## AI overview

A practical guide to monitoring Linux server health through metrics that can reveal resource problems earlier than broad CPU, memory, or disk-usage figures. It discusses iowait, load average, active swap activity, and inode exhaustion, along with warning signs and follow-up investigations.

## Source excerpt

Servers give you warnings before they fail. Most sysadmins performing Linux server monitoring miss them because they're watching the wrong numbers. The metrics that actually matter are one level deeper: iowait instead of CPU percentage, active swap paging instead of memory usage, inode counts instead of just disk space. Continue reading...
