MK Livestatus provides a standard API for accessing Nagios data in various programming languages: Python, Perl and C ++.
The API modules and sample documentation is available for use in these languages and is enough to start testing programs. We must have prior knowledge of Accessing Nagios data with “unixcat” and LQL.

Notice, 12/10/2015. If you don’t need Nagios 4 and you are happy with Nagios 3 version I think the best option today is test and use Check_MK Raw Edition (CRE). This free edition is easy to install and includes all software in this post updated. The only reason to continue with this post in my opinion is that CRE not include Nagios 4 to date.

There are many plugins for Nagios for the purpose of monitoring Oracle, from simple tnsping to monitor listener response to various possibilities to monitor the status of tablespaces, instances, disks,…
When we address the need to use Oracle plugins we will always find two possibilities: locally execution (in Oracle server) by a nagios client/agent (NRPE, NSClient + +,…) or execution from the Nagios server itself. If we opt for latter, it’s required to install an Oracle client on the Nagios server, ideally Oracle Instant Client which is lighter than the full client. Besides this, most plugins are written in Perl, so you need the Perl modules needed for these to work. In this post we are going to talk about the installation and configuration of Oracle Instant Client and usually required Perl modules. Although focused for distributions Redhat / CentOS also mention how to install on Debian type Linux.
