Terminal tools are fine. Until they're not.
If you work with remote servers, you know the drill: SSH in, run tail -f, pipe to grep, scroll until your eyes cross. It works for a minute. Then you need to search across rotated logs, or filter by time range, or look at something from three hours ago. Terminal tools hit a wall fast.
Downloading logs first wastes time and disk. Cloud tools want you to ship everything to their platform — agents, sync jobs, the whole enterprise Rube Goldberg machine. You just want to see what's happening on your server.
