Hey @abntkpi

On your Graylog Sidecar dashboard does the collector Status show running? I would imagine that if GL sidecar is not working then the field (i.e., gl2_source_collector) would not be present.

thank you for reply.
i remove graylog 5 and install graylog 4 .
I use * on graylog 4 , gray log show me error Query parsing error: Cannot parse query, cause: ‘*’ or ‘?’ not allowed as first character in WildcardQuery.
This is very strange. I did everything according to the graylog document, but even though I changed the versions, I still have a problem.

Hey @abntkpi

Check Graylog Sidecar log to find more information on whts goign on, It could be a connection issue or a incorrect configuration.
