Hi George, Adding to Kevin's comment -- we have found the ability to extract Darshan parser output in JSON format to be valuable in a couple of other external projects too, but it is not currently on any development roadmap for integration into Darshan proper. It is something we can consider in the future though, especially since we are working on other features that will probably make this easier (namely, implementing a Python interface to the darshan-utils library). If it's useful in the meantime, I can point you at code from one of our projects (TOKIO) that implements a JSON parser for Darshan logs. TOKIO is a broader project concerned with holistic I/O analysis of HPC systems, and as part of it we have implemented a number of different Python tools for analyzing different I/O logs (including Darshan), all in the pytokio repo: https://github.com/NERSC/pytokio. 'bin/cache_darshan.py' is the script that can take a Darshan log file and spit out JSON data for all of the counters, metadata, etc. Thanks, --Shane On 08/21/2018 06:16 PM, George Papadimitriou wrote:
Hi Kevin,
This is what we are�currently doing. But I've found that parsing the ascii output can be a bit tedious and not an elegant solution to the problem.

� I don't think we have a plan for it right now. I think the easiest method would be to take the ASCII output and convert it to JSON using a separate tool.

Hello,
I'm aware of an open ticket (https://xgitlab.cels.anl.gov/darshan/darshan/issues/242) about having an option in darshan-parser to enable json output.
Is this feature on darshan-parser's roadmap ?
Thanks,
George
