pvcmon Command
Purpose
Allows you to view and log real-time system resource usage in PowerVC for diagnostics and performance monitoring.
Syntax
pvcmon -r {disk|proc|mem|swap|inode} [-n ]Description
The pvcmon command captures and displays system usage data at specific intervals. The pvcmon command supports monitoring of statistics for disk, processes, memory, swap, and inode. The output is displayed on-screen and is also logged to /powervclog/powervc/monitor/pvcmon_monitor.log log file.
Read access to system resource commands is required to run the pvcmon command. The non-root users can safely run the pvcmon command as it does not modify the system state.
