Prerequisites

This skill calls SigNoz MCP server tools heavily (signoz_list_metrics, signoz_get_field_keys, signoz_execute_builder_query, signoz_get_top_metrics, signoz_check_metric_usage, signoz_check_metric_cardinality, signoz_aggregate_logs, signoz_aggregate_traces, signoz_search_logs, signoz_list_alert_rules, signoz_get_alert, signoz_get_service_top_operations). Before running the workflow, confirm the signoz_* tools are available. If they are not, the SigNoz MCP server is not installed or configured — run signoz-mcp-setup first. The whole investigation is grounded in these queries; without the server there is nothing to analyze.

Read both reference files before drawing conclusions:

references/otel-attribute-cardinality.md — classify any metric label you encounter.
references/infra-do-not-drop.md — the metrics that power the built-in Infrastructure page and the APM/Services page (span-derived signoz_* RED metrics); never present these as "safe to drop" even when usage shows them unused.
