@danielbb Hello Daniel, Please follow the below steps. 1. Install Splunk on all the required instances. 2. Enable the receiving port `9997` on the indexer. 3. If you are forwarding data from a Universal Forwarder (UF) to a Heavy Forwarder (HF) and then to the indexer, ensure the receiving port is open on both the Heavy Forwarder and the indexer. 4. Ensure the following ports are open: 9997: UF to HF and HF to Indexer 8089: Management port between Indexers and Search Heads 8000: Web port for HF and Search Head (optional for indexers in production environments) 5. Add your indexer to the Search Head: - Navigate to Settings > Distributed Search > Distributed Search Setup - Enable distributed search, then go to Settings > Distributed Search > Search Peers - Add the indexer details here and restart the Splunk instance. 6. If required, open port `8000` for the web interface on the Heavy Forwarder and Search Head. While optional for indexers, this port is typically not opened on production indexers. Note:Before configuring Splunk, perform a telnet test to verify port connectivity: - From UF to HF: `telnet <HF_IP_Address> 9997` - From HF to Indexer: `telnet <Indexer_IP_Address> 9997` - From Indexers to Search Heads: Ensure the management port `8089` is open. I hope this helps, if any reply helps you, you could add your upvote/karma points to that reply, thanks.
