Testing, documentation, and a bit of programing.

Feel free to ask questions, though we will have time at the end!

The Nagios Family

Originally sprung to life with Nagios Core

Over the last 2-3 years 4 additional programs have joined

Core, XI, Fusion, IM, NNA

Overview

Overview of Nagios Core, XI, and Fusion- Infrastructure Monitoring (Core, XI)- Centralized Management (Fusion)

Overview

Getting Started- Impossible to cover everything on an hour- Live Webinar- Power Up! Talk Shamas Demoret- Focus on Nagios XI

- Everything you can do with Core you can replicate in XI

Nagios Core

Nagios Core

Setup and requirements:- Available in packaged or source versions for many popular distributions such as CentOS, RHEL, and several Debian derivatives such as Ubuntu- Also available as pre-loaded VM's including some popular tools for Core.- Modern 2-4 Core system, 4 Gb of modern memory, 20 Gb hd space or greater.

Nagios Core

Nagios Core is the monitoring and alerting engine that serves as the primary application around which hundreds of Nagios projects are built.

Basic event scheduler, processor, and alert manager for monitored objects

Several back end API's allow for total control over your environment and how it is viewed- Dynamically pull host/service data, as well as status information and plug it into your creations

Nagios Core Cont.

Primary scope of check scheduling, processing, event handling, and alerting

Basic configurations are implemented using flat configuration files which are read into Nagios upon it's start

Rich history- Long life- Helpful, supportive community- Constant community and in house development cycles

Nagios Core, How it Works?

When I use the Core web interface what am I seeing?- Apache served web pages- Checks ran against your devices, results are triggered and sent or received from plugins passively or actively.- Plain text status information is paired with the plugin's exit code and in turn determines your host/service's status, and in doing so, any alerts you have set up are triggered

Interface Introduction

Nagios XI

Installation types and system requirements:- CentOS/RHEL vSphere OVF, Microsoft VM, Vmware VM- Source installation on a minimal install of CentOS/RHEL- Modern 2-4 Core system, 4 Gb of modern memory, 20 Gb hd space or greater.

Nagios XI

Nagios XI uses Nagios Core as it's backend.-Logic and processing remain the same-Checks, event handling and notifications happen in the same fashion-Backwards integration with Nagios Core via flat configuration files

Nagios XI cont.

So what is different?-MySql database handing configurations-Postgres database handling multi-tenancy and users.-Easy to use and navigate frontend-Virtually manageable from the web interface rather than CLI.

Nagios XI cont.

So what does this mean for me?-Efficiency, efficiency, efficiency.-Faster overall reaction time to issues as they arise-Quicker configuration and changing of existing configurations-More customizability see Dashboards / Dashlets, Components, and Configuration Wizards.

Demo Walk-through

http://nagiosxi.demos.nagios.com/

Nagios XI Cont.

Monitor your entire IT infrastructure

Spot problems before they occur

Know immediately when problems arise

Share availability data with stakeholders

Schedule downtime for your systems within the monitoring solution so you are not spammed with notifications when objects go down

Push and pull check results from XI or Core

Event Handlers Made Easy

Use custom scripted event handlers to dynamically work in your environment- Restart services- Automate tasks that would take your team's attention away from watching your infrastructure- Integrate XI with your existing software such as Incident Management programs for ticketing (Nagios IM) etc..

Train Yourself and Your Team

Integrated help system- Embedded tutorial videos and documentation

Online live training services available- http://www.nagios.com/services/training

World class support team- Ensure you are making the correct changes to your environment- Help troubleshoot misconfiguration and implementation

Nagios Fusion

Nagios Fusion, What is it?

Aggregation of your Nagios servers

Centralized control station allowing you to separate your local or world wide teams by what server's they are responsible for.

Drill down into any of your servers from within Fusion to effect changes or view extra details

Global view and management solution for your Nagios installations

Nagios Fusion Cont.

View recent alerts, tactical overviews, and host/service health over all of your Nagios servers
