Build it around important user journeys and service objectives, then connect application and runtime telemetry to alerts and an incident response process. Metrics, logs, and traces provide complementary views; real-user monitoring and synthetic checks help you see whether the application works from the user’s perspective.
Start with the outcomes the application must deliver
Begin by identifying the user journeys and service operations that matter most to customers or the business. For each one, decide what you need to know to judge whether it is working: for example, whether it is available, how long it takes, how much traffic it handles, and whether it is producing faults or errors. These are useful indicators only when they connect to a service need and can prompt a decision.

Set service-level objectives (SLOs) for the most important operations, and name the team responsible for responding when an objective is at risk. There is no universal threshold that fits every application: set objectives and alert conditions from your own service requirements. AWS Well-Architected guidance recommends monitoring key performance indicators (KPIs) and SLOs, but leaves their targets to the service owner.

Collect the signals that explain service health
Metrics, logs, and traces answer different questions. Collect them with consistent service and operation context so responders can move between a trend, a specific event, and the request path involved.
#1 Best Overall
- Used Book in Good Condition
| Signal | What it helps answer | Useful production role |
|---|---|---|
| Metrics | Is a rate, count, or duration changing over time? | Track service health and trends, and alert when a meaningful condition is met. |
| Logs | What discrete event occurred, and what context accompanied it? | Investigate errors and events with relevant application or system details. |
| Traces | Which parts of the request path took time or failed across dependencies? | Follow a request through the application and connected services to locate delays or faults. |
A dashboard of isolated signals can show that something changed without showing why. Correlating metrics, logs, and traces around the same service, operation, or request makes it easier to investigate an incident. AWS Well-Architected describes these three signal types as the primary pillars of observability.
Cover the application and its runtime
Application telemetry alone can miss failures or resource problems in the environment that runs the application. Collect both application-level and system-level signals. AWS Prescriptive Guidance describes operating-system logs and metrics alongside application logs and metrics as a minimum; the exact configuration depends on the compute environment.
Rank #2
- Used Book in Good Condition
- Application: capture relevant metrics, structured logs, and traces for critical operations and their dependencies.
- Runtime: add the appropriate host, container, or platform telemetry for the environment in use.
- Shared context: standardize names and service or operation identifiers so telemetry can be related during diagnosis.
Do not assume one collection setup works unchanged across hosts, containers, serverless workloads, and other environments. Choose instrumentation and collection methods that fit the actual runtime.
Check the experience users actually receive
Service telemetry describes what the application and its infrastructure report. Real-user monitoring (RUM) observes actual user interactions, while synthetic monitoring runs checks against important journeys. These approaches complement metrics, logs, and traces: use them when you need direct visibility into user-facing behavior or journey availability.
Choose checks that represent important user actions rather than treating a single probe as proof that every part of the application works. Use service telemetry to investigate a failed or slow check and to understand whether the problem is isolated or broader.
Build dashboards and alerts around decisions
For critical operations, make it possible to see availability, latency, traffic or call volume, faults, and errors together. AWS CloudWatch Application Signals documentation uses these as example measures. A dashboard should help a responder decide whether users are affected and where to investigate, not merely display every metric the system can collect.
Alert on conditions that warrant action, such as a meaningful risk to an SLO or a user-facing failure. Route each alert to an owner and response process. Review false positives and missed incidents, then adjust the conditions so alerts are useful rather than background noise. AWS Well-Architected monitoring guidance recommends validating alert behavior and practicing response through game days.

Compare tools against the application’s deployment model and the way the team operates. Do not choose solely from a feature list: verify that the tool can collect the signals you need, relate them during diagnosis, and fit the access, data-handling, and response requirements of your service.
Best Value
- Used Book in Good Condition
- Deployment compatibility: check support for your runtime, cloud, containers, serverless or on-premises environment, and account structure.
- Telemetry coverage: verify metrics, logs, traces, and any needed real-user or synthetic monitoring.
- Diagnosis: assess trace search, dependency views, and links among requests, logs, metrics, and deployments.
- Objectives and alerting: check support for SLO workflows and whether alert conditions can be tuned and managed by the team.
- Operational fit: consider access controls, data handling, retention, ownership, and the responders’ existing workflow.
- Cost drivers: examine ingest volume, retention, trace sampling, and feature-specific charges. The AWS sources cited here do not provide a neutral, current price comparison.
AWS documentation presents several examples, not an independent comparison of vendors. CloudWatch Application Signals documents application metrics, traces, health views, and SLO tracking. AWS describes OpenTelemetry as an optional collection approach. Amazon OpenSearch application monitoring presents topology with RED metrics—Rate, Errors, and Duration. Product capabilities and availability can change, so verify current documentation for the environment and features you intend to use.

- Define service objectives and ownership. Identify critical journeys and KPIs, set SLOs for important operations, and assign the team that responds when they are at risk.
- Instrument the request path. Emit metrics, structured logs, and distributed traces. Standardize names and context so signals can be related to the same service or operation.
- Add runtime coverage. Collect host, container, or platform telemetry as appropriate to the compute environment, alongside application signals.
- Add user-facing checks. Use RUM for actual interactions and synthetic transactions to probe important journeys where direct user-experience coverage is needed.
- Build views and alerts. Bring the health measures for critical operations together, set actionable alert conditions, and route them to the responsible responders.
- Exercise and refine the process. Run game days, inspect telemetry after incidents, and update indicators as the application and its business use evolve.
AWS Well-Architected monitoring guidance frames the operational goal clearly: monitor a workload after implementation so issues can be remediated before they affect customers. In practice, that requires more than collecting data: the signals must support a decision, and the team receiving an alert must be able to act.
