How must time be synchronized among Dynatrace Managed nodes?

Time synchronization among Dynatrace Managed nodes is crucial for ensuring accurate performance monitoring and logging. Using Network Time Protocol (NTP) for synchronization is the recommended approach because it automatically manages the time settings across all nodes in the environment. This ensures that all components of the Dynatrace Managed setup are operating on the same time reference, which is essential for correlating events and analyzing performance metrics effectively.

Accurate time synchronization is vital for detecting anomalies, analyzing trends, and ensuring that data from different sources can be compared without discrepancies that might arise from time differences. NTP is designed to keep systems in sync to within milliseconds, making it a reliable method for maintaining time consistency.

In contrast, setting the time manually on each node can lead to human error and inconsistencies, especially in distributed environments. Additionally, using a command for time setting does not provide ongoing synchronization, which can lead to drift over time. As for the notion that time synchronization is not required, it overlooks the fundamental role that synchronized time plays in monitoring and data precision. Hence, using NTP is the most effective and efficient method for time synchronization among Dynatrace Managed nodes.
