Indexer performance

Splunk Employee

We are about to add additional indexers to our Splunk infrastructure. We believe this will help with some of our search performance issues and indexing throughput issues. We also have seen that our current indexers will have high CPU (min of 8 core) and memory (min of 64GB).

Does anyone out there have some good searches or dashboards for measuring performance of the indexers? Anything to indicate whether the new indexers are making a difference for us? We do use SoS for looking at the index pipeline and some other metrics.

Thanks.

Have a faster disk rather than Memory and big CPU. 64 GB memory is mostly unnecessary. If required have 16 Core CPU. Until and unless your disk is capable of handling the indexing and give output to your searches faster you won't see the performance increase..

Thanks. Disk is fast. In an case I am looking for ways to measure and monitor the performance.

Add the indexer as search peer, Run search which you feel as slow. It should also have the data which is required. See inspect and check the run duration. This is quite abstract way to check if it has any performance improvement.

You can use Splunkit, comes with both an indexing benchmark as well as a search benchmark. https://apps.splunk.com/app/749/
