How can I create a transforms.conf stanza from SplunkJS?

David — Tue, 31 Jan 2017 12:51:59 GMT

I want to create a new lookup file. In transforms.conf, that's pretty simple, it should look something like this:

[myLookup6]
filename = myLookup.csv

But how do I do that from SplunkJS?

I've found the appropriate docs, but haven't been able to divine the answer:
http://docs.splunk.com/DocumentationStatic/JavaScriptSDK/1.1/splunkjs.Service.Configurations.html
http://docs.splunk.com/DocumentationStatic/JavaScriptSDK/1.8.0/splunkjs.Service.ConfigurationFile.html
http://docs.splunk.com/DocumentationStatic/JavaScriptSDK/1.1/splunkjs.Service.ConfigurationStanza.html

After a lot of trial and error, and then the help of a partner who had done even more trial and error (and is a better programmer than me), I got the answer.

The overall process is:

Create a service object
Instantiate the configurations object with your scope (app, user, etc.)
Fetch the existing configurations for your file
Create a ConfigurationFile object with a blank config, or pull the existing one
With your file, create a new stanza

Here is the code that worked for me, on Splunk 6.5:

function dvtest(){
    var appscope={}
    appscope['owner'] = Splunk.util.getConfigValue("USERNAME");
    appscope['app'] = utils.getCurrentApp()
    appscope['sharing'] = "app"
    var mystanza = []
    mystanza['filename'] = "myLookup.csv"
    var svc = mvc.createService();
    var files = svc.configurations(appscope);
    var fileDeferred = $.Deferred();
    files.fetch({ 'search': 'name=transforms"' }, function(err, files) {
       var transformsFile = files.item("transforms");
       if (!transformsFile) {
           //  Create the file here
           transformsFile = files.create('transforms', function(err, transformsFile) {
              if (err) {
                  // Error case, throw an exception dialog to user here.
                  return;
              }
              fileDeferred.resolve(transformsFile);
           });
       }
       else {
          fileDeferred.resolve(transformsFile)
       }
    });
    fileDeferred.done(function(transformsFile) {
         transformsFile.create("myLookup6", mystanza, function(err, stanza) {
             // Stanza now created -- go check transforms.conf if you don't believe me
         }
    )});
}

Hi there David,

Please take a look at this example application that has been built.

Developer Guidance - Setup View Example For Splunk:
https://splunkbase.splunk.com/app/3728/

Source code can be found here:
https://github.com/splunk/Developer_Guidance_Setup_View_Example

This app uses a setup view to configure Splunk configuration files. While the goal is different, the solution is the same, and much of the code can be reused in the goal you're seeking to accomplish.

It is meant to serve as a point of reference.

Please let me know if that's not sufficient.
