How do I monitor or view the thread count of a certain process on AIX?
ps -o thcount -p <process id>
That would give you only the thread count.
Play with other field specifiers for the "-o" option (see 'man ps') for other info. For instance
ps -o pid,comm,user,thcount -p <process id>
Another option is to use this to see all the processes and their threads for a single user. Replace
USER_ID with the user's ID. Don't replace
THREAD with anything, use that literal string:
ps -flu USER_ID -o THREAD -m
