Searchlight

Searchlight by AppsCode is a Kubernetes operator for Icinga. If you are running production workloads in Kubernetes, you probably want to be alerted when things go wrong. Icinga periodically runs various checks on a Kubernetes cluster and sends notifications if detects an issue. It also nicely supplements white box monitoring tools like, Prometheus with Blackbox monitoring can catch problems that are otherwise invisible, and also serves as a fallback in case internal systems completely fail. Searchlight is a CRD controller for Kubernetes built around Icinga to address these issues. Searchlight can do the following things for you:

  • Periodically run various checks on a Kubernetes cluster and its nodes or pods.
  • Includes a suite of check commands written specifically for Kubernetes.
  • Searchlight can send notifications via Email, SMS or Chat.
  • Supplements the white box monitoring tools like Prometheus.

Overview

Searchlight dramatically improves the user-focused search capabilities and performance on behalf of various OpenStack cloud services.

It accomplishes this by offloading user search queries from existing API servers and indexing their data into ElasticSearch. ElasticSearch is a search server based on Lucene. It provides a distributed, scalable, near real-time, faceted, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON documents. ElasticSearch is developed and released as open source under the terms of the Apache License. Notable users of ElasticSearch include Wikimedia, StumbleUpon, Mozilla, Quora, Foursquare, Etsy, SoundCloud, GitHub, FDA, CERN, and Stack Exchange.
