Debugging

2 levels of debugging supported.

  • debug (prints info logs)
  • detailed debug (prints debug logs)

The proxy also supports json logs. See here

debug​

via cli

$ litellm --debug

via env

os.environ["LITELLM_LOG"] = "INFO"

detailed debug​

via cli

$ litellm --detailed_debug

via env

os.environ["LITELLM_LOG"] = "DEBUG"

JSON LOGS​

Set JSON_LOGS="True" in your env:

export JSON_LOGS="True"

OR

Set json_logs: true in your yaml: 

litellm_settings:
    json_logs: true

Start proxy 

$ litellm

The proxy will now all logs in json format.

Control Log Output​

Turn off fastapi's default 'INFO' logs

  1. Turn on 'json logs' 
litellm_settings:
    json_logs: true
  1. Set LITELLM_LOG to 'ERROR'

Only get logs if an error occurs. 

LITELLM_LOG="ERROR"
  1. Start proxy 
$ litellm

Expected Output: 

# no info statements

Common Errors​

  1. "No available deployments..."
No deployments available for selected model, Try again in 60 seconds. Passed model=claude-3-5-sonnet. pre-call-checks=False, allowed_model_region=n/a.

This can be caused due to all your models hitting rate limit errors, causing the cooldown to kick in.

How to control this?

  • Adjust the cooldown time
router_settings:
    cooldown_time: 0 # 👈 KEY CHANGE
  • Disable Cooldowns [NOT RECOMMENDED]
router_settings:
    disable_cooldowns: True

This is not recommended, as it will lead to requests being routed to deployments over their tpm/rpm limit.
