OpenTelemetry Export Wire Reference
Companion to OpenTelemetry Export. Full wire surface: every metric, log event, attribute, enum, and presence rule.
The surface is additive. Tolerate unknown attributes, events, and enum values. Renames and removals get explicit notice.
Transport and scope

application/x-protobuf),POST - Endpoints:

Resource attributes
One resource per (team, user, surface, entrypoint, surface version) grouping.
| Attribute | Type | Presence | Values / notes |
|---|---|---|---|
service.name | string | Always | Constant cursor |
service.version | string | Optional | Client version when source is desktop/CLI; usually absent on cloud_agent / bugbot |
cursor.team.id | int | Always | Your team id |
cursor.surface | string | Always | unspecified | desktop | cli | cloud_agent | bugbot | grok_bot |
cursor.entrypoint | string | Always | unspecified | desktop | cli | web | mobile | sdk_ts | sdk_py | api | automation | github_pr |
cursor.user.id | int | Optional | Opaque team-scoped user id when the source has one. Often absent on cloud agent. Do not require presence. |
Families
Family ids match the toggles in Team Settings. All default on for a new destination.
| Family id | Signals | Covers |
|---|---|---|
model_usage | metrics + logs | token.usage, cost.usage; api.request, api.error, api.correction |
tool_calls | metrics | tool.calls |
skills_hooks_plugins | logs | skill.activated, hook.execution_complete, plugin.installed |
cloud_agents | logs | cloud_agent.pull_request, cloud_agent.setup, cloud_agent.artifact, cloud_agent.mcp_auth_error |
grok_bot_agent_actions | logs | grok_bot.mcp_tool_call, grok_bot.shell_command, grok_bot.browser_navigation, grok_bot.computer_use_session |
Metrics
All metrics are monotonic delta sums. Metric datapoints carry no correlation IDs; those appear on logs only.
Consume metrics as sums of deltas per series. A series is the resource, the metric name, and the exact datapoint attribute set. Windows for the same series can overlap across flushes.
cursor.token.usage
Unit {token}. Family model_usage.
| Attribute | Type | Presence | Values / notes |
|---|---|---|---|
cursor.token.type | string | Always | input | output | cache_read | cache_creation |
cursor.model.name | string | Optional | Requested public model after routed-intent collapse (auto: to Auto, thinking: to Thinking, pro: to Pro, premium: to Premium; else pass-through). Absent on bugbot or when the source had no model. |
cursor.api.status | string | Optional | success | errored | aborted |
cursor.api.billable | bool | Optional |
cursor.tool.calls

Identity and joins
- Dedupe logs on
cursor.event.id. - Session reconstruction: group logs by
cursor.conversation.id(composer UUID,bc-..., or Grok Bot conversation id). - Billing reconcile grain:
cursor.usage_event.idacrossapi.request/api.error/api.correction. - Metrics do not carry these ids. Use
api.requestlogs for per-conversation token totals.
See Joining sessions on the setup page for recipes.
Delivery semantics
- Logs are at-least-once. Transient failures recover automatically for about 7 days; dedupe on
event.id. Terminal rejections (persistent 4xx, bad payloads) are not replayed. - Metrics are at-most-once. Failed metric requests are not retried or replayed.
- No ordering guarantee. Corrections can arrive after the requests they amend; order by record timestamp.
- OTLP partial success is honored. Rejected items are not re-sent.
- No backfill from before destination activation. Source retention upstream of export is also about 7 days (separate from the delivery retry window).
