| Command | Description |
|---|---|
memwatch status |
Current memory usage with visual bar and breakdown |
memwatch top [n] |
Top N memory-consuming processes (default: 10) |
memwatch watch |
Snapshot memory every 2s for 10 iterations |
memwatch process <pid> |
Memory details for a specific PID (VmRSS, VmSize, PSS, etc.) |
memwatch swap |
Swap usage details with top swap consumers |
memwatch alert <threshold> |
Check if memory usage exceeds threshold % |
memwatch detailed |
Full /proc/meminfo dump |
memwatch compare |

Examples
memwatch status # → usage %, visual bar, total/avail/cached
memwatch top 5 # → top 5 RAM consumers (PID, %MEM, RSS, CMD)
memwatch watch # → 10 snapshots, 2s apart
memwatch process 1234 # → VmSize, VmRSS, VmSwap, PSS, threads
memwatch swap # → swap devices, usage, top swap consumers
memwatch alert 80 # → 🚨 if usage > 80%, ✅ if under
memwatch detailed # → full /proc/meminfo
memwatch compare # → two snapshots 30s apart with delta
Requirements
