Icinga 2


Icinga 2 - Overview

• Stable version: 2.1.1 (16.9.2014)• Supports all major distributions • Based on C++ and Boost• New configuration format• Compatible with plugins, addons, UIs



Features

• Available Features• Checker, Notifications• Compat (status files, Perfdata, Command Pipe)• Graphite• DB IDO, Livestatus• Cluster

• Simple feature enable/disable• Recurring Downtimes• Scalable for high performance• Embedded health checks• Integrated load-balancing of checks and notifications• Communication using SSL x509 certificates, IPv4/6• Monitoring Plugins 100% compatible



Cluster

• Zone model for distributed setups • Child zones don’t see each other



Cluster

• Event replication, Config Sync & High Availability• Secure communication with SSL x509 • Load-Balancing of Checks & Notifications



Config Differences

• New notification object instead of contacts• Apply services, notifications, dependencies using

• Assign where <condition>• Ignore where <condition>

• Freely definable custom attributes (command macros, apply conditions, ui filter)

• Global constants

• Conditional command arguments

• Icinga Template Library & Plugin Check Commands

• Many, many details



Configuration: Templates, Groups, Apply

Configuration: Commands
