Stop paying Splunk to index noise your team will neverquery.
Splunk pricing is tied to daily ingest volume. Debug events in production, repeated health checks, and schema-invalid entries all consume your license. Cerbi filters them before the Universal Forwarder ever sees them.
The problem
Splunk license costs grow with application verbosity, not just application value
Every log event your application emits - whether it is a meaningful business event or a repeated health-check ping - counts against your Splunk daily ingest limit. Teams commonly find that 40 - 70% of their Splunk volume is debug output, infrastructure noise, or duplicate events that no analyst queries. Cribl can filter in the pipeline, but you are already transmitting those bytes from your application.
Before and after
// Governance runs at emission time, inside the application process. The sink receives only governed output.
Architecture
Filter before the Universal Forwarder, not after
CerbiStream intercepts events inside your application process before they reach the Universal Forwarder or HTTP Event Collector. Dropped events never enter the Splunk pipeline and do not count toward your license.
Your application

Logger framework
MEL / Serilog / NLog
CerbiStream

Splunk UF / HEC

Splunk index
indexes governed events only
// Cerbi runs inside your process. No sidecar, no agent, no additional network hop.
Why existing tools are too late
Cribl and pipeline tools reduce forwarding, not emission
Events are already transmitted before Cribl sees them
Cribl processes events after they have left your application and entered the collection pipeline. Network bandwidth and upstream buffer costs are already incurred for every event Cribl later drops.
Heavy forwarder filtering adds operational overhead
Splunk Heavy Forwarder transforms and filters events in the pipeline layer. This requires infrastructure, configuration management, and a separate team to maintain - and it still does not prevent events from being emitted and transmitted from your application.
Application-level filtering requires developer involvement anyway
Debug log suppression in production is ultimately a developer and platform team decision. Cerbi enforces that decision at the logger level where developers already work.
How Cerbi fits with your stack
Cerbi works with all Splunk forwarder and ingestion methods
Compatible with Universal Forwarder
Files written by your application after Cerbi governance are forwarded by UF as normal. UF configuration does not change.
Compatible with HTTP Event Collector
Serilog Splunk sink and NLog Splunk target receive governed output from CerbiStream. HEC receives fewer, cleaner events.
Works alongside Cribl
Cerbi reduces what enters the Cribl pipeline. Cribl can then focus on routing and enrichment rather than volume reduction.
Level-based filtering by environment
Suppress verbose and debug events in production while allowing them in development and staging, without changing application code.
