Well, it seems that fuzzer statistics have appeared for Nov 11 (not the interim days though). Did something change? In any case, I'll keep looking at the stats in the...

I also still see some empty log files, for example: https://console.cloud.google.com/storage/browser/_details/arrow-logs.clusterfuzz-external.appspot.com/None/libfuzzer_asan_arrow/2025-11-12/01:07:04:470871.log;tab=live_object?pageState=(%22StorageObjectListTable%22:(%22f%22:%22%255B%255D%22)) ``` Component revisions (build rNone): Not available.

Update: fuzz target statistics are available for Nov 15, not later days. This applies to both `libFuzzer_arrow_parquet-arrow-fuzz` and `afl_arrow_parquet-arrow-fuzz`. Attaching screenshot of latest stats.

Well, what's weird is that prior to Nov 2, there were almost no "holes" in the daily stats (of course, this is visual inspection, so I might miss one or...

That's... annoying, especially as we've been making a bunch of changes to that particular fuzz target in recent weeks.

@DavidKorczynski @oliverchang Gentle ping here. Is the absence of daily stats for a fuzz target something I should worry about? Is it indicative of the fuzzer not being run regularly?...

> At least for us, it seems to be working. [bitcoin/bitcoin#33981](https://github.com/bitcoin/bitcoin/issues/33981) was found by Oss-Fuzz, even though the target is not run every day: Hmm. Ideally I'd like some confirmation...

Wow, thanks for looking into this @jonathanmetzman :)
