Closed Bug 1189164 Opened 6 years ago Closed 6 years ago
Quick follow up to test that monotonic clock fix solves negative time for last subsession
Perhaps write a heka filter to check to see if these negative values are found as soon as the fix hits nightly. Also good to re-run bcolloran's scripts once enough data is available: https://bugzilla.mozilla.org/show_bug.cgi?id=1186713#c1
This should be in Nightly>=20150730, we should filter for that build id.
I eyeballed this in kibana (the table shows the newer build id pings, sorted by subsessionLength): https://kibana.shared.us-west-2.prod.mozaws.net/#dashboard/temp/AU76r2croEkfX-6KQ_Co Only 3 pings with negative subsession lengths so far (not counting the "matching" saved session ping).

Should have mentioned that was over a 2 day period. Here's a 7 day period that includes 7/30: https://kibana.shared.us-west-2.prod.mozaws.net/#/dashboard/temp/AU76r2croEkfX-6KQ_Co ~15 negative subsession lengths (the earlier builds are generating a lot more). At any rate, not as good as an actual comprehensive analysis, but early indications suggest improvements.
Odd, with the current implementation i expect no negative subsessionLength fields. I wonder if the remainders are local builds who have not updated their source yet - if so this should drop down to near-zero soon (and the remainders should only affect a very small set of clients).
Note that both -60 subsessionLengths that i can see now are from the same client id. Those are both the same value, once in a shutdown and once in a saved-session ping. Given oddities on Nightly i'd wait a bit for more data before drawing conclusions from that.
I only see 4 submissions (duped as saved-session & shutdown) with that issue in the query: https://kibana.shared.us-west-2.prod.mozaws.net/#/dashboard/temp/AU76r2croEkfX-6KQ_Co That is a really low numbers and might just be people building from outdated source etc.
