Nagios é uma das soluções opensource de monitoração mais utilizadas do mercado. há uma série de forks, variações do próprio nagios rodando por aí e com novas e melhores funções.

O problema do Nagios sempre foi a customização, por isso a grande quantidade de plugins e guias, passo a passo, para auxiliar neste processo. Lembro-me de alguns

Eis que o pessoal da PacktPublishing, atualmente, a maior editora de livros focados em tecnologia do mercado, acaba de lançar o livro – Nagios Core Administration CookBook.

O livro, em mais de suas 300 páginas, foca em como instalar, configurar e aprimorar o que há de melhor nesta ferramenta de monitoração.

Nagios Core Administration CoobBook focará nos seguintes tópicos:

  • Finding, installing, and writing your own plugins, and learning to reference them as Nagios Core commands for use as host and service checks, including workarounds for making checks through difficult network layouts such as those using Network Address Translation.
  • Managing notifications to send the right kind of notifications to the right people at the right time, and defining contact methods besides simple email messages, including an example of automatic contact rotation.
  • In-depth examples of using the standard set of Nagios Plugins for common network monitoring needs, with discussion of generic methods for monitoring the results of SNMP queries.
  • Remote monitoring methods to handle the situations where Nagios Core cannot directly check a service’s status over the network, to check things such as database servers that only listen locally, or hardware devices with no SNMP OIDs exported.
  • Defining network structure and dependencies in Nagios Core to enable it to perform its notification behavior more intelligently, and allow you to very quickly find the “root” of particular problems; also how to reflect this structure in the network map once defined, and even decorate it.
  • Best practices for managing Nagios Core configuration to make it leaner, more robust, and better suited to programatically generating configuration as specified by other systems.
  • Automating other interactions with Nagios Core, including using passive checks to track tasks being performed both locally and in other parts of the network, or running scripts automatically in response to checks; also includes discussion of developing your own reports or vizualisations using automatically exported data from the system.
