7. Umph..how’s that..?
Monitoring reduces “surprises”
Monitoring provides facts for future planning
Monitoring helps prevent downtime
Monitoring is needed for compliance
How can one not agree that..
• Monitoring is a necessity and not a luxury
9. Monitoring and admins (or geeks like me)
Gain visibility of networks
Become a happy administrator
Be the boss’s pet – Send out reports before he/she
asks you to
Have a life

Gauge effectiveness of investments
Comply to regulatory
Increase visibility to your operations

12. Introduction to Nagios
N.A.G.I.O.S -> Nagios Ain't Gonna Insist On Sainthood
Worlds most deployed open source monitoring solution
Winner of several awards and recognitions
Can monitor *anything*, really..!
13. More on Nagios..
Nagios is a framework
Enterprise grade
• Same class to HPOV, Tivoli, etc..
Supports just about anything you have
It's open source
Highly scalable
Easy to use and customize
Built around largely successful apps such as MRTG, MySQL, Apache and surely,
Linux
14. Common misconceptions
Nagios is open source so it monitors open source products only
Nagios is not easy to deploy/manage
It’s better to use tools from <companyA> to monitor
<companyA> products
Open source means open and exploitable
I need a specialized Nagios ecosystem
