# python处理systemd journal日志

当systemd逐渐成为Linux主流操作系统服务管理器之后，也带来了全新的journal日志体系。通过systemd journal可以实现复杂而灵活的日志过滤和检查，简化了以往需要通过复杂且不同实现的日志处理编程。

> 通过 Python 结合 systemd journal 来实现高效灵活的日志处理。

> 虚拟化Libvirt的日志处从从0.10.0开始采用了systemd journal（如果`/run/systemd/journal/socket`存在），详细参考[libvirt日志](https://github.com/huataihuang/cloud-atlas-draft/tree/6f3204fffc11cf006abd394631e2598d98b415c3/virtual/libvirt/log/libvirtd_log/README.md)
