Setup Instructions

General instructions on using InfluxDB Templates can be found in the use a template document.

The data for the dashboard is populated by the included Telegraf configuration which includes the sFlow Input. You may need to customize the input configuration, specific the service_address value, depending on where your sFlow packets are coming from. More information can be found in the Telegraf sFlow Input documentation.

The Telegraf Configuration requires the following environment variables:

  • INFLUX_TOKEN - The token with the permissions to read Telegraf configs and write data to the telegraf bucket. You can just use your master token to get started.
  • INFLUX_ORG - The name of your Organization (this will be your email address on the InfluxDB Cloud free tier)
  • INFLUX_HOST - The URL of your InfluxDB host (this can your localhost, a remote instance, or InfluxDB Cloud)

You MUST set these environment variables before running Telegraf using something similar to the following commands

  • This can be found on the Load Data > Tokens page in your browser: export INFLUX_TOKEN=TOKEN
  • Your Organization name can be found on the Settings page in your browser: export INFLUX_ORG=my_org

Running Telegraf

To gather sFlow data from your network, download and install Telegraf. InfluxData provides native packages for a number of distributions as well as binaries that can be executed directly.

Start Telegraf using the instructions from the Load Data > Telegraf > Setup Instructions link in the UI.

Customizations

You can customize it based on your sFlow setup. More information can be found in the Telegraf sFlow Input documentation.
