Real time monitor for z/OS TCPIP interface statistics

Interface 1 Minute

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   ,,...
TAP0            ,09:11:12,     0,     0,      ,      ,,     0,     0,,...  
TAP0            ,09:11:22,     0,     0,     0,     0,,     0,     0,,   
TAP0            ,09:11:32,     0,     0,     0,     0,,     0,     0,,  
TAP0            ,09:11:42,   348,   348,    34,    34,,     3,     3,,   
TAP0            ,09:11:52,     0,     0,     0,     0,,     0,     0,,  
TAP0            ,09:12:02,     0,     0,     0,     0,,     0,     0,, 
TAP0            ,09:12:12,     0,     0,     0,     0,,     0,     0,,  
TAP0            ,09:12:22,     0,     0,     0,     0,,     0,     0,,  
TAP0            ,09:12:32,     0,     0,     0,     0,,     0,     0,,  
TAP0            ,09:12:42,     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.

I retired from IBM where I worked on MQ on z/OS, and did customer stuff. I retired, and keep my hand in with MQ, by playing with it! I'm now an #IBMChampion from my work trying to make z/OS product more usable.
