Introduction Icinga Stack Monitoring Availability, Reliability, Observability Log Management ElasticStack, Graylog Automation Director, CfgMgmt-Support, API Metrics and Analytics Graphite, Grafana, InfluxDB, OpenTSDB
Icinga2 Core Scalable infrastructure monitoring icinga.com/docs/icinga2/ Combine high availability clusters with a distributed setup, and you have a best practice scenario for large and complex environments. Monitoring as code with dynamic configurations. Icinga2 Core
Icinga Director Our configuration and orchestration solution icinga.com/docs/director/ The Director aims to be the favorite Icinga config deployment tool. Director is designed for those who want to automate their configuration deployment and those who want to grant their “point & click” users easy access to the configuration. Icinga Director

Product Update
Icinga 2 Our Monitoring Core
01 Stability 03 Namespaces 02 Syntax Highlighting Icinga 2 Latest features from Icinga 2.10 This release adds a dynamic thread connection pool for both, cluster messages and HTTP requests. With the performance boost granted, we’ve also lowered the cluster reconnect interval from 60 to 10 seconds. 2.10 also brings support for namespaces and allows us to keep the “globals” namespace clean. In addition to that, user-defined namespaces are possible and can be imported into the global namespace too Updated the vim syntax highlighting including namespace support. You’ll also recognize that macro strings are now specifically highlighted.

01 Multiple Instances 03 Config Basket 02 Health Check Icinga Director Latest features from Icinga Director 1.6 This used to be a hidden feature in the former version. Deal with multiple Director instances from a single web frontend. Deploy to completely distinct or to the very same Icinga Cluster. The Director Health Check has been a thing since v1.5. The latest version makes it Multi-Instance-aware and reachable from the Director Dashboard. Snapshot a specific Set of Commands, Templates, Import/Sync definitions and much more at any point time. Download, diff and/or restore to the very same or another Director instance. Perfect for Multi-Stage Setups and/or for sharing Configuration Snippets.

Icinga DB
01 Performance 03 Flexibility 02 Schema Icinga DB The replacement for IDO Decoupling Icinga2 from the database backend does not block the core under high load and since all volatile data is stored in Redis, there are by far less updates in the database Way easier to calculate availability data and create business reports on top of the new database schema. Also access on custom variables works in large environments Parts of the future Icinga architecture will rely on Redis as an in memory database
