Client Failover Service

Health endpoints

  • Last UpdatedFeb 20, 2025
  • 3 minute read

You can configure Client Failover Service to produce and store health data at a designated health endpoint. You can use health data to ensure that your Client Failover Service is running properly and that data flows to the configured OMF endpoints.

Configure health endpoint

A health endpoint designates an OMF endpoint where adapter health information is sent. You can configure multiple health endpoints.

Complete the following steps to configure health endpoints. Use the PUT method in conjunction with the https://<host>:<port>/api/v1/configuration/healthendpoints REST endpoint to initialize the configuration.

  1. Using a text editor, create an empty text file.

  2. Copy and paste an example configuration for health endpoints into the file.

    For sample JSON, see the examples section below.

  3. Update the example JSON parameters for your environment.

    For a table of all available parameters, refer to the Health endpoint parameters section.

  4. Save the file as a json file. For example, as ConfigureHealthEndpoints.json.

  5. Open a command line session. Change directory to the location of the saved file from the previous step.

  6. Enter the following cURL command (which uses the PUT method) to initialize the health endpoint configuration.

    curl -i -k -u <username>:<password> -d "@<json file name>.json" -H "Content-Type: application/json" -X PUT "https://<host>:<port>/api/v1/configuration/healthendpoints"

For additional information on the curl parameters, such as -i or -k, refer to the Configuration tools section.

Note: For a list of other REST operations you can perform, like updating or replacing a health endpoints configuration, see Health endpoints.

Health endpoint parameters

The following parameters are available for configuring health endpoints:

Parameter

Required

Type

Description

id

Optional for POST, required for PUT

string

Uniquely identifies the endpoint. This can be any alphanumeric string. If left blank, a unique value is generated automatically.

string

The URL of the OMF endpoint to receive this health data.

Allowed value: well-formed http or https endpoint string

Default: null

username

Optional for PI Web API endpoints

string

The username used to authenticate with a PI Web API OMF endpoint.

PI server:

Allowed value: any string

Default: null

Note: The property pair Username/Password is only for basic authentication with PI Web API. The pair ClientId/ClientSecret is only for authentication with CONNECT data services. For PI Web API, if Username/Password are omitted, then Kerberos/NTLM is used instead.

password
