Check_MK is a complex addon for Nagios/Icinga and consists of three subprojects. The check and inventory system Check_MK is a general purpose Nagios plugin for retrieving data. It adopts a new approach for collecting data and obsoletes NRPE, check_by_ssh, NSClient, and check_snmp. It features a significant reduction of CPU use on the Nagios host and automatic inventory of items to be checked, and is especially useful with larger Nagios installations. "MK Livestatus" gives immediate and fast access to live and historic Nagios status data. It's a supported backend for many addons including NagVis, NagiosBP, and Thruk. "Check_MK Multisite" is a feature complete replacement for the Nagios GUI, and uses MK Livestatus as a backend. It is very fast, and supports efficient distributed monitoring.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
openpom is a Web interface based on NDO for Nagios or Icinga. It allows you to view almost everything about Nagios or Icinga in a single page: alert, ack, downtime, comment. You can also interact with Nagios or Icinga through ack, downtime, comment, disable, and reset buttons. You can filter on hosts and services states (such as critical, warning, unknown, ok, or outage). The status popin allows you to display graphs, either the ones from Nagios (trends.cgi) or custom ones based on RRD (such as pnp4nagios).
check_nwc_health is a plugin for the Shinken (or Nagios/Icinga) monitoring system. It is used to check hardware health, environment, interfaces, pools, uptime, etc. of a great range of the most popular network components like switches, routers, firewalls, proxies, load balancers, etc. Currently it can monitor: Cisco IOS, Cisco Nexus, F5 BIG-IP, CheckPoint Firewall1, Juniper NetScreen, HP Procurve, Nortel, Brocade 4100/4900, EMC DS 4700, EMC DS 24, Allied Telesyn, and Blue Coat SG600.
SysopView shows information in a visually attractive way, like computers in movies do. The idea is that it can show information relevant to system administrators non-comprehensible for non-technical personnel, while still looking attractive even if you don't know what is shown. The current version can show nagios status data, webcam streams (mjpeg, jpeg, and video4Linux), and VNC, has a built-in terminal emulator in which regular text applications can be run, can sniff the network (including remotely) and dissect streams and show pictures which are sniffed, can show external bitmaps (from, for example, mrtg and rrdtool), and can scroll text (currently showing output of rssfeeds).
Lilac is a configuration tool for Nagios 3. Its features include enhanced Nagios 3 time period support, multiple template inheritance, host templates able to contain services, dependencies, and escalations, an importer which can import existing Nagios configurations and import from a Fruity installation, an Exporter with Nagios process control, the ability backup existing configuration files, and an auto-discovery tool to quickly add your infrastructure into your Nagios installation.
Nagios 4 iPhone is a Nagios interface for the iPhone. It does not require any modifications on your Nagios servers. The server part of this software collects statistics on several Nagios servers, serves a few static files, and generates a JSON response. The client part handles the display of the data on the iPhone.
Nagios has been around for quite some time, but producing output it can consume is something of a black art. Only the plugin documentation actually explains what all the extra semicolons or extended formatting even mean. This is especially onerous when performance consuming add-ons expect a specific structure before operating properly. The NagAconda package strives to greatly simplify the process of actually generating Nagios output using Python.
