给 Cloud Logging 配置日志记录
本文档介绍如何使用目标工作负载集群上的 ConfigMap 自定义日志记录。
可用日志
默认情况下，Migrate to Containers 会写入来自以下来源的条目：
- 写入所有 Linux 进程的父级
init中stdout的条目。 /var/log/syslog中的内容。
在 Cloud Logging 中，支持的日志文件中的条目将显示以下形式的日志的一行中。在列出日志文件的 ConfigMap 中定义标签。
date time label log-output
以下示例演示了包含 MySQL 条目的表单：
2019-09-22 12:43:08.681193976 +0000 UTC mysql log-output
您可以选择扩展日志转发功能，以传播在迁移的容器中运行的其他进程和应用的日志。
将应用日志转发到 Cloud Logging
如需从通过 Migate for Anthos 迁移的虚拟机上的应用登录 Cloud Logging，您必须做好以下准备：
在目标工作负载集群上创建一个
ConfigMap，用于指定应将其条目写入 Cloud Logging 的文件系统日志文件列表。您可以使用下文中包含的示例
ConfigMap，作为涵盖许多常见日志文件的参考。ConfigMap必须与容器的Deployment或StatefulSet位于同一命名空间中。Deployment或StatefulSet必须引用ConfigMap。如果您要迁移到 Google Distributed Cloud，请在 Google Distributed Cloud 集群上安装 Connect。如需将数据回传到 Cloud Logging，您必须使用 Connect。

使用 ConfigMap 作为常见应用日志
下文中的参考 ConfigMap YAML 涵盖了一系列常见应用日志文件及其应用标签。您可以按原样复制 ConfigMap YAML，或者修改它以移除条目或添加自定义应用日志。
要编辑日志文件列表，请修改 logs: 行下的元素。日志子元素由以下结构组成：
label: - path-with-simple-wildcards
例如：
tomcat:
- /var/log/tomcat*/catalina.out
- /var/log/tomcat*/localhost.*.log
