Use the ProbeHealth service to test Mobile Access

Mobile Access includes a ProbeHealth service that you can use to test the status and availability of the server.

Each instance of Mobile Access includes its own ProbeHealth service that returns HTTP status codes when queried.

To access the ProbeHealth service for a given instance, configure your load balancer to go to the following URL:

https://<host name or IP address>/<VersionNumber>/ProbeHealth

Example for the default version of Mobile Access:

https://scadaserver01/MA/ProbeHealth

Example for a specific version of Mobile Access:

https://scadaserver01/AVEVAEdge2026/ProbeHealth

For more information about linking to a specific version of Mobile Access, see Link directly to a project screen or screen group. However, the ProbeHealth service is a recent addition to Mobile Access and is not included in some earlier versions, so make sure you test the configuration of the server before you allow it to accept connections from users.

The ProbeHealth service returns one of the following HTTP status codes when queried:

Additional information is provided as a JSON-formatted message, which can be used for logging or troubleshooting purposes. That message should include one of the following result codes:

Examples of messages:

{"id":0,"resultCode":0,"message":"","data":{"probeHealth":"Ok!"}}

{"id":0,"resultCode":305,"message":"WebProxy: Error to create connection, please make sure the runtime is running and that the Mobile Access Task is started (see Project->Tasks). [status: -13, message: Fail to establish connection, data: Error to establish connection [OS Error Code: 10061]]","data":{}}
