mgmt module is like control plane (not data plane like ltm, asm. gtm/dns modules).
it handles config storing, ha config sync and other typical control plane roles.
it doesnt do packet forwarding or storing ltm session tables.

you can monitor mgmt memory usage using free of OTHER entry in statistics minus non TMM from resource provisioning.
bigip doesnt automatically increase mgmt memory size so youll need to monitor it.

mgmt large is just extra 500MB according to https://my.f5.com/manage/s/article/K26427018
so it's considered small for today hardware ram size

hi zamroni777 thank you so much for your kind advice! As shown on the screenshot about module memory statistics ? Is TMM memory shared by LTM, GTM... besides the amount allocated to each module under "Resource Provisioning"? Please  advise, thanks in advance!

    gtm is not within tmm.
    you can view it in Resource provisioning page.
