2. Nick Rowlett – Sparta Area School District Kevin Capwell – School District of Onalaska

3. So you want to monitor your network… Know about an event before the phone rings Keep tabs on critical processes Graph important metrics Visualize trends Keep you in control of your environment

4. What’s that? No money? Commercial Supported Well-developed interface Get started quickly Costs Money – possibly A LOT Open Source (or otherwise Free) Community-driven Time-tested Outdated programming Ongoing time-sink

5. What to know Most open source monitoring systems run on Linux Some are available as a pre-configured VM Each one looks GREAT on the product website You will probably spend way too much time configuring it Most of the open systems are a gateway to a paid system

6. What features are important? What OS does it run on? Does it come as a preconfigured VM? Dashboard Agentless host monitoring (and for which host OS’s) Ease of configuration Pretty interface / graphs / charts LDAP or AD integrated login Device auto-discovery Service monitoring, hardware monitoring

7. The Contenders Open SourceKinda Free

8. Nagios Defacto standard? Difficult setup (until you get used to it) Text-based config files Rock-solid back end No dashboard Variety of front-ends available Can monitor almost anything http://exchange.nagios.org Performance graphing not native but can integrate

9. Icinga Nagios fork https://wiki.icinga.org Slick AJAX interface Still need to know text-based config Comes as a VM Graphing & mapping are not native functions Integrated mobile interface Custom, shareable dashboards

10. OpenNM S Automated discovery Event management w/ traps Mobile client available Runs on Linux/OSX SNMP traps, Syslog Integrated performance graphing RSS integration Interface is in Java (AJAX dashboard)

11. Zenoss Installs on Linux Integrated graphing & mapping Agentless monitoring Configuration workflow is unintuitive (until you get used to it) Community-submitted configuration plugins (ZenPacks) Configurable dashboard Hardware monitoring via ZenPacks Resource hog

12. Zabbix Monitors everything including web services Performance graphing Hardware monitoring Event management No agentless Windows monitoring via WMI Autodiscovery of devices Custom ‘screens’ and ‘slideshows’ for easy visual monitoring

13. Cacti Arguably the prettiest graphs of any system Individual graphs can be used in other web apps or dashboards Excellent performance monitor Not a great hardware / system monitor Runs on Linux or Windows w/ PHP

14. Opsview Built on Nagios 4 Core Application, network, virtualiziation monitoring Mobile app Dashboard, Autodiscovery, Reports, SNMP traps all require Commercial subscription

15. Spicework s All-in-one helpdesk, inventory, purchasing, monitoring & management Crazy easy to setup Runs on Windows Not very granular Can graph performance data, but not too detailed Uses targeted IT-specific ads Great for quick/easy Not great for large/granular

16. Hyperic VMware product Optimized for vSphere Application & Systems monitoring Autodiscovery Nagios integration Agent-based Reports, dashboards, remote agent install, etc. require Enteprise subscription

17. PRTG Freeware edition limited to 10 sensors Smartphone apps available Beautiful graphs Easy setup autodiscovery Dashboards & maps Priced per ‘sensor’ – can get expensive http://www.paessler.com/tools for free SNMP, MIB, NetFlow, WMI, etc. testing tools http://www.paessler.com/tools

18. How to get started Download this presentation from http://www.brainstormk20.com/ Clear your calendar Lock your door, phone on DND Caffeine Use Pre-configured VMs to demo Use a VM snapshot or template of CentOS 6
