Custom Log Levels
Define your own log levels beyond the built-in 11.
Register a Custom Level
python
from logly import logger
logger.level("AUDIT", no=25, color="<magenta>")
logger.level("METRIC", no=15, color="<cyan>")
logger.log("AUDIT", "User action recorded")
logger.log("METRIC", "Request latency: 42ms")
logger.complete()Override Existing Colors
python
from logly import logger
logger.level("DEBUG", color="<blue><bold>")
logger.level("WARNING", color="<red><bold>")
logger.debug("Blue and bold")
logger.warning("Red and bold")
logger.complete()Use Custom Levels with Filters
python
from logly import logger
logger.level("SECURITY", no=45, color="<red><bold>")
sink_id = logger.add(
"security.log",
level="SECURITY", # only SECURITY and above
rotation="daily",
)
logger.log("SECURITY", "Unauthorized access attempt")
logger.complete()
logger.remove(sink_id)INFO
Level priority (no) determines filtering: lower values are more verbose. Set custom levels between existing ones (e.g., 15 between DEBUG=10 and INFO=20).
