Hi

Below is flow of reaching to "manage extractor"
Graylog Web UI -> Inputs -> GELF_TCP-9898 -> Manage Extractor.

It gets stuck on “Loading”. With every refresh of URL it prints below message in console log.

Which version of Graylog are you using?

Please post the contents of the “inputs” collection in the MongoDB database:
https://docs.mongodb.com/manual/reference/program/mongoexport/#export-in-json-format

Graylog Version: Graylog 2.1.2+50e449a

jochen · January 31, 2018, 2:06pm

Please upgrade to Graylog 2.4.3 (the latest stable version at the time of writing) and check if the problem occurs there as well.

If it does, please create a bug report with the information from this discussion topic at https://github.com/Graylog2/graylog2-server/issues

amitshah · January 31, 2018, 2:16pm

Hi,

Migration is planned in near future. Is “inputs.json” of any help to understand issue or in resolving this issue?
Is this bug? or some configuration issue?

Thanks for help.
Amit Shah.

jochen · January 31, 2018, 2:32pm

The “order” fields of the extractors in your “inputs” collection look fine in JSON, so it’s either a different type than just number in BSON (the format MongoDB is using internally) or the MongoDB driver used in that particular version of Graylog has a bug.

You can try exporting that particular input in a content pack, delete it, and re-import it from the content pack.
If that doesn’t work, you should delete that particular input and recreate it from scratch.

For reference:

github.com

Graylog2/graylog2-server/blob/2.1.2/graylog2-server/src/main/java/org/graylog2/inputs/InputServiceImpl.java#L242-L245


Long order = 0L;
if (ex.containsField(Extractor.FIELD_ORDER)) {
    order = (Long) ex.get(Extractor.FIELD_ORDER); // mongodb driver gives us a java.lang.Long
}

Hi Chen,

Great help. It worked with recreation of “inputs”.

Thanks a lot.
I really appreciate your help.

Regards,
Amit.
