# HEALTH METRICS

> Track requests, errors, latency, and token throughput for every managed deployment

## OVERVIEW

The Oumi Agent can read your deployment's operational health on demand. Ask how a deployment is doing and it reports traffic volume, error rate, latency percentiles, and token throughput, then pairs that with [quality monitoring](/guides/deployment/monitoring) scores to tell you whether a problem is operational or a real quality regression.

The same data lives on the deployment's **Health** tab, so you get serving observability without wiring up an external metrics stack. Every managed deployment with [inference logging](/guides/deployment/inference-logs) enabled reports health metrics automatically.

***

## THE HEALTH TAB

Open a deployment and select the **Health** tab. A summary row shows the numbers for the visible window:

| Metric                 | What it tells you                                                 |
| ---------------------- | ----------------------------------------------------------------- |
| **Requests**           | Total requests served in the window.                              |
| **Avg Requests / min** | Request rate over the window.                                     |
| **Error Rate**         | Share of requests that failed, with the raw error count on hover. |
| **Latency (p50)**      | Median end-to-end response time.                                  |
| **Latency (p95)**      | Response time of the slowest 5% of requests.                      |

Below it, five charts break the window into time buckets:

| Chart                        | Series                                                    |
| ---------------------------- | --------------------------------------------------------- |
| **Requests**                 | Request count per bucket.                                 |
| **Request Latency (ms)**     | P50, P95, and P99 end-to-end latency.                     |
| **Time to First Token (ms)** | P50, P95, and P99 time until the first token is returned. |
| **Token Throughput (tok/s)** | Input and output tokens per second.                       |
| **Error Rate (%)**           | Failed request share per bucket.                          |

The **Time window** selector zooms from 1 hour out to 30 days, with a `Custom` option for an exact range. The tab shows up to 30 days of history. Charts support pan and zoom, and each card can be refreshed, expanded, or saved.
