This question https://serverfault.com/questions/590163/monitoring-server-statistics
Is being marked as a duplicate of
https://serverfault.com/questions/44/what-tool-do-you-use-to-monitor-your-servers

The latter question is a locked offtopic "historically significant" question.

Should we be using those to close as duplicates?  Should that old question even still exist?  It is quite out of date, which is the reason product recommendations are offtopic.  Pointing someone at that question isn't likely to help them very much, and may even confuse them further.

What should we be doing with these questions?
