# Observability

> Monitor activity and performance.

Monitor activity and performance.

Use project queries for individual applications. Use [account analytics](/docs/cloud/rest/apis/billing-usage#analytics) to inspect conversation activity across the account, and [Runs](/docs/cloud/rest/apis/orchestration) for account run analytics.

[Logs](#logs) · [Traces](#traces) · [Metrics](#metrics) · [Alerts](#alerts) · [Error types](#error-types)

## Logs

Query project logs to investigate activity and failures. Each endpoint reference lists the supported filters.

| Endpoint | Methods | Description |
| - | - | - |
| `/projects/{project_reference}/logs` | [GET](/docs/cloud/rest/api-reference/observability-logs-log-entries/list-log-entries) | List log entries |

## Traces

Find project traces and inspect individual traces by ID. Trace spans connect related execution activity. For a run’s event history, use the [run endpoints](/docs/cloud/rest/apis/orchestration).

| Endpoint | Methods | Description |
| - | - | - |
| `/projects/{project_reference}/traces/{trace_id}/spans` | [GET](/docs/cloud/rest/api-reference/observability-traces-trace-spans/list-trace-spans) | List trace spans |
| `/projects/{project_reference}/traces/{trace_id}` | [GET](/docs/cloud/rest/api-reference/observability-traces-project-traces/get-trace) | Get trace |
| `/projects/{project_reference}/traces` | [GET](/docs/cloud/rest/api-reference/observability-traces-trace-search/query-traces) | Query traces |

## Metrics

Query project metrics to inspect measurements over time.

| Endpoint | Methods | Description |
| - | - | - |
| `/projects/{project_reference}/metrics/query` | [POST](/docs/cloud/rest/api-reference/observability-metrics-metric-series/query-metrics) | Query metrics |

## Alerts

List the alerts that fired for a project, firing and recently resolved, with links to the logs and traces they cover.

| Endpoint | Methods | Description |
| - | - | - |
| `/projects/{project_reference}/alerts` | [GET](/docs/cloud/rest/api-reference/observability-alerts-project-alerts/list-alerts) | List alerts |

## Error types

Read the meaning of a published error type. Use [logs](/docs/cloud/rest/apis/observability#logs) or [traces](/docs/cloud/rest/apis/observability#traces) to investigate a specific failed request.

| Endpoint | Methods | Description |
| - | - | - |
| `/errors` | [GET](/docs/cloud/rest/api-reference/observability-error-types-error-types/list-error-types) | List error types |
| `/errors/{error_type_slug}` | [GET](/docs/cloud/rest/api-reference/observability-error-types-error-types/get-error-type) | Get error type |
