Otherwise, I suggest you restart the containers and then display the logs from the last few minutes.
# Restarting the 3 containers
docker restart gladys gladys-z2m-mqtt gladys-z2m-zigbee2mqtt
# Displaying logs from the 3 containers
docker logs -f --since 1m gladys
docker logs -f --since 1m gladys-z2m-mqtt
docker logs -f --since 1m gladys-z2m-zigbee2mqtt
You can adjust the --since 1m (number of minutes) according to the time you want, of course 
There will be far fewer logs displayed!
