Custom alerts and data visualization let you quickly identify and prevent latency problems and other performance issues.
The telecommunication standardization sector of the International Telecommunication Union (ITU-T) provides many recommendations with regard to quality of service. When it comes to latency, the ITU-T recommends that delays be no more than 125 milliseconds.
We have somewhat stricter requirements than the ITU-T, for we recommend a maximum latency of 100 milliseconds.
The reason: with a lower latency threshold value, you can be notified in due time and intervene before your coworkers notice that something is awry.
Our Paessler PRTG latency monitoring software simultaneously monitors your servers, routers, and switches. It keeps a constant eye on all your QoS parameters. Latency, packet loss, jitter, and the mean opinion score are monitored 24/7/365.
If something goes wrong, you’ll be notified at once so you can immediately recognize and solve the causes of latency issues or other network problems.
PRTG even lets you create reports and gives you the opportunity to compare data over long periods of time.Something powerful
PRTG’s more than 250 preconfigured sensors make it quick and easy to set up your network monitoring – including QoS monitoring and the crucial parameters that go with it.
During installation, PRTG runs its Auto-Discovery feature and automatically creates sensors within your IP address range.

PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!
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:
The Cisco IP SLA sensor monitors Voice over IP (VoIP) network parameters using IP service level agreements (SLA) from Cisco. It can show the following:
The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability. It can show the following:
• Response time
• Packet loss
• Target status
• Minimum and maximum ping time
The WMI Disk Health sensor monitors the health of a physical disk on a Windows system. It can show the following:

Latency is a measurement of the time it takes for a data packet to travel from one point to another. This time is referred to as latency, the round-trip time, or the packet processing time.
By keeping latency spikes to a minimum, you can improve the stability of your network. When latency is too high, problems with VoIP and video conferences are likely to arise. Furthermore, transmission errors can prevent images from loading. Such latency issues are sure to push the capacities of your IT department to the limit.
Do a one-time latency test and use a simple ping query to obtain a one-time calculation of latency. Latency (or the ping time) is equal to the amount of time the query needs to reach its target device. You can also enter a traceroute command into the command line to determine the number of hops.
One-time latency tests provide individual measurements. They can identify specific problems, but they are not useful for comparisons, analyses, or monitoring to maintain ongoing network stability. Thus, you should always choose to permanently monitor the latency in your entire network with a latency checker like PRTG.
Data packets need a certain amount of time to travel from one device to another. This is also true for packets in distributed networks such as a WAN. If a WAN is overloaded, then delays or disruptions may arise. An overloaded WAN can also have a negative impact on the corresponding LAN.
If latency spikes, then data packets are likely to be delayed. They are transmitted more slowly and therefore need longer to reach their destination. PRTG measures the processing time of data packets automatically.
Packet loss can quickly lead to complaints and IT service requests. This is usually due to the dramatic drop in the quality of VoIP or video calls. With packet loss, packets get lost on the way to their destination.
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.
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.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
Bandwidth, servers, virtual environments, websites, VoIP services – PRTG keeps an eye on your entire network.
