11MB dat file wont upload

11MB dat file wont upload


I have a large dat file that was taken over a period of hours.  When I try to upload it takes the file and then doesnt say anything on the page.  Looking at the javascript console there is an error message about the file size being too large.

  • Is there an offline analysis tool?  Can we use VTune to analyze the snapshot?
  • What is the file size limit for uploading and analyzing?
  • Is it possible to break the dat file up?  Is there some other reader i can use to analyze or manipulate the file so that we can analyze it?

Here is the error message:


Uncaught DOMException: Failed to execute 'setItem' on 'Storage': Setting the value of 'gatheredData' exceeded the quota.

Hi Justin,

The current implementation of the viewer has a limit of ~5MB of data. As a workaround, consider splitting the data file into multiple smaller files:

  • Make sure to preserve the header information in all files - this is the content from the beginning of the file up to and including the dstat header information in lines 29-30 ("epoch","usr","sys"....)
  • Split the content of the dstat performance data (beginning in line 31)

You can then load each file separately into the viewer and look at the results.

Hope this help.
