- Log in to your Datadog account and navigate to the Agent Installation page.
- Choose “Linux” as your platform and select the latest version of the Datadog agent.
- Copy the installation command for your desired version of the agent.
- Connect to your Red Hat Linux system and open a terminal window.
- Run the installation command to download and install the Datadog agent.
Here is an example command to install the latest version of the Datadog agent on a Red Hat Linux system:
DD_AGENT_MAJOR_VERSION=7 DD_API_KEY=<your_api_key> DD_SITE="datadoghq.com" bash -c "$(curl -L https://s3.amazonaws.com/dd-agent/scripts/install_script.sh)"
In this command, replace <your_api_key> with your Datadog API key.
Once the installation is complete, you should see a message indicating that the Datadog agent is running. You can verify that the agent is running by running the following command:
sudo systemctl status datadog-agent
This should show the status of the Datadog agent service, including whether it is active and running.
You can then configure the Datadog agent to collect metrics and logs from your system by editing the agent configuration file at /etc/datadog-agent/datadog.yaml. For example, you can enable system metrics collection by uncommenting the following lines in the configuration file:
# Uncomment this to collect system metrics:
# - system
Save your changes to the configuration file and restart the Datadog agent service using the following command:
sudo systemctl restart datadog-agent
The agent should now be collecting metrics and logs from your system and sending them to your Datadog account for monitoring and analysis.
