Perfetto
Production-grade client-side tracing, profiling, and analysis
Perfetto is a production-grade tracing platform for Android, Linux, and Chrome that captures extremely detailed information about what a system is doing over time. It’s designed around a low-overhead producer/consumer model: instrumented components (“producers”) write binary events into shared memory buffers and a collector (“service”) reliably streams them to storage. The data model spans kernel and userspace, so you can stitch together CPU scheduling, app lifecycles, binder/IPC hops, GPU work, power and thermal signals, file I/O, heap samples, and more into a single coherent timeline. Perfetto’s ecosystem includes a web-based UI that can load multi-GB traces directly in the browser and an offline “trace processor” that exposes the trace as a queryable SQL-like table schema for deep analysis and automation. It integrates natively with Android (replacing older atrace/Systrace paths) and can sit alongside custom instrumentation in apps or services through its SDKs. -

Prometheus JVM Client
Prometheus instrumentation library for JVM applications
It supports Java, Clojure, Scala, JRuby, and anything else that runs on the JVM. If you use Maven, you can simply reference the assets below. The latest version can be found on in the maven repository for io.prometheus. By default, counters, histograms, and summaries export an additional series suffixed with _created and a value of the unix timestamp for when the metric was created. Building the repository needs Java 11 (The project the project still supports Java 6 and Java versions > 11 dropped support for Java 6 output). We recommend to use an up-to-data Java 8 installation. The project provides the maven wrapper and therefore no local maven installation is needed. To build the repository just call ./mvnw verify. -

Rein
Database constraints made easy for ActiveRecord
Data integrity is a good thing. Constraining the values allowed by your application at the database level, rather than at the application level, is a more robust way of ensuring your data stays sane. Unfortunately, ActiveRecord doesn't encourage (or even allow) you to use database integrity without resorting to hand-crafted SQL. Rein (pronounced "rain") adds a handful of methods to your ActiveRecord migrations so that you can easily tame the data in your database. All methods in the DSL are automatically reversible, so you can take advantage of reversible Rails migrations. -

RxJava works by extending the observer pattern in order to support sequences of data/events. It also allows you to compose sequences together declaratively through added operators, all while abstracting away concerns like low-level threading, thread-safety, concurrent data structures and synchronization. RxJava is commonly used for running simple background computations. It supports Java 6 or higher and languages that are based on JVM such as JRuby, Groovy and Clojure. -
