Full System Diagnostics
Comprehensive step-by-step diagnostic workflow for claude-mem issues.
Diagnostic Workflow
Run these checks systematically to identify the root cause:
1. Check PM2 Worker Status
First, verify if the worker service is running:
# Check if PM2 is available
which pm2 || echo "PM2 not found in PATH"
# List PM2 processes
pm2 jlist 2>&1
# If pm2 is not found, try the local installation
~/.claude/plugins/marketplaces/thedotmack/node_modules/.bin/pm2 jlist 2>&1
Expected output: JSON array with claude-mem-worker process showing "status": "online"
If worker not running or status is not "online":
cd ~/.claude/plugins/marketplaces/thedotmack/
pm2 start ecosystem.config.cjs
# Or use local pm2:
node_modules/.bin/pm2 start ecosystem.config.cjs
2. Check Worker Service Health
Test if the worker service responds to HTTP requests:
# Default port is 37777
curl -s http://127.0.0.1:37777/health
# Check custom port from settings
PORT=$(cat ~/.claude-mem/settings.json 2>/dev/null | grep CLAUDE_MEM_WORKER_PORT | grep -o '[0-9]\+' || echo "37777")
curl -s http://127.0.0.1:$PORT/health
Expected output: {"status":"ok"}
If connection refused:
- Worker not running → Go back to step 1
- Port conflict → Check what's using the port:
lsof -i :37777 || netstat -tlnp | grep 37777
3. Check Database
Verify the database exists and contains data:
# Check if database file exists
ls -lh ~/.claude-mem/claude-mem.db
# Check database size (should be > 0 bytes)
du -h ~/.claude-mem/claude-mem.db
# Query database for observation count (requires sqlite3)
sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) as observation_count FROM observations;" 2>&1
# Query for session count
sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) as session_count FROM sessions;" 2>&1
# Check recent observations
sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, type, title FROM observations ORDER BY created_at DESC LIMIT 5;" 2>&1
Expected:
- Database file exists (typically 100KB - 10MB+)
- Contains observations and sessions
- Recent observations visible
If database missing or empty:
- New installation - this is normal, database will populate as you work
- After
/clear- sessions are marked complete but not deleted, data should persist - Corrupted database - backup and recreate:
cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup # Worker will recreate on next observation
4. Check Dependencies Installation
Verify all required npm packages are installed:
cd ~/.claude/plugins/marketplaces/thedotmack/
# Check for critical packages
ls node_modules/@anthropic-ai/claude-agent-sdk 2>&1 | head -1
ls node_modules/better-sqlite3 2>&1 | head -1
ls node_modules/express 2>&1 | head -1
ls node_modules/pm2 2>&1 | head -1
Expected: All critical packages present
If dependencies missing:
cd ~/.claude/plugins/marketplaces/thedotmack/
npm install
5. Check Worker Logs
Review recent worker logs for errors:
# View last 50 lines of worker logs
pm2 logs claude-mem-worker --lines 50 --nostream
# Or use local pm2:
cd ~/.claude/plugins/marketplaces/thedotmack/
node_modules/.bin/pm2 logs claude-mem-worker --lines 50 --nostream
# Check for specific errors
pm2 logs claude-mem-worker --lines 100 --nostream | grep -i "error\|exception\|failed"
6. Test Viewer UI
Check if the web viewer is accessible:
# Test viewer endpoint
curl -s http://127.0.0.1:37777/ | head -20
# Test stats endpoint
curl -s http://127.0.0.1:37777/api/stats
Expected:
/returns HTML page with React viewer/api/statsreturns JSON with database counts
7. Check Port Configuration
Verify port settings and availability:
# Check if custom port is configured
cat ~/.claude-mem/settings.json 2>/dev/null
cat ~/.claude/settings.json 2>/dev/null
# Check what's listening on default port
lsof -i :37777 2>&1 || netstat -tlnp 2>&1 | grep 37777
# Test connectivity
nc -zv 127.0.0.1 37777 2>&1
