HTTP GELF input and HTTP Keep-Alive

Graylog Central (peer support)
1

Hello,

I installed a graylog server and I use a GELF HTTP input behind an HAProxy instance.
I noticed that a lot of message are dropped as soon as I use the HTTP-Keep-Alive.
As soon I disable that, 100% of my messages are ingested.

  • OS Information:
    Debian 11

  • Package Version:
    graylog-server 5.1.3-1

I tried to sent my messages directly to the graylog server, same result.

Thanks for your help.

Are you seeing any errors in your graylog server log? (typically /var/log/graylog-server/server.log)

edit: i did some quick testing, but unfortunately wasn’t able to replicate any issues using the GELF HTTP input and the ‘TCP keepalive’ checkbox.

I have the same issue. graylog community, custom python client. If I enable keepalive in requests (using the session object) only the first message works. Using individual connections in the client works.

no errors in log

5.0.9
