How to Install Telegraf on Mac

Telegraf is a plugin-driven server agent that collects and sends metrics and data from various sources to InfluxDB. It's an open-source tool and is widely used to monitor service metrics, system metrics, and any other metric or data that an application produces.

In this tutorial, we will guide you through the Telegraf installation process on macOS.

Prerequisites

Before proceeding with the installation of Telegraf, you need to make sure that your macOS is up-to-date and has the following dependencies installed:

• GCC compiler (command line tools)
• OpenSSL (or LibreSSL)

You can check the installed version of OpenSSL using the following command:

$ openssl version

If OpenSSL is not installed, you can install it using Homebrew, which is a package manager for macOS.

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew install openssl

Install Telegraf

To install Telegraf on macOS, follow the below steps:

1. Download Telegraf from the official repository:

   $ curl -O https://dl.influxdata.com/telegraf/releases/telegraf-1.21.2_darwin_amd64.tar.gz
   

   Note: Replace the version number in the command with the latest version number.

2. Once the download is complete, extract the contents of the package:

   $ tar xvfz telegraf-1.21.2_darwin_amd64.tar.gz
   

3. Navigate to the extracted folder and copy the telegraf.conf file to the /etc directory:

   $ cd telegraf-1.21.2
   $ sudo cp telegraf.conf /etc/telegraf.conf
   

4. Start the Telegraf service:

   $ sudo launchctl load /Library/LaunchDaemons/org.influxdata.telegraf.plist
   

   The above command starts the Telegraf service and creates a log file at /var/log/telegraf/telegraf.log. You can check the log file to ensure that the service is running correctly.

   $ tail -f /var/log/telegraf/telegraf.log
   

5. To stop the Telegraf service, use the following command:

   $ sudo launchctl unload /Library/LaunchDaemons/org.influxdata.telegraf.plist
