Getting Data In

Heavy Forwarder and Loadbalancing

Hello,

Here at my company we have one search head and three indexers.... We have a standalone server that has an Heavy Forwarder installed, we have a script on the server that is polling a database and sending the data to the forwarder through a TCP stream which gets indexed and forwarded to the indexers. The problem we are having is that the heavy forwarder is not properly distributing the data across the indexers and instead is sending everything to only one indexer... what should we do to solve this problem?

I believe that the problem is that it is a TCP stream. The autolb can't make the stream break. We see the same issue with routers sending data to a forwarder which load balances between 3 indexers. You will most likely notice that if you restart the splunk instance on the one indexer that is getting all the tcp stream data that it will change to the next one.

How did you set up load balancing ? Does load balancing work for other sourcetypes forwarded by the heavy forwarder ?
