SSL test metrics

A run is one execution of a Synthetics test from a specific device at a specific location. The default test metrics are automatically created for each test. The following metrics are derived from each run:

Metric Metric name Description
Connection time synthetics.connect.time.ms The duration of TCP connection time in milliseconds.
Days until expiration synthetics.ssl.expire.days

Expired certificates will have the value of 0, and negative values are converted to 0.

Values will be always be floored to cover scenarios when the value is < 1 and for all decimal numbers.
DNS time synthetics.dns.time.ms The duration of DNS translation time in milliseconds.
Downtime (Default) synthetics.run.downtime.percent For failed tests, the value will be 100.0. Successful tests will have the value of 0.0.
Duration (Default) synthetics.duration.time.ms A copy of synthetics.run.duration.time.ms.
Run count (Default) synthetics.run.count In most cases, the value will be 1.
Run duration synthetics.run.duration.time.ms The duration of an entire test in milliseconds from start to end.
TLS time synthetics.tls.time.ms The duration of TLS handshake time in milliseconds.
Uptime (Default) synthetics.run.uptime.percent 100.0 = Test Successful

0.0 = Test Failed

For successful tests, the value will be 100.0. Failed tests will have the value of 0.0.
