threads

11.0 N-class
two parts.
our system is running an application that uses many multi-threaded processes.

a) How can I get a thread count for the system?

b) is there an easy way to see how many threads each process is using?

TIA

Do you have glance/measureware installed? If not, you can install a trial version, and then determine if that's what you need, then you can purchase it.

I've already tried the glance option. This server must have already used the trial version because when I load it and run it, it tells me the trial period has expired.

I was hoping there was another way besides glance.

Try to use this little trick to start your expired glance :

touch -t 200008080101 /var/adm/.ao
/opt/perf/bin/gpm &

It works at least with version C.02.40.00.

Hi,

If you have configured q4 you can use this scripts to know the number of threads:

a)Process:
#!/usr/bin/sh
cp /stand/vmunix /tmp/vmunixq4
/usr/contrib/bin/q4pxdb /tmp/vmunixq4 2> /dev/null
/usr/contrib/bin/q4 /tmp/vmunixq4 /dev/mem <<-EOF
load struct proc from proc max nproc
keep p_pid==$1
print p_comm p_pid %d p_livethreads %d p_suspended_threads %d p_cached_threads_count %d
EOF

b)System:

#!/usr/bin/sh
cp /stand/vmunix /tmp/vmunixq4
/usr/contrib/bin/q4pxdb /tmp/vmunixq4
/usr/contrib/bin/q4 /tmp/vmunixq4 /dev/mem <<-EOF
load struct kthread from kthread max nkthread
keep kt_stat != 0
EOF

Best regards.
