Error when using haproxy and dropwizard metrics

[Samuel Mutel]

Hello,

Perhaps the issue is due to haproxy but I would like to post my issue here also to be sure.

I have a haproxy in front of graphite cluster.

My code in my application is:

final Graphite graphite = new Graphite(new InetSocketAddress(serverName, serverPort));
final GraphiteReporter reporter = GraphiteReporter.forRegistry(METRICS)
        .prefixedWith(name(hostname, user))
        .convertRatesTo(TimeUnit.SECONDS)
        .convertDurationsTo(TimeUnit.MILLISECONDS)
        .filter(MetricFilter.ALL)
        .build(graphite);
reporter.start(1, TimeUnit.MINUTES);

In haproxy I see for 5% of the metrics the error below:

1/-1/0 0 CC 2/2/1/1/0 0/0

C : the TCP session was unexpectedly aborted by the client.

C : the proxy was waiting for the CONNECTION to establish on the server. The server might at most have noticed a connection attempt.

It is working correctly if we are using the graphite cluster without haproxy in front.

Any timeout option possible on the client side ?

Thanks.
