I have 3 scheduled daily jobs that takes 3000 CPU seconds previously but in past two days, CPU usage shoots up to around 7000 CPU seconds which used up my CPU.

I was trying to investigate but find myself unable to because logs for the first and second jobs are empty though they obviously ran and consumed majority of the CPU usage (log for the third job is available and showing it takes 30 seconds to finish so CPU second should be even less than that).

Could you take a look what happened to the logs? I will need the logs to debug the jobs but they are empty now.

Could anyone shed some light on this? I thought it may be an issue others may encounter, too so I posted here.

If otherwise, I'd be happy to send along to your support email. Thanks.

Hi there -- it looks like your log files were so large that they got rotated, and our links to the log files don't handle that very well.

A slightly hacky way to see the old (pre-rotation) log files -- click on the link on the "Schedule" tab, and then add ".1" to the end of the URL when you get the empty logfile. That will move you on to the previous logfile, and hopefully there you'll have your debugging output.

Thanks, Giles, that's very helpful and I am able to get my log file now. It's indeed large. I'll reduce it going forward.

Thanks again and have a great night!

Excellent, thanks for confirming! I'll put a note into our to-do list to make that more discoverable -- it's definitely not ideal that you weren't able to see those logs right away.
