NTP Monitoring makes

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?

The NTP Sensor continuously compares the times of your network devices with the times of a precise NTP server. This allows all network log files to be compared with one another. Ambiguity regarding the classification of errors is eliminated, and administrators are able to find causes and solutions more efficiently.

With PRTG, everyone will work with peace of mind.

This is how NTP monitoring with PRTG works

NTP allows servers to communicate their system times with each other. Because NTP works as a server itself and is not dependent on the local system time, time differences can be compared. The NTP server is a computer that is synchronized by a high-precision clock, such as a GPS satellite.

The NTP Sensor lets you monitor the NTP server. It provides the response time and time difference in comparison with the local time. All local network times can therefore be placed in relation to one another.

Advantages of
NTP monitoring with PRTG

Identify sources of errors faster

Thanks to NTP monitoring, you can place the times in log files in relation to the time when the problem occurred, and therefore determine the underlying cause of a problem more quickly.

Automation for a lighter workload

Administrators will spend less time racking their brains and painstakingly comparing times themselves. With the NTP Sensor, time differences are synchronized automatically in the background.
