How to emit console.log output when using javascript-lang for custom scripts?

Elastic Stack Elasticsearch
1

Hi all -- I'd like to emit to stdout information within my custom .js
script (located in /elasticsearch/1.4.2/config/scripts/test.js).

I've tried both console.log and print (just a guess), but neither work:

"error": "ElasticsearchIllegalArgumentException[failed to execute script];
nested: EcmaError[ReferenceError: "console" is not defined.
(Script2.js#19)]; "
"error": "ElasticsearchIllegalArgumentException[failed to execute script];
nested: EcmaError[ReferenceError: "print" is not defined.
(Script1.js#19)]; "

Any way for me to hook into stdout to emit logging information this way?
Thanks very much.

Tim

Hello Tim ,

Its very much possible from groovy , by accessing the Elasticsearch logger
instance.
You should be able to do something similar for javascript too.
Some good folks from Elasticsearch has given a good documentation on it
against my issue.

import org.elasticsearch.common.logging.; *

*ESLogger logger=ESLoggerFactory.getLogger('myscript'); *

*logger.info http://logger.info('This is a log message'); *

LINK - Expose logger object in the scripts · Issue #9068 · elastic/elasticsearch · GitHub

Thanks
