Why is time synchronization important in an NPM environment and how do you configure it?

• A. Accurate time stamps are essential for correlation; configure NTP on the Orion server and ensure all monitored devices and pollers use reliable time sources.
• B. Time synchronization is optional and does not affect data correlation; disable NTP for performance.
• C. Only the monitored devices need time synchronization; Orion's time can be ignored.
• D. Use a local time source on each device and do not synchronize with a central NTP.

Answer: (A)

Time synchronization ensures all clocks in the monitoring environment share the same reference, which is essential for correctly ordering events and correlating data from multiple devices. In an NPM setup, the Orion server collects data from many devices and pollers; if some devices drift, event timestamps and alerts can misalign, making it hard to diagnose issues or match related events. The best approach is to configure NTP on the Orion server to pull time from reliable external time sources and ensure every monitored device and poller uses those same sources. With consistent time, logs, traps, performance data, and alerts line up, enabling accurate correlation, troubleshooting, and reporting. Avoid having devices use local or disparate time sources, or treating Orion time as independent, because that introduces drift and confusion. So the recommended configuration is to set up NTP on the Orion server and enforce reliable time sources across the entire monitored environment.
