ark::logging::tools::TransferProgressMetrics

Defined in header “ark/logging/tools/progress_output.hh”.

A helper class that allows you to emit progress of a download/upload in a pretty fashion.

void print(const char * transfer_type, bool final_output)
Prints out the metrics to stdout. Pass in a string indicating if we are uploading or downloading.

std::chrono::steady_clock::time_point start_time= std::chrono::steady_clock::now()
Time the download started.
std::chrono::steady_clock::time_point rate_window_start_time= std::chrono::steady_clock::now()
Time the last rate window was calculated (at roughly 1Hz).
uint64_t bytes_transferred_at_rate_start= 0
Bytes transferred when the last window began.
double rate_mbs= -1.0
Last rate, in MB/s.
std::atomic< uint64_t > bytes_transferred= 0
Total bytes transferred so far.
std::atomic< uint64_t > splits_transferred= 0
Total splits transferred so far.
uint64_t splits_needed= 0
Total number of files expected.
uint64_t manifests_needed= 1
Total number of manifest files expected.
