A system administrator has noticed that a server's time is not in sync with its designated time source. They need to verify the current synchronization status and performance of the server's timekeeping. Which command should they use?
Use chronyc tracking to view key synchronization metrics such as current system time offset, last offset, frequency, root delay, and dispersion. These values show whether the local clock is in sync and how well it is being disciplined.
chronyc sources lists each configured or discovered time source and its reachability, but it does not summarize the overall state of the local clock.
chronyc sourcestats reports statistical data (frequency drift, standard deviation, etc.) for each source, which is useful for trend analysis rather than a quick status check.
chronyc add server <address> (shown here without parameters) adds a new NTP server dynamically; it does not display synchronization status.
Therefore, chronyc tracking is the appropriate command for quickly confirming the server's current synchronization status and performance.
