One of my clients asked me on how go get insights for Jitter on the path. Troubleshooting, Monitoring, Service Assurance or any other reporting functionality requires data collection. On one hand, monitoring active traffic will provide observations during the interval and report on experience. The “line” quality on the other hand is often measured by synthetic transactions, which can be done with several vendors’ hardware.
