Health (health
)
The health
endpoint provides detailed information about the health of the application.
Retrieving the Health of the Application
To retrieve the health of the application, make a GET
request to /actuator/health
, as shown in the following curl-based example:
$ curl 'http://localhost:8080/actuator/health' -i -X GET \
-H 'Accept: application/json'

|
|
Overall status of the application. |
|
|
The components that make up the health. |
|
|
Status of a specific part of the application. |
|
|

|
|
Details of the health of a specific part of the application. Presence is controlled by |

Retrieving the Health of a Component
To retrieve the health of a particular component of the application’s health, make a GET
request to /actuator/health/{component}
, as shown in the following curl-based example:
$ curl 'http://localhost:8080/actuator/health/db' -i -X GET \
-H 'Accept: application/json'
The resulting response is similar to the following:
HTTP/1.1 200 OK
Content-Type: application/json

}
}
Response Structure
The response contains details of the health of a particular component of the application’s health. The following table describes the structure of the response:
Path | Type | Description |
---|---|---|
|
|
Status of a specific part of the application |
|
|
Details of the health of a specific part of the application. |
Retrieving the Health of a Nested Component
If a particular component contains other nested components (as the broker
indicator in the example above), the health of such a nested component can be retrieved by issuing a GET
request to /actuator/health/{component}/{subcomponent}
, as shown in the following curl-based example:
$ curl 'http://localhost:8080/actuator/health/broker/us1' -i -X GET \
-H 'Accept: application/json'
The resulting response is similar to the following:
HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: 66
{
"status" : "UP",
"details" : {
"version" : "1.0.2"
}
}
Components of an application’s health may be nested arbitrarily deep depending on the application’s health indicators and how they have been grouped.
The health endpoint supports any number of /{component}
identifiers in the URL to allow the health of a component at any depth to be retrieved.
Response Structure
The response contains details of the health of an instance of a particular component of the application. The following table describes the structure of the response:
Path | Type | Description |
---|---|---|
|
