View source for Umlaut SFX statistics gotchas

[[Category:Umlaut]]

Okay, there are a couple gotchas with your SFX statistics reports when you are using Umlaut. These are really problems/issues with any SFX API use, they are not unique to Umlaut. 

If you're using Umlaut, all link resolver menu displays that go 
through Umlaut will make it to SFX as "API" requests. This has two 
consequences:

== Include multi_obj_xml format ==

In your SFX report generation, you need to make sure to select 
"multi_obj_xml" under "Formats".  The default is just having "html" 
selected here, but that means your report will only include browsers 
that went straight to SFX, it won't include any Umlaut requests.  
Selecting both "html" and "multi_obj_request" will give you both.

== clickthrough statistics no longer valid == 

Extensive use of the SFX API completely messes up SFX "clickthrough" reports.  Every single API 
request is recorded by SFX as both a "request" and a simultaneous 
"clickthrough" for every single target included in the menu generated.   

This is not unique to Umlaut, it's true of any SFX API use.  This means 
that if you are looking at format:multi_obj_xml in your report, 
clickthroughs are entirely unreliable, there is no easy way to get 
anything useful out of them.  And if you're using Umlaut, then all (or 
nearly all) of your SFX use is multi_obj_xml, so you don't have reliable 
clickthrough stats.

The "request" stats, as opposed to "clickthrough" stats are, as far as I 
know, still reliable.  

I have reported the bug with SFX API use and clickthrough statistics to 
Ex Libris, but they didn't seem very concerned about it. If we're 
lucky, it won't be a problem in SFX 4.0.
