This document outlines an agenda and presentation for a workshop on network management and monitoring using Smokeping. The presentation covers topics such as ICMP and ping, the basics of Smokeping, graph details, and a discussion session. Smokeping is introduced as a tool for visualizing network latency over time through interactive graphs. It works by sending ping packets and recording round-trip times to analyze network performance metrics like packet loss and jitter.

Ping
 Widely used to test destination availability
 Measures RTT between source and destination
 Shows packet loss and jitter
 Source sends echo request (ping) and receives echo
reply (pong) from Destination

Introduction to Smokeping
 Best of breed latency visualization
 Interactive graph explorer
 Wide range of latency measurement plugins
 Master/Slave System for distributed measurement
 Highly configurable alerting system
 Live Latency Charts with the most 'interesting' graphs
 Free and OpenSource Software written in Perl written
by Tobi Oetiker, the creator of MRTG and RRDtool

Smokeping Features
 Latency measurement tool
 Visual representation of ICMP delay
 Lots of information in a picture
 Easy to install and configure
 Written in Perl
 Based on RRDTool
 Generate alarms
 Integration with ticketing system

How Smokeping Works
 Sends several test packets (pings) in each round of
measurement
 Makes note of RTT of each ping packet
 Sorts different RTTs and selects the median
 The median value is drawn in the graph
 Other values of RTTs are drawn as lighter shades of gray
(smoke)
 The color of the median line changes according to the
number of packets lost

Graph Interpretation
 All this information together gives an indication of network
health
 Colored horizontal line represents median RTT and the
packet loss (if any)
 The smokes represents jitter, the more scattered smokes, the
more fluctuation in the RTT
