2.4. 覆盖日志文件的默认路径

流程

• 要覆盖 nova-compute 服务的默认路径，请在配置文件中添加 NovaComputeLoggingSource 参数的路径：

   NovaComputeLoggingSource:
        tag: openstack.nova.compute
        file: /some/other/path/nova-compute.log

  Copy to Clipboard Toggle word wrap
  注意

  对于每个服务，定义 tag 和 file。其他值默认派生。

  1. 您可以修改特定服务的格式。这会直接传递给 Rsyslog 配置。LoggingDefaultFormat 参数的默认格式是 /(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d+) (?<pid>\d+) (?<priority>\S+) (?<message>.*)$/ 使用以下语法：

     <service_name>LoggingSource:
         tag: <service_name>.tag
         path: <service_name>.path
         format: <service_name>.format

     以下片段是更复杂的转换示例：

      ServiceLoggingSource:
         tag: openstack.Service
         path: /var/log/containers/service/service.log
         format: multiline
         format_firstline: '/^\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d{3} \d+ \S+ \S+ \[(req-\S+ \S+ \S+ \S+ \S+ \S+|-)\]/'
         format1: '/^(?<Timestamp>\S+ \S+) (?<Pid>\d+) (?<log_level>\S+) (?<python_module>\S+) (\[(req-(?<request_id>\S+) (?<user_id>\S+) (?<tenant_id>\S+) (?<domain_id>\S+) (?<user_domain>\S+) (?<project_domain>\S+)|-)\])? (?<Payload>.*)?$/'
