The foundation of things our Head Geek learned back in the US Air Force basic training are a large part of what's made him successful as a professional today. In this webcast, our Head Geek puts on his drill sergeant's hat and discusses the basics that every network engineer, server chick, network manager, or IT dude should know about managing networks. This is a no-frills webcast where we focus on the fundamentals. Some of the things that we'll cover are:

• Assessing your current capabilities
• Prioritizing your needs
• Baselines
• Fundamental technologies No matter where you are in your career, you don't want to miss this session!

Network Management Fundamentals Network Management Fundamentals Presentation Transcript

  • Introduction  A big “Howdy” from SolarWinds® based in Austin, Texas » Josh Stephens - Head Geek, Monster Blogger, and Constant Tweeter » Allison Barker – Thwackerator (Thwack Moderator)  Today’s Topic: Network Management Fundamentals  Who is SolarWinds? » What we do… » Who are our customers? » The SolarWinds community…
  • Housekeeping  Can you hear me now?  If not, use the WebEx Q&A panel to contact the moderator  How do you win the free stuff?  How do you ask questions?  Will this thing be recorded?
  • Agenda  Introductions  Key terms and definitions  Goals and expectations  Baselining  Super Hero Trivia Questions  Types of network management  Best Practices  SolarWinds Demonstration  Summary and Q&A
  • Before we talk about fundamentals… Some key terms you should know and understand » Network management – for the sake of this webcast, we’re talking about managing/monitoring IT infrastructure to include routers, switches, firewalls, servers, applications, circuits, and etc. » Fault – when something is down or unavailable » Availability – percentage of time stuff is not down and is working – i.e. not in fault status » NMS – Network Management System » Baseline – a measurement of current performance
  • Goals and Expectations Why are you investigating network management? Some common answers… » Don’t have a system in place today » Had an outage that the current system didn’t detect… » Current system is too expensive » Current system doesn’t work » Need to improve network availability » Need to improve network performance
  • Goals and Expectations Some things an NMS won’t help you with… » You don’t know how to configure devices on your network » You have devices or service providers that are unreliable » You need to deploy new applications to your end users » Your boss is unmanageable
  • Baselines – Fundamental #1 “If you don’t know where you started, how will you know how far you’ve come?” Baselining the network is the first step in any successful network management project.
  • Baselines  Some important things to baseline  Availability  Application Performance  Network congestion  User reported issues  Even if you don’t have good baselines  Document your goals  Estimate current performance
  • Super Hero Trivia Question #1 The first 5 correct answers get a free SolarWinds t-shirt!!!  Question – What is Superman’s mother’s name?  Answer – Lara Lor-Van
  • Types of Network Management  Fault  Configuration  Accounting  Performance  Security  F-C-A-P-S
  • Basic Fault Monitoring  Goals: » Stop the phone calls… » React more quickly to outages  Common solutions » Ping tools (many times home grown) » Open source tools » Commercial applications
  • Fault Management Systems – How they work  Fault management systems do these things: » Ping devices (ICMP echo request) for status » Query devices with SNMP to check interface status » Send fault notifications (alerts) via e-mail or SMS » Display network issues on a topology map  Classic examples of fault management tools: » HP OpenView (Enterprise software) » Zenoss (open source) » ipMonitor (SolarWinds)
  • Performance Management  Performance management includes monitoring things like: » Server performance (CPU, memory, disk) » Router performance (CPU, memory, buffers) » Circuit performance (bandwidth utilization, errors) » Analysis of network traffic and congestion  Most user reported faults today are actually performance problems…
  • Performance Management – How it works  Performance management systems: » Use SNMP to query MIBs on devices for information » Run user experience monitors to evaluate end-to- end application performance » Use NetFlow (and other flow protocols) to do traffic analysis  The best NMS do both fault and performance management together, seamlessly
  • Head Geek’s Top 5 Best Practices #5 - Define your business objectives before beginning your network management strategy & deployment #4 - Always baseline the network before you start making changes #3 - Consider the true cost of application ownership #2 - Get professional help if you feel like you’re over your head #1 - Anything is better than doing nothing…
  • Super Hero Trivia Question #2 The first 5 correct answers get a free SolarWinds t-shirt!!!  Question – In Superman: Doomsday, who dies – Superman or Doomsday?  Answer – both
