Can Htop Display Process Uptime on Ubuntu

This article clarifies whether the htop system monitor displays process uptime on Ubuntu systems. It distinguishes between CPU usage time and actual process runtime. Readers will learn the default capabilities of htop and the specific command required to view accurate process uptime.

By default, htop does not display process uptime. The TIME+ column shows total CPU time consumed, not the elapsed time since the process started. While newer versions allow adding an ELAPSED column in setup, the standard interface focuses on resource usage rather than duration.

To view actual process uptime reliably, use the ps command. Run ps -eo pid,etime,cmd in the terminal to list process IDs, elapsed time, and command names. This provides the accurate wall-clock duration without needing to configure system monitor tools.
