Icinga Configuration For Nginx On Debian Wheezy/Ubuntu 11.10

Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. It is a fork of Nagios. This tutorial explains how to serve the Icinga Web interface from an nginx server on Debian Wheezy/Ubuntu 11.10 (the tutorial might work for Debian Squeeze as well but I didn't test; Squeeze's Icinga version is a lot older than the versions for Wheezy and Ubuntu 11.10, so there might be small differences).

Nagios Installation On Ubuntu 10.04 (Lucid Lynx)

This tutorial shows how to set up Ubuntu Lucid Lynx (10.4) server with the Nagios Monitoring System. Nagios is a powerful, highly configurable monitoring and alarming system, which can monitor a wide variety of systems (network, server, daemons, applications). Monitoring could be done for instance for availability or utilization. The monitoring could be restricted to services which are connectable from the outside (e.g. a webserver on port 80/tcp), or with the help of NRPE (Nagios Remote Plugin Executor) plugins for testing could also be executed remote. We will be installing Nagios, Nagios Plugins, and Postfix with this tutorial. Postfix will be configured to send email via your alternate email server.

System Monitoring With sar And ksar

System Monitoring With sar And ksar

sar is one of the old and famous commandline utilities, which is often overlooked. It provides a wealth of information when you have kind of performance bottlenecks. By itself it only provides lengthy columns of numerical data, kind of hard to interpret. sar exists on most Linux distributions, for example Ubuntu, Debian, CentOS, Gentoo, and is also available on Solaris, AIX, and other commercial Unices. ksar, on the other hand, is a Java based front end for sar's numerical data. It produces friendly graphs which could be exported to .pdf and some other formats.
