To clarify, we’re running a single Splunk instance where the Deployment Server, Indexer, and Search head all reside on the same server so it’s a non-distributed architecture. When I mentioned “deployment,” I was referring both to our overall Splunk setup and the fact that our Deployment Server shares the same host as the Indexer. We have only one indexer, no clustering, and no heavy forwarders (HFs) in use. However, we do have universal forwarders (UFs) installed on various servers, and they’re configured to send data directly to the indexer. Regarding Ingest Actions (IA), I’ve configured one rule locally on the indexer to drop data from the source type PerfmonMK:CPU. The rule uses a regex filter (^PerfmonMk:CPU$) with a drop action. IA rules are applied only on the indexer.
