Using HP-UX v11
Need to monitor cpu and memory usage, total for system and separately for each user in command-line mode.
Found out next ways to monitor total cpu usage under hp-ux:
1) vmstat, also shows free memory
2) sar -M
ps -eo user,pcpu - does not work, means 'user-defined format'... (4 Replies)
I am trying to write a small (and rather simple) script to gather some info about the system and piping it to dzen2
first, i want to explain some things.
I know i could have used conky, but my intention was to expand my knowledge of bash, pipes and redirections inside a script, and to have fun... (14 Replies)

Hi,
How can I find total CPU usage in percentage? e.g. if my system has 8 CPUs and I want to list total usage for all of them, is it possible through a command?
I have tried some of the commands like top, mpstat, sar. The output of those commands has to be manipulated to derive the percentage... (14 Replies)
Hi Experts,
I am executing multiple instances(in parallel) of perl script on HP-UX box.
OS is allocating substantial amount of CPU to these perl processes,resulting higher cpu utilization.
Glance always shows perl processes are occupying majority of the CPU resource. It is causing slower... (2 Replies)
Hi All,
I have a script which does report the cpu usuage, there are few output parameter/fields displayed from the script. My problem is I have monitor the output and decide
which cpu number (column 2) has maximum value (column 6).
Since the output is displayed/updated every seconds, it's very... (1 Reply)
Hello Friends,
I am trying to create a shell script which will check the CPU utilization. I use command top to check the %CPU usage. It give s me below output
Cpu states:

Hi all
I was wondering if its possible to write a script to keep CPU usage at 90%-95%? for a single cpu linux server?
I have a perl script I run on servers with multple cpu's and all I do is max all but one cpu to get into the 90'% utilised area. I now need a script that raises the CPU to... (4 Replies)
Hi,
Recently i have write a simple script to capture CPU high usage based on prstat but i found out that it did capture correctly. I need to capture the rows that contains CPU usage more than 3%. Below line which i thought will capture CPU usage based CPU column in prstat(9th parameter) which is... (3 Replies)

DESCRIPTION
The machine-independent kcpuset subsystem provides support for dynamic processor sets. Conceptually kcpuset can be understood to be the ker-
nel equivalent of the user space cpuset(3) interface.
FUNCTIONS
kcpuset_create(retkcp, zero)
The kcpuset_create() function creates a dynamic CPU set and stores the result to retkcp. If the boolean zero is not false, the
allocated set is also initialized to zero.
kcpuset_destroy(kcp)
Destroys the CPU set kcp and schedules any linked CPU sets for deferred destruction.
kcpuset_copy(dkcp, skcp)
Copies the CPU set pointed by skcp to dkcp.
kcpuset_use(kcp)
Marks kcp as being in use by increasing the reference count of the object. Note that initially kcpuset_create() sets the reference
count to 1.
kcpuset_unuse(kcp, lst)
Decreases the internal reference count of kcp, and on the last reference (when the count reaches zero), destroys kcp. If lst is not
NULL, then instead of destroying, kcp will be added to the lst list for a deferred destruction.
kcpuset_copyin(ucp, kcp, len)
Copies the len bytes long user-space CPU set ucp to the kernel CPU set kcp.
kcpuset_copyout(kcp, ucp, len)
Copies the kernel CPU set kcp to the user-space CPU set ucp.
kcpuset_zero(kcp)
Clears the set kcp.
kcpuset_fill(kcp)
Fills the whole set kcp with ones.
kcpuset_set(kcp, cpu)
Adds cpu to the set kcp.
kcpuset_clear(kcp, cpu)
Removes cpu from the set kcp.
kcpuset_isset(kcp, cpu)
Returns 1 if cpu is part of the CPU set kcp.
kcpuset_iszero(kcp)
Returns true if the set kcp is empty.
kcpuset_match(kcp1, kcp2)
Compares the sets kcp1 and kcp2, returning true if these are identical.
kcpuset_merge(kcp1, kcp2)
Merges the set kcp2 to the set kcp1.
kcpuset_atomic_set(kcp, cpu)
The kcpuset_atomic_set() function operates as kcpuset_set(), but the operation is atomic; see atomic_ops(3) for more details.
kcpuset_atomic_clear(kcp, cpu)
Removes cpu from the CPU set kcp atomically.
