Docker 日志输入插件
此插件使用 Docker Engine API 收集正在运行的 Docker 容器的日志。
此插件仅适用于使用 local、json-file 或 journald 日志驱动程序的容器。请确保 Telegraf 具有访问配置的端点的足够权限。
引入于: Telegraf v1.12.0 标签: containers, logging 操作系统支持: all
全局配置选项
插件支持其他全局和插件配置设置，用于修改指标、标签和字段，创建别名以及配置插件顺序等任务。更多详情请参阅 CONFIGURATION.md。
配置
# Read logging output from the Docker engine
[[inputs.docker_log]]
## Docker Endpoint
## To use TCP, set endpoint = "tcp://[ip]:[port]"
## To use environment variables (ie, docker-machine), set endpoint = "ENV"
# endpoint = "unix:///var/run/docker.sock"
## When true, container logs are read from the beginning; otherwise reading
## begins at the end of the log. If state-persistence is enabled for Telegraf,
## the reading continues at the last previously processed timestamp.
# from_beginning = false
## Timeout for Docker API calls.
# timeout = "5s"
## Containers to include and exclude. Globs accepted.
## Note that an empty array for both will include all containers
# container_name_include = []
# container_name_exclude = []
## Container states to include and exclude. Globs accepted.
## When empty only containers in the "running" state will be captured.
# container_state_include = []
# container_state_exclude = []
## docker labels to include and exclude as tags. Globs accepted.
## Note that an empty array for both will include all labels as tags
# docker_label_include = []
# docker_label_exclude = []
## Set the source tag for the metrics to the container ID hostname, eg first 12 chars
source_tag = false
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false环境配置
当使用 "ENV" 端点时，连接使用 CLI Docker 环境变量 进行配置。
source 标签
如果您有许多同名容器，选择容器可能会很棘手。为了缓解这个问题，您可以将下面的值设置为 true。
source_tag = true这将导致所有数据点都将 source 标签设置为容器 ID 的前 12 个字符。如 docker 所定义，前 12 个字符是未显式设置主机名的容器的常用主机名。
Metrics
- docker_log
- 标签 (tags)
- container_image
- container_version
- container_name
- stream (stdout, stderr, or tty)
- source
- 字段 (fields)
- container_id
- message
- 标签 (tags)
