Splunk add on AWS connection pool is full

KwonTaeHoon — Mon, 19 Feb 2024 14:20:22 GMT

Hello

I'm collecting cloudtrail logs by installing Splunk add on AWS in the Splunk heavy forwarder.

The following logs are occurring in the aws:cloudtrail:log source type in the _internal index.

" ~ level=WARNING pid=3386853 tid=Thread-7090 logger=urllib3.connectionpool pos=connectionpool.py:_put_conn:308 | Connection pool is full, discarding connection: bucket.vpce-abc1234.s3.ap-northeast-2.vpce.amazonaws.com. Connection pool size: 10"

Should Splunk add on AWS increase the Connection pool size?

How can I increase the Connection pool size?

Curiously, I would like to know the solution for this log.

Thank you.

I know it has been a while, but did you ever find a solution? I have just encountered this same problem.
