seqpylogger 1.1.1

python loghandler for seq

SeqPyLogger

SeqPyLogger is a python loghandler for seq.

Usage

import os

os.environ["SEQ_APIKEY"] = "xSxExQxAxPxIxKxExYx"
os.environ["SEQ_SERVER"] = "http://localhost:8794/"
os.environ["Environment"] = "Staging"

import logging
from seqpylogger import SeqPyLogger

root = logging.getLogger()
root.setLevel(logging.INFO)
seqLogger = SeqPyLogger(buffer_capacity=10)
root.addHandler(seqLogger)

logger = logging.getLogger("MyLogger")

logger.debug("Debug log message")
logger.info("Informational log message")
logger.warning("Warning log message")
logger.error("Error log message")
logger.critical("Critical log message")
logger.fatal("Critical log message")

logger.info("Test log message with argument %s", "dummy argument")
logger.info("Test log message with arguments %s, %s", "dummy argument 1", "dummy argument 2")

try:
    raise Exception("Some issue")
except:
    logging.exception("An error occured but now we have the stacktrace")
    # logging.error("There was an error", exc_info=1)  # alternative to .exception()

# logs are flushed every 10 seconds and every 10 logs

An alternative way of setting the handler is using the dictConfig

import os
import time
import logging
import logging.config

os.environ["SEQ_APIKEY"] = "xSxExQxAxPxIxKxExYx"
os.environ["SEQ_SERVER"] = "http://localhost:8794/"
os.environ["Environment"] = "Staging"

logger_config = {
    "version": 1,
    "disable_existing_loggers": True,
    "root": {
        "level": logging.INFO,
        "handlers": ["seq"]
    },
    "handlers": {
        "seq": {
            "level": logging.INFO,
            "class": "seqpylogger.SeqPyLogger"
        },
    },
}

logging.config.dictConfig(logger_config)

logging.info("Example message")

except:
    logging.fatal("This time no stacktrace")
