Operating System on User Agent

[IvanRF]

I started testing the stable version (v1.1.2) but I think this issue is still present on 2.0.

When sending a post to GA the userAgent in my case is:

java/1.8.0_112-b15/Oracle Corporation/Java HotSpot(TM) 64-Bit Server VM/Windows 10/10.0/amd64

It includes the OS data but I guess the format is not correct or at least is not the one that GA expects.

User Agent Override

Example value: Opera/9.80 (Windows NT 6.0) Presto/2.12.388 Version/12.14
Example usage: ua=Opera%2F9.80%20%28Windows%20NT%206.0%29%20Presto%2F2.12.388%20Version%2F12.14

The first part is correctly gathered by GA:
Browser: java
Browser Version: 1.8.0_112-b15

but then the rest is empty:
Operating System: (not set)

I just made a test overriding the user agent:

defaultRequest.userAgent("Java/1.8.0_112-b15 (Windows NT 10.0; Win64; x64)");

Now I have to wait until GA audience reports are available, but I will share if that format works.

thank you. Please check if that new format works and we can make that as default. Btw, are you using version2? Version 1 is not going to be updated going forward.

[IvanRF]

I can confirm it works:
Operating System: Windows
Operating System Version: 10

To test it faster I used the version on Central Repository. Do you plan to upload v2.0?

[IvanRF]

In order to dynamically build the user agent string, I'm testing this code now:

OperatingSystemMXBean os = ManagementFactory.getOperatingSystemMXBean();
defaultRequest.userAgent("Java/" + System.getProperty("java.version") + " (" + os.getName() + "; " + os.getArch()+ ")");

which in my case sets Java/1.8.0_112 (Windows 10; amd64), not equal but similar 😃

[brsanthu]

I will try to upload v2 with beta label over the weekend.

Excelent! another question: why screenResolution is not set by default?
I'm currently using config.setRequestParameterDiscoverer(new AwtRequestParameterDiscoverer()); but the JavaScript library for GA always send that info and the screenColors.

By the way, comparing with the Google's library, screenColors sends '32, 32' but it should be '32-bit'. screenResolution sends '1366x768, 96 dpi' and should be '1366x768' (although dpi info could be useful).
Screen Resolution
Screen Colors

Since many times, the env where this library is used may not have access to display to get the stats and that's why it is not set by default.

I will look into the screen resolution and colors info.

[IvanRF]

oh, you're right, I was thinking only on desktop apps but the library could be used on a server.

[IvanRF]

Finally, the second report is available. The OS value didn't worked.
I sent Windows 10 and apparently they expect Windows NT 10.0 (since that value worked).

So, a simple logic could be applied there to replace Java property value to a valid value.

[IvanRF]

Yes, that change worked (I don't know if there is any correlation but when the OS is valid the pageview appears faster on the audience report).

I applied this simple logic, but more work is needed to support other OS:

OperatingSystemMXBean os = ManagementFactory.getOperatingSystemMXBean();
String osVersion = (isWindows()) ? "Windows NT " + os.getVersion() : os.getName();
config.setUserAgent("Java/" + System.getProperty("java.version") + " (" + osVersion + "; " + os.getArch()+ ")");

Any news on this? I'm experiencing the same issue, will experiment with your previous suggestions!

[nicolabeghin]

Using like this at the moment:

public class WMRequestParameterDiscoverer extends AwtRequestParameterDiscoverer {
    protected String getUserAgentString() {
        return String.format("Java/%s (%s %s; %s)", System.getProperty("java.version"), System.getProperty("os.name"), System.getProperty("os.version"), System.getProperty("os.arch"));
    }
}

Yes ran into the same issue, took me quite a while to find out why my requests are not working.
