How to import data to Splunk via HTTP GET request?

tamduong16 — Wed, 20 Sep 2017 14:26:47 GMT

I've been looking for a way to import contents from an http get request with Splunk without success. At first, I thought I could do this by using Rest Api section that build-in Splunk. But after I give it a url to do an http get request, my search return no event. I thought this is all I have to do to get content from the page to Splunk. The documentation for this section is very confusing and I don't know where to start. At this point, I don't know if Rest Api is the answer to my question. Does anyone know of a way I could get content with an http get request in Splunk?

Did your search return anything at all? Normally, with the API you run a search and the query returns a search SID, then you use the SID to query again for the results of the search.

You would usually build your search as a set of parameters and pass it to an endpoint, and get a SID back from that. Here's an example snippet from some python code I wrote to get bucket info from a dbinspect search:

 params = "search=%7Cdbinspect%20index%3D%2A%20latest%3Dnow%20earliest%3D-99y&exec_mode=blocking"
 url = "https://" + searchhead + ":8089/services/search/jobs/"
 item = json.loads(fetchdata(url,params))
 try:
     sid = str(item['sid'])
 except:
     sys.exit(1)
 url = "https://" + searchhead + ":8089/services/search/jobs/" + sid + "/results/"
 urldata = fetchdata(url)

You can see the query is in the params variable, and I pass it to the search head (the url variable) as a query parameter (the fetchdata call). the result is returned to the item[] array which I grab the SID from (the try block: sid = str item['sid']).
Once I have the SID I build a new url var with the SID (second from last line in the example) then call it to return the result data.

in addition you can use workflow actions and alerts to GET / POST http actions as well. Remember, the REST api will poll the GET url continuously at the polling interval. Suggest read up workflow and alert actions as well, but what @sjalexander is asking is most important - if your rest api integration is not working and not fetching a SID then it could be that you have missed some configuration, are you sure you have passed the tokens / keys needed to fetch data from your GET url? Mostly all api urls will have some authentication mechanism....
