QoS (Quality of Service) Round Trip

The QoS (Quality of Service) Round Trip sensor monitors parameters regarding the quality of a network connection between two probes. It can show the following:

  • Average, minimum, and maximum jitter
  • Average, minimum, and maximum packet delay variation
  • Average, minimum, and maximum round trip time (RTT)
  • Corrupted, duplicated, lost, and out-of-sequence packets
  • The MOS
(Quality of Service) Round Trip

PRODUCT OVERVIEW

”Adopting PRTG has been like going from being in the dark to being in the light. Before, we had limited visibility into what was happening in the infrastructure and in the network. Now, however, thanks to the comprehensive dashboard and real-time notifications, we receive constant updates on the status of facilities and services, and our way of working has gone from passive to proactive.”

Network Analyzer: FAQ

 

What is a network analyzer?

In IT, the network analyzer is a tool that records and analyzes the traffic on your network. PRTG can monitor several types of wired and wireless networks, including WiFi networks.

How does a network analyzer work?

A network analyzer breaks down traffic by different parameters and presents data flows as diagrams or tables. PRTG helps you break down traffic by connection, protocol, and IP address to identify the top talkers in your network. This helps identify and solve problems in your IT environment.

Why is network analysis important?

Network analysis keeps your IT environment running faster, with better performance, higher security, faster issue resolution, and less downtime. In turn, this creates a better use experience and helps ensure business continuity.

What types of data can a network analyzer capture?

A network analyzer looks at a wide range of data that travels across a network. This includes:

  • Packet data
  • Bandwidth usage
  • Traffic flow data
  • Latency and response times
  • Error rates and packet loss
  • Device and interface statistics
  • Application layer data
  • Security events
  • User activity
  • Traceroute diagnostics
  • DNS queries
Can a network analyzer help with network security?

Yes! Network analysis plays a large role in security. A network analyzer is always on, so it monitors 24/7/365. Ever vigilant, this guard dog safeguards your network through traffic monitoring, intrusion detection, bandwidth and resource usage monitoring, user activity monitoring, real-time alerts, and more. In the event of a security breach, network analysis becomes your forensic analysis tool for locating and wiping out the offender.

What protocols does PRTG's network analyzer support?

Monitor your network via SNMP, flow protocols (NetFlow, jFlow, sFlow, IPFIX), SSH, WMI, or ping. PRTG also supports Industrial IT & OT technologies, such as OPC UA, MQTT, or Modbus. Use the powerful PRTG API for custom integrations (for example, via Python, PowerShell, or REST).

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
