We have a Server A where Graylog is installed with a Stream X
And Another Server B where Graylog is installed with a Stream Y
Server A has Internet connectivity via an http_proxy (http://proxyserver:80).
There are environment variables defined at the Shell level on A
We wrote a sample nodejs script which pushes a test message to http://ServerB:12201 and executed it on Server A. We can see the data on the Server B.
This confirms that the GELF endpoint is reachable via the Proxy Server and the ports are open.
Now, we have configured GELF OUTPUT for Stream X and push data to Server B at http://ServerB:12201
We then configured the below parameter in Server.conf and restarted Graylog
http_proxy_uri = http://proxyserver:80
But now, we see errors in the logs like
“unable to connect to ServerB”
Below is the configuration for the output:
Gelf ID: 5a473a67644uj814953f4d19 Type: org.graylog2.outputs.GelfOutput connect_timeout: 1000 hostname: ServerB max_inflight_sends: 512 port: 12201 protocol: TCP queue_size: 512 reconnect_delay: 500 tcp_keep_alive: false tcp_no_delay: false tls_trust_cert_chain: <empty> tls_verification_enabled: false
Please suggest what should we try to solve this.
