Getting data in

Hi,

I have a scenario where the heavy forwarder queue gets filled and data doesn't appear quickly in Splunk when the indexers are running on a full capacity (i.e. indexers overwhelmed with data from forwarders).
Is there a way to separate queues for HF and the forwarders, so that they have a separate queue for the incoming data ?

Thanks in advance.

Thanks,
Pravin

Hi @_pravin 

The only way you could separate different queues for different forwarders would be to create multiple inputs on different ports and have certain forwarders send to certain ports, but the reality is this isnt going to give you much of an improvement or speed up ingestion.

I would focus on why the indexers are overloaded, this could be by assessing any heavy parsing regex in transforms.conf, increasing the number of indexers in your cluster (Horizontal scaling), adding resources to your indexers (Vertical scaling), reviewing any long-running searches on your Splunk stack or potentially increasing the number of parallelIngestionPipelines (default of 1) to 2 if your servers have the adequate resource available (see https://help.splunk.com/en/splunk-enterprise/get-started/deployment-capacity-manual/9.3/performance-... and https://help.splunk.com/en/splunk-enterprise/administer/manage-indexers-and-indexer-clusters/9.1/man... for more information).

If the HFs are waiting for the indexers then the problem is on the indexers.  Fix the indexers and the HFs should be fine again.

It's not clear what you mean by "separate queues for HF and the forwarders" since HFs *are* forwarders.
