What are Icinga 2 and SNMP Exporter?
Icinga 2
Icinga 2 is a modern monitoring system that checks the availability of network resources and notifies users of outages. It is Nagios-compatible, scales across clusters, and pairs with Icinga Web for a polished interface.
- Distributed cluster monitoring
- REST API for automation
- Nagios plugin compatibility
- Modern Icinga Web UI
SNMP Exporter
The SNMP Exporter scrapes SNMP-enabled devices such as switches, routers, and printers and exposes their metrics for Prometheus. A generator builds configurations from MIBs for specific devices.
- Scrapes SNMP devices
- MIB-driven config generator
- Network hardware monitoring
- Prometheus integration
