Sensor Lifecycle Management
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 satellite-url
(under Satellite Settings) to the desired host:port
value.
...
# --------------------------------------------------------------------------------------------
# Satellite Settings:
# --------------------------------------------------------------------------------------------
# host:port for the collector service receiving the sensor's API traces.
# mention the scheme http/https if you decide not to use gRPC for sensor satellite communication
satellite-url: <set to desired host:port value>
# --------------------------------------------------------------------------------------------
...
Configure sensor environment
The eBPF sensor environment is configured in /etc/default/levo-ebpf-sensor
. The default env value is staging
Edit /etc/default/levo-ebpf-sensor
, and set LEVO_ENV
to the desired env value (eg. prod
, qa
)
# Environment Variables for levo-ebpf-sensor.service
MALLOC_CONF="background_thread:true,narenas:1,tcache:false,dirty_decay_ms:0,muzzy_decay_ms:0,abort_conf:true"
LEVO_ENV="staging"
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
Get Sensor Status
sudo systemctl status levo-ebpf-sensor
Stop Sensor
sudo systemctl stop levo-ebpf-sensor
Check Sensor Logs
journalctl -u levo-ebpf-sensor.service -b -f --since "15min ago"
# If journalctl isn't providing logs, you can alternatively:
sudo cat syslog | grep 'levo-ebpf-sensor'
Show Sensor Config
cat /etc/levo/sensor/config.yaml
Uninstall Sensor
sudo apt remove --purge levo-ebpf-sensor
sudo apt clean
