   Sentry's Trace Explorer and Issues page let developers filter/aggregate by arbitrary properties like impacted users, browser, or device with 'flexible queries and filters' without needing pre-defined dashboards or indexes (sentry-docs-9, sentry-docs-10, sentry-docs-36). This implies ad-hoc high-cardinality filtering (e.g. user id) is supported, but the evidence never explicitly addresses request-id-level grouping, cardinality limits, or performance at scale.

   Docs claim traces/logs can be searched and filtered by any span attribute or log field, including arbitrary high-cardinality values like user_id/request_id, without requiring pre-defined indexes (signoz-docs-3, signoz-docs-7). However, community hands-on reports on SigNoz's ClickHouse schema find that accessing map attributes (the mechanism used for flexible, high-cardinality fields) is 10-50x slower than regular columns, indicating real performance limitations for exactly this use case (signoz-comm-6, signoz-comm-7).

   Sentry's core product docs directly describe issue grouping with filtering, stack traces/suspect commits, release/source map tracking via Sentry CLI, and regression detection surfaced through the Issues page and alerting on new issues. Community evidence (HN) corroborates real-world use of core error monitoring at scale, though it focuses more on self-hosting operational concerns than the grouping/regression UX specifically. missing for 10: independent hands-on account specifically validating regression detection and issue-grouping accuracy (most community commentary is about self-hosting ops, not this exact workflow).

   The evidence pack shows SigNoz’s trace, log, metric, and dashboard capabilities but contains no mention of an error-issue grouping feature, stack-trace capture, release tracking, or regression detection — capabilities typical of dedicated error-tracking tools like Sentry. Since APM platforms commonly offer this kind of error tracking, the axis is applicable, but no evidence supports it here.
