  2. ps -ef | grep graylog-collector

Graylog collector (v0.5.0) gets hang

The Graylog Collector is unmaintained and won’t be developed any further. It’s basically abandonware.

I’d recommend switching to another log shipper, such as Logstash, Filebeat, or NXLOG, possibly in combination with the Graylog Collector Sidecar.

Thanks @jochen. Appreciate your quick response. We are planing to shift to sidecar. But currently production release is near by. Any help to handle above is very helpful to us in current situation.

Thanks and Regards,

It might be a bug in Graylog Collector but there won’t be a bug fix, so I’d recommend switching to another log shipper as soon as possible.

Thanks @jochen.
