Snap type:

Read


Description:

This Snap executes a search query and retrieves data from Splunk using the Splunk REST API.

  • Expected upstream SnapsUpstream Snap is optional. Any Snap with a document output view can be connected upstream.
  • Expected downstream SnapsAny Snap with a document input view can be connected downstream, such as Mapper, CSV Formatter, JSON Formatter, XML Formatter or Structure.
  • Expected inputThe Snap does not require input data. Input documents may be used to evaluate any JavaScript expression in the properties.
  • Expected output: The search result received from Splunk is in XML format. The Snap parses this XML data and produces a stream of documents at the output view. An example of the output preview on the Search query property value of "search * | head 2" is as follows:

The search output includes both, preview data from a search that is still in progress, indicated by “_preview“:true, and the actual data after the search completes, indicated by “_preview“:false. You must use a Filter Snap next, to specify which of these data must be fed into downstream Snaps. To do this, in the Filter expression field of the Filter Snap, specify the value of the preview field as:

  • false, to use the actual results after the search completes. 

  • true, to use a preview or partial result of a search that is still in progress. This is helpful in case of long searches. In addition, you can provide an offset value to indicate the serial number starting from which the records must be selected. For example, if offset is specified as 50, the preview result starting from the 50th record are used. 

Note

Preview data is cumulative, therefore, it may include duplicate records from previous previews, if any.  


Prerequisites:

[None]


Support and limitations:Works in Ultra Task Pipelines.
Account: 

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. The Snap requires a Splunk basic auth account.


Views:


InputThis Snap has exactly one document input view. It may contain values to evaluate the JavaScript expression in the File property.
OutputThis Snap has exactly one document output view and provides the document data stream for the search result.
Error

This Snap has at most one document error view and produces zero or more documents in the view. If the Snap fails during the search operation, an error document is sent to the error view containing the fields error, reason, resolution, and stacktrace:

Code Block
{
        "error": "Failed to get search result",
        "reason": "Invalid search query or  <an error message from Splunk>",
        "resolution": "Please check for valid Snap properties."
        "stacktrace":"com.Snaplogic.Snap.api.SnapDataException:  ... "
}
