System Monitoring with Check_MK - Part 1: Basics

Five-day training in Check_MK and OMD for beginners

With Check_MK, the setting up of a monitoring system is a breeze, even on large installations. Working with the command line is reduced to a minimum, as WATO provides a powerful graphical configuration interface. With this you do not need to be a Linux expert to implement a monitoring system that easily manages big and complex setups.

Using the Open Monitoring Distribution (OMD) as a basis makes installation and updates run very smoothly, including many popular addons such as NagVis (graphical visualization) and PNP4Nagios. (long-term recording of metrics)

In our basic course System Monitoring with Check_MK, you learn how to set up a professional monitoring system and structure it in a sensible way, to monitor the network, servers, operating systems and applications. You do not need any Linux expertise. All that you need to know, you will learn in the course. For this we follow a very practical approach. First we install a full monitoring environment with OMD, then we address the monitoring of Windows and Linux, network devices and services as well applications step by step. This way you learn how Check_MK operates, how acknowledgements and downtimes work, the difference between passive and active checks, how to configure notifications, how to assign hosts and services to users, and a lot more. Of course you will also learn all about the advantages Check_MK has compared to other systems and what it's users love about it, such as:
  • Automatic discovery and configuration of monitored services
  • The rule-based configuration based on host tags, that is an advantage especially in complex environments
  • Distributed Monitoring (centralized visualization of multiple monitoring servers)
  • The very customizable UI of Check_MK

With the add-on PNP4Nagios we will record and graphically evaluate metrics (e.g. PING times, network load, cpu utilization) over a longer period of time.

With NagVis we create graphical maps and diagrams to represent current system states clearly.
