Application Performance Monitoring

Infrastructure can look perfectly healthy while the application running on it is slow, throwing errors, or timing out for a subset of users. APM instruments the application layer itself — transactions, dependencies, and error rates — so performance problems get traced to the specific code path and service causing them.

Infrastructure metrics answer “is the server healthy?” APM answers a different and often more urgent question: “is the application actually working for the person using it?” A checkout flow that times out on a third-party payment call, an API endpoint with a slow database query buried three services deep, a background job silently failing — these are application-layer problems that infrastructure dashboards routinely miss.

Armorstack’s APM service instruments your applications for distributed tracing, mapping every transaction across the services and dependencies it touches, and tracks latency and error rate at the endpoint level rather than just the aggregate. For applications with third-party integrations — payment processors, identity providers, external APIs — APM makes clear when a slowdown originates outside your own infrastructure, which matters both operationally and when it’s time to have that conversation with a vendor.

For regulated environments, APM also produces the kind of granular audit trail that supports uptime and availability commitments under frameworks like SOC 2’s Availability criterion.

What’s Included

APM data flows into the same unified observability platform as infrastructure and security telemetry, and benefits from the correlation Armorstack builds in AIOps.
