cat > /tmp/nkthreads.c

Paste in the following:

#include
#include
#include
#include

int main()
{
struct pst_dynamic dyn;
int error;

if ( pstat_getdynamic( &dyn, sizeof(dyn), 1, 0) == 1 )
{
printf("Thread usage: %d of %d\n", dyn.psd_numkthreadsallocd,
dyn.psd_maxkthreads);
printf("Proc usage: %d of %d\n", dyn.psd_numprocsallocd,
dyn.psd_maxprocs);
}
else
perror("pstat_getdynamic:");
}

Press followed by Ctrl D to close the file.

# cc /tmp/nkthreads.c -o /tmp/nkthreads # Compile and name executable

I have the same problem as Jannik, since I am running on a B.11.11,

cpp: "/tmp/nkthreads.c", line 1: error 4034: Bad syntax for #include directive.
cpp: "/tmp/nkthreads.c", line 2: error 4034: Bad syntax for #include directive.
cpp: "/tmp/nkthreads.c", line 3: error 4034: Bad syntax for #include directive.
cpp: "/tmp/nkthreads.c", line 4: error 4034: Bad syntax for #include directive.

Any possible help?

Thanks in advance.

drop alex a mail... I were able to compile it on another host. This should run for you as well.
Copy the file to say /tmp and do a chmod 755 /tmp/nkthreads and the run it.

Re: nkthread

Jannik — Wed, 14 Sep 2005 03:10:21 GMT

and the file is :-)
cc /tmp/nkthreads.c -o /tmp/nkthreads

or drop me a mail and i will send the compiled file: jto@telia.dk

Hi
When I run the program it shows
/nkthreads
Thread usage: 1128 of 4000
Proc usage: 638 of 4000

When I run the kmtune to check the value
kmtune |grep thread
max_thread_proc 256 - 256
nkthread 2048 - 2048

Is it correct
