HAProxy monitoring integration

Our HAProxy integration collects and sends inventory and metrics from your HAProxy instance to the New Relic platform, where you can aggregate and visualize key performance metrics for the HAProxy server, frontends, and backends.

To get the most out of this page, select the installation method that fits your environment. You need a New Relic account before starting the installation process.

팁

Use guided install to quickly see your data in the UI

The guided install is a single CLI command you can run to monitor your instance. It's a good option for small organizations, or for anyone who wants to test out New Relic.

For a more permanent and scalable solution, we recommend the standard manual install of the agent: keep reading for how to do that.

Example configurations

Here are some example YAML configurations:

This is the basic configuration for collecting Metrics and Inventory from your localhost:

integrations:
  - name: nri-haproxy
    env:
      STATS_URL: http://haproxy-instance/stats
      USERNAME: haproxy_user
      PASSWORD: haproxy_password
      HA_PROXY_CLUSTER_NAME: haproxycluster
    interval: 15s
    labels:
      env: production
      role: load_balancer
    inventory_source: config/haproxy

This configuration uses the environment variable HAPROXY_STATS to populate the STATS_URL setting of the integration:

integrations:
  - name: nri-haproxy
    env:
      METRICS: "true"
      STATS_URL: {{HAPROXY_STATUS}}
      USERNAME: haproxy_user
      PASSWORD: haproxy_password
      HA_PROXY_CLUSTER_NAME: haproxycluster
    interval: 15s
    labels:
      env: production
      role: load_balancer

This configuration monitors multiple HAProxy servers from the same integration. The first instance (STATUS_URL: https://1st_haproxy-instance/stats) collects metrics and inventory, the second instance (STATUS_URL: https://2nd_haproxy-instance/stats) only collects metrics.

integrations:
  - name: nri-haproxy
    env:
      METRICS: "true"
      STATS_URL: http://1st_haproxy-instance/stats
      USERNAME: haproxy_user
      PASSWORD: haproxy_password
      HA_PROXY_CLUSTER_NAME: haproxycluster1
    interval: 15s
    labels:
      env: production
      role: load_balancer

  - name: nri-haproxy
    env:
      INVENTORY: "true"
      STATS_URL: http://1st_haproxy-instance/stats
      USERNAME: haproxy_user
      PASSWORD: haproxy_password
      HA_PROXY_CLUSTER_NAME: haproxycluster1
    interval: 60s
    labels:
      env: production
      role: load_balancer
    inventory_source: config/haproxy

  - name: nri-haproxy
    env:
      METRICS: "true"
      STATS_URL: http://2nd_haproxy-instance/stats
      USERNAME: haproxy_user
      PASSWORD: haproxy_password
      HA_PROXY_CLUSTER_NAME: haproxycluster2
    interval: 15s
    labels:
      env: production
      role: load_balancer

HAProxy configuration options

The Apache integration collects both metrics and inventory information. This table shows what each configuration option applies to.

Setting	Description	Default	Applies To
`STATS_URL`	A URL pointing to the HAProxy stats page.	N/A	M/I
`USERNAME`	Username for the HAProxy connection.	N/A	M/I
`PASSWORD`	Password for the given user.	N/A	M/I
`HA_PROXY_CLUSTER_NAME`	A user-defined name to uniquely identify the cluster being monitored. Required.	N/A	M/I
`METRICS`	Set to `true` to enable Metrics-only collection.	`false`
`INVENTORY`	Set to `true` to enable Inventory-only collection.	`false`

The values for these settings can be defined in several ways:

Adding the value directly in the config file (the most common way).
Replacing the values from environment variables using the {{}} notation. This requires infrastructure agent version 1.14.0 or higher. For more information, see Infrastructure configuration or see the environment variable example.
Using secrets management. Use this to protect sensitive information, such as passwords that would be exposed in plain text in the configuration file. For more information, see Secrets management.

Labels

You can further decorate your metrics using labels. Labels allow you to add attributes (key/value pairs) to your metrics, which you can then use to query, filter, or group your metrics.

Our default sample config file includes examples of labels but, because they're not mandatory, you can remove, modify, or add new ones of your choice.

labels:
  env: production
  role: load_balancer
