Our HG command line tool is an interactive way to install an agent on your system, without ever needing to touch a configuration file! This tool currently supports Telegraf installation, with more agents to be added in the future (like OpenTelemetry).

Once you've installed HG-CLI, you can run it as a TUI (Terminal User Interface) or in CLI (Command Line Interface) mode. See our list of commands below for all available installation options and command examples.

Installation

You can find all current releases on GitHub.

Quick Install

Run this command in your terminal (Linux/MacOS).

curl -s "https://www.hostedgraphite.com/scripts/hg-cli/installer/" | sudo sh

This will install the latest released version's binaries into your /usr/local/bin directory.

Homebrew

You can use Homebrew to tap and install the HG-CLI packages for MacOS/Linux. This method supports AMD64/ARM64 architectures and the official GitHub tap can be found HERE.

Add tap:

brew tap hostedgraphite/hgcli

Install:

brew install hg-cli

[Optional] Add to system PATH:

$env:BACKUPPATH = [Environment]::GetEnvironmentVariable("Path", "Machine")
$env:NEWPATH = [Environment]::GetEnvironmentVariable("Path", "Machine")
$env:NEWPATH += ";C:\Program Files\hg-cli"
[Environment]::SetEnvironmentVariable("Path", $env:NEWPATH, "Machine")
Update-SessionEnvironment

Golang

Install using go install

Manual (Binaries)

To manually install, download a preferred version releases page (that matches your OS & ARCH), extract and move the binary file into a desired install location.

Example:

curl -L https://github.com/hostedgraphite/hg-cli/releases/download/<version>/hg-cli_<version>_<os>_<arch>.tar.gz
tar -xf hg-cli_<version>_<os>_<arch>.tar.gz
mv hg-cli /install/path (eg. /usr/local/bin)

Perform Checksum

Optional Step

Download the checksum.txt file from the releases listed assets.

Linux

sha256sum --ignore-missing --check checksums.txt

MacOS

shasum -a 256 --ignore-missing --check checksums.txt

HG-CLI Commands

Once HG-CLI is installed, you can run it as a TUI application, or in CLI mode (for automated installs). Below are all available options and command examples for using this tool.

Run the interactive TUI application (recommended):

hg-cli tui

Run it in CLI mode with the default configuration:

hg-cli agent install telegraf --api-key <HG-API-KEY>

CLI mode for a custom install - to specify which plugins you want:

hg-cli agent install telegraf --api-key <HG-API-KEY> --plugins cpu,disk,mem

CLI mode to update an API key in an existing config (telegraf):

hg-cli agent update-apikey telegraf --api-key <HG-API-KEY> --config <config path>

To uninstall an agent (telegraf):

hg-cli agent uninstall telegraf

Available flags for CLI mode:

• --api-key (required)

• --plugins (plugins to be added during installation)

• --config (config path for updating apikey - required)

• --list (list available monitoring agents)

hg-cli TUI Demonstration

Metrics and Visualizations

Once you have run the HG-CLI and installed an agent, the terminal output will show you that the installation was successful, which plugins were enabled, where your configuration file is located, and the command needed to start the service (required for collecting and forwarding metrics to your HG account).

TUI Installation Output

Once the agent service has been started, you'll be able to locate your system metrics in our Metrics Search UI (with the telegraf prefix). Once telegraf.* metrics have been sent to your account, a Telegraf dashboard will be automatically created and can be located in your HG account (Dashboards ⇒ Telegraf). This auto-dash offers a great starting point and can be customized further!
