How logs, metrics and distributed traces answer different operational questions, what Anypoint Monitoring offers for each (with its tier and deployment limits), and how synthetic testing and real-user monitoring complement each other.

- Certification: Salesforce MuleSoft Integration Foundations
- Exam section: Explain the common technical complexities and patterns in integration development
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-integration-foundations

**Official exam objective:**

> Describe and compare observability approaches for integration solutions including logs, metrics, and tracing.

## What the exam expects

- Choose metrics for trends, dashboards and threshold alerts across all traffic.
- Choose logs to investigate a specific event, error message or failure at a given time.
- Choose distributed tracing to follow one request across several services and see where time is spent.
- Compare synthetic testing with real-user monitoring and explain why teams combine them.
- Describe what Anypoint Monitoring provides and the limits on where traces are available.

Key terms:
- **Metric**: a numeric measurement such as uptime, response time, error rate or request volume, aggregated over time.
- **Log**: a detailed record of an event, such as a request path, response code and execution time.
- **Trace**: the path of one request through a service pipeline, made of spans from the root span down.
- **Synthetic testing**: simulated requests sent at regular intervals to measure availability and response times.
- **Real-user monitoring (RUM)**: capturing actual user interactions to see how real users experience the API.

## Key facts

| Fact | Detail | Source |
|---|---|---|
| Monitoring goal | Dashboards and alerts reduce MTTI | [Anypoint Monitoring](https://docs.mulesoft.com/monitoring/) |
| Metric scope | Application-level for Mule apps and APIs, not VPC traffic | [Anypoint Monitoring](https://docs.mulesoft.com/monitoring/) |
| Traces by cloud | US and EU control planes only | [Anypoint Monitoring](https://docs.mulesoft.com/monitoring/) |
| Mule app trace sampling | 10% | [Examining Traces](https://docs.mulesoft.com/monitoring/traces) |
| Trace hosts | CloudHub 2.0 and Runtime Fabric (Limited Availability) | [Examining Traces](https://docs.mulesoft.com/monitoring/traces) |
| Trace lookback | 15 minutes by default, up to seven days | [Examining Traces](https://docs.mulesoft.com/monitoring/traces) |
| Log Points | Real-time logs, no redeployment; Advanced or Titanium | [Log Points](https://docs.mulesoft.com/monitoring/log-points) |
| Synthetic plus RUM | Combine them for a comprehensive view | [API Monitoring Guide](https://www.mulesoft.com/api/api-monitoring-guide) |

## Check yourself

- When can a team without the Usage-based or Titanium tier still search logs?
- What does the root span of a trace represent?
- Which log levels can a Log Point generate for a connector?
