An inference service is not a web application. It has its own failure modes, its own cost drivers and its own definition of working. Observability for AI workloads answers the questions AI operations teams actually ask, and it should be designed before the workload goes live, not after the first quiet failure.
What goes wrong
The model endpoint reports healthy while returning poor answers. Latency looks fine on average and terrible at the tail, which is where users live. Retrieval pipelines silently return stale or irrelevant context. Agents call tools in loops nobody can see. Token consumption grows and nobody knows which workload is responsible. Traditional uptime monitoring says everything is green.
How C4C approaches it · Cause
Treat the inference path as a trace like any other: prompt in, retrieval, model call, tool calls, response out, with timing and token cost at each hop. Add quality signals alongside performance signals, so a degradation in answer quality is visible as early as a degradation in latency. Tie workload telemetry back to the infrastructure it runs on, so a saturated accelerator shows up as the cause of a slow response rather than a separate alert. Designed to sit alongside C4C Validated Designs and AI Pods, so the observability is part of the reference architecture rather than an afterthought.
What you instrument and how deep. Full depth, infrastructure only, or discovered but not monitored, decided on purpose for every part of the estate.
The topology and the business meaning attached to the telemetry, so a technical signal arrives already attached to its consequence.
Getting from symptom to root cause in minutes rather than hours. One problem, one cause, the owner obvious. It only works when Coverage and Context are right.

Questions
The service can be up and fast while producing wrong answers. Observability for AI adds quality signals alongside performance ones, follows the full path from prompt to response including retrieval and tool calls, and attributes token and compute cost to each workload.
Usually not. The inference path is a trace, and it runs on infrastructure the organisation already observes. Designing AI workload observability into the existing platform keeps one picture of the estate and lets an infrastructure cause show up against an AI symptom.
Before the workload goes live. AI failures are often quiet, so the first sign of a problem in an unobserved workload is usually a user telling you, some time after it started.
An hour with the practice, no slides, no obligation. Bring your incident history and your tooling list. Leave with a plain view of where your observability is working, where it is not, and what to do first.
