HAProxy 性能指标采集

简介

使用 HAProxy 服务器的 stats socket 或 HTTP 统计页面采集数据上报到 DataFlux 中

前置条件

• 已安装 DataKit（DataKit 安装文档）

HAProxy 配置

stats enable 选项可用于添加不进行身份验证的http访问。要启用 unix socket，首先要读取 stats socket 选项。

配置

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

# Read metrics of HAProxy, via socket or HTTP stats page
[[inputs.haproxy]]
  ## An array of address to gather stats about. Specify an ip on hostname
  ## with optional port. ie localhost, 10.10.3.33:1936, etc.
  ## Make sure you specify the complete path to the stats endpoint
  ## including the protocol, ie http://10.10.3.33:1936/haproxy?stats

  ## If no servers are specified, then default to 127.0.0.1:1936/haproxy?stats
  servers = ["http://myhaproxy.com:1936/haproxy?stats"]

  ## You can also use local socket with standard wildcard globbing.
  ## Server address not starting with 'http' will be treated as a possible
  ## socket, so both examples below are valid.
  # servers = ["socket:/run/haproxy/admin.sock", "/run/haproxy/*.sock"]

  ## By default, some of the fields are renamed from what haproxy calls them.
  ## Setting this option to true results in the plugin keeping the original
  ## field names.
  # keep_field_names = 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                       

配置好后，重启 DataKit 即可生效
