3. Office of Information Technology
Motivation
Measurement Infrastructure typically means WAN monitoring
But problems are LAN and host based
Network Operations
Single point of view
Catastrophic failure is easier to detect
Little quantitative data to troubleshoot performance problems
Office of Information Technology

4. Office of Information Technology
CPR
Campus-wide Network Performance Monitoring and Recovery
50+ hosts on Campus
Collocated with switches in data closets
Multiple views of the network
Especially the users view
Regular tests across campus network

Other Deployments
Local ISPs
Major providers (Level3, Qwest, Charter)
Residential (SpeedFactory, BellSouth, Charter, Cox)
Global collaborations
International focus in strategic plan
Metz, Shanghai
Leverage Global PMP Infrastructure and communicate using emerging standards
Office of Information Technology

8. Deployment Experience
On the whole, very smooth
Control of Network
Firewall
Physical access
Control of satellite server, DNS
Warmly welcomed
Help is on the way
Pass the buck
Office of Information Technology

9. Deployment Experience
Donated hardware
Cheap
Flakey
Scavenging of parts before donation
GAMMON/International deployment faces more of the traditional challenges
Office of Information Technology

10. Office of Information Technology
Toolset
No in-house development of measurement tools.
Original plan also didn’t include much visualization.
Inconvenient to click through numerous graphs
Office of Information Technology

11. Office of Information Technology
Measurements
Currently
Smokeping - roundtrip time and graphs.
Nagios - Services.
Security - nessus and nmap.
Also available
Iperf (bwctl) - TCP throughput only.
Pathchar, traceroute
Coming soon
NDT (central, distributed)
Test bed for tools under development
Office of Information Technology

12. Measurement Experiences
Passive Monitoring of border traffic
Bwctl.sox is outside GT.
OWAMP
NTP
Alleged network problems are often issues with applications
Added application monitoring using Nagios
Information Security
CPR as a platform for other groups, research
Office of Information Technology

13. Office of Information Technology
Analysis
Analysis
Create base-lines for historical comparison
Use multiple view to detect location
Middleware
Alarm system
Plateau detector (AMP), RIPE-TT
How should we react to alarms?
Troubleshooting guide
Office of Information Technology

14. Office of Information Technology
Analysis Experience
Initial design was active monitoring
Integrate with passive tools
Wireless tools, NETI
Provide a platform for localized netflow reports
Initial design was to avoid looking at graphs
Auto detect and alarms
MyCPR
Office of Information Technology

15. Office of Information Technology
MyCPR
Configurable alarms and graphs
Office of Information Technology

16. Office of Information Technology
Case Studies
CPR has helped solve numerous issues
Firewall
Network slowness for file sharing
Dropped sessions
Not everything is a network issue
Office of Information Technology

17. Office of Information Technology
Experiences
Don’t assume anything
If you don’t measure, you don’t know.
Don’t expect people to do what they should
When one door closes, another one opens.
