Which command in SPL retrieves the last N number of events?

The command that retrieves the last N number of events in SPL (Search Processing Language) is the tail command. When you use the tail command, you specify how many events you want to retrieve from the end of the result set. This is particularly useful when dealing with large datasets where you want to focus on the most recent information or events that occurred just before a specific point in time.

For instance, if you are analyzing logs and want to see the last 50 entries, you can use the tail command followed by the desired number of events (e.g., ... | tail 50). This will return the last 50 events from your search results.

The other commands mentioned serve different purposes: the head command retrieves the earliest N events from the top, join is used to combine events from different data sources based on a common field, and sort orders events by a specified field, neither of which are designed to directly retrieve the last N events.
