Does the Log Viewer actually work for anyone?

Is it just me, or does the Log Viewer searching basically not work?

I have my log storage configured to give me about 11 days of logs, but
I can rarely actually find stuff (that I _know_ occurred within my
window) by searching - both regex- and label-based searching. We run
at about 100+QPS, so trying to catch something in action is basically
impossible.

I'm guessing the log indexing runs async to the log entries
themselves, and it's just not able to keep pace, or the indexing jobs
themselves are just failing.

Does anyone actually have any luck searching the logs in the Log
Viewer on a reasonably high rate application?

Hi Jason,

Do you mind filing an issue on the issue tracker with some details?
(e.g. app-id, example queries, etc)

If you mind making the info public, you can also send it directly to me.

Thanks,

Hey Jason,

Please do fill out an issue but this is indeed a known issue.  We don't do currently index for regex and labels so when you do a search across your records it will take quite a while and we stop and return whatever results we've found after 10 seconds.  We are looking to improve this at some point but it does mean right now you'll get inconsistent results when trying to search across a lot of logs.

Hope that makes sense!

Greg

Thanks Greg - it totally makes sense and explains why something that
is even quite recent does not appear on a "high-rate" application.

Proppy just demo'd a BigQuery-based log analysis in the App Engine
Chat - you should just go straight to that solution under the hood...

Ah, c'mon now you are giving away the ending!  ;)  We are looking into this as a possibility.  BigQuery has some awesome capabilities and paired with logs its quite effective!

Was an issue created for this? I can't seem to find it and I would like to star it. I've been searching through my logs trying to determine a few errors we're getting and all this time I thought my lack of results was my fault. Kinda glad (or maybe not so glad) that it is Google's fault...

I didn't create an issue for this because it seemed like something was
underway already.

If you create one, I'll star it.

The symptom that really annoys me is when you have an error on your dashboard, click on it and there's nothing in the logs.  Poof!  It never happened!

Even fixing that use case would be great, something is putting it on the dashboard, maybe include the time of one of the errors on the dashboard so we can drill down that way?  Time queries work well.

Do you have a link to the log analysis demo? I'd be interested in learning more about it. (My Google-Fu didn't turn up any results)

*Mind Blown*

Looks really cool. It's always nice to see how Google uses their own APIs. This will be a good resource to learn from. Thank you very much!
