fix(dashboards): Use equation prefix for ttid/ttfd contribution rate in Mobile Vitals#109525
Conversation
…in Mobile Vitals The Span Operations table in the Mobile Vitals dashboard uses `ttid_contribution_rate()` and `ttfd_contribution_rate()` as aggregates. These functions are not recognized by Explore's yAxis filter, so they were silently dropped when clicking "Open in Explore". Prefix them with `equation|` so they route through the equations path, which passes the yAxis filter and allows Explore to resolve them via EAP.

The Span Operations table in the Mobile Vitals dashboard uses
ttid_contribution_rate()andttfd_contribution_rate()as aggregates. When clicking "Open in Explore", these were silently dropped becausegetWidgetExploreUrlfilters aggregates to only those present ineventView.getYAxisOptions()— which only recognizes functions known natively to Explore.Prefixing with
equation|fixes this: equations pass theisAggregateEquation()check ingetYAxisOptions(), so they're included in the yAxis options and flow through to Explore correctly. The functions are defined in EAP (src/sentry/search/eap/spans/formulas.py), so Explore can resolve them.The backend companion PR (#109521) adds these functions to the arithmetic allowed list so they pass equation validation.
Follows the same pattern as #108045 (Frontend Overview dashboard).
Note: This PR depends on #109521 landing first.
