                        status: 'healthy', // status of 'healty' indicates monitor is healthy, any other value indicates monitor failure and will cause the top-level status to change to 'faulting'
                        name: 'monitor 1', // optional name, useful for differentiating between monitors
                        myField1: true,    // arbitraty fields, usefull for surfacing
