Mike Pennacchi is one of the worlds leading experts on pinpointing the causes of network and application performance issues.

Transcript

  • 1. Network Protocol Specialists, LLC Network Troubleshooting Video Series
  • 2. Network Protocol Specialists, LLC Using Open Source Tools to Troubleshoot Your Network SmokePing and Cacti
  • 3. SmokePing and Cacti
    • In this example, we will combine SmokePing and Cacti to show how we can use both tools to drill into a problem
    • Neither one by itself can give us all the answers, but by using them together, we can get a good picture of what is going on
  • 4. SmokePing
    • Looking at the 30 hour view, we see a spike in Ping response times
    • Is this an Internet problem, local problem, remote problem?
  • 5. SmokePing
    • We will drill into the SmokePing graph to find the exact time we were seeing the problem
    • Here it is between 7am and 10am
  • 6. Cacti
    • The next step is to use Cacti to look at our local router to see what was happening at the problem time period
    • Not much….
  • 7. SmokePing
    • Here is the utilization at the remote end
    • This could explain the long ping times, it sure would be nice to know who is using up all of the bandwidth
