I want to monitor simple search application which caches some data during
search process, and from time to time remove some of the data from cache.

Search process can take several minutes, and therefore I would like to
know what was maximal size of alive (not collected by garbage collector)
cached data during the execution process. How can I do it with TPTP ?

Another thing in Memory Statistics View. When I have size of all alive
instances of -- let's say -- Cache class, does it refers also to sizes of
all o objects referenced from instances of Cache class (via fields) ? If
no, how can I obtain such an information with TPTP ?

Thank you,

Maciej

Hi Maciej,

TPTP currently does not support max size of alive object monitoring. Please
feel free to submit an enhancement request with your use case to be
considered in the next enhancement cycle.
The size in the view shows only size of the listed class, it does not
included the referenced instances. Use the 'Trace object allocation sites'
option under 'Memory Analysis'. (select Edit Options in wizard UI) allows
you to link the references and inspect the detail about the references.
