Monitoring & Alerting Due Diligence

Observability Coverage, Alert Quality, and Response Integration

Monitoring maturity is one of the clearest indicators of operational discipline. We assess three dimensions: what’s monitored, how it’s monitored, and what happens when monitors fire. Teams with comprehensive observability, well-tuned alerts, and documented response procedures operate at a fundamentally different level than teams relying on customer complaints to detect issues.

Coverage is the starting point. Are application metrics collected (request rate, error rate, latency)? Are infrastructure metrics tracked? Is there synthetic monitoring from the user’s perspective? Each gap represents a blind spot where problems can grow undetected.

Quality matters more than quantity. A team with 20 well-tuned alerts and runbooks for each outperforms a team with 500 alerts that nobody trusts. We assess alert precision (does it fire when there’s a real problem?), recall (does it catch all real problems?), and actionability (does the team know what to do when it fires?).

Monitoring Gaps That Let Outages Grow Undetected

The highest-risk finding is teams with no monitoring at all - more common than you’d expect, especially in AI-built applications where the focus was features, not operations. These teams detect outages from customer complaints. Recovery time is measured in hours because diagnosis starts from scratch each time.

The second risk tier is teams with monitoring but poor alerting. They have Grafana dashboards but nobody watches them. They have Prometheus metrics but no alerts. The data exists to detect problems quickly, but the feedback loop to engineers isn’t built. This is cheaper to fix than missing monitoring but still represents operational risk.

Monitoring cost trajectory is a financial risk. Teams on Datadog or New Relic sometimes spend more on monitoring than on the infrastructure they’re monitoring. We assess whether the cost is justified by the value and identify optimization opportunities.

Service Level Objectives, Error Budgets, and Distributed Tracing

A key component of our monitoring due diligence is assessing whether the target company has defined Service Level Objectives and the corresponding Service Level Indicators that measure them. SLOs represent a concrete commitment to reliability, and their presence or absence tells you a great deal about operational maturity.

We examine whether SLOs exist for customer-facing services and whether they are grounded in metrics that reflect actual user experience. A team that defines SLOs around server-side latency percentiles (p50, p95, p99) measured at the load balancer is in a strong position. A team that tracks only uptime as “the server is responding to health checks” may be missing degraded performance that frustrates users without triggering alerts.

Error budgets are the operational consequence of SLOs. We assess whether the team uses error budget policies to balance reliability investment against feature velocity. A mature team slows feature work when the error budget is exhausted and accelerates it when reliability is healthy. This practice indicates that reliability is treated as a product concern, not just an engineering one.

We also evaluate distributed tracing maturity. For microservice architectures, the ability to trace a request across service boundaries is essential for diagnosing latency and errors. We check whether traces are instrumented with OpenTelemetry or a vendor SDK, whether trace sampling rates are appropriate for the traffic volume, and whether engineers actually use traces during incident investigations. Tracing infrastructure that exists but goes unused is a cost without corresponding value.
