It would be amazing if we could get back how much memory our tools use in FireCloud.
Because a lot of what is run on FC is too big or cumbersome to run locally, pre-FC memory profiling can be hit or miss, and rolling our own custom solutions into our Docker images is less than ideal.
Being able to quickly see memory usage, especially in large-scale runs, could vastly assist in being able to come up with prediction formulae that we could incorporate into the memory requests in our WDLs, and potentially save a lot of money lost due to requesting too much memory/core.
Such a thing should be relatively straightforward to implement, as cromwell has a monitoring_script workflow option with just such usages in mind.
