Logstash Gelf Output TCP connected only on times

[phoppe93]

Dear Logstash Team.

i have an issue on Kubernetes with logstash and graylog.

The logstash only connected via tcp one times to graylog.

Here a snipped how i connect to different graylogs inside a cluster

output {
if ([rand_int]) {
if( [rand_int] == 0 ) {
gelf {
id => "output.gelf.0"
codec => "plain"
protocol => "TCP"
host => "graylog.logging.svc.cluster.local"
port => 12201
sender => "%{source_host}"
ignore_metadata => ["@timestamp", "@Version", "severity", "host", "source_host", "short_message"]
}
} else if( [rand_int] == 1 ) {
gelf {
id => "output.gelf.1"
codec => "plain"
protocol => "TCP"
host => "graylog.logging.svc.cluster.local"
port => 12201
sender => "%{source_host}"
ignore_metadata => ["@timestamp", "@Version", "severity", "host", "source_host", "short_message"]
}

Second Issue:

The graylog container are scalable on cpu usage.

After the scale up and one more graylog container is available the logstash not try to connect to the new container.

I have to restart the logstash container.

Is it possible to to have the option to reconnect at an interval and look for new graylog containers ?

Thanks

Could you not just put a load balancer in front of your graylog containers?
