/sys/health

The /sys/health endpoint is used to check the health status of Vault.

Read health information

This endpoint returns the health status of Vault. This matches the semantics of a Consul HTTP health check and provides a simple way to monitor the health of a Vault instance.

The default status codes are:

• 200 if initialized, unsealed, and active
• 429 if unsealed and standby
• 472 if disaster recovery mode replication secondary and active
• 473 if performance standby
• 501 if not initialized
• 503 if sealed

Parameters

• standbyok (bool: false) – Specifies if being a standby should still return the active status code instead of the standby status code. This is useful when Vault is behind a non-configurable load balancer that just wants a 200-level response. This will not apply if the node is a performance standby.

• perfstandbyok (bool: false) – Specifies if being a performance standby should still return the active status code instead of the performance standby status code. This is useful when Vault is behind a non-configurable load balancer that just wants a 200-level response.

• activecode (int: 200) – Specifies the status code that should be returned for an active node.

• standbycode (int: 429) – Specifies the status code that should be returned for a standby node.

• drsecondarycode (int: 472) – Specifies the status code that should be returned for a DR secondary node.

• performancestandbycode (int: 473) – Specifies the status code that should be returned for a performance standby node.

• sealedcode (int: 503) – Specifies the status code that should be returned for a sealed node.

• uninitcode (int: 501) – Specifies the status code that should be returned for a uninitialized node.

Sample request

$ curl \
    http://127.0.0.1:8200/v1/sys/health

Sample response

This response is only returned for a GET request.

Note: replication_performance_mode and replication_dr_mode reflect the state of the active node in the cluster; if you are querying it for a standby that has just come up, it can take a small time for the active node to inform the standby of its status.
