Analyzer

A single analyzer to run on the collect spec. An analyzer is comprised of registerVariables and evaluateConditions to display an insight on failure or success.

Optional Parameters

• ‘name’ - The name of the analyzer

• ‘labels’ - Key, value pairs used to organize and identify the analyzer

• ‘insight’ - The insight to be displayed upon success spec

• ‘registerVariables’ - A list of variables to register, can be used in evaluateConditions expressions spec

• ‘evaluateConditions’ - A list of conditions to evaluate in order spec

Usage

An example is shown below for the ‘os.ubuntu’ analyzer.

analyze:
  v1:
    - name: os.ubuntu
      insight:
        primary: OS is Ubuntu
        detail: Operating System is Ubuntu
        severity: info
      registerVariables:
        - name: os
          os: {}
      evaluateConditions:
        - condition:
            stringCompare:
              eq: ubuntu
            variableRef: os
          insightOnError:
            primary: Failed to detect OS
            detail: Operating System is Ubuntu
            severity: debug
          insightOnFalse:
            primary: OS is not Ubuntu
            detail: Operating System is not Ubuntu
            severity: debug

Insight

An insight represents information to be surfaced to the user upon analysis. It consists of a primary and detailed message as well as a severity.

Required Parameters

• ‘primary’ - A short message to display to the user

• ‘detail’ - A detailed message to display to the user

Optional Parameters

• ‘name’ - The name of the insight

• ‘labels’ - Key, value pairs used to organize and identify the insight

• ‘severity’ - The severity of the insight (default info)

Variable

A variable registered by name. Information can be extracted into the variable and used in conditions to surface insights. For a list of variables see here.

Required Parameters

• ‘name’ - The name of the variable

Optional Parameters

• ‘labels’ - Key, value pairs used to organize and identify the variable

EvaluateCondition

A condition to be evaluated and surface an insight. Conditions will be evaluated in order. An error or failure will halt execution. Insights can be specified to display in these cases (insightOnError, insightOnFalse).

Required Parameters

• ‘condition’ - The condition to be evaluated spec

Optional Parameters

• ‘name’ - The name of the condition

• ‘labels’ - Key, value pairs used to organize and identify the condition

• ‘insightOnError’ - The insight to be displayed when the condition results in an error

• ‘insightOnFalse’ - The insight to be displayed when the condition evaluates to false

Condition

A condition that results in true, false, or an error. For a list of conditions see here.

Optional Parameters

• ‘name’ - The name of the condition

• ‘labels’ - Key, value pairs used to organize and identify the condition

• ‘variableRef’ - The input variable to the condition.
