mhansen / csv2pprof

Converts CSV to pprof profile format.

Use when you have some data in a database or a spreadsheet you'd like to turn into a pprof profile.

Installation

go install github.com/mhansen/csv2pprof@latest

Usage

csv2pprof < input.csv > output.pprof

Generate a stack column of semicolon-separated frame names, similar to Brendan Gregg's "Folded Stacks" format, and an integer measurement column.

Example CSV input:

stack,cpu-time/milliseconds
main;foo,1000
main;foo;bar,2000
main;baz,4000

Or you can have many measurement columns. Give units after the forward-slash /:

stack,cpu-time/milliseconds,samples,instructions
main;foo,1000,10,100
main;foo;bar,2000,20,200
main;baz,4000,40,400

CSVs must have:

• a header row
• a semicolon-delimited stack column
• one or more measurement columns

See Also / Prior Art

• Brendan Gregg's Folded Stacks Format uses semicolon-separated stacks, and a space-separated measurement.
• felixge's pprofutils converts folded stack format to pprof.

The folded stack format is just a little harder to generate from databases and spreadsheets.
