Elasticsearch:Overview of plug-ins

Last Updated:Sep 18, 2024

Alibaba Cloud Logstash supports more than 100 system plug-ins, including open source plug-ins and self-developed plug-ins. The plug-ins improve cluster capabilities such as data transmission, data processing, and log debugging. This topic describes the system plug-ins that are supported by Alibaba Cloud Logstash.

Alibaba Cloud Logstash supports only system plug-ins. The system plug-ins are built-in plug-ins. You can install or remove them based on your business requirements. For more information, see Install or remove a Logstash plug-in. The Alibaba Cloud Logstash clusters on which the plug-ins run belong to customers. We recommend that you do not use the clusters to perform illegal operations.

The following tables describe the system plug-ins that are supported by Alibaba Cloud Logstash.
