Server side memory capture issue

[abhishek]

Doing remote java profiling on the server from local machine. While capturing memory snap in server side profiling its taking too long to capture.And its saving on the server itself,is there any setting to save memory snap shot on the local machine as i am worried of space issue on the server.

No. Memory snapshots are always captured at the same machine as the profiled application.
When you profile a remote application, the profiler UI offers to automatically transfer a copy of the captured snapshot to the local machine.

Hi Anton,

Upon analysis i found that memory snapshot having size 1gb and more which are giving error message "not a valid snapshot file" don't have index file corresponding to them.As,it can be seen in the memory snapshot which are opening without any issue.Could you site me the reason why the index files are missing?

Thanks in advance,
Abhishek

Hello Abhishek

issue 1-Getting error message upon opening memory snap shot -"not a valid snapshot file".
Step done-
1-capture screen shot in yourkit java profiler format set
2-capture and transfer(compressed)

Could you please provide an example of such snapshot. Please zip it and share with DropBox or a similar service. You can send the download link to [email protected]

Without the snapshot we can't tell what the problem is.

issue 2-Losing focus on yourkit while running a test .

I'm afraid I don't understand what you mean. Could you please describe the problem in more detail.

You should not worry about index files. Their only purpose is to speed up snapshot loading if you open it more than once. Obviously, if snapshot did not open (was reported invalid) no index file is created for it.

We do not the reason why the spanshot is truccated. For example, there is not enough space to save full snapshot file. May be snapshot was trancated during transfer from server machine to the machine where you analyse it.

If you always get such truncated snapshot, please send us all logs from ~/.yjp/ directory.
