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.

Read on to install the integration, and to see what data we collect.

Compatibility and requirements

Before installation, ensure you meet these requirements:

A New Relic account. Don't have one? Sign up for free! No credit card required.
HAProxy versions 1.3 - 2.x.
HAProxy statistics page is enabled and accessible.

Quick start

If you're not running HAProxy in Kubernetes or ECS environments, we recommend our guided install. Our guided install uses our infrastructure agent and our CLI to set up the HAProxy integration, and discovers other applications and log sources running in your environment and then recommends which ones you should instrument.

The guided install works with most setups. But if it doesn't suit your needs, there are other install options below.

Ready to get started? Click the relevant button, depending on which data center region you use. When you're done with the install, return to this documentation to review the configuration options.

Guided install, US region

Guided install, EU region

Install and activate

If you're not using the guided install, follow the instructions for your environment:

Install the infrastructure agent, and replace the INTEGRATION_FILE_NAME variable with nri-haproxy.
Change directory to the integrations folder:
```
cd /etc/newrelic-infra/integrations.d
```

Copy the sample configuration file:

sudo cp haproxy-config.yml.sample haproxy-config.yml

Edit the haproxy-config.yml file as described in the configuration settings.

Install the infrastructure agent, and replace the INTEGRATION_FILE_NAME variable with nri-haproxy.
Download the nri-haproxy .MSI installer image from:
https://download.newrelic.com/infrastructure_agent/windows/integrations/nri-haproxy/nri-haproxy-amd64.msi
To install from the Windows command prompt, run:
```
msiexec.exe /qn /i PATH\TO\nri-haproxy-amd64.msi
```
In the Integrations directory, C:\Program Files\New Relic\newrelic-infra\integrations.d\, create a copy of the sample configuration file by running:
```
cp haproxy-config.yml.sample haproxy-config.yml
```
Edit the haproxy-config.yml configuration file using the configuration settings.

Update your integration

This integration doesn't automatically update. For best results, regularly update the integration package and the infrastructure agent.

Post-installation tasks

When you're done with the install, you can set configuration options. Some configurations are required to get the integration to work, while some are optional.

Configure the integration

If you enabled this integration via our ECS or Kubernetes integration, see those docs:

An integration's YAML format configuration is where you can place required login credentials and configure how data is collected. The options you change depend on your setup and preference.

The configuration file has common settings applicable to all integrations like interval, timeout, inventory_source. To read all about these common settings refer to our Configuration Format document.

If you're still using our legacy configuration/definition files, see the on-host integrations standard configuration format for help.

Specific settings related to HAProxy are defined using the env section of the configuration file. These settings control the connection to your HAProxy instance as well as other security settings and features.

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

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
