Is there a way to retrieve a list of all globals that have been read/written in a given context (eg: CSP request) or time period ?

Hello,

I would like to get a list of all globals that have been read or written during a given context. In Portal, there are counters in dashboard that give the number of read/write to globals in general.

What I am looking for : 

- some handler (eg: like $ZTRAP) that will be called everytime something is read/written to a global.

- to activate a "global log mode" in Portal that will dump some information to a file (like ^ISCSOAP for SOAP requests).

I understand this is something that can considerably slow down IRIS, but it's intended to be used only for debbuging and under no load.

As last resort, I could dump all globals (using ^$GLOBAL) and count the number of nodes inside, thern compare it after doing some operation (eg: a CSP request). That might work but this is time consuming and inefficient.
