Use global data links with Splunk APM properties to view more resources for APM properties. APM properties are services, traces, spans, and span tags.
With data links, you can associate APM properties with custom dashboards, log events, or entirely custom resources. Data links transfer the context of the property you’re viewing to the resource.
If you’re viewing a service, a data link can transfer information about any endpoints you filtered for, including any filters for selected endpoints, the selected environment, and any tags you filtered for within the selected time range.
If you’re viewing a trace ID, a data link can transfer information about the corresponding service, the operation that created the trace, any global tags for the trace, and the start/end time of the trace.
If you’re viewing a span ID, a data link can transfer information about the corresponding service, the span’s operation, all span tags for the span’s operation, and the start/end time of the span.
If you’re viewing a span tag, a data link can transfer information about the corresponding service, the span’s operation, the span’s ID, the trace’s ID, every other span tag, and the start/end time of the associated span.
The data link can transfer APM property context to these resources:
- Infrastructure Monitoring dashboard
- Splunk instance
- Custom URL
- Kibana
You have to manually configure data links for APM properties before they’re available. For information about creating data links for APM, see Link logs and other resources to Splunk APM services, traces, and spans.
