers to produce memory leaks, and a single function blocking the event queue can have a huge impact on the overall application performance. Parallel execution of jobs is done using multiple worker processes using the “cluster” functionality to take full advantage of multi-core CPUs – but the master and worker processes belong to a single application, which means that they should be monitored together. Let’... (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...
