Name

error-log-logger is a plugin which pushes the log data of APISIX's error.log to TCP servers.

This plugin will provide the ability to send the log data which selected by the level to Monitoring tools and other TCP servers.

This plugin provides the ability as a batch to push the log data to your external TCP servers. If not receive the log data, don't worry, it will automatically send the logs after the timer function expires in our Batch Processor.

For more info on Batch-Processor in Apache APISIX please refer. Batch-Processor
