I keep track of my daily commutes to and from the office. One thing I want to know is how the different days of the week are affecting my travel duration. But when indexing all my commutes into Elasticsearch, I can not (out-of-the-box) create a histogram on the day of the week. My first visualization […]

Smart energy consumption insights with Elasticsearch and Machine Learning
At home we have a Youless device which can be used to measure energy consumption. You have to mount it to your energy meter so it can monitor energy consumption. The device then provides energy consumption data via a RESTful api. We can use this api to index energy consumption data into Elasticsearch every minute […]
Simulating an Elasticsearch Ingest Node pipeline
Indexing document into your cluster can be done in a couple of ways: using Logstash to read your source and send documents to your cluster; using Filebeat to read a log file, send documents to Kafka, let Logstash connect to Kafka and transform the log event and then send those documents to your cluster; using […]
Collecting data from a private LoRaWAN sensor network into Elastic
Introduction to LoRaWAN and ELK Why LoRaWAN, and what makes it different from other types of low power consumption, high range wireless protocols like ZigBee, Z-Wave, etc … ? LoRa is a wireless modulation for long-range, low-power, low-data-rate applications developed by Semtech. The main features of this technology are the big amount of devices that […]
Shield your Kibana dashboards
You work with sensitive data in Elasticsearch indices that you do not want everyone to see in their Kibana dashboards. Like a hospital with patient names. You could give each department their own Elasticsearch cluster in order to prevent all departments to see the patient’s names, for example. But wouldn’t it be great if there […]
Creating an advanced Kibana dashboard using a script
Some time ago, Kibana joined the elasticsearch family. A lot of good things have come out of it. These days Kibana is becoming more advanced. But with more users also come more demands. One of those demands is more advanced dashboards than can be clicked together in the very nice GUI. We want to be […]
Using logstash, elasticsearch and Kibana to monitor your video card – a tutorial
A few weeks ago my colleague Jettro wrote a blog post about an interesting real-life use case for Kibana: using it to graph meta-data of the photos you took. Given that photography is not a hobby of mine I decided to find a use-case for Kibana using something closer to my heart: gaming. This Christmas […]
Use Kibana to analyze your images
If you are reading some technical blogs, maybe about search or data analysis, chances are big you have read about Kibana. You have seen stories about how easy it is to use. Most of the blogging effort deals with getting data into kibana using logstash for instance. Maybe some of you have installed Kibana […]
