How to Monitor Application Network Traffic in Today’s Hybrid World
Visibility gaps can be a major roadblock to ensuring the performance of critical networks and applications. In fact, 35% of network operations (NetOps) professionals struggle with poor visibility across all fabrics of their network, according to a recent survey. As digital businesses continue to rely more heavily on increasingly complex networks and key applications, blind spots can bring day-to-day operations to a screeching to a halt. Without end-to-end visibility, you can’t adequately monitor application network traffic or troubleshoot business-critical issues, which can lead to downtime incidents, poor end-user experiences and other costly problems.
It can be tough to monitor application network traffic in a world where enterprise IT environments are becoming increasingly hybrid. For instance, just look at the level of complexity that new SD-WAN deployments can introduce when rolled out alongside legacy systems! Luckily, there are ways to gain the visibility your business demands.
Leveraging the Power of Packet Data
Generally speaking, you can solve the vast majority of IT issues using flow data. But the minority of networking issues for which this isn’t the case is often the most challenging to solve. They require a deeper level of analysis and troubleshooting using packet data.
Let’s say an application isn’t performing as intended. There’s an endless list of reasons why this might be happening, but in order to get to the bottom of it quickly, you need to be able to effectively monitor application network traffic down to the packet level.
Some organizations leverage free packet capture and analysis tools such as Wireshark, but if you’re managing a larger, more complex enterprise network you’ll likely need a packet capture and analysis solution like LiveNX that offers features like network mapping, streamlined troubleshooting visualizations and tailored reports. These capabilities will help you to ensure the performance of the network and those business-critical applications.
Achieving Heightened Visibility for Hybrid Networks
When talking about the challenges associated with today’s hybrid networks, introducing a new SD-WAN deployment is one of the first scenarios that come to mind. In order to successfully monitor application network performance and ensure satisfactory application performance during an SD-WAN transition, you need full visibility into your existing system. This will enable you to establish a reference point for current application performance and help to determine which application policies you need to set.
Once the new SD-WAN is running, you’ll also need to tap into real-time performance insights to verify it’s operating as designed. Even though some SD-WAN solutions can provide some level of performance data, you’ll need a unified network performance management and diagnostics solution like LiveNX with integrated flow/packet monitoring in order to examine the complete application path from end to end and fully understand how the system is functioning. The ability to monitor application network traffic in this way will allow you to truly understand where various SD-WAN issues originate, determine how best to mitigate them and identify opportunities to optimize the deployment over the long term.
