Criterium measures the computation time of an expression. It is designed to address some of the pitfalls of benchmarking, and benchmarking on the JVM in particular.
This includes: - statistical processing of multiple evaluations - inclusion of a warm-up period, designed to allow the JIT compiler to optimise its code - purging of gc before testing, to isolate timings from GC state prior to testing - a final forced GC after testing to estimate impact of cleanup on the timing results.
InfluxDB 2.7 is the platform purpose-built to collect, store, process and visualize time series data. Time series data is a sequence of data points indexed in time order. Data points typically consist of successive measurements made from the same source and are used to track changes over time. Examples of time series data include:
- Industrial sensor data
- Server performance metrics
- Heartbeats per minute
- Electrical activity in the brain
- Rainfall measurements
- Stock prices
This multi-part tutorial walks you through writing time series data to InfluxDB 2.7, querying that data, processing and alerting on the data, and then visualizing the data.
An open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.

Housed in a miniature and reflowable package, it integrates a SPAD receiving array, a 940 nm invisible Class1 laser emitter, physical infrared filters, and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options.
Unlike conventional IR sensors, the VL53L1X uses ST’s latest generation ToF technology which allows absolute distance measurement whatever the target color and reflectance.
It is also possible to program the size of the ROI on the receiving array, allowing the sensor FoV to be reduced.
