A guide to the InfluxDBMapper and QueryBuilder for Java Part: 2

Previously we setup an influxdb instance running through docker and we also run our first InfluxDBMapper code against an influxdb database. The next step is to execute some queries against influxdb using the QueryBuilder combined with the InfluxDBMapper. Let’s get started and select everything from the table H2OFeetMeasurement. 01 02 03 04 05 06 07 08 09 10 private static ...

It is a reality that we tend to make things harder than they might be when we try to use and connect various databases. Since docker came out things became a lot easier. Most databases like Mongodb, InfluxDB etc come with the binaries needed to spin up the database but also with the clients needed in order to connect. Actually ...

I care about time series for a variety of reasons. With the adoption of agile methodologies, cloud, and DevOps, we are now able to develop faster to release new features. This ...

Kubernetes Monitoring with Heapster, InfluxDB and Grafana

Kubernetes provides detailed insights about resource usage in the cluster. This is enabled by using Heapster, cAdvisor, InfluxDB and Grafana. Heapster is installed as a cluster-wide pod. It gathers monitoring and events data for all pods on each node by talking to the Kubelet. Kubelet itself fetches this data from cAdvisor. This data is persisted in InfluxDB and then visualized using Grafana.       ...

Introducing the ReactiveInflux: non-blocking InfluxDB driver for Scala and Java supporting Apache Spark

I am excited to announce a very first release of ReactiveInflux developed at Pygmalios. InfluxDB missed a non-blocking driver for both Scala and Java. Immutability, testability and extensibility are key features of ReactiveInflux. Comming with a support for Apache Spark it is the weapon of choice. https://github.com/pygmalios/reactiveinflux It internally uses Play Framework WS API which is a rich asynchronous HTTP ...
