NTP Monitoring makes
troubleshooting
easier
When a problem occurs in your network, every minute counts when searching for its cause, especially if the problem is a critical one. The exact time a problem occurs plays an important role in determining its cause. The question: Did any unusual incidents take place at the time the problem occurred?
Therefore, it is important that local system times are always synchronized with the precise timestamp sent by an NTP server
NTP monitoring with PRTG ensures that time synchronization is up and running. This way, ambiguity regarding the classification of errors based on their occurrence at a certain point in time is eliminated, and administrators are able to find causes and solutions more efficiently.
Working with PRTG will give you peace of mind.

This is how NTP monitoring with PRTG works
A high-precision-clock, such as a GPS satellite, is the basis of an NTP server’s timestamp.
The NTP Sensor continuously monitors the response time of an NTP server. It also compares the local system times of your network devices with the NTP server’s precise timestamp.
iWhat is a sensor?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Advantages of
NTP monitoring with PRTG
Identify sources of errors faster
Administrators will spend less time racking their brains and painstakingly comparing the times an error occurred. With the NTP Sensor, they can make sure that time synchronization works fine at all times.
Avoid time differences between systems
Thanks to NTP monitoring, administrators can react quickly if an NTP server is not responding anymore. Differences between local system times and the NTP server timestamp can therefore be avoided and the underlying causes of a problem determined faster
