Wireshark is a free and open-source tool for analyzing network traffic and packet transfers. Many refer to it as a ‘packet sniffer’. It is available on Windows, Unix and Linux. Wireshark analyzes packet transfers in client-server transactions that are used to monitor network protocols. At its core, Wireshark is about troubleshooting a poor user experience.

In other words, Wireshark is a core component of any professional administrator’s toolkit. The program has gained a reputation as one of the most popular tools for conducting manual packet analysis. The problem with Wireshark is that, if you don’t use enough filters, you can quickly become inundated with irrelevant data. This is where SolarWinds comes in.

Response Time Viewer takes the data acquired from Wireshark and adds filters before exporting the data back into Wireshark. Data obtained from a Wireshark packet capture is broken down even further with deep packet analysis. For the user, this not only increases network transparency but makes it much easier to spot network inefficiency.

What is Deep Packet Analysis?

Before we get to SolarWinds Response Time Viewer itself, it’s important to explain deep packet analysis. Deep packet analysis and deep packet inspection are the names given to a type of data processing that examines the contents of data exchanged through your computer.

Your computer sends information to the network in packets, which have a label identifying their name, where they’re coming from, and where they’re going. A deep packet analysis tool like Response Time Viewer allows you to open up the contents of these packets for further inspection. IT administrators can then use this information to troubleshoot their network infrastructure.

Deep packet Analysis is primarily used to monitor the quality of experience. The most popular deep packet inspection tool on the market is Wireshark. Wireshark offers capture and display filtering alongside complex data screens for data analysis. You can measure network and application response time. Network response time is how long it takes for a packet to transfer from the sender to the receiver. Network latency is dependent on a number of factors such as network routing, serialization delay, and speed of light propagation delay.

SolarWinds Response Time Viewer for Wireshark allows the user to measure these factors and identify how their network can be optimized to improve performance. By using a deep packet analysis tool for quality of experience monitoring, an admin can improve the end user experience. In short, these tools can optimize the performance of an enterprise scale network infrastructure.

SolarWinds Response Time Viewer for Wireshark complements Wireshark because it allows the user to conduct deep packet analysis with much better filters than what Wireshark uses by default. Deep packet analysis, also referred to as deep packet inspection or packet analysis, breaks down transferred packets and assesses any performance problems. Response Time Viewer acts as a network diagnostic tool.

You capture network traffic on Wireshark and export it in a .PCAP file into Response Time Viewer. This can then be analyzed by the user. SolarWinds’ software is very versatile in how it can capture packets and analyze packet transfers. The depth of the platform is surprising as well; SolarWinds Response Time Viewer can detect around 1,200 applications.

Deep packet analysis allows you to identify changes or issues that are affecting application performance. Through SolarWind’s platform, you can judge whether an application is faulty or slow due to network inefficiency. This is incredibly useful for maintaining a diverse enterprise-level IT infrastructure.

Without a doubt, one of SolarWinds biggest selling points is its price. Deep packet analysis is extremely expensive at the enterprise level, but Response Time Viewer can be downloaded for free. The extensive functionality of Response Time Viewer stands up to even the most expensive deployable packet analysis solution.

Enterprises looking for more extensive features can also use SolarWinds Network Performance Monitor to use additional DPI technology and conduct exhaustive packet analysis. Though this isn’t free, its competitive price of $3,000 beats out a lot of competition. This makes it an ideal choice for SMEs and enterprises looking to maximize cost efficiency.

Using SolarWinds Response Time Viewer for Wireshark

In order to use Response Time Viewer for Wireshark, you need to have Wireshark installed. Wireshark can be downloaded for free through their community website. Likewise, Response Time Viewer can be downloaded from the SolarWinds site. The ease of access to these two tools makes them extremely convenient for both new and advanced users.

If you’re looking to download Response Time Viewer, one of the main uses of this software is to determine the cause of slow application response times. SolarWinds makes it easy to import Wireshark data into the Response Time Viewer via a .PCAP file.

Once the data is on Response Time Viewer, you can break it down into a variety of metrics: application response time, network response time, data volume, and transaction volume to monitor fluctuations in performance. These metrics are great for running diagnostics on your local network and virtual cloud-based applications.

For newer users, using SolarWinds Response Time Viewer couldn’t be simpler. You can simply start capturing network packets and export them to SolarWinds. Then just find the captured file and click the Analyze button. This keeps the overall analysis time low so you don’t have to spend ages sifting through menus before getting to the issue at hand.

Once the exported file loads, you can start analyzing the packets via the Response Time Dashboard. If you move your cursor over an application, you’ll raise a small orange box providing a breakdown of network and application response times. This will tell you everything you need to know about what is slowing down an application’s performance.

SolarWinds has embraced exporting files as a two-way street as well. You’ll notice that you can export files back into Wireshark with ease through the use of a filter. You simply highlight the application you want to filter and then click Export. This reduces the amount of time needed to search through packet data. On many other packet analysis tools, this process can be quite time consuming.

In many ways, Response Time Viewer acts as a filter. One of the most common problems with packet analysis tools is that they provide you with too much information. This is problematic because analyzing network packets is impossible if you can’t set aside the noise. SolarWinds Response Time Viewer does a great job of allowing the user to easily identify network packet issues with its simple metrics and search function.

Addressing Slow Application Response Time

As touched on above, SolarWinds’ primary purpose is to run diagnostics on applications with slow response times. On cloud-based servers, Response Time Viewer is a lifesaver in terms of troubleshooting because you don’t need control over an application or server in order to run packet analysis.

Once you pull a Wireshark trace and export it into SolarWinds, you can start to break down the difference between network delay and application delay. The network response time and application response time window is shown in the image below:
