Example

const { checkhelper, healthcheck } = require('mxd-healthcheck')(config, app);

const services = {};
healthcheck(services);

Services

List of check functions for the external services

const service = (callback) => {
  if (/* check if the external dependency is available like needed */) {
    callback();
  } else {
    callback(/* reason why the external dependency is not OK */);
  }
}

checkhelpers

Check functions for some common external services

BBE (= MMW)

const service = checkhelper.bbe(/* connection config */);

Healthcheck App (= Bifrost, Heimdall, Skidbladnir)

const service = checkhelper.healthcheckApp(/* connection config */);

Interfacemanager (= MMW-Proxy, = API)

const service = checkhelper.interfacemanager(/* connection config */);
