Indexer auto-discovery


Splunk 6.3 introduced a very usable and important feature for distributed environments. This feature simplifies forwarder management, which automatically detects new peer nodes in a cluster, and thus, load balancing is handled by itself.

Example

Let us understand the use of indexer auto-discovery using the following cluster example image. The following image shows forwarders sending data to peer nodes. The peer node list and other relevant messages are being communicated from the cluster master to the forwarders:

The following are the uses/advantages of indexer auto-discovery:

  • There is no need for configuration on forwarders specifying the number of peer nodes in the given cluster. The forwarder is automatically informed with the updated list of peer nodes by the master. Thus, when a peer node fails or new peer nodes are added in a cluster, there is no configuration requirement on forwarders.

  • There is no need to know the number of peer nodes when adding or removing a forwarder...
