TCP & TLS

tcp 输出插件将记录发送到远程 TCP 服务器。payload 可以根据需要以不同的方式格式化。

Configuration Parameters

Key	Description	default
Host	Fluent Bit 或 Fluentd 监听转发消息的主机	127.0.0.1
Port	目标主机的 TCP 端口	5170
Format	指定输出的数据格式。支持的格式是 msgpack,json,json_lines,json\_stream_.	msgpack
json_date_key	在输出中指定日期字段的名称	date
json_date_format	指定日期格式。支持的格式为 double,iso8601(如: 2018-05-30T09:39:52.000681Z)	double

TLS Configuration Parameters

以下参数可用于配置通过 TLS 加密的安全连接:

Key	Description	Default
tls	是否启用 TLS 连接	Off
tls.verify	是否强制证书认证	On
tls.debug	设置 TLS 调试级别。接受如下参数. 0 (No debug), 1 (Error), 2 (State change), 3 (Informational), 4 Verbose	1
tls.ca_file	CA 证书文件的绝对路径
tls.crt_file	crt 证书文件的绝对路径.
tls.key_file	私钥文件的绝对路径
tls.key_passwd	可选的私钥文件密码

Command Line

$ bin/fluent-bit -i cpu -o tcp://127.0.0.1:5170 -p format=json_lines -v

我们使用 CPU 输入插件收集 CPU 使用的数据指标，并以 JSON 格式将它们发送到以 netcat 监听的服务端点中，如:

Start the TCP listener

在终端中运行以下命令，netcat 将开始在 TCP/5170 端口上监听消息:

$ nc -l 5170

启动 Fluent Bit:

$ bin/fluent-bit -i cpu -o stdout -p format=msgpack -v
