System Health Check

Periodic system health check delivered via the C4 Control queue.

When to Use

  • •Receiving a control message with "health-check" in the content
  • •The activity monitor enqueues this automatically at regular intervals

Steps

1. Check PM2 Services

bash
pm2 jlist

Parse the JSON output. Every service should have status: "online". Record which services are stopped or errored.

2. Check Disk Space

bash
df -h / /home 2>/dev/null || df -h /

Thresholds:

  • •OK: < 80% used
  • •Warning: 80-90% used
  • •Critical: > 90% used

3. Check Memory

bash
free -m

Thresholds:

  • •OK: < 80% used
  • •Warning: 80-90% used
  • •Critical: > 90% used (or swap > 50% used)

4. Report Results

If all checks pass, log to ~/zylos/logs/health.log:

code
[YYYY-MM-DD HH:MM:SS] Health Check: PM2 X/X online, Disk XX%, Memory XX% - ALL OK

If any issues found, notify whoever is most likely to help:

  1. •Check your memory files for a designated owner or ops person
  2. •If none designated, notify the person you normally work with most
  3. •Use c4-send.js with the appropriate channel and endpoint to send the alert
