Is it possible to combine the two functionalities of Indexing and Heavy Forwarding on a single VM host?

New Member

Guys, I currently have Splunk Enterprise 6.5.0 Free running on a W2k8 R2 host and Universal Forwarders (Windows host) and direct syslog (unix host) feeding log data into it fine.

i am working here on the assumption that Splunk licensing comes into play at the indexer and that any paring down of unwanted events at the Heavy Forwarder will reduce the licensing liabilities? is this assumption correct?

I want to evaluate the Heavy Forwarder parsing functionality for data volume licensing reasons and am wondering if I can combine the two functionalities of the Heavy Forwarding and Indexing on a single VM host? I don't think I can but am trying to limit the number of VMs I have to run for this test scenario. Please refer to the high tech test scenario diagram below 🙂

External Host |                             | Splunk Enterprise Server     |
Log Data      |    >>>>>>>>>>>>>>>>>>>>>    | Heavy Forwarder >>>> Indexer |

Thanks in anticipation. kevbod

You don't need to run a heavy forwarder at all in your scenario. You can parse out the data that you want to drop on the indexer itself. Any data that arrives at the indexer but that is eliminated (prior to being written to disk) does not count against your daily license.

Look at the section named "Filter event data and send to queues" in the documentation here
Note that it says in the opening paragraph: "Although similar to forwarder-based routing, queue routing can be performed by an indexer, as well as a heavy forwarder." In my experience, it is more efficient to do this with the indexer. I would not run a heavy forwarder in your case.

not sure if I'm misunderstanding, but you can drop unwanted events on the indexer too. That happens during the parsing phase which should happen on your indexer with the current setup.

This might be a good page to review as well - high level overview of the phases and where each phase happens in different types of splunk deployments.
