> Monitor Temporal Cloud service health and Worker health, and receive operational notifications.

Monitor Temporal Cloud and the Workers connected to it to detect service issues, Task Queue backlogs, and Worker
capacity problems.

Temporal provides Cloud metrics, SDK metrics, health-monitoring guidance, and notifications. Use the following guides
based on what you need to detect.

## Choose what to monitor

| Goal | Guide | What it helps you detect |
| --- | --- | --- |
| Collect metrics from Temporal Cloud and your Workers | [Set up metrics](/cloud/metrics) | Service, Task Queue, Worker, and Client behavior |
| Monitor Temporal Cloud service health | [Monitor service health](/cloud/service-health) | Service latency and errors, Workflow and Activity failure trends, throttling, and capacity limits |
| Monitor Workers connected to Temporal Cloud | [Monitor Worker health](/cloud/worker-health) | Task backlogs, insufficient or excess Worker capacity, configuration problems, and Worker availability |
| Receive operational updates | [Receive notifications](/cloud/notifications) | Temporal Cloud incidents, expiring credentials, billing events, and completed or failed failovers |

## Understand metric sources

Temporal provides two complementary metric sources:

- **Cloud metrics** show what the Temporal Service observes, including request latency, service errors, Task Queue
  behavior, throttling, and Namespace-level activity.
- **SDK metrics** show what your Workers and Clients observe, including Schedule-To-Start latency, available Worker
  slots, cache behavior, and request failures.

Use both sources to distinguish a Temporal Cloud service issue from a Worker or application issue.

To begin collecting metrics:

1. [Set up Cloud metrics with OpenMetrics](/cloud/metrics/openmetrics).
2. [Connect Temporal Cloud to your observability tool](/cloud/metrics/openmetrics/metrics-integrations).
3. [Set up SDK metrics](/cloud/metrics/sdk-metrics-setup).
4. Use the [service health](/cloud/service-health) and [Worker health](/cloud/worker-health) guides to create monitors and
   alerts.

## Monitor Nexus

To monitor Nexus metrics and debug Nexus Operations, see [Temporal Nexus observability](/cloud/nexus/observability).

For records of Control Plane changes, see [Audit Logs](/cloud/audit-logs). Audit Logs answer who changed a Temporal
Cloud resource, what they changed, and when. They are separate from runtime health monitoring.
