Procmon

Watch and control running processes in real time. Use when scanning active PIDs, monitoring resource spikes, reporting trees, alerting on crashes.

Process monitor: list, filter, and watch processes, find zombies, identify CPU/memory hogs, count by state, and log process stats.

Commands

Command	Description
procmon list [filter]	List processes (optionally filter by name)
procmon watch <name>	Monitor a named process (5 snapshots, 2s interval)
procmon zombie	Find zombie processes with parent info
procmon heavy	Show top 10 CPU and top 10 memory processes
procmon count	Count processes by state (running, sleeping, zombie, etc.)
procmon log <name>	Log matching process stats to ~/.procmon/<name>.log
procmon tree [pid]	Show process tree (full or rooted at PID)
procmon ports	Show processes listening on network ports
procmon version	Show version

Examples

procmon list               # → top 25 processes by CPU
procmon list nginx         # → filter for nginx processes
procmon watch sshd         # → 5 snapshots of sshd, 2s apart
procmon zombie             # → find zombie processes
procmon heavy              # → top 10 by CPU + top 10 by memory
procmon count              # → process state breakdown
procmon log node           # → log node process stats to file
procmon tree               # → full process tree
procmon tree 1             # → tree rooted at PID 1
procmon ports              # → listening ports with PIDs

Requirements

• ps (standard)
• pstree (optional, for tree view)
• ss or netstat (optional, for port listing)
