Which command helps you to monitor system logs in real-time?

The command that helps you monitor system logs in real-time is commonly referred to as "monitor." This command allows network administrators to observe log messages as they are generated, providing immediate insight into system events and activities as they occur. This real-time monitoring capability is crucial for troubleshooting and ensuring the network's health, as it enables an immediate response to issues as they arise.

The other options do not provide real-time monitoring. For instance, "show log messages" typically generates a snapshot of log messages rather than continuous monitoring. While "view logs" may allow access to logs, it generally does not facilitate real-time observation of log entries. The term "monitor log" is more specific and might imply checking logs, but it does not convey the broad capability that the “monitor” command has in tracking real-time updates. Thus, "monitor" stands out as the appropriate command for active log observation.
