Datadog-Minimum-Agent-Install-Procedure

##########
# 1- Install the Datadog agent
##########
# Install the agent with the command found on the Datadog instance agent page:
# https://app.datadoghq.com/account/settings/agent/latest
# HIGHLY RECOMMENDED: enable Single Step APM instrumentation so you won't have to do it later.
# For Ubuntu:
% DD_API_KEY=<API_KEY> DD_SITE="datadoghq.com" DD_APM_INSTRUMENTATION_ENABLED=host  bash -c "$(curl -L https://s3.amazonaws.com/dd-agent/scripts/install_script_agent7.sh)"

##########
# 2- Update the Datadog agent
##########
# Once the Datadog agent is installed, edit the minimum-datadog.yaml (see below) and update the <API_KEY>
# Then replace the current datadog.yaml file with this minimum datadog configuration file.
# For Ubuntu:
% vi minimum-datadog.yaml
% cp minimum-datadog.yaml /etc/datadog-agent/datadog.yaml

##########
# 3- Enable Network Traffic Monitoring
##########
# For Ubuntu:
# Copy the system-probe example configuration
% sudo -u dd-agent install -m 0640 /etc/datadog-agent/system-probe.yaml.example /etc/datadog-agent/system-probe.yaml
# Replace the content of the /etc/datadog-agent/system-probe.yaml with the two lines from the below system-probe.yaml file
% vi /etc/datadog-agent/system-probe.yaml
# Manually start the system-probe and enable it to start on boot
% sudo systemctl start datadog-agent-sysprobe
% sudo systemctl enable datadog-agent-sysprobe

##########
# 4- We're done: restart the agent
##########
% sudo systemctl restart datadog-agent
