Full Health Snapshot (run all at once)

Network Speed Test
Download speed (Cloudflare — no install needed)
bash
# 10MB test file from Cloudflare
SPEED=$(curl -s -o /dev/null -w "%{speed_download}" \
"https://speed.cloudflare.com/__down?bytes=10000000" --max-time 15)
echo "Download: $(echo "scale=1; ${SPEED}/1048576" | bc) MB/s"
Latency to key endpoints
bash
for HOST in 1.1.1.1 8.8.8.8 api.anthropic.com api.moonshot.cn; do
RTT=$(curl -s -o /dev/null -w "%{time_connect}s" "https://${HOST}" --max-time 5 2>/dev/null || echo "timeout")
echo "${HOST}: ${RTT}"
done
Upload speed (to your own VPS — internal)
bash
# From container to arifOS MCP endpoint
dd if=/dev/urandom bs=1M count=5 2>/dev/null | \
curl -s -X POST http://arifosmcp:8080/health \
-H "Content-Type: application/octet-stream" \
--data-binary @- -o /dev/null -w "upload: %{speed_upload} B/s\n"
Quick ping test (DNS resolution speed)
bash
for HOST in arifosmcp headless_browser qdrant ollama_engine arifos-postgres; do
TIME=$(curl -sf -o /dev/null -w "%{time_namelookup}+%{time_connect}" http://${HOST} 2>/dev/null || echo "unreachable")

CPU & Process Analysis
bash
# Top CPU consumers
ps aux --sort=-%cpu | head -10
# Top memory consumers
ps aux --sort=-%mem | head -10
# CPU info
nproc && cat /proc/loadavg
# Check if load is high
LOAD=$(cat /proc/loadavg | cut -d' ' -f1)
CORES=$(nproc)
echo "Load: ${LOAD} / ${CORES} cores"
# If load > cores: system under pressure
Disk Analysis
bash
# Overall usage
df -h
# Find disk hogs (top 10 largest dirs)
du -h / --max-depth=3 2>/dev/null | sort -rh | head -10
# Docker-specific disk usage
docker system df
# Ollama model sizes
docker exec ollama_engine du -sh /root/.ollama/models/ 2>/dev/null
# Log sizes
du -sh /opt/arifos/data/openclaw/logs/ /var/log/ 2>/dev/null
Disk Alert Thresholds
bash
USED=$(df / | awk 'NR==2{print $5}' | tr -d '%')
if [ "$USED" -gt 85 ]; then
echo "DISK_CRITICAL: ${USED}% — immediate cleanup required"
echo "Run: docker builder prune -f && docker image prune -f"
elif [ "$USED" -gt 75 ]; then
echo "DISK_WARNING: ${USED}% — monitor closely"
else
echo "DISK_OK: ${USED}%"

RAM Analysis
bash
# Full memory breakdown
free -h
# Per-container memory (sorted)
docker stats --no-stream --format "{{.Name}}: {{.MemUsage}} ({{.MemPerc}})" | sort -t'/' -k1 -rh
# Check if swap is being used (bad sign on this VPS)
free -h | grep Swap
# >100MiB swap used → RAM pressure, check which container to limit
Network Interface Stats
bash
# Bytes in/out since boot
cat /proc/net/dev | awk 'NR>2 {printf "%s: RX=%.1fMB TX=%.1fMB\n", $1, $2/1048576, $10/1048576}' | grep -v "lo:"
# Active connections count
ss -s 2>/dev/null || netstat -s 2>/dev/null | grep "connections" | head -5
OS Info
bash
uname -a
cat /etc/os-release | grep -E "^(NAME|VERSION)="
# CPU model
grep "model name" /proc/cpuinfo | head -1 | cut -d: -f2 | xargs
# VPS host
curl -sf http://169.254.169.254/latest/meta-data/instance-type 2>/dev/null || echo "Not AWS (KVM VPS)"
Auto-Heal Actions (within autonomous authority)
bash
# Disk >80% — safe cleanup
docker builder prune -f
docker image prune -f --filter "dangling=true"
journalctl --vacuum-size=200M 2>/dev/null
# Container OOM-killed — restart it
docker compose -f /mnt/arifos/docker-compose.yml up -d <container_name>
# High load — identify and report (don't kill without F13)
ps aux --sort=-%cpu | head -5
# → Report to Arif before killing unknown processes
