Installed on Linux Host​

Configure Satellite Address (host:port information)​

The Satellite address is configured in /etc/levo/sensor/config.yaml. The default host:port for Satellite is localhost:4317.

Edit /etc/levo/sensor/config.yaml, and set collector-endpoint (under Satellite Settings) to the desired host:port value.

...
# --------------------------------------------------------------------------------------------
# Satellite Settings:
# --------------------------------------------------------------------------------------------
# host:port for the collector service receiving the sensor's API traces.
collector-endpoint: <set to desired host:port value>
# --------------------------------------------------------------------------------------------
...

A Sensor restart is required for this to take effect.

Start Sensor​

# Note: The default config file is located at: '/etc/levo/sensor/config.yaml'
sudo systemctl start levo-ebpf-sensor

sudo systemctl status levo-ebpf-sensor

Stop Sensor​

sudo systemctl stop levo-ebpf-sensor

Check Sensor Logs​
