Thank you.
Is this out of line?
Default interval . . . . . . . .   15.00
This is the default value. It should be OK.
Collection library . . . . . . .   QPFRDATA
Default collection profile . . .   *STANDARDP
It collects basic parameters, including network usage. It should be OK.
Cycle time . . . . . . . . . . .   000000
Every new *MGTCOL starts at midnight. Fine.
Cycle interval . . . . . . . . .   24
One new *MGTCOL is created every 24 hours. Fine.
*MGTCOL retention period:
   Number of units  . . . . . . .   00168
   Unit of time . . . . . . . . .   *HOURS
*MGTCOL objects are deleted from the system 168 hours (7 days) after 
their usage for collecting data.
Note that *MGTCOL must be dumped to database file to be analyzed (with 
CRTPFRDTA command or with "Create standard database files" set to *YES 
during collection). I am not aware of any interface to access *MGTCOL 
content.
You could, may be, reduce the retention to 2 or 3 days, as they are 
dumped to database members.
Enable system monitoring . . . .   *YES
Create standard database files     *YES
As far as members...

Database members can be removed according to STDDTARET parameter of 
CFGPFRCOL. And, If I remember fine, PM/400 processes can also remove 
those members depending on CFGPM400 or GO PM400 settings.
Therefore, in my opinion, the size of *MGTCOL is due to your workload.
All the *MGTCOL below look to have the same size per day, around 4,5 GB.
You have 3 collections for 01th of November probably because of some 
restricted state (or collecting jobs ended) between 01:00 and 23:00, but 
the total is quite 4,5 GB.
The size of the collection of 05th of November is lower than the other 
because of the RTVDSKINF snapshot at 04:00.

If the size of QPFRDATA is a concern, you could keep less *MGTCOL. 
Usually we keep only two of them, but we make sure to have 40 days of 
database members so that we cover one month and more.
