How to Measure Jitter
Network jitter is your network's biggest enemy when using unified communications and real-time apps like IP telephony, video conferencing, and virtual desktop infrastructure. To avoid sounding like a robot on video calls, you need to find and fix the source of jitter as soon as possible. In this article, we’re teaching you how to measure jitter in your network using Obkio Network Monitoring.

We'll quickly go over what is jitter in networks. Jitter is a variation in delay - also known as a disruption that occurs while data packets travel across the network.
Obkio’s Network Monitoring Solution continuously measures jitter in your network by sending and monitoring data packets through your network every 500ms using Network Monitoring Agents for the most precise jitter measurements.
Once you’ve set up your Monitoring Agents, they will start measuring metrics like jitter and collecting data, which you can easily analyze on Obkio’s Network Response Time Graph.
Pinpoint jitter anywhere in your network with updates every minute. You can also further drill-down to identify where exactly the jitter is happening, and start troubleshooting.
Unlike most monitoring solutions, Obkio automatically aggregates data over time to be able to display graphs over a large period of time.
With aggregation, Obkio shows you the worst jitter values in the aggregated graph. For example, the amount of jitter displayed over an aggregated period of 1h is the worst median jitter of all the small 1-min periods within that hour.
This is important because only showing you the average amount of jitter on your network may hide network issues.
Let’s say you look at a 30-day period graph and you display the average amount of jitter every 4 hours. The average may be good, but you may have extremely high levels of jitter during one of those hours - which is a huge issue, especially if you’re using real-time applications.
Compared to other monitoring solutions, Obkio shows you the worst jitter measurements in order to highlight network issues, where they’re located and what’s causing them.

To more accurately measure jitter in your network, and be alerted of when it happens, Obkio sends jitter alerts based on historical data and not just static thresholds.
As soon as there’s a deviation in the historical data, and your network is experiencing jitter, Obkio sends you an alert.
Why do we do this? For simplicity.
Network performance is always measured between two points, but depending on where you’re monitoring performance, and even which technology (cable, DSL, fiber) you’re using, the amount of jitter can vary. This would force you to set up different jitter thresholds for every monitoring session - which is a lot of work.
By measuring jitter based on your baseline network performance, Obkio makes the setup much quicker and easier.
Jitter is a network problem that you can hear - mostly because it makes you sound like a robot or laggy. Regardless, it’s still important to continuously measure jitter in your network to determine where it’s coming from and what’s causing it.
The most accurate way to do so is by using a Network Monitoring Software, like Obkio.
Obkio measures jitter using continuous synthetic traffic from Network Monitoring Agents deployed in your most important network locations like offices, data centers and clouds.
The Agents exchange synthetic traffic to measure network metrics between each other. For example, you can measure network jitter between your head office and the AWS cloud, or even between AWS and your data center.
That’s why Obkio offers different types of Monitoring Agents that you can deploy.

As we said above, jitter is one of the core network metrics which gives you an overview of your network performance and can also have a huge impact on the end user experience.
There are many reasons why you should be measuring jitter. Here’s why:
For optimal network performance, it’s important to know how to measure jitter in your network to understand if data is traveling across your network successfully. If it isn’t, Obkio will help you take steps to troubleshoot, optimize, and improve your performance for your end-users.
Measuring jitter also allows you to proactively identify network problems as soon as they appear. Jitter is a big issue when using real-time apps and can greatly degrade the user experience. Any sign of jitter means your network isn’t working properly, and needs to be addressed.
Most importantly, measuring network jitter allows you to compare performance data over time, create a baseline for optimal performance, and see the impact of changes on your network.
