How to configure the Splunk Rest Modular Input to get data?
I'm attempting to get some data out of an EMC Unity Array. Using the Restlet Chrome Extension, I can get valid data back with this URL:
https://IP/api/types/metricValue/instances?filter=path eq "sp.*.cpu.summary.utilization" &per_page=1
When I configure the REST Modular Input the same way, I get no data basically. Here is what I receive:
<!DOCTYPE html><html><head><meta http-equiv="Cache-Control" content="no-store"; charset=UTF-8 > <script type="text/javascript">function getUrlVars(location) { var vars = [], hash; var hashes = location.href.slice(location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++){ hash = hashes[i].split('='); vars[hash[0]] = hash[1]; } return vars;}var winlocation = window.location;var hrefSplit = winlocation.href.split('#'); var destloc = '/misc/index.jsp' + '?' + 'url=' + encodeURIComponent(hrefSplit[0])+'&'+'hash='+encodeURIComponent(hrefSplit[1]);var casHomeValue=getUrlVars(winlocation)['casHome'];if (casHomeValue) { destloc += '&' +'casHome'+'='+encodeURIComponent(casHomeValue);}window.location=destloc;</script></head></html>
The documentation is pretty slim, so I'm assuming I'm doing it wrong. Any ideas?

Have you installed this app? If so, then have you configured your endpoint correctly?

I had to do that same thing. You have to point to a specific argument. The question is, were you able to get the sp..storage.lun..currentIOCount? I have been struggling trying to get the correct URL to pull that data.

That's the app I'm using, and that is returning the data I provided in the original post. I'm using the GUI to input the parameters for the REST API of the EMC Unity array.

You should try something simple to test it out. You can grab a test API string from Google and verify its working as expected. Next, you should try doing a simple CURL with your api string to verify its working as expected

I could only get this working by putting the URL to the metric I'm wanting to track in the Endpoint URL field. If I put the base IP in the URL, and then added URL arguments, it wouldn't work.
I'm not sure why this is the case 😕

It works when I test it via a little Chrome extension. So I know the permissions are correct, and the URL parameters are correct. So, I'm assuming I'm just not putting it in correctly in the app 😕 However, there is no indication in splunkd.log of a mis-configuration, so I'm not sure.
If I login to the EMC console in Chrome, and then bring up Restlet, and perform a GET against https://ip/api/types/metricValue/instances?filter=path eq "sp.*.cpu.summary.utilization" &per_page=1 I receive the json format return I'm expecting.
