Re: Load Balancing - 2 Active nodes & 1 Inactive until threshold

Not sure if this is what you're looking for, but you can use the 'max' parameter per member to set the limit of connections and on the last member use the 'status=+H' parameter to put it into a hot standby mode.

Dear Community

I currently have a setup similar to the one below for load balancing.

ProxyPass / balancer://something/ stickysession=JSESSIONID

<Proxy balancer://something>

  BalancerMember ajp://xxx.xxx.xxx.xxx:11009 route=node1

  BalancerMember ajp://xxx.xxx.xxx.xxx:12009 route=node2

  BalancerMember ajp://xxx.xxx.xxx.xxx:13009 route=node3

</Proxy>

With this setup, traffic is divided equally between the three nodes.  However, I would like traffic to be handled only by the first two nodes and node3 only comes into play when a threshold has been reached.  For example lets say I reached a 100 connections then node 3 gets activated and the traffic is spread across the three nodes.

I had a look at the loadfactor option and my understanding is that all nodes are active all the time within the cluster, unless I have miss something or misunderstood the option.

How will I go about setting up the configuration I have in mind, if it is possible?

Thank you in advance.

Kind Regards

Leon
