I’m very new to HA Proxy and i love it. But now i ran into a problem i could not find an answer for yet.
I’m testing a three node Graylog installation where HA Proxy is doing the balancing of https requests and Syslog messages. The connections of the Syslog servers are long living sessions and therefore i set it to “balance leastconn”. That’s fine so far. But if i have f.ex. to shutdown one of the servers for maintenance and bring it back online later, it of course doesn’t get any connections as long there is no interruption of a connections to the other nodes or a Syslog client restarts f.ex.
Long story short: Is there i way i can force it to re-balance the connections to all nodes out of the box? F.ex. reset some connections to the other nodes if there is a heavy imbalance so that they are re-established and connect to the node which just came back online to keep the number of connections balanced over all nodes.
Could be that it’s already doing something like that. I have only two Syslog clients for testing at the moment.
