Infrastructure Integration

Configuration

1. Ensure that stats are enabled on your HAProxy configuration

Add the following to your haproxy.conf and restart haproxy:

listen stats :9000  # Listen on localhost:9000
mode http
stats enable  # Enable stats page
stats hide-version  # Hide HAProxy version
stats realm Haproxy\ Statistics  # Title text for popup window
stats uri /haproxy_stats  # Stats URI
stats auth <your_username>:<your_password>  # Authentication credentials

1. Configure the agent by editing /etc/nutanix/epoch-dd-agent/conf.d/haproxy.yamlin the collectors.

Example:

init_config:

instances:
    - url: https://localhost:9000/haproxy_stats
      username: <your_username>
      password: <your_password>

1. Check and make sure that all yaml files are valid with following command:

   /etc/init.d/epoch-collectors configcheck
   

2. Restart the Agent using the following command:

   /etc/init.d/epoch-collectors restart
   

3. Execute the info command to verify that the integration check has passed:

   /etc/init.d/epoch-collectors info
   

The output of the info command should contain a section similar to the following:
