AsyncGELF
Async python logging handlers that send messages in the Graylog Extended Log Format (GELF).
List of ready to run GELF handlers
- TCP (with and without TLS);
- HTTP (with and without TLS);
- 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)
