lib_net_stats module

Routines for network statistics.

lib_net_stats.compute_txrx_bytes(stats_values_init, stats_values_end, v=0, file_log=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>)

Computing total traffic for ogging of network statistics.

stats_values_init : list

start times.

stats_values_end : list

end times.

v

verbose if 1 [unused]

file_log

handler for log file [unused].

delta_stats

stats_values_end - stats_values_start

lib_net_stats.get_network_stats(nodes_list, over_slurm=0, v=0, file_log=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>)

Obtain network statistics from nodes.

nodes_list : list of str

nodes names.

over_slurm : int

used to select network interface.

v : int

verbose if 1.

file_log : file handler

handler to log file.

stats_params

list of paramters for each node.

stats_values

list of lists with values associted to stats_params.

ping_times

lists of lists with ping results among all pairs of nodes.

TO DO:

Change over_slurm for explicit selection of the interface.

lib_net_stats.init_net_stats()

Initializate structures for network statistics.

lib_net_stats.print_network_stats(nodes_list, stats_params, stats_values=[], stats_ping=[], title_stats='', v=0, file_log=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>)

Write output for logging of network statistics.

nodes_list stats_params

list of paramters for each node.

stats_values

list of lists with values associted to stats_params.

stats_ping

lists of lists with ping results among all pairs of nodes.

title_stats

str to be used in suffix of the title of the statistics.

v

verbose if 1.

file_log

handler to log file.

lib_net_stats.print_network_totals(nodes_list, v_str_hadoop, v_stats_param, v_stats_values_s, v_stats_values_e, v_stats_ping, v=0, file_log=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>)

Print network stats.

It calls print_network_stats() all tuples from the input.
