flamegraphs for java with -e alloc and --interval don't download (Checksum does not match) error #27

Closed jlynch1 closed 8 months ago

jlynch1 commented 8 months ago

When I run with java async-profiler cpu events - all the flamegraphs are downloaded

--tool async-profiler -e cpu -l java -o flamegraph -t 2m --interval 60s

but with java async-profiler alloc events I get an error saying Checksum does not match

--tool async-profiler -e alloc -l java -o flamegraph -t 2m --interval 60s

Default profiling tool async-profiler will be used ... ✔

Checksum does not match, retrying: /tmp/agent-flamegraph-1382909.html.gz...
Checksum does not match, retrying: /tmp/agent-flamegraph-1382909.html.gz...

with alloc events, when I remove --interval 60s a single flamegraph is produced and downloaded.

looks like a timing issue, I tried changing (perfDelayBetweenJobs) but it doesnt seem to introduce a delay at all as there is no delay between the jobs timestamps. I see the sleep in the code in ./internal/agent/profiler/jvm/async_profiler.go

maybe if the filename had a timestamp or an interval counter rather than the same file filename agent-flamegraph-1382909.html for each interval, it would help. Also the perfRecordOutputFileName and perfScriptOutputFileName ?

josepdcs commented 8 months ago

Hi @jlynch1,

Checksum error can be experienced when some problem occurs downloading/copying the result file from the remote node. Maybe caused by an unexpected network problem.

I've unable to reproduce this case. I've been able to download all flamegraphs for any event type: alloc, cpu, itmer...

By the way, checksum is not related with manner of naming the result file.

killbulle commented 8 months ago

fyi experiment this also randomly on an aws cluster , independently of option , will dig more btw thks for this awesome tools !

jlynch1 commented 8 months ago

it happens for me every time I attempt to use alloc event with an interval

in retrieveFileOrRetry() I uncommented the debug line and added in filesize

So I see a few problems

josepdcs commented 8 months ago

I'll check it again. Seems you're right

jlynch1 commented 8 months ago

The only way I can see it worked for you, is if you downloaded the files with a single call to the loop with tail command in retrieveFileOrRetry().

Also the files do get overwritten - due to having the same name each time, so if they are been downloaded slower in chunks, a new file (same name, with different data and different checksum) overwrites the previous one, and the tail command is downloading from this new file - so the contents of the file downloaded will never match up and neither will checksum == remoteFile.Checksum

josepdcs commented 8 months ago

There was a problem calculating the offset of the remaining file to download when it couldn't be downloaded all at once. I've published a new release 1.2.1 which fix this one.

jlynch1 commented 8 months ago

I have pulled the latest changes but I still have the same underlying issue as described in the ticket. which is caused by having the same filenames e.g. /tmp/agent-flamegraph-3328373.html for each interval and the files get overwritten with the output for the next interval.

Notice the download for the first file failing and the 3 retries for the first file have the same file size and checksum for the 2nd file 47460 bytes and checksum "7ec5eb445db99e1abe5352b48d6e3806" because the first output was overwritten by the 2nd output with filename /tmp/agent-flamegraph-3328373.html.

Ok. The problem is with the continuous mode. I got it. The file should be renamed according the iteration.

josepdcs commented 8 months ago

Hi, @jlynch1. Now, for continuous mode the result file is renamed after each iteration. It should resolve the issue experienced by you. Release: https://github.com/josepdcs/kubectl-prof/releases/tag/1.2.2

Hi @josepdcs, I can confirm it is now downloading correctly the flamegraphs for me in normal and continuous mode. Thanks for all your work in maintaining this project.
