Prime Infrastructure API list of "appId"

[pematthe]

In the PI API, specifically the "GET statisticsService" area there is a query switch to list appId.  "The application Id. Use comma to seperate multiple ids."

The example shows appId 1234 and 5678 which obviously does not work. - does anybody know how to list the known applicationIDs?  Is there an API call to list the appId?  

The reason, and it could be I am looking in the wrong place for the information I need, is that I want to be able to list the application traffic by volume and the the bit/bytes for each network application (ssl, http, ms-services etc.etc.etc.) but I would like to list an application and find out how many clients are generating it.  ssl = 20 clients, https = 90 clients, apple-services=15 clients - that sort of thing.

GET Application Top N Traffics

Retrieves the top N clients or server traffic statistics of an application or all applications. Here are the sample queries /op/statisticsService/application/topNTraffics -- return the top 15 client traffics of all applications in the past 1 hour /op/statisticsService/application/topNTraffics?nodeType=server -- return the top 15 server traffics of all applications in the past 1 hour /op/statisticsService/application/topNTraffics?networkAwareType=2 -- return the top 15 client wired traffics of all applications in the past 1 hour /op/statisticsService/application/topNTraffics?appId=1234 -- return the top 15 client traffics of the application with id 1234 in the past 1 hour /op/statisticsService/application/topNTraffics?appId=1234,5678 -- return the top 15 client traffics of of the application with id 1234 and 5678 in the past 1 hour M.

Yes, this is from the documentation.  I am looking to find a way of finding the list of the 'appID' values to use in the URL.  I have tried using the appIDs from the NBAR2 application list on the WLC - 

(Cisco Controller) >show avc applications

Application-Name App-ID Engine-ID Selector-ID Application-Group-Name
================ ====== ========= =========== ======================
3com-amp3      538      3      629 other
3com-tsmux     977      3      106 obsolete
3pc                   788      1      34

etc.

but that doesn't get any values back for application I know have traffic.

  - Which version of Prime are you using ?

M.

[pematthe]

PI 3.1

[marce1000]

 - There are a number of resolved caveats in the 3.2 Release Notes concerning  the API ; the most notable on I see for the moment is :

CSCuz60426

Intermittent 401 and 403 errors when accessing Prime Infrastructure API.

                - As usual, worth trying, but you need to allocate time in order to upgrade

I'm not seeing error 401,403. I just cannot use the 'appID' switch in the URL to get useful values back as I don't know what 'appID' to use. Without filtering, 'appId=0' I get:
<mgmtResponse responseType="operation" requestUrl="https://192.168.xx.yy/webacs/api/v1/op/statisticsService/application/trafficAnalysis?range=1&amp;type=1&amp;appId=0" rootUrl="https://192.168.xx.yy/webacs/api/v1/op">

If I use appId 1234 or any other 4 digit combination, the response is similar format but there are no values provided or values = 0

 - Do you have application visibility enabled for the particular SSID's on the controller;

 - Perhaps Prime needs sufficient licensing and or do you have an Assurance license for cisco prime ?

M.

[pematthe]

Yes, AVC is enabled. In other Prime API calls I can get a list of applications by name and the data seen. The info is there, I just cannot get a response via the 'appId' query.
