Does anyone know about the ^XTMP global and the series of nodes apparently created by HL7 ?
ie: there are nodes in the ^XTMP() global with a first subscript of either: "HLEV CHK773AC "_<Timson Date+Time> or
"HLEV STUB "_<Timson Date+Time>
Apparently "HLEV" means Health Level Seven Event Monitoring.
The nodes seem to get SET in the HLEVX* routines. The dates on these routines are in February 2004 or so.
Notably the HLEV CHK773AC nodes are set in the routine ^HLEVX002
Soon after we copy our Production environment to make a test or training or development environment, there is something
that runs and fills up a LOT of journal files. This seems to be run as a background task since the Journal files have a
process id that has %ZTMS1 running if it finishes before we notice.
The sub-routine LIST^HLEVX lists these "monitors"
LIST N I,T W @IOF,$$CJ^XLFSTR("Official VistA HL7 Event Monitor Code",IOM),!,$$

So this apparently these tools let us track possible problems with HL7 messaging.
The question I have to ask is why they seem to explode our journal space when
we first start up the non-production environment.
The burning question is, should we turn this monitor off or leave it on ?
Does it matter only in production environments or does it matter in non-production?
Does any know if we should be checking these reports regularly ?
Are problems with HL7 that these monitors find either common or uncommon ?
Thanks for your input.
