Is there some kind of indicator in Eclipse which displays the amount of
RAM used by Eclipse?
I found two plugins that do this (by example Freemem,
http://junginger.biz/eclipse/), but today i read something about the
org.eclipse.core/perf/showHeapStatus option so i started wondering if
something like that was already included in Eclipse?

Thx!
Greetz,
Jeroen

Those kinds of tools are only going to show how much heap is being used,
not the total system RAM in use. You can control Eclipse's heap usage by
specifying -Xmx and -Xms options on the eclipse.exe command-line. You
can monitor total system RAM usage through whatever tools you OS
provides. Remember that any Java process' total RAM usage is not only
the heap size but also all the other artifacts that are loaded into the
VM, including classes.

HTH,
Eric

I am aware of these options and the fact that it only shows the used
heap. It's just a fancy 'nice to have'. Other applications like IntelliJ
and jEdit also have it.
While searching some more i found a nice one from the Eclipse project
itself:
http://dev.eclipse.org/viewcvs/index.cgi/platform-ui-home/de v.html?rev=1.38
(update site:
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/plat form-ui-home/updates)

Thx!

Using Eclipse 3.1 M7, create a file called ".options" in the Eclipse
install directory, containing the following line:

org.eclipse.ui/perf/showHeapStatus=true

Start Eclipse with the -debug command line argument, and you will now
see heap usage in the status line, along with a button to force garbage
collection. Clicking on the heap will "snapshot" the current heap
usage, which is useful for finding leaks and observing memory growth for
a given operation.

Ah that's indeed a cool memory indicator :) It seems to be allmost the
same as the one found at
http://dev.eclipse.org/viewcvs/index.cgi/platform-ui-home/de v.html?rev=1.38
(but with some more options for debugging)

thx!
Jeroen
