Feature request: Redirect TALP output to file

[jgraciahlrs]

TALP reports are currently written to STDOUT (presumably). In many cases this adds noise and may disturb existing workflows which expect certain data in certain positions of the output.

I suggest to add an option to redirect TALP output to a file. (Personally, I like mpiP's approach to construct the filename.)

This feature is already implemented, although not yet documented. Our documentation is lagging behind lately due to lack of time.

You can see the flag executing dlb -h:

DLB is configured by setting these flags in the DLB_ARGS environment variable.
Possible options are listed below:

Option                  Current value   Possible value (type) / [choice] / {val1:val2}
--------------------------------------------------------------------------------------
...
--talp-output-file:			(path)

Or in the extended help dlb -hh:

--talp-output-file:			(path)
    Write TALP metrics to a file. If this option is not provided,
    the output is printed to stderr.
    Accepted formats: *.json, *.xml, *.csv. Any other for plain text.

Let us know if this flag covers your needs.

Cool! This seems to be exactly what I am looking for.

This does not seem to be available in v3.2, though. I guess it is on the main branch. Please confirm and I will test it.

Yes, this was not available in the last release, but it is in the main branch.
