You can provide your own logging configuration to Agno, to be used instead of the default ones. This can be useful if you need your system to log in any specific format.

​
Specifying a custom logging configuration

You can configure Agno to use your own logging configuration by using the configure_agno_logging function. 
import logging

from agno.agent import Agent
from agno.utils.log import configure_agno_logging, log_info

# Set up a custom logger
custom_logger = logging.getLogger("custom_logger")
handler = logging.StreamHandler()
formatter = logging.Formatter("[CUSTOM_LOGGER] %(levelname)s: %(message)s")
handler.setFormatter(formatter)
custom_logger.addHandler(handler)
custom_logger.setLevel(logging.INFO)
custom_logger.propagate = False

# Configure Agno to use the custom logger
configure_agno_logging(custom_default_logger=custom_logger)

# All logging will now use the custom logger
log_info("This is using our custom logger!")

agent = Agent()
agent.print_response("What is 2+2?")

​
Logging to a File

You can configure Agno to log to a file instead of the console: 
import logging
from pathlib import Path

from agno.agent import Agent
from agno.utils.log import configure_agno_logging, log_info

# Create a custom logger that writes to a file
custom_logger = logging.getLogger("file_logger")

# Ensure tmp directory exists
log_file_path = Path("tmp/log.txt")
log_file_path.parent.mkdir(parents=True, exist_ok=True)

# Use FileHandler to write to file
handler = logging.FileHandler(log_file_path)
formatter = logging.Formatter("%(levelname)s: %(message)s")
handler.setFormatter(formatter)
custom_logger.addHandler(handler)
custom_logger.setLevel(logging.INFO)
custom_logger.propagate = False

# Configure Agno to use the file logger
configure_agno_logging(custom_default_logger=custom_logger)

# All logs will be written to tmp/log.txt
log_info("This is using our file logger!")

agent = Agent()
agent.print_response("Tell me a fun fact")

​
Multiple Loggers

You can configure different loggers for your Agents, Teams and Workflows: 
import logging

from agno.agent import Agent
from agno.team import Team
from agno.workflow import Workflow
from agno.workflow.step import Step
from agno.utils.log import configure_agno_logging, log_info

# Create custom loggers for different components
custom_agent_logger = logging.getLogger("agent_logger")
custom_team_logger = logging.getLogger("team_logger")
custom_workflow_logger = logging.getLogger("workflow_logger")

# Configure handlers and formatters for each
for logger in [custom_agent_logger, custom_team_logger, custom_workflow_logger]:
    handler = logging.StreamHandler()
    handler.setFormatter(logging.Formatter("[%(name)s] %(levelname)s: %(message)s"))
    logger.addHandler(handler)
    logger.setLevel(logging.INFO)
    logger.propagate = False

# Workflow logs at DEBUG level when debug_mode is enabled
# Set workflow logger to DEBUG to see these logs
custom_workflow_logger.setLevel(logging.DEBUG)

# Apply the configuration
configure_agno_logging(
    custom_default_logger=custom_agent_logger,
    custom_agent_logger=custom_agent_logger,
    custom_team_logger=custom_team_logger,
    custom_workflow_logger=custom_workflow_logger,
)

# All logging will now use the custom agent logger by default
log_info("Using custom loggers!")

# Create agent and team
agent = Agent()
team = Team(members=[agent])

# Agent will use custom_agent_logger
agent.print_response("What is 2+2?")

# Team will use custom_team_logger
team.print_response("Tell me a short joke")

# Workflow will use custom_workflow_logger
workflow = Workflow(
    debug_mode=True,
    steps=[Step(name="step1", agent=agent)]
)
workflow.print_response("Tell me a fun fact")

​
Using Named Loggers

As it’s conventional in Python, you can also provide custom loggers just by setting loggers with specific names. This is useful if you want to set them up using configuration files. Agno automatically recognizes and uses these logger names:
  • agno will be used for all Agent logs
  • agno-team will be used for all Team logs
  • agno-workflow will be used for all Workflow logs
import logging
from agno.agent import Agent
from agno.team import Team
from agno.workflow import Workflow
from agno.workflow.step import Step

# Set up named loggers BEFORE creating agents/teams/workflows
logger_configs = [
    ("agno", "agent.log"),
    ("agno-team", "team.log"),
    ("agno-workflow", "workflow.log"),
]

for logger_name, log_file in logger_configs:
    logger = logging.getLogger(logger_name)
    logger.setLevel(logging.INFO)
    handler = logging.FileHandler(log_file)
    handler.setFormatter(logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s"))
    logger.addHandler(handler)
    logger.propagate = False

# Agno will automatically detect and use these loggers
agent = Agent()
agent.print_response("Hello from agent!")  # Agent logs will go to agent.log

team = Team(members=[agent])
team.print_response("Hello from team!")  # Team logs will go to team.log

# Workflow requires debug mode to use the workflow logger
workflow = Workflow(
    debug_mode=True,
    steps=[Step(name="step1", agent=agent)]
)
workflow.run("Hello from workflow!")  # Workflow logs will go to workflow.log
