 For example to see ThingsBoard node logs execute the following command:
 
 `
-$ docker-compose logs -f tb-core1 tb-rule-engine1
+$ docker-compose logs -f tb-core1 tb-core2 tb-rule-engine1 tb-rule-engine2 tb-mqtt-transport1 tb-mqtt-transport2
 `
 
 Or use `docker-compose ps` to see the state of all the containers.
