• UDP;

Get AsyncGELF

pip install asyncgelf

Usage

GELF TCP

import asyncio
import asyncgelf

async def main(message):
    handler = asyncgelf.GelfTcp(
        host='127.0.0.1',
    )

    await handler.tcp_handler(message)

asyncio.run(main(message))

GELF TCP with custom timestamp

import asyncio
import asyncgelf

from datetime import datetime


async def main(message):
    handler = asyncgelf.GelfTcp(
        host='127.0.0.1',
    )
    event_time = "2024-02-06 08:25:56.789"
    timeformat = "%Y-%m-%d %H:%M:%S.%f"
    await handler.tcp_handler(message, datetime.strptime(event_time, timeformat).timestamp())

asyncio.run(main(message))

GELF HTTP

import asyncio
import asyncgelf

async def main(message):
    handler = asyncgelf.GelfHttp(
        host='127.0.0.1',
    )

    await handler.http_handler(message)

asyncio.run(main(message))

GELF UDP

import asyncio
import asyncgelf

async def main(message):
    handler = asyncgelf.GelfUdp(
        host='127.0.0.1',
    )

    await handler.udp_handler(message)

asyncio.run(main(message))

Additional field

Expect Dict with the following moments:

• All keys must start with underscore (_) prefix;
• _id can't be an additional field;
• Allowed characters in field names are any word character (letter, number, underscore), dashes and dots

import asyncio
import asyncgelf

async def main(message):
    additional_field = {
      '_key_1': 'value_1',
      '_key_2': 'value_2',
    }
    
    handler = asyncgelf.GelfTcp(
        host='127.0.0.1',
        additional_field=additional_field
    )

    await handler.tcp_handler(message)

asyncio.run(main(message))

Available params

• host Required | Graylog server address;
• port Optional | Graylog input port (default: 12201);
• gelf_version Optional | GELF spec version (default: 1.1)
• level Optional | The level equals to the standard syslog levels (default: 1);
• scheme Optional | HTTP Scheme for GELF HTTP input only (default: http);
• tls Optional | Path to custom (self-signed) certificate in pem format (default: None)
• compress Optional | Compress message before sending it to the server or not (default: False)
• compress_level Optional | Set compression level: available from 1 (BEST_SPEED) to 9 (BEST_COMPRESSION) (default: 1)
• debug Optional | Additional information in error log (default: False)
• additional_field Optional | Dictionary with additional fields which will be added to every gelf message (default: None)
• dns_resolve Optional | Variable host will be checked to existing DNS as parameter and if dns is found, then on initialization will resolve to ip and variable will be updated. By default, UDP handler gets resolved by DNS on every log message. See more: #91305 (default: False)
