logger-master

A package for pushing serialized error log which generated by loguru to remote storage.

Description:

A package for pushing serialized error log which generated by loguru to remote storage (including mongodb / redis / fluentd).

How To Use:

With MongoDB

• parameters:
  • mongo_instance(object): mongodb instance
  • mongo_db(str): database for storing log data
  • mongo_collection(str): collection for storing log data
  • terminal_displayed(bool): display log information on terminal screen or not
  • rotation(str): loguru rotation
  • serialize(bool): data serialized or not
  • log_format(str): loguru format
  • log_path(str): file path for storing log data
  • custom_func(function): function for custom serialized data

import json
from pymongo import MongoClient
from logger_master.logger import MongoLogger

# pushing log to mongodb instance

mongo_uri = 'mongodb://root:root@localhost:27017/?authMechanism=SCRAM-SHA-1'
mongo_instance = MongoClient(mongo_uri)

# basic usage for pushing log with specific database and collection
logger = MongoLogger(mongo_instance=mongo_instance,
                     mongo_db='my_log',
                     mongo_collection='my_log_collection')

# pushing serialize log to ./my_log/log_file
logger = MongoLogger(mongo_instance=mongo_instance,
                     mongo_db='my_log',
                     mongo_collection='my_log_collection',
                     serialize=True,
                     log_path='./my_log/log_file',
                     rotation='1 week')

# disable display log on screen
logger = MongoLogger(mongo_instance=mongo_instance,
                     mongo_db='my_log',
                     mongo_collection='my_log_collection',
                     log_path='./my_log/log_file',
                     terminal_displayed=False)

# pushing serialized log with custom format
def custom_function(serialized_data):
    if not isinstance(serialized_data, dict):
        serialized_data = json.loads(serialized_data)
    serialized_data.update({'new_key': 'new_value'})
    return serialized_data


logger = MongoLogger(mongo_instance=mongo_instance,
                     mongo_db='my_log',
                     mongo_collection='my_log_collection', 
                     custom_func=custom_function)

try:
    100 / 0
except Exception as e:
    logger.error(str(e))

With Redis

• parameters:
  • redis_instance(object): redis instance
  • key_prefix(str): prefix for redis key
  • terminal_displayed(bool): display log information on terminal screen or not
  • rotation(str): loguru rotation
  • serialize(bool): data serialized or not
  • log_format(str): loguru format
  • log_path(str): file path for storing log data
  • custom_func(function): function for custom serialized data

import json
import redis
from logger_master.logger import RedisLogger

# basic usage for pushing log to redis instance

redis_instance = redis.StrictRedis(host='localhost',
                                   password='root',
                                   port='root')

# pushing log to mongodb with 'my_error_log' key prefix
logger = RedisLogger(redis_instance=redis_instance,
                     key_prefix='my_error_log')

# pushing serialize log to ./my_log/log_file
logger = RedisLogger(redis_instance=redis_instance,
                     key_prefix='my_error_log',
                     serialize=True,
                     log_path='./my_log/log_file',
                     rotation='1 week')

# disable display log on screen
logger = RedisLogger(redis_instance=redis_instance,
                     key_prefix='my_error_log',
                     log_path='./my_log/log_file',
                     terminal_displayed=False)

# pushing serialized log with custom format
def custom_function(serialized_data):
    if not isinstance(serialized_data, dict):
        serialized_data = json.loads(serialized_data)
    serialized_data.update({'new_key': 'new_value'})
    return serialized_data


logger = RedisLogger(redis_instance=redis_instance,
                     key_prefix='my_error_log',
                     custom_func=custom_function)

try:
    100 / 0
except Exception as e:
    logger.error(str(e))

With Fluentd

• parameters:
  • hostname(str): fluentd hostname
  • port(int): fluentd port
  • key_prefix(str): prefix for fluentd key
  • terminal_displayed(bool): display log information on terminal screen or not
  • rotation(str): loguru rotation
  • serialize(bool): data serialized or not
  • log_format(str): loguru format
  • log_path(str): file path for storing log data
  • custom_func(function): function for custom serialized data

import json
from logger_master import FluentdLogger

# pushing log log to fluentd

# basic usage for pushing log data to fluentd
logger = FluentdLogger(hostname='localhost',
                       port=24224,
                       key_prefix='mongo')

# pushing serialize log to ./my_log/log_file
logger = FluentdLogger(hostname='localhost',
                       port=24224,
                       key_prefix='mongo',
                       serialize=True,
                       log_path='./my_log/log_file',
                       rotation='1 week')

# disable display log on screen
logger = FluentdLogger(hostname='localhost',
                       port=24224,
                       key_prefix='mongo',
                       log_path='./my_log/log_file',
                       terminal_displayed=False)


# pushing serialized log with custom format
def custom_function(serialized_data):
    if not isinstance(serialized_data, dict):
        serialized_data = json.loads(serialized_data)
    serialized_data.update({'new_key': 'new_value'})
    return serialized_data


logger = FluentdLogger(hostname='localhost',
                       port=24224,
                       key_prefix='mongo',
                       custom_func=custom_function)

try:
    1 / 0
except Exception as e:
    logger.error(msg=str(e))

you can also push log to both fluentd and mongodb with fluent-plugin-mongo.
