Azure Icinga 2.5 - Client Connection Guide Scope
Azure Icinga 2.5 - Client Connection Guide Scope The purpose of this document is to provide the steps necessary for connecting a client instance of Icinga 2, version 2.5 or later, to a master node. The steps contained within are sourced from the official Icinga 2 documentation in Section 6, "Distributed Monitoring with Master, Satellites, and Clients" This version of the documentation has been adapted to match the necessary upgrade steps for an instance of the Shadow-Soft Marketplace VHD image. Distributed Monitoring Your Shadow-Soft Marketplace VHD image for Icinga 2 is already configured with a "Master" node. If you have a second Icinga 2 node that you would like to have as a part of your monitoring environment, you can connect the two Icinga 2 daemons together securely using the included icinga2 node wizard commands. This creates an SSL-authenticated tunnel between the daemons over port 5665. This connection will allow configuration to be distributed outward to the satellite, and allow local checks on the satellite node to be executed, then communicated upstream to the master. A master node has no parent node A master node is where you usually install Icinga Web 2. A master node can combine executed checks from child nodes into backends and notifications. A satellite node has a parent node, and may have a child node. A satellite node may execute checks on its own or delegate check execution to child nodes. A satellite node can receive configuration for hosts/services, etc. from the parent node. A satellite node continues to run even if the master node is temporarily unavailable.

Nagios & Icinga Network Monitoring
autoscale: true Nagios & Icinga Philippines Network Operators Group, March 2018 Jonathan Brewer Telco2 Limited New Zealand Network Monitoring: Once you have SNMP data Once you have analysed Log data Once you have service performance data It's time to do something with it! Nagios Nagios is an Internet industry standard for monitoring At times it has been the most popular tool Its job is to monitor hosts & services, and alert on problems Alerting is its forte, it can use email, SMS, or API Handling of issues can be as complex as you need Nagios Home Nagios Hosts Hosts are containers for services If a host is unreachable, so are its services If a host is down, so are its services Nagios treats hosts differently from services! Nagios Hosts Nagios Host Groups Many hosts in a network are identical They can be added to a common group Nagios will behave the same way towards all hosts in a group This saves time & effort in adding hosts to Nagios Nagios Host Groups Nagios Services Nagios pre-defines service templates for many common things DNS, FTP, HTTP, HTTPS, SSH Users can define their own services for special cases For example calling a remote application via SSH Nagios Services Nagios Custom Service Nagios Heirarchy All services in Nagios are children of a host All hosts in Nagios are considered in a heirarchy If a host's parent is unavailable, its children are unreachable This prevents Nagios from alerting on unreachable hosts & services Nagios Heirarchy Nagios Contacts Alerting is what Nagios does best! Contacts the basis of alerting How a contact

For Control Systems at Cern
Evaluation of standard monitoring tools(including log analysis) for control systems at Cern August 2013 Author: Vlad Vintila Supervisor(s): Fernando Varela Rodriguez CERN openlab Summer Student Report 2013 CERN openlab Summer Student Report 2013 Project Specification The goal of this Openlab Summer Student project was to assess the implications and the benefits of integrating two standard IT tools, namely Icinga and Splunkstorm with the existing production setup for monitoring and management of control systems at CERN. Icinga – an open source monitoring software based on Nagios would need to be integrated with an in-house developed WinCC OA application called MOON, that is currently used for monitoring and managing all the components that make up the control systems. Splunkstorm – a data analysis and log management online application would be used stand alone, so it didn’t need integration with other software, only understanding of features and installation procedure. Abstract The aim of this document is to provide insights into installation procedures, key features and functionality and projected implementation effort of Icinga and Splunkstorm IT tools. Focus will be on presenting the most feasible implementation paths that surfaced once both software were well understood.
