Use different combinations of log_level and log_level_replica to configure what gets logged on each of the nodes.

my_app.py  --log_level warning --log_level_replica error

Add the log_on_each_node 0 parameter for multi-node environments.
```bash
my_app.py  --log_level warning --log_level_replica error --log_on_each_node 0
set to only report errors
my_app.py  --log_level error --log_level_replica error --log_on_each_node 0
