数据采集 采集源配置 envoy 指标采集

envoy 指标采集

简介

采集 envoy 数据指标上报到 DataFlux 中。

前置条件

配置

envoy 配置

进入 DataKit 安装目录下的 conf.d/envoy 目录，复制 envoy.conf.sample 并命名为 envoy.conf。示例如下：

admin:
  access_log_path: "/dev/null"
  address:
    socket_address: { address: 127.0.0.1, port_value: 9901 }

运行 envoy 程序并指定配置文件，例如：

sudo envoy -c envoy_config.yaml

datakit 配置

打开 DataKit 采集源配置文件夹（默认路径为 DataKit 安装目录的 conf.d 文件夹），打开envoy/envoy.conf文件修改配置。

示例配置及说明如下：

[[inputs.prom]]
    # envoy 指标来源 http(https)://HOST:PORT/stats/prometheus
    # 通常只需要修改 host 和 port 即可
    # 必填
    url = "http://127.0.0.1:9901/stats/prometheus"

    # 采集间隔时长，数字+单位，有效的时间单位 "ns", "us" (or "µs"), "ms", "s", "m", "h"
    # 不可以小于等于 0
    # 必填
    interval = "10s"
    
    # 是否开启 HTTPS TLS，如果开启则需要同时配置下面的3个路径
    tls_open = false
    # tls_ca = "/tmp/ca.crt"
    # tls_cert = "/tmp/peer.crt"
    # tls_key = "/tmp/peer.key"
    
    # 自定义 tags
    # 建议配置以区分数据来源
    # [inputs.prom.tags]
    # from = "127.0.0.1:9901"
    # tags1 = "value1"

说明：

  • 如果 envoy 接口需要使用 HTTPS 访问，需要在配置文件中将tls_open设置为true，且配置3个证书和私钥文件路径
  • 使用命令例如curl 127.0.0.1:9901/stats/prometheus 根据返回内容判断是否需要使用 HTTPS
  • 使用命令例如curl --cacert ca.crt --cert peer.crt --key peer.key -L https://127.0.0.1:9901/stats/prometheus 验证 tls 证书和私钥是否可用
  • 证书和私钥码只支持 PEM 编码
