Properties
InputPathsMap
Map of JSON paths to be extracted from the event.
virtual object InputPathsMap { get; }
Property Value
System.Object
Remarks
You can then insert these in the template in InputTemplate
to produce the output you want to be sent to the target.
InputPathsMap
is an array key-value pairs, where each value is a valid JSON path. You can have as many as 100 key-value pairs. You must use JSON dot notation, not bracket notation.
The keys cannot start with " AWS ."
InputTemplate
Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap
to customize the data sent to the target.
string InputTemplate { get; }
Property Value
System.String
Remarks
Enclose each InputPathsMaps
value in brackets: < value >
If InputTemplate
is a JSON object (surrounded by curly braces), the following restrictions apply:
The following example shows the syntax for using InputPathsMap
and InputTemplate
.
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state <status>"
}
To have the InputTemplate
include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": "<instance> is in state "<status>""
}
The InputTemplate
can also be valid JSON with varibles in quotes or out, as in the following example:
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},
"InputTemplate": '{"myInstance": <instance>,"myStatus": "<instance> is in state "<status>""}'
}
