Gnocchi – Metric as a Service — Gnocchi 4.2.1.dev96 documentation
Gnocchi – Metric as a Service¶ Gnocchi is an open-source time series database. The problem that Gnocchi solves is the storage and indexing of time series data and resources at a large scale. This is useful in modern cloud platforms which are not only huge but also are dynamic and potentially multi-tenant. Gnocchi takes all of that into account. Gnocchi has been designed to handle large amounts of
Introducing JDBCMetrics
22 May 2013 I've been working with different Java web applications since the late 90's and when there have been performance issues, I would say that 99% of the time, the problem is the database, or rather how it is used. At my last company (Josh) we had a really good connection pool wrapper, that collected data and made us know exactly what happens to the database. But that code isn't Open Source

GitHub - jalkanen/speed4j: Speed4J is a simple performance analysis library for Java.
This is Speed4j, a very simple (but fast) Java performance analysis library. It is designed using Perf4j as a model, but hopefully avoiding the pitfalls inherent in Perf4j's design. Also, Perf4j does not seem to be seeing a lot of development these days... Speed4j has a dependency on SLF4J (see http://slf4j.org), which it uses to log its workings, but no other dependencies. INSTALLING ========== S
Perf4J - Home
Overview Perf4J is a set of utilities for calculating and displaying perfomance statistics for Java code. For developers who are familiar with logging frameworks such as log4j or java.util.logging, an analogy helps to describe Perf4J: How is this relevant to Perf4J? Consider that before good logging frameworks were widely available, developers new to Java would often print debugging statements us

Q-Digest | paper cruncher
Continuing on the same note as the Greenwald-Khanna post, we discuss another novel data structure for order statistics called Q-Digest. Compared to GK, Q-Digest is much simpler, easier to implement and extends to a distributed solution very easily. The data structure was designed with sensor networks in mind, where minimizing radio transmission overhead is of paramount importance. Â It originally a
