Hi all,

I'm new to VM/370 and wonder how the output of the CP MONITOR command, which is spooled to MAINT's reader, can be accessed.
I found no way to READ, RECEIVE or SFBROWSE these specific files, getting error messages like "READER EMPTY OR NOT READY"?
or? "SPOOL FILE xx DOES NOT EXIST OR HIS HELD" but "Q RDR" shows these files and they are definitely not in HOLD state.
In z/VM seem to exist utilities like MONWRITE and? MONSCAN but how can this output be browsed? in VM/370??

Thanks for any hint

Cheers Ralf?

Hi Ralf,

These can be read by various utilities that use DIAGNOSE X'14' to read spool
files. One I came across somewhere is called RRMONDSK. This was designed for
VM/SP I think but needed only a small tweak to make it work on VM/370. It was
probably on the Waterloo mods tape or one of the VM Workshop tools tapes.

Hi Peter,

Thank you very much for your reply, which confirms my assumption that it cannot be done
without additional utilities. I'm just wondering why IBM made it so convenient to collect the data
but so complicated to analyze it.?

Hi Peter,

it took me some time, but eventually I found the MONSTATS program from the 1985 Waterloo Tape at this website:
