Nagios Conference 2013 - Sam Lansing - Getting Started With Nagios XI, Core, and Fusion

  1. 1. Getting Started With Nagios XI, Core, and Fusion Presenter: Sam Lansing
  2. 2. Introduction ● Welcome! ● Tech Support at Nagios Enterprises ● Member for 1 ½ years ● Testing, documentation, and a bit of programing. ● Feel free to ask questions, though we will have time at the end!
  3. 3. 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
  4. 4. Overview ● Overview of Nagios Core, XI, and Fusion - Infrastructure Monitoring (Core, XI) - Centralized Management (Fusion)
  5. 5. 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
  6. 6. Nagios Core
  7. 7. 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.
  8. 8. 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
  9. 9. 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
  10. 10. 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
  11. 11. Nagios Core, How it Works Cont.
  12. 12. define host{ host_name linux-server alias Sam's-Linux-Server address 192.168.1.254 parents server-backbone check_command check-host-alive check_interval 5 retry_interval 1 max_check_attempts 5 check_period 24x7 contact_groups router-admins notification_interval 30 notification_period 24x7 notification_options d,u,r }

  14. 14. define command { command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 $ARG1$ $ARG2$ } ● Resources.cfg - $USER1$=/usr/local/nagios/libexec
  15. 15. Interface Introduction
  16. 16. 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.
  17. 17. 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
  18. 18. 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.
  19. 19. 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.”

  22. 22. 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..
