Exploring APM traces (OpenTelemetry spans)
PostHog captures distributed traces from OpenTelemetry. Each trace is a tree of spans representing a request’s path through services.
Disambiguation: This skill is for APM / OpenTelemetry traces. Do not confuse with LLM analytics traces (agent/model $ai_* events and LLM observability tools) or logs (posthog:query-logs, posthog:logs-*).
MCP tools
| Tool | Purpose |
|---|---|
posthog:query-apm-spans |
Search and filter spans (analytics-style query; parameters live under query) |
posthog:apm-trace-get |
Fetch all spans for a hex trace_id |
posthog:apm-services-list |
List distinct service names |
posthog:apm-attributes-list |
List span or resource attribute keys |
posthog:apm-attribute-values-list |
List values for a specific attribute key |
For aggregates or joins not covered by these tools, posthog:execute-sql may be appropriate once the span schema is confirmed for the project.
