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)

Node.js and io.js Monitoring | @DevOpsSummit #DevOps #Microservices

Node.js and io.js Monitoring Support By Stefan Thies Node.js and io.js are increasingly being used to run JavaScript on the server side for many types of applications, such as websites, real-time messaging and controllers for small devices with limited resources. For DevOps it is crucial to monitor the whole application stack and Node.js is rapidly becoming an important part of the stack in many organizations. Sematext has historically had a strong support for monitoring big data applications such as Elastic (aka Elasticsearch), Cassandra, Solr, Spark, Hadoop, and HBase, as well... (more)

Open Source Docker Monitoring | @DevOpsSummit #DevOps #Docker #Containers

Open Source Docker Monitoring and Logging By Stefan Thies Pets ⇒ Cattle ⇒ Orchestration Docker is growing by leaps and bounds, and along with it its ecosystem.  Being light, the predominant container deployment involves running just a single app or service inside each container.  Most software products and services are made up of at least several such apps/services.  We all want all our apps/services to be highly available and fault tolerant.  Thus, Docker containers in an organization quickly start popping up like mushrooms after the rain.  They multiply faster than rabbits. Whi... (more)

Solr vs. Elasticsearch — How to Decide? By @Sematext | @DevOpsSummit [#DevOps]

Solr vs. Elasticsearch — How to Decide? By Otis Gospodnetić [Otis is a Lucene, Solr, and Elasticsearch expert and co-author of “Lucene in Action” (1st and 2nd editions).  He is also the founder and CEO of Sematext. See full bio below.] “Solr or Elasticsearch?”…well, at least that is the common question I hear from Sematext’s consulting services clients and prospects.  Which one is better, Solr or Elasticsearch?  Which one is faster?  Which one scales better?  Which one can do X, and Y, and Z?  Which one is easier to manage?  Which one should we use?  Which one do you recommend? ...
