Supported Metrics

Metric NameDescriptionUnits
availability.down.location.count

Location Count. The number of locations where the configured host is down-
synthetic.response.time

Response time. Duration to do the configured HTTP Method (GET, POST, PUT, HEAD) to specified URLmilliseconds
synthetic.response.lookuptime

Name Lookup Time. Duration from the start until the DNS name is resolved.milliseconds
synthetic.response.connecttime

Connection Time. Duration from the start until the web server is connected.milliseconds
synthetic.response.appconnecttime

AppConnect Time. Duration from start until SSL/SSH handshake is completedmilliseconds

synthetic.response.code

The synthetic.response.code metric captures the HTTP response codes returned by the monitored server during synthetic transactions. If the server is unreachable or the request fails, this metric will display a value of 0. This metric remains available even when the Location Availability feature is down.
