My rust application's memory keep increasing over a time. Every 20 minutes, I can see steady rise of 200mb.
What are the tools I can use to profile rust server?
The classic tool is massif:
valgrind --tool=massif ./target/release/foobar
There's also this that came up on a search just now which looks fancy.

I tried valgrind. It seems like program has to exit to show the profile. Ctrl + C is not giving the data.
I'm looking for something where it'll give me sample for a certain period of time.
My program is a tokio server
Valgrind has an option to run via gdb without exiting the program.
valgrind --tool=memcheck --vgdb=yes --vgdb-error=0 ./prog
gdb prog
then in gdb:
(gdb) target remote | vgdb
and then continue and pause execution of the program in gdb, and call in gdb:
monitor leak_check full possibleleak increased
