Minimalistic Elasticsearch logging handler

elasticsearch-logging-handler

This is a minimalistic Elasticsearch logging handler for python. This handler uses only url as an authentication method. For more robust authentication consider CMRESHandler.

Package on PyPI - https://pypi.org/project/elasticsearch-logging-handler/

Parameters for ElasticHandler:

Name	Type	Required	Default	Description	Example
host	str	True	-	Url for Elasticsearch cluster. Currently, this handler support only basic authentication through providing user and password in the url.	https://user:[e-mail]:9200, https://my-cluster.es:9200
index	str	True	-	Name of the Index to write in.	preprocessing-logs
level	int	False	0 (NOTSET)	Minimal logging level for the handler. Handler will only process messages with level larger than this parameter.	20, logging.WARNING
batch_size	int	False	1000	Size of the buffer that stores logs before sending to Elasticsearch. If buffer is full, send batch immediately, without waiting for the flush_period	2000 - send batches of maximum size 2000
flush_period	float	False	1.0	Period during which handler will accumulate logs into batch before sending it ot the cluster.	10.0 - wait 10 seconds before sending
timezone	str	False	None	Timezone for which to transform @timestamp for the record.	'Europe/Amsterdam', 'Australia/Sydney'

ElasticHandler is nonblocking, meaning any logging call e.g. logging.exception will not block calling thread. which is useful in the case of high logging load.
