Perhaps we could compare dumps of various monitor.exes. The command procedure actually opens up three more classes: VMS1, VMS2, and VMS3; their output follows for interested readers; but unfortunately on my system no items seem to be reserved :) VAX/VMS Monitor Utility VMS DEVELOPMENT 1 on node RULLFS 15-JAN-2013 21:13:53 CUR AVE MIN MAX FCP Call Rate 0.00 0.00 0.00 0.00 Volume Lock Req.

That command procedure's comments say that it only works on specific releases of VAX/VMS, namely 5.0, 5.1, 5.2, 5.4-2, 5.5, 6.0, and 6.1. Does anyone know if it works on (say) 7.3 as well? I'm guessing no, due to the nature of the version-specific changes. -Dave On 01/14/2013 01:54 PM, Erik Olofsen wrote: And the result: VAX/VMS Monitor Utility ETHERNET STATISTICS on node RULLFS 14-JAN-2013 19:54:12 CUR AVE MIN MAX Packets/second 20.59 28.87 12.95 85.04 Kbytes/second 2.65 3.66 1.99 8.63 Packet size 121.00 140.10 102.00 169.00 Multicast Packets/second 4.31 5.61 3.65 8.27 Multicast Kbytes/second 0.33 0.66 0.32 1.32 Multicast Packet size 108.00 119.80 90.00 196.00 Trans Single Collision 0.00 0.00 0.00 0.00 Trans Multiple Collision 0.00 0.00 0.00 0.00 Trans Initially Deferred 0.00 0.00 0.00 0.00 Internal Buffer Error 0.00 0.00 0.00 0.00 Local Buffer Error 0.00 0.00 0.00 0.00 Buffer Unavailable 0.00 0.00 0.00 0.00 On Mon, Jan 14, 2013 at 07:29:01PM +0100, Erik Olofsen wrote: With Google I found: https://mail.encompasserve.org/anon/htnotes/note?f1=VMS&f2=2314.0 Erik On Mon, Jan 14, 2013 at 05:54:54PM +0000, lee.gleason at comcast.net wrote: I get: $ patch monitor.exe PATCH Version 5-05 20-June-1991 %PATCH-I-NOLCL, image does not contain local symbols %PATCH-I-NOGBL, some or all global symbols not accessible PATCH>exam 4158+33e 00004496: 00000000 Erik The addresses of the structures changed for each version or so of VMS...you'd need to locate them with the fiche, or reading a dump of the image, or , for older versions of VMS, just using the Google to find one for your version. I enclosed that one just as an example of what gets patched. Lessee....I also recall that MON ETHERNET required PHY_IO privilege, and needed a logical name NI$DEVICE set to be your network adapter's name to work. -- Lee K.
