Monitor HAProxy

Use the HAProxy for InfluxDB v2 template to monitor your HAProxy instances. First, apply the template, and then view incoming data. This template uses the HAProxy input plugin to collect metrics stored in an HAProxy instance and display these metrics in a dashboard.

The HAProxy for InfluxDB v2 template includes the following:

• one dashboard: HAProxy
• one bucket: haproxy
• label: haproxy
• one Telegraf configuration: HAProxy input plugin, InfluxDB v2 output plugin
• one variable: bucket

Apply the template

1. Use the influx CLI to run the following command:

   influx apply -f https://raw.githubusercontent.com/influxdata/community-templates/master/haproxy/haproxy.yml
   

   For more information, see influx apply.

   Note: Ensure your influx CLI is configured with your account credentials and that configuration is active. For more information, see influx config.

2. Install Telegraf on a server with network access to both the HAProxy instances and InfluxDB v2 API.

3. In your Telegraf configuration file (telegraf.conf), do the following:

   • Set the following environment variables:
     • INFLUX_TOKEN: Token must have permissions to read Telegraf configurations and write data to the haproxy bucket. See how to view tokens.
     • INFLUX_ORG: Name of your organization. See how to view your organization.
     • INFLUX_HOST: Your InfluxDB host URL, for example, localhost, a remote instance, or InfluxDB Cloud.

4. Start Telegraf.
