security posture score

Synonyms: posture score, compliance score

Available for Cloud Security Management Misconfigurations, the security posture score represents the percentage of your environment that satisfies all of your active Datadog out-of-the-box Cloud and Infrastructure compliance rules.

Formula:

$${{({\text"Pcrictical"/\text"Pcritical + Fcritical"})^2 *8}+{(\text"Phigh"/\text"Phigh + Fhigh") *6}+{(\text"Pmedium"/\text"Pmedium + Fmedium") *3}+{(\text"Plow"/\text"Plow + Flow") *2}+{(\text"Pinfo"/\text"Pinfo + Finfo") *1}}/{8+6+3+2+1}$$

• P is the number of misconfigurations that evaluate to pass.
• F is the number of misconfigurations that evaluate to fail.

The formula uses a weighted ratio that considers the severity of the misconfiguration and the number of pass/fail misconfigurations for each severity. Only rules and misconfigurations that have the tag scored:true are included in the calculation.

If there are no misconfigurations for a given severity, the severity is not included in the calculation. For example, if there are no critical misconfigurations, the denominators would be 6+3+2+1 (excluding 8 for critical).

You can improve your score by remediating misconfigurations, either by fixing the underlying issues or by muting the misconfiguration for the impacted resource. The posture score is updated every hour.

test regression

Related terms: performance regression

In Datadog CI Test Visibility, a test run is marked as a regression when its duration is both five times the mean and greater than the max duration for the same test in the default branch. Additionally, the test run must have a minimum duration of 500ms to be considered a regression. A benchmark test run (@test.type:benchmark) is marked as a regression when its duration is five times the standard deviation above the mean for the same test in the default branch.

The mean and maximum durations of the default branch are calculated based on the test runs from the past week. For the algorithm to consider a test run, there must be a minimum of 100 test runs on the default branch. For benchmark test runs, the minimum number of test runs is 10. For more information, see the documentation.

test run

trace

A trace tracks the time spent processing a request, and the status of this request. Each trace consists of one or more spans.

trace context propagation

Trace context propagation is the method of passing trace identifiers between services in a distributed system. It enables Datadog to stitch together individual spans from different services into a single distributed trace. Trace context propagation works by injecting identifiers, such as the trace ID and parent span ID, into HTTP headers as the request flows through the system. The downstream service then extracts these identifiers and continues the trace. This allows the Datadog to reconstruct the full path of a request across multiple services.

For more information, see propagating the trace context for your application’s language.

trace ID

The trace ID is a numerical identifier generated by the tracing library for a trace. Together with span IDs, they are used to correlate traces and logs in Datadog.

trace metric

Trace metrics are automatically collected and kept with a 15-month retention policy similar to any other Datadog metric. They can be used to identify and alert on hits, errors, or latency. Statistics and metrics are always calculated based on all traces, and are not impacted by ingestion controls.

Trace metrics are tagged by the host receiving traces along with the service or resource. For example, after instrumenting a web service trace metrics are collected for the entry-point span web.request on the Metrics Summary page.

Trace metrics can be exported to a dashboard from the Service or Resource page. Additionally, trace metrics can be queried from an existing dashboard.

Trace metrics are useful for monitoring. APM monitors can be set up on the New Monitors, Service, or Resource page. A set of suggested monitors is available on the Service or Resource page.

trace root span

A span is a trace root span when it is the first span of a trace. The root span is the entry-point method of the traced request. Its start marks the beginning of the trace.

In this example, the service entry spans are:

• rack.request (which is also the root span)
• aspnet_coremvc.request
• The topmost green span below aspnet_coremvc.request
• Every orange mongodb span
