Site Reliability Engineering (SRE) is a subset of web development that uses elements of software engineering, IT infrastructure, and operations [1] to assist with reliability. SRE is similar to DevOps as both aim to improve the reliability and availability of systems.
[1] [2] To improve observability, software engineers use a wide range of logging and tracing techniques to gather telemetry information, and tools to analyze and use it. Observability is foundational to site reliability engineering, as it is the first step in triaging a service outage. One of the goals of observability is to minimize the amount ...
Dynatrace, Inc. is a global technology company that provides a software observability platform based on artificial intelligence (AI) and automation.Dynatrace technologies are used to monitor, analyze, and optimize application performance, software development and security practices, IT infrastructure, and user experience for businesses and government agencies throughout the world.
Datadog was founded in New York City in 2010 [3] by Olivier Pomel [4] and Alexis Lê-Quôc, [5] who met while working at Wireless Generation.After Wireless Generation was acquired by NewsCorp, the two set out to create a product that would reduce the friction they experienced between developer and systems administration teams, who were often working at cross-purposes.
His tools are included in multiple operating systems and products, and are in use by companies worldwide. He pioneered eBPF as an observability technology, [7] including authoring many advanced eBPF tracing tools to provide unique insights into system behavior. As a kernel engineer, he developed the ZFS L2ARC: A pioneering file system ...
Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals. The concept of observability was introduced by the Hungarian-American engineer Rudolf E. Kálmán for linear dynamic systems.

A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
