Result Data Plugins (Enterprise)

Result Data Plugins (Enterprise)

Available in PagerDuty Process Automation Commercial products.

This plugin allows Jobs to export a JSON file as the result of an execution, which will be stored alongside the output log file. The JSON file can be retrieved via the API as JSON data, and shown in the GUI.

This allows a Job to be executed, and a JSON result returned, customized to contain data that is relevant to the outcome of the Job.

There are currently two different Plugins that can be used to produce JSON data for a Job.

Requirements

Enable and configure one of these plugins in the Execution Lifecycle tab when editing a Job.

Configuration Tip

Currently, the data for this feature is stored as file based logs. To ensure resiliency please be sure that a LogStoreopen in new window is configured to backup the files.

Plugin: Result Data / Export Context

Provider name: result-data-export-context.

This plugin exports one or more data groups from the Global scope Execution Context into a JSON file.

The Execution Context is used to store data values as the Execution proceeds, and allows passing Captured data values from one step in a workflow to later steps in the workflow.

Data Groups are named key-value maps.

Tips

Typically, data is captured within Node Contexts, and in order to export the data it must be in a Global Context.

You can use the Key-Value Data Logfilter Pluginopen in new window to capture data into Node Contexts.

You can use the Global Variable Workflow Step Pluginopen in new window to copy Node Context data to the Global Context.

Inputs

Data Groups

Define the set of Groups to export into the JSON data.

Typically data captured using the "Key Value Data" Log Filter plugin, is put in the data group, and values can be referenced via ${data.mydata}. That data is also usually captured in the Node Context. Use the "Global Variable" workflow step to copy values out of Node context into the Global context, specifying what Group to put the values in. When exporting data values to parent Jobs in a multi-job workflow, it needs to be put in the export group.

The default Group to export is export, but a different one or multiple ones can be specified using a comma-separated list such as data,export.

The JSON data will be exported in the same structure it has in the stored context, such as:

{
	"export":{
		"mydata": "mydata value"
	}
}

Plugin: Result Data / JSON Template

Provider name: result-data-json-template.

This plugin exports a JSON document that is generated from a template defined by the user.

Execution Context data values can be used within Strings within the JSON document, and will be expanded as usually done within Commands and other steps, such as ${data.myvalue}.

The JSON Template also supports a special syntax for generating Arrays or Objects of data, by iterating over either the Node or Step context values.

For example, data captured using the "Key Value Data" Log filter on a command or script executed multiple Nodes will have a value for each node that executed.

This data can be copied as an Array or JSON Object (keyed by Node name) into the output document.

A Regular expression filter of Node Name can also be used, or specific Steps selected.

Inputs

JSON Template

Enter a valid JSON document. Context data values like ${data.name} or ${data.value@nodename} can be used within Strings. Note that Context Variable expansion is evaluated in a global context, meaning that ${data.name} will only work if there is a global value matching that group and name.

Simple Expansion

To include data captured from Node steps, such as when using the Key Value Data Log Filter, use a syntax like ${data.name*} which will collect all values for data.name in all Node contexts separated with a comma.

Example Template:

{ "key" : "${data.mydata*}" }

Result, expands into a comma-separated string for each Node:

{ "key" : "nodevalue1,nodevalue2" }

Example Using specific delimiter:

{ "key" : "${data.mydata*-}" }

Result, expands into a --separated string for each Node:

{ "key" : "nodevalue1-nodevalue2" }

Array Expansion

To expand all node values like that into a JSON array, use a special syntax:

{ "key": [], "key@": "data.name" }

This declares a map entry key as an array, and the key@ declares will collect all Node entries for data.name into the key value.

The result will be:

{ "key": ["nodevalue1","nodevalue2"] }

Object Expansion

To expand the data as a JSON Object instead, using Node Names as the map entries, declare the key entry as a JSON object:

{ "key" : {}, "key@": "data.name" }

The result will be:

{ "key" : {"node1": "nodevalue1", "node2": "nodevalue2" } }

Select a subset of node values using a syntax after the @ sign in the key:

  • key@~REGEX matches all nodes matching the regular expression

Similarly for Step values, select values based on the step key using this syntax:

  • *:key matches all steps
  • 1:key only step 1 value
{ "key" : [], "*:key": "data.name" }

Results in key value being an array of all Step data values for data.name.

A combination of *:key@ will enumerate all step and node values if there are different values in different steps.

A value of 1:key@ will match all node values in step 1.

API

The API can be used to check whether an Execution has a Result Data set, and to retrieve it.

Example Job

Here is a sample job provided in our Welcome Projects, that captures a set of values and uses the Result Data / JSON Template plugin to export the JSON:

Note: This requires installation of fortune command and the Rundeck CLI Toolopen in new window.
