Visit our documentation site @ https://expediadotcom.github.io/haystack/ Overview Haystack is an Expedia-backed open source project to facilitate detection and remediation of problems with enterprise-level web services and websites. The Problem Modern websites rely on dozens or even hundreds of services to function. These services are often spread across many platforms, data centers, and teams. Each service logs information of various kinds: Telemetry data with tags or key/value pairs associated with the event Request/response logs (the XML, JSON, etc. sent to and received from the service) Application logs (typically errors logged via log4j or a similar system) Metrics With so much information spread across many different places, it can be challenging and time consuming to figure out where to look for the cause of a failure or slowdown. The Solution Haystack uses tracing data from a central store to help you locate the source of the problem -- to drill down to the precise part of a service transaction where failures or latency are occurring -- and find the proverbial \"needle in a haystack\". Once you know specifically where the problem is happening, it's much easier to identify the appropriate diagnostic data, understand the data, find the problem, and fix it. Infrastructure The Haystack system includes an easy-to-use \"one click\" deployment mechanism, based on Kubernetes, that deploys a working development envir","default_branch":null,"files":null,"tree":[],"storefront":"/r/ExpediaDotCom","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/ExpediaDotCom/haystack/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
