# Temporal Cloud Metrics

> Monitor Temporal Cloud workloads with Cloud metrics and SDK metrics.

Temporal offers two distinct sources of metrics: [Cloud Metrics](/cloud/metrics/openmetrics/metrics-reference) and [SDK Metrics](/references/sdk-metrics).
Each source provides different levels of granularity, filtering options, monitoring-tool integrations, and configuration.

- **SDK metrics** monitor individual Workers and your code's behavior from the perspective of your application.
- **Cloud metrics** monitor Temporal Cloud's behavior from the perspective of the Temporal Service.

When used together, Cloud and SDK metrics measure the health and performance of your full Temporal infrastructure, including the Temporal Cloud Service and user-supplied Temporal Workers.

## Cloud Metrics

Cloud metrics for all Namespaces in your account are available from the [OpenMetrics endpoint](/cloud/metrics/openmetrics), a Prometheus-compatible scrapable endpoint at `metrics.temporal.io`.

Use the following rule of thumb when deciding which signal to rely on:

| Question | Primary signal |
|---|---|
| Is Temporal Cloud accepting and serving work normally? | Cloud metrics |
| Are Tasks backing up in a Task Queue? | Cloud metrics plus SDK Schedule-To-Start metrics |
| Are my Workers saturated, under-provisioned, or misconfigured? | SDK metrics |
| Is my application logic, downstream dependency, or Activity behavior unhealthy? | SDK metrics and traces |

For a Worker-focused view of how to combine these signals, see [Monitor worker health](/cloud/worker-health).

## SDK Metrics

SDK metrics are emitted by your Workers and Clients.
For setup instructions, see [SDK metrics setup](/cloud/metrics/sdk-metrics-setup).

## PromQL Endpoint (Deprecated) 

> **🚨 Danger:**
> PromQL endpoint deprecated
>
> The PromQL endpoint and its `temporal_cloud_v0_*` metrics were deprecated on April 2, 2026 and are no longer accepting new users.
> The PromQL endpoint will be disabled for all users on **October 5, 2026**.
>
> Migrate to the [OpenMetrics endpoint](/cloud/metrics/openmetrics).
> See the [migration guide](/cloud/metrics/openmetrics/migration-guide) for a complete v0-to-v1 metric mapping.

The legacy PromQL endpoint uses mTLS certificate authentication and exposes `temporal_cloud_v0_*` metrics via a Prometheus query API.
