networking - Detect if network is idle in Python -


i making python based downloader. have working multiprocessing based console script of now. know how detect if network idle. is, users not using network (browsing, surfing, etc).

it should able 2 things in regard:

  1. resume downloading when network detected idle.
  2. pause downloading when detects network activity.

one way define 'idle-ness' trigger if network activity @ 1% of max bandwidth 5 minutes straight.

is there better way detect if network idle?

i recommend using psutil.network_io_counters module:

return network i/o statistics namedtuple including following attributes:

  • bytes_sent: number of bytes sent
  • bytes_recv: number of bytes received
  • packets_sent: number of packets sent
  • packets_recv: number of packets received
  • errin: total number of errors while receiving
  • errout: total number of errors while sending
  • dropin: total number of incoming packets dropped
  • dropout: total number of outgoing packets dropped (always 0 on osx , bsd)

if pernic true return same information every network interface installed on system dictionary network interface names keys , namedtuple described above values.

in [1]: import psutil in [2]: psutil.network_io_counters(pernic=true) out[2]: {'en0': iostat(bytes_sent=143391435l, bytes_recv=1541801914l,                packets_sent=827983l, packets_recv=1234558l, errin=0l, errout=0l,                dropin=0l, dropout=0),  'gif0': iostat(bytes_sent=0l, bytes_recv=0l, packets_sent=0l, packets_recv=0l,                 errin=0l, errout=0l, dropin=0l, dropout=0),  'lo0': iostat(bytes_sent=6143860l, bytes_recv=6143860l, packets_sent=55671l,                packets_recv=55671l, errin=0l, errout=0l, dropin=0l, dropout=0),  'p2p0': iostat(bytes_sent=0l, bytes_recv=0l, packets_sent=0l, packets_recv=0l,                 errin=0l, errout=0l, dropin=0l, dropout=0),  'stf0': iostat(bytes_sent=0l, bytes_recv=0l, packets_sent=0l, packets_recv=0l,                 errin=0l, errout=0l, dropin=0l, dropout=0) }

you can keep track of sent , received bytes on interface want monitor , give information if network idle or busy.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
