/ Splunk Cost Evaluation
Measure which logsSplunk needs
Run Expanso close to selected log sources, then compare downstream volume, operational coverage, and Splunk cost against your baseline.
/ The problem
Where Splunk costs accumulate
License and infrastructure effects depend on the Splunk agreement, source mix, and operational requirements.
High-volume sources
Measure Input
Identify sources and event classes that drive daily ingestion.
Operational coverage
Protect Signal
Document the events required by alerts, investigations, retention, and audit workflows.
Routing complexity
Review Paths
Map how selected event classes reach indexes and downstream consumers.
/ The Expanso difference
Evaluate filtering close to the log source
Define a representative policy, target connected nodes with labels, and compare outputs before changing production routing.
/ How it works
What to test
Use customer-owned baselines and acceptance criteria.
Log filtering
Selected Events
Test customer-defined rules and inspect every retained and rejected event class.
Aggregation
Selected Summaries
Compare summaries with the raw events required by operational and security teams.
Priority routing
Selected Destinations
Verify critical-event routing, then exercise destination failure, backpressure, restart, buffering, and recovery before broader deployment.
/ Outcomes
Customer-specific evaluation
Expanso does not promise a universal reduction. Results depend on source mix, policy, Splunk configuration, and pricing.
Record source volume, event classes, and current Splunk cost.
Measure retained volume and validate alerts, searches, and investigations.
Use observed results to decide whether and where to expand.
/ Why Expanso
Why evaluate Expanso for Splunk
Near-source execution
Run data-processing pipelines on connected nodes close to where logs are generated.
Declarative jobs
Define jobs with YAML and target evaluation nodes with labels.
Measured rollout
Validate a representative flow before changing a wider production path.
/ FAQ
Frequently asked questions
How much will we save?
There is no universal result. Establish an ingestion and cost baseline and calculate the observed effect using your own Splunk agreement.
Will filtering affect security visibility?
That must be tested. Define protected event classes, compare alerts and searches, and obtain approval from the teams responsible for detection and retention.
Can we start with one source?
Yes. A bounded evaluation should use a representative source, explicit acceptance criteria, and a reversible routing plan.
What happens if Splunk is unreachable mid-evaluation?
Test it deliberately. Exercise destination failure, backpressure, restart, buffering, and recovery on the selected pipeline components, and measure node resources, latency, and destination behavior while you do. An evaluation is complete only once the teams responsible for detection and retention approve the observed downstream behavior.
