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。
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，按照本主题中的说明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。您可以使用下面部分中包含的示例
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，如以下示例突出所示的那样：（仅限迁移到 Google Distributed Cloud）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。
apiVersion: apps/v1
kind: Deployment

volumes:

- configMap:

name: logs-config
将 ConfigMap 用于常见应用日志
以下参考 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
