This is a coding example working on IRIS 2020.1 and on Caché 2018.1.3
It will not be kept in sync with new versions
It is also NOT serviced by InterSystems Support !
Standard error logs in IRIS / Caché / Ensemble are written global ^ERRORS.
As this piece dates back some decades back to previous millennium its structure
is far from the typical SQL storage structures.
The global is written by routine ^%ETN.int and the content becomes visible from
terminal command line by routine ^%ERN or in Mgmt Portal as Application Error Log.
It is just not available to SQL as there is no Class wrapped around.
For several reasons:
- When it was designed it was good practice to have index like structures in the
same globals as the data. If I say 'like', this means it is of no use for SQL. - As next the content of objects are going to deeper levels than the rest. As a
consequence, the depth of subscripts (typically IdKey) varies from 3 to 11.
^ERRORS is independent in every namespace
It is structured by Day,SequenceByDay, Type, ItemName (Variable, OREF),Value
zrcc.ERRORStack covers this as SQL table.
Deeper content of the objects becomes visible by the included custom query.
The SQL procedure zrcc.ERRORStack_Dump(Day,Sequence) returns all available
content and presents subscripts and values as you see in global listing.
How to make best use of both components: first: find your day and sequence number using SQL
Example: SELECT * FROM zrcc.ERRORStack where item='$ZE'
Day Seq Stk Type Item Value
2020-07-02 1 0 V $ZE <WRITE>zSend+204^%Net.HttpRequest.1
2020-07-07 1 0 V $ZE <WRITE>zSend+204^%Net.HttpRequest.1
2020-07-15 1 0 V $ZE <WRITE>zSend+204^%Net.HttpRequest.1
2020-07-20 1 0 V $ZE <LOG ENTRY>
2020-07-26 1 0 V $ZE <WRITE>zSend+204^%Net.HttpRequest.
Then in SQL : CALL zrcc.ERRORStack_Dump('2020-07-26',1)
