How do you build a Splunk dashboard, and when is it better than Grafana? [Advanced]
Answer
A Splunk dashboard is built from SPL searches, panels, inputs, tokens, and visualizations. It is better than Grafana when the primary workflow is log/event investigation, security analytics, audit drill-down, or complex SPL correlation. Grafana is usually better for metric-heavy SLO dashboards.
Technical explanation
Splunk dashboards are excellent for drilling from an aggregate into raw events.
Grafana shines when time-series metrics from Prometheus/Mimir/Thanos are the primary data source.
Many incident workflows use both: Grafana for service symptoms and Splunk for correlated logs.
Hands-on example
Example: create a Splunk dashboard with inputs for service, environment, and trace_id. Panels show error trend, top error codes, recent deploy versions, and raw correlated logs. Link to it from the Grafana SLO dashboard using service and time range variables.
