Hi, Right now most users are still connected as SNA devices. We are slowly moving to TCP/IP.
I assume that z/VM and ESAMON will let me know after the fact that there was slow interactive response during some interval(s) of time during the day. I would like something that would be more immediate (and of course, free ;)) Thanks, Mike -----Original Message----- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Barton Robinson Sent: January 28, 2009 11:31 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Need ideas for checking current terminal response time TCPIP in z/VM has metrics that can be used to show network response time. z/VM provides transaction data. As a performance monitor that analyzes both, ESAMON will cost you less than 1% of a cpu. Could probably do what you want with just zMON at $1200/month.
