Custom metricbeat sql query not ingest into Elasticsearch?

Hi
Can anyone kindly help me with a custom metricbeat sql query not ingest into Elasticsearch?

Do refer to the attached debug log I have gotten from the server metricbeat log.

The log did not show any error, however, I can't find the data in my Kibana. So, I've guessed that Elasticsearch did not ingest or has drop the event. If there is such event, should there be any log I can find in Elasticsearch?

Your help is greatly appreciated!

Regards
Willy
