Overview

 Comparison of Nagios, Shinken, and Icinga  Performance comparison of common features  Usability  Scalability  Extra feature testing for usability  Scoring procedures

What it is

 Monitoring System  Runs checks  Ability to alert  Track trends  Centralized Interaction  Monitor many devices from one location  View all states

Goals

 Provide an in-depth analysis of the software.

 System load  Network Load  Usability  Complete the project this semester

Setbacks

 Hardware  Limited hardware availability  Bad RAM  Support  OS Licensing  Monitoring software support

Client Setup

 KVM   5 host machines 297 Debian clients  Scripted installation and management  Minimal client installation ○ ○ 64MB RAM 1GB disk space  Windows Clients  3 Windows 7 clients with NSClient++  100 clients for each software suite

Nagios

     Version 3.4.4

Written in C Web Interface  Exfoliation Nagios Open Source  Free to use  Forum Support Nagios XI    User Interface Framework Enterprise Support

Nagios (continued)

 Nagios Version 4  Not yet available  Complete rewrite  Support  Currently unable to receive direct support

Nagios - Thoughts

 Simple  Could use more features  Difficult to configure  Confusing configuration file layout  Would be better with a database as a backend  Stable  Lacks features but works well

Icinga

 Version 1.8.4

 Modular  Written in C  Classic Web  Automated Apache integration  Icinga-cmd group  Apache, Icinga user, etc  Authentication

Icinga(continued)

 Check scripts run locally  Check_by_ssh  Similar to Nagios  Third party plugins/scripts  Embedded perl interpretation  Config changes so far:  Check intervals

Icinga(continued)

 Windows integration  Icinga 2.0

 New Web

Icinga - Thoughts

 Quick  Highly customizable  Easy to install  Not very independent, or a “Fork”  Easy to change the installation (modular)  Third party scripts - simple

Shinken

 Version 1.2.3

 Designed as a Nagios drop in replacement that provides many of the features Nagios lacks by default  Written in Python  Open source  Very modular

Shinken - Thoughts

 Custom built installer  Installs all dependencies, configures the system, and can install additional plug-ins  Configuration  Complex, Nagios with Shinken mixed in  Skonf WebUI Beta  Interface  Looks good, lacks functionality

Conclusion

 Nagios was the best over all  No major downsides, or upsides  Shinken & Icinga tied in second.

 Each strong in some areas, but weak in others  Final score (out of 10)  Nagios: 7.8

 Icinga: 7.1

 Shinken: 7.1
