As part of bug 1026970 (switching on a new feature to help us catch stray connections to external sites during our automated test runs), it was discovered that Talos performance tests attempt to make connections to incoming.telemetry.mozilla.org, eg: https://tbpl.mozilla.org/php/getParsedLog.php?id=41951942&tree=Try 04:03:56 INFO - Non-local network connections are disabled and a connection attempt to incoming.telemetry.mozilla.org (54.245.232.191) was made. This is because the telemetry URI wasn't set to the dummy value in Talos prefs, since it doesn't use prefs_general.js (see bug 1023483). Bug 996871 (landed in production 2014-06-24) has since ensured Talos runs use this dummy URI, however this has been occurring for months/years, so: 1) Were these submissions making it through the VPN to incoming.telemetry.mozilla.org? 2) Were we accepting those submissions (ie not filtered out server side)? 3) If the answer both to #1 and #2 is yes: a) How much has this skewed the data (I don't know what % of submissions we're talking about here)? b) Do we want to try and remove those submissions retrospectively (if that's possible)? Mark - I'm not sure who is best to needinfo here, if it's not you would you mind redirecting?

I think we probably do want to get rid of them, but this has potentially far-reaching implications for any aggregated data we have (mainly data used by the telemetry dashboards). I'm going to do some preliminary investigation to see if the talos pageloader addon is appearing in telemetry submissions, but if you have any suggestions on how to more easily identify these payloads, please let me know.

Vladan suggested I check the proportion of submissions with "default" as the appUpdateChannel. For 2014-05-01, there were 4072 submissions on that channel. For comparison, the number of "nightly" submissions for that day is approximately 140k (based on checking the telemetry.m.o dashboard). None of the above submissions had the talos pageloader addon listed (according to http://hg.mozilla.org/build/talos/file/f9136c4bc616/talos/pageloader/chrome.manifest the addon id is {8AF052F5-8EFE-4359-8266-E16498A82E8B}).
(In reply to Mark Reid [:mreid] from comment #2) > Vladan suggested I check the proportion of submissions with "default" as the > appUpdateChannel. Do we definitely use 'default' in automation? I guess for Nightlies running Talos we definitely don't (though they'll 0.1% of the total). Do you record the IP of the machine making the submission, or is that discarded for privacy reasons?

I can check on new incoming data briefly, but if the problem has been fixed on Talos, that doesn't help...
Do you have any other ideas about how I could identify submissions from Talos?

(In reply to Mark Reid [:mreid] from comment #5) > Do you have any other ideas about how I could identify submissions from > Talos? Joel, do you have any ideas here? Would checking for the presence of talos pageloader addon be sufficient to find all potential accidental talos submissions to telemetry? We can't use IP, since it is discarded.

pageloader doesn't account for all our talos tests (most of them), could we detect certain preferences? maybe hardware specifics?
Flags: needinfo?(jmaher)
We can try fingerprinting Talos machines based on their hardware. Joel, can you attach the contents of the about:telemetry page from a Talos machine. The data from the "System Information" subsection ought to be enough.

Vladan, here is a list of the hardware we use for talos: https://wiki.mozilla.org/Buildbot/Talos/Misc#Hardware_Profile_of_machines_used_in_automation In order to get to about:telemetry, I will need to get loaners (which I need one for another purpose). If you need me to get one of each type, please let me know.

ok, this will take a week or two, but I will get it.

Roberto, can you check for the proprotion of Telemetry reports with the sysinfo characteristics? You can use a combination of locale + cpucount + memsize + OS + the various hasflags + profileHDDModel + adapterVendorID + adapterDeviceID + adapterRam. Unfortunately for Mac, this is going to catch a lot of Telemetry submissions from real users, since there's less variation in Mac h/w configurations.

OK, I will check it.

Looking at the submissions of nightly between 14/06 and 18/06 I see only 15 out of 1049600 submissions matching the following criteria (windows 7 box): "OS": "WINNT", "memsize": 3063, "arch": "x86", "version": "6.1", "binHDDModel": "WDC WD5003ABYX-01WER", "adapterVendorID": "0x10de", "adapterDeviceID": "0x104a", "adapterRAM": "1023" Doesn’t seem like there is anything interesting here.

Using only the prefix of binHDDModel (i.e. "WDC WD5003ABYX") to match pings doesn't change the result.
