Production Pulse Check

Quick health check of the production server after deploy or on demand.

Steps

1. SSH into the droplet and run all checks in parallel:

# PM2 process status
ssh [email protected] "pm2 jlist" 2>/dev/null

# Hit the opportunities endpoint for 2-3 cities.
# Note: /api/weather/opportunities is auth-gated — pass CRON_SECRET extracted
# from the droplet's .env.local as a Bearer token.
ssh [email protected] bash <<'REMOTE'
cd /var/www/kardashev
SECRET=$(grep '^CRON_SECRET=' .env.local | cut -d= -f2-)
AUTH="Authorization: Bearer $SECRET"
for city in NY CHI AUS; do
  echo "--- $city ---"
  curl -s -H "$AUTH" "http://localhost:3000/api/weather/opportunities?city=$city"
  echo
done
REMOTE

# Recent error logs (last 30 lines)
ssh [email protected] "pm2 logs kardashev-web --lines 30 --nostream 2>&1"

# Redis health
ssh [email protected] "redis-cli INFO memory 2>/dev/null | grep -E 'used_memory_human|maxmemory_human|evicted_keys'"

# Check warmup status
ssh [email protected] "redis-cli GET kn:warmup:done"

2. Parse the opportunities responses and report:

   • Per city: success/fail, opportunity count, total markets, cached status
   • If any city returns success: false, flag it prominently

3. Parse PM2 status and report:

   • Process status (online/stopped/errored)
   • Uptime, restarts, memory usage
   • Flag if restart count > 0 since last deploy

4. Scan error logs for:

   • [opportunities] errors (new endpoint issues)
   • Cross-city mismatch warnings
   • Rate limit / circuit breaker trips
   • Any 5xx errors

5. Report Redis health:

   • Memory usage vs max
   • Evicted keys count (should be 0 or very low)
   • Warmup flag present (indicates successful startup)

6. Summarize as a single status table:

| Check              | Status | Details                          |
|--------------------|--------|----------------------------------|
| PM2                | ✓/✗    | online, 45m uptime, 0 restarts   |
| NY opportunities   | ✓/✗    | 14 markets, 2 opps, cached       |
| CHI opportunities  | ✓/✗    | 12 markets, 3 opps               |
| AUS opportunities  | ✓/✗    | 12 markets, 1 opp                |
| Redis              | ✓/✗    | 28MB/512MB, 0 evictions          |
| Warmup             | ✓/✗    | complete                         |
| Recent errors      | ✓/✗    | 2 rate-limit trips (benign)      |

Notes

• Droplet IP: 104.248.223.48
• This is read-only — no mutations, no restarts
• The 0-markets issue during warmup is transient (Kalshi rate limits) and self-heals
• Cross-city mismatch warnings for SF→SFO and PHI→PHIL are known alias issues
• Open-Meteo Solar circuit-breaker trips are benign (solar data, not weather)
