Real time monitor for TCPIP Interfaces

  • 1.  Real time monitor for TCPIP Interfaces

    Posted Mon March 11, 2024 08:02 AM

    Ive put up on Github a program which provides real time statistics for z/OS TCPIP interfaces.  For example

    Interface       ,HH:MM:SS,IBytes,OBytes,IB/sec,OB/sec,,IUP   ,OUP   ,, IMP, OMP, IBP, OBP, InE, OuE, InD, OuD 
TAP0            ,09:11:12,     0,     0,      ,      ,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:11:22,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:11:32,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:11:42,   348,   348,    34,    34,,     3,     3,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:11:52,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:12:02,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:12:12,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:12:22,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:12:32,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0, 
TAP0            ,09:12:42,     0,     0,     0,     0,,     0,     0,,   0,   0,   0,   0,   0,   0,   0,   0,

    Where the values are deltas from the previous time interval

    IBytes is input bytes during that interval

    OBytes is output bytes

    IB/Sec is rate of input bytes

    OB/Sec is rate of output byte

    IUP is count of Input Unicast packets

    OUP is count of Output Unicast packets.

    You get one output file per interface.

    The output file can be downloaded and used as input to a spread sheet, to graphically display the data.

    I'm working on some code to display the global TCPIP stats, but I do not think they are very interesting.  If they are interesting to you, please let me know and I'll add my code.
