The manual’s “top” section includes a warning: visualization complexity grows as O(V+E). For >500 nodes or >2000 edges, jsvisgms degrades to a force-directed mess. Recommended workarounds:
Instead of showing current usage, this generates a time-lapse JSON file of the top 5 processes over 60 seconds.
Use case: Proving a memory leak to your infrastructure team.
Symptom: Silent data corruption. The "FAULT" column is unique to JSVISGMS.
Remediation: This is often a driver incompatibility. Check the manual page: man jsvisgms-fault-management. jsvisgms manual top
For DevOps engineers, manually watching the top interface is inefficient. JSVISGMS exposes a REST-like API via the manual top socket.
Enable the API:
jsvisgms top --manual --api-port 9090
Query the current top process:
curl http://localhost:9090/api/v1/top | jq '.processes[0]'
Example automation script (Bash):
#!/bin/bash THRESHOLD=90 CURRENT_VRAM=$(curl -s http://localhost:9090/api/v1/top | jq '.processes[0].vram_usage')
if [ "$CURRENT_VRAM" -gt "$THRESHOLD" ]; then echo "VRAM critical. Killing top visualizer." curl -X POST http://localhost:9090/api/v1/kill --data '"vid":"highest"' fi
