CentralLog helps recording the logs by MyOperator standards

centrallog

CentralLog helps recording the logs by MyOperator standards.

The format of the log message is

{
    "time":<unix-epoch>,
    "mc_time":<unix-epoch in microseconds>,
    "ip":"<host-ip-address>",
    "service": <application/service name>,
    "class":"<source class name logging this>",
    "data":{
        "uid":"<unique log identifier>",
        "msg":"<actual message>",
        "acl":<acl numeric representation>
    },
    "title": <logging context provider>
}

For description please refer to Documentation.

Features

• Auto-format log message to desired form by simply configuring the logger.

Installation

To install the centrallog package run the following commands:

$ git clone https://github.com/myoperator/centrallog-py.git
$ pip install -e centrallog-py

Quickstart

For the impatient:

from myoperator.centrallog import centrallog
FORMAT = '%(name)s: (%(asctime)s) [%(levelname)s] - %(message)s'
centrallog.basicConfig(format=FORMAT)
logger = centrallog.getLogger('testlogger')
logger.error("Log message")

Configurations

The basic configuration of logger is same as the python’s builtin logging library.

For customizing message-format use the following class methods.

basicConfig(**kwargs)

This method is same as the logging’s basicConfig(**kwargs).

configure(servicename, hostname=’’, uid=’’)

This method is used to configure the servicename, the hostname, the uuid of the logger throughout the program.

TIP: Use this method once throughout the program before logging any message.

is_configured()

Check if a logger is configured and return true if it is configured, else false.

get_configuration()

Returns the configuration tuple(servicename, hostname, uid).

Logging Methods

centrallog supports all the log methods of the logging library with an additional optional keyword-argument acl which shows the relevancy of the log.

The value of acl(Access Control List) can only be one of the following:

1 - developer (default)
2 - support
4 - customer

Example: To log an error message relevant to the customer(acl = 4).

logger.error('message', acl=4)

centrallog also provide some additional methods with default acl behaviour.

dlog(level, message, *args, **kwargs)

developer specific log(acl=1).

slog(level, message, *args, **kwargs)

support specific log(acl=2).

clog(level, message, *args, **kwargs)

customer specific log(acl=4).

Loggin with title

To add a title to the log message centrallog provide one of the two ways.

Using title keyword argument in every log message.

And using title(text) method.

Example:

logger.title('title here').dlog('message here')
logger.warning('message...', title='Title here')

Tip: On using both method and keyword, keyword will get higher precedence.
