Configure various options

There are numerous configurations available to customise the bot.

options = {
    # Application name would replace the webhook name set during creating of the webhook
    # It would appear as the name of the bot
    # If unset, the default value would be "Application"
    "application_name": "My Server",

    # Service name would be the name of the service sending the message to your Discord channel
    # This would usually be the name of the application sending the notification
    # If unset, the default value would be "Status Bot"
    "service_name": "Backend API",

    # Service icon URL is the icon image for your application
    # This field accepts a URL to the icon image
    # If unspecified, the icon wouldn't be set
    # If misconfigured, the icon wouldn't load and a blank space would appear before the service name
    "service_icon_url": "your icon url",

    # Usually services would run in staging and production environments
    # This field is to specify the environment from which the application is reponding for easy identification
    # If unset, this block would not appear in the message
    "service_environment": "Production",

    # The default importance level of the message
    # The left bar color of the message would change depending on this
    # Available options are
    # - default: 2040357
    # - error: 14362664
    # - warn: 16497928
    # - info: 2196944
    # - verbose: 6559689
    # - debug: 2196944
    # - success: 2210373
    # If the `error` field is set during the construction of the message, the `level` is automatically set to `error`
    # If nothing is specified, `default` color would be used
    "default_level": "info",
}

Examples

Set Service Name, Icon and Environment for easy identification

You can configure the log message with service name, icon and environment for easy identification. The Host field which is the hostname of the server is automatically added for every message.

from discord_logger import DiscordLogger

webhook_url = "your discord webhook url"
options = {
    "application_name": "My Server",
    "service_name": "Backend API",
    "service_icon_url": "your icon url",
    "service_environment": "Production",
    "default_level": "info",
}

logger = DiscordLogger(webhook_url=webhook_url, **options)
logger.construct(
    title="Health Check",
    description="Issue in Auth API!",
    error="Traceback (most recent call last):\n ValueError: Database connect accepts only string as a parameter!",
)

response = logger.send()

Send messages with different log-levels

The log-level indicates the importance of the message. It changes the color of the discord message in particular. Currently supported levels are,

• error
• warn
• info
• verbose
• debug
• success

The log-level can be set during construction of the message like through the parameter level.

If the parameter isn't provided, it'll be set to the one given in default_level. Any invalid input would be ignored and the log-level would be automatically be set to default.

from discord_logger import DiscordLogger

options = {
    "application_name": "My Server",
    "service_name": "Backend API",
    "service_icon_url": "your icon url",
    "service_environment": "Production",
    "default_level": "info",
}

logger = DiscordLogger(webhook_url=webhook_url, **options)
logger.construct(
    title="Celery Task Manager",
    description="Successfully completed training job for model v1.3.3!",
    level="success",
)

response = logger.send()

• Send complete error traceback

The error field can contain any error message. It will be automatically be formatted in the final message. For example, you can send a complete traceback of an error message to debug faster!

import traceback

from discord_logger import DiscordLogger


def get_traceback(e):
    tb = (
        "Traceback (most recent call last):\n"
        + "".join(traceback.format_list(traceback.extract_tb(e.__traceback__)))
        + type(e).__name__
        + ": "
        + str(e)
    )
    return tb


webhook_url = "your discord webhook url"
options = {
    "application_name": "My Server",
    "service_name": "Backend API",
    "service_icon_url": "your icon url",
    "service_environment": "Production",
    "default_level": "info",
}

err = KeyError("`email` field cannot be None")

logger = DiscordLogger(webhook_url=webhook_url, **options)
logger.construct(
    title="Runtime Exception", description=err.__str__(), error=get_traceback(err),
)

response = logger.send()
