Challenges

Network troubleshooting is a critical aspect of network engineering that enables organizations to maintain reliable and efficient network infrastructure. It involves identifying and resolving issues that affect the performance, security, and availability of a network. This process can be quite challenging because of network complexity and the intermittent nature of some network issues.

The key to effective troubleshooting is network visibility. Once you have reliable insight into traffic behavior, you can use this information as a troubleshooting base, following a disciplined and consistent process.

Troubleshooting application performance

Profitap IOTA is a valuable tool for troubleshooting application performance and ensuring that your applications are running at peak efficiency. IOTA provides a clear overview of which components may be slowing your applications down.

  • Comprehensive overview of all top applications detected in the network traffic.
  • Full visibility into 3000+ applications and protocols (DNS, HTTP, SSH, Office 365, Skype, Whatsapp, Netflix, etc.).
  • Easy filtering on applications per type, and corresponding bandwidth consumption.
  • Instant insight into users, devices, servers, and applications.
  • Analyze key metrics such as latency, throughput, and packet loss.
  • Quickly identify the root cause of performance issues.

QoS monitoring

Combining historical and real-time network traffic analysis capabilities, IOTA offers comprehensive insight into user experience on the network. With a complete array of monitoring dashboards, the source of performance issues can be quickly isolated throughout the different OSI layers.

  • Diagnose issues the moment they are called in, based on historical data.
  • Optimize network resource allocation with insights into traffic flow and bandwidth utilization.
  • Ensure optimal user experience for business-critical applications.
  • Complete view of detected VoIP sessions with cross-correlation between control and data traffic.
  • MOS scores for quick insight into call quality and user experience.

Protocol analysis

IOTA, working as a hardware-based packet sniffer, or a packet capture tool, offers detailed insight into network protocol performance with a comprehensive set of dashboards and visualizations.

  • Full visibility into 3000+ applications and protocols (DNS, HTTP, SSH, Office 365, Skype, WhatsApp, Netflix, etc.).
  • Quickly filter, sort, search, and export the captured network packets.
  • Get in-depth details about packet statistics, such as client IP, server IP, host names, iRTT, and TCP connection completeness.

Network baselining

Profitap IOTA provides real-time monitoring and historical data analysis of network traffic, giving you instant insights into network behavior over time. With this information, it can be easier to pinpoint the root cause of performance issues. Knowing what’s normal, you can more easily discern erratic patterns because they stand out from the baseline.

  • Investigate IP-based traffic patterns and protocol usage.
  • Track average and peak values for network utilization.
  • Recognize new clients or servers in the network.
  • Baseline used TLS versions per server and evaluate ciphers.

Intermittent issues

By accurately capturing packet data around the clock, it’s possible to analyze data from when the intermittent issue occurred. The capture and analysis capabilities of IOTA allow for root cause analysis of intermittent or sporadic network issues. The ability to filter and focus on the relevant packet data helps quicker issue resolution.

  • High quality network traffic capture.
  • Filter back in time to analyze historical events.
  • Rotating capture buffer ensures data retention for analysis.
  • Increase end-user satisfaction with quick issue identification and troubleshooting.

Capturing actionable network data

Network packets make or break your troubleshooting process. One of the key advantages of network packet capture is the level of detail it provides. The ability to capture all information within a packet, including its source and destination addresses, protocol information, and payload data, allows for a more thorough analysis of network traffic, making it an invaluable tool for troubleshooting network issues.

Packet capture tools like the ProfiShark or IOTA have advanced features such as hardware timestamping and hardware capture filters, delivering high-fidelity capture files for analysis.
