Up: HL7_Event_Monitor 

Email of 20-Sep-2019 by David Whitten to Hardhats

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,$$CJ^XLFSTR("Official VistA HL7 Event Monitor Code",IOM),!,$$
 ;;
 ;;The "monitors" that are officially included in the VistA HL7 package are
 ;;listed below.

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.
