headscale_nodes_total- 总节点数headscale_users_total- 总用户数headscale_requests_total- 请求总数headscale_request_duration_seconds- 请求延迟
故障排除
常见问题
-
端口冲突
netstat -tulpn | grep :8080 -
权限问题
chmod -R 755 ./headscale -
数据库锁死
sqlite3 /var/lib/headscale/db.sqlite "PRAGMA integrity_check;"
日志分析
启用调试日志：
log:
level: debug
format: json
查看详细日志：
docker logs -f headscale --tail 100

扩展方案
高可用部署
对于生产环境，建议采用多副本部署：
