Configuration Constants and Environment Variables - hacktlib/py-async-http-logging GitHub Wiki

As already explained in our documentation, Async HTTP Logging works based on the Python LogStash library.

To set custom constant values, please override the Python LogStash ones:

from http_logging import AsyncHttpHandler
from logstash_async import constants

constants.QUEUED_EVENTS_FLUSH_INTERVAL = 5.0

Make sure to override the constants after you import the http_logging Classes (e.g. AsyncHttpHandler), as demonstrated above. Otherwise, http_logging defaults might override the values you set.

For a reference of all constant values available, please refer to Options for the asynchronous processing and formatting ⧉ in the Python LogStash documentation.

Optionally, Async HTTP Logging allows you to configure some of these parameters as environment variables.

Here is a complete list:

• ASYNC_LOG_HTTP_PORT: defaults to 80 (converted to int)
• ASYNC_LOG_HTTPS_PORT: defaults to 443 (converted to int)
• ASYNC_LOG_DATABASE_PATH: defaults to 'logging-cache.db'
• ASYNC_LOG_TIMEOUT: defaults to 5.0 (converted to float)
• ASYNC_LOG_ENCODING: defaults to sys.getfilesystemencoding() ⧉
• ASYNC_LOG_QUEUE_CHECK_INTERVAL: defaults to 1.0 (converted to float)
• QUEUED_EVENTS_FLUSH_INTERVAL: defaults to 5.0 (converted to float)
• ASYNC_LOG_QUEUED_EVENTS_FLUSH_COUNT: defaults to 10 (converted to int)
• ASYNC_LOG_QUEUED_EVENTS_BATCH_SIZE: defaults to 10 (converted to int)
• ASYNC_LOG_DATABASE_TIMEOUT: defaults to 2.5 (converted to float)
