Logs and error checking

Hi! Just a few questions from a newbie… lol…

Firstly, how do I set my logs to show me all the relevant information id need?

Secondly, I’m seeing a lot of these in the logs ( i have not touched ANYTHING affecting it, base logs lol). Are any of these an issue?

full_node full_node_server        : ERROR    Exception , exception Stack: Traceback (most recent call last):
  File "chia\server\server.py", line 361, in start_client
  File "aiohttp\client.py", line 763, in _ws_connect
  File "aiohttp\client.py", line 521, in _request
  File "aiohttp\connector.py", line 535, in connect
  File "aiohttp\connector.py", line 892, in _create_connection
  File "aiohttp\connector.py", line 1032, in _create_direct_connection
  File "aiohttp\connector.py", line 969, in _wrap_create_connection
  File "asyncio\base_events.py", line 949, in create_connection
  File "asyncio\selector_events.py", line 473, in sock_connect

And also:

wallet chia.wallet.wallet_node    : WARNING  No keys present. Create keys with the UI, or with the 'chia keys' program.
full_node chia.full_node.full_node: ERROR    Exception in create outbound connections: 
full_node chia.full_node.full_node: ERROR    Traceback: Traceback (most recent call last):
  File "chia\server\node_discovery.py", line 378, in _connect_to_peers
  File "asyncio\tasks.py", line 595, in sleep

I also wanted to know, how do I check the performance of my harvester to ensure it is not too slow or timing out or anything? From my understanding, if it is not performing optimally then there could be farming issues. I am farming and plotting (near max potential) on one system. (For specs, see:Questions from a newbie)

No ideas? lol just checking
