Nebula Graph 的日志默认在 `/usr/local/nebula/logs/` 下，正常 INFO 级别日志文件为 `nebula-graphd.INFO, nebula-storaged.INFO, nebula-metad.INFO`，报警和错误级别后缀为 `.WARNING` 和 `.ERROR`。

Nebula Graph 使用 [glog](https://github.com/google/glog) 打印日志。glog 没有日志回收的功能，用户可以使用 crontab 设置定期任务回收日志文件，详情请参见 [Glog should delete old log files automatically](https://github.com/google/glog/issues/423)。
Nebula Graph 使用 [glog](https://github.com/google/glog) 打印日志。glog 没有日志回收的功能，用户可以：

- 使用 crontab 设置定期任务回收日志文件，详情请参见 [Glog should delete old log files automatically](https://github.com/google/glog/issues/423)。
- 使用 [logrotate](https://github.com/logrotate/logrotate) 实现日志轮询。使用 logrotate 管理日志前需修改相应 Nebula Graph 服务的配置，将`timestamp_in_logfile_name`参数的值改成`false`。
