Memory and CPU used

[Fred vS]

Hello everybody.
I want to know the amount of memory and cpu used by the application.
Is there a way to retrieve that with FPC for Windows, Linux and OSX ?
If not, witch external program could i use to get that (for Windows, for Linux and for OSX) ?
Many thanks.

In Linux, we have various Task Monitors, System Monitors and utilities like HTop or PowerTop.
You can see there number of CPU wakeups from idle state.
You can see there amount of allocated memory and CPU usage of each process.
Those tools are part of distribution or they are in repository.

Hello Mr Blaazen and thanks for your answer.
The idea was to load in the Lazarus application a external console application and use  AStringList.LoadFromStream(AProcess.Output) method to retrieve the output of the command line prog.

Now witch command line could give me the amount of memory and cpu used by my Lazarus application ? (for Windows, Linux and OS X)

Thanks

I don't know exactly.
You can list processes in Linux using 'ps':

Code: [Select]

ps -AYou can select output using:

Code: [Select]

ps -A | grep firefoxThis command has really many options for output and formating, so type:

Code: [Select]

man psand look in the manual pages.

Hello Mr Blaazen.
Sorry, but what a jungle that ps command.
For example :

Code: [Select]

ps -A | grep miximum
give me :

Code: [Select]

1856 ?        00:05:26 miximum
Ooops, what does that mean ?

And with  man ps, i do not have find how to retrieve the memory usage and the cpu usage...

But, you have understood what i want, step by step we gonna find the solution 

PS: By the way, if it exists a FPC command for that, i m challenger...
