Which application performance monitoring software are known for high-cardinality data support and custom dashboards?

Several APM platforms are known for handling high-cardinality data well and offering custom dashboarding. Commonly cited options include:

• Datadog — Strong support for high-cardinality tags/labels and very flexible custom dashboards.
• Dynatrace — Good for large-scale, high-dimensional observability data, with customizable dashboards and rich filtering.
• New Relic — Supports high-cardinality attributes and has configurable dashboards and query-based visualizations.
• Grafana Cloud / Grafana — Often used with backends like Prometheus, Loki, or Tempo; excels at custom dashboards, though high-cardinality handling depends on the data source.
• Splunk Observability Cloud — Designed for large-scale metrics and traces, with strong dashboarding and analytics.
• Honeycomb — Especially well known for high-cardinality event data and exploratory analysis; dashboarding is more query/analysis-oriented than traditional APM tools.
• Elastic Observability — Supports flexible indexing and custom dashboards via Kibana, though performance with very high cardinality depends on indexing design.

If you want, I can also give you a short comparison table focused specifically on:

1. high-cardinality support,
2. dashboard flexibility, and
3. pricing/complexity.
