By default, Relay rejects data on project ID mismatch. Set this setting to `true` when Relay redirects traffic to a migrated Sentry instance, such as when moving from self-hosted to Sentry SaaS. Validation of project identifiers can be safely omitted in these cases, and you can continue to use the previous DSNs in your services. |
 
+## Health
+
+Settings to control Relay's health checks.
+
+After breaching one of the configured thresholds, Relay will
+return an `unhealthy` status from its health endpoint.

+| probe_timeout_ms          | Integer | default: 900 | Health check probe timeout in milliseconds. Any probe exceeding the timeout will be considered failed. This limits the max execution time of Relay health checks. |

Only applies when `spool.envelopes.path` is set. This value should be lower than `health.max_memory_percent` to prevent flip-flopping. |
