For engineers Collectors

Hai guys, i’m try to setup collector in ec2 instance which i got error when run the stream collector. I’m using kinesis which already setup it. Here my config.hocon file:

  http.server {
    # To obtain the hostname in the collector, the 'remote-address' header
    # should be set. By default, this is disabled, and enabling it
    # adds the 'Remote-Address' header to every request automatically.
    remote-address-header = on

    raw-request-uri-header = on

    # Define the maximum request length (the default is 2048)
    parsing {
      max-uri-length = 32768
      uri-parsing-mode = relaxed
    }
  }
}

and here the errors that i get when i run it.

You’ve only got INFO statements at the moment being returned. The REST interface being bound to an IP address is what should be happening if the collector has started properly.

Hai mike,
if the ip address already bound that means tracker can talk to the collector rite? correct me if i’m wrong.

what i’m understand is, when bound is successful, then tracker can talk to that bound ip address.

Yes - if the collector has successfully bound to an address then the collector is running correctly. You can confirm this by CURLing the collector URL and returning a 200

curl -I 127.0.0.1/i

HTTP/1.1 200 OK

its work perfectly mike. Thank you.
