Send and verify events with MongoDB operation telemetry
Use MongoDB operation telemetry where your app knows the final result. Collect only the fields you need, then verify a test event before building charts.
- 1
Choose the outcome
Slow-operation analysis
- 2
Define the contract
database_system, operation, collection_name, query_fingerprint, and release
- 3
Log the final result
Name the application operation separately from the database command so dashboards remain stable as query implementations change.
- 4
Check the stored event
Exercise a known fixture, then inspect mongodb_operation_completed for one correctly typed terminal row.
Before you start
Before you start
- The MongoDB Node.js driver and telemetry-sh initialized server-side
- A fixed list of operation names that excludes collection documents and filter values
- A reviewed distinction between application timing and database-profiler diagnostics
Delivery setup
Install and initialize server-side
Import telemetry-sh in server-only code and initialize it once with process.env.TELEMETRY_API_KEY. Keep ingestion credentials out of browser bundles, client-visible environment variables, source control, logs, and exception messages.
npm installation
npm install telemetry-sh- 1Create one reusable server-side client. Set its timeout and retry limit.
- 2Log an event when the operation succeeds, fails, retries, or times out.
- 3Send test events with known results and inspect the stored rows before enabling an alert.
Snippet
Start with one structured event
Add this shape where the workflow completes, fails, or retries. Then build the dashboard from real fields.
MongoDB operation telemetry event
await telemetry.log("mongodb_operation_completed", {
database_system: "mongodb",
operation: "workspace_activity.aggregate",
collection_name: "workspace_activity",
query_fingerprint: "workspace_activity_summary_v3",
status: "success",
duration_ms: Math.round(performance.now() - startedAt),
result_count: results.length,
retry_count: 0,
transaction_status: "not_started",
read_preference: "primaryPreferred",
route_template: "/api/workspaces/:workspaceId/activity",
release: process.env.APP_RELEASE,
});Event schema
database_system, operation, collection_name, query_fingerprint, and release
status, duration_ms, result_count, retry_count, and transaction_status
read_preference, write_concern_category, route_template, and error_type
Check your setup
Checkpoint 1
Name the application operation separately from the database command so dashboards remain stable as query implementations change.
Checkpoint 2
Keep filters, update documents, aggregation pipelines, returned documents, connection strings, and unrestricted driver errors out of events.
Checkpoint 3
Use the MongoDB database profiler selectively for native query diagnostics; its captured data can include sensitive query details and needs its own access and retention review.
Verification
Prove the event arrived
Run this after exercising known success and failure cases. Replace the fallback table name if your final event contract differs from the snippet.
MongoDB operation telemetry verification query
SELECT *
FROM mongodb_operation_completed
ORDER BY timestamp_utc DESC
LIMIT 20;Implementation references
Review the event contract, data-safety guidance, and upstream primary documentation before enabling a new production path.
Where to log
Keep the outcome event small and recoverable
This pattern provides
- Record the outcome as an event you can query with SQL.
- Stable fields for dashboards, alerts, and cross-event correlation.
- Test events for checking success, failure, retries, and timeouts.
This pattern does not provide
- An OTLP exporter, automatic collection pipeline, or replacement for detailed traces and diagnostic logs.
- Exactly-once delivery merely because the payload contains an event ID.
- Permission to collect raw provider payloads, user content, credentials, or regulated data.
