Glance PLUS is going to do what you need, but you'll have to pay for it depending of the version of HP-UX you have. I know that it comes with the Enterprise OE version of HP-UX but you have to buy a pack for Foundation OE version.
Can you please tell me how to find out System Memory (RAM) for a AIX unix server?
The command prtconf will do for Solaris but I don't know for AIX Unix. (1 Reply)

Hi.
I've just started to get into UNIX.
Researched on the Net, found out that most of the UNIX variants are not offered online.
1. Any of you guys know where I could obtain them on the Net? or anywhere at all?
2. Does learning a UNIX variant enough to cover an understanding of other UNIX... (6 Replies)
I don't know if this is better suited for the application section, but here goes.
We are currently running HP-UX 11 as our database server. The database is Progress version 9.1C.
As of late, some of our batch processes that run on the UNIX db server are erroring out because of what appear to... (3 Replies)
Hi!!!
how can I obtain the consumed memory of a process?
nowadays i'm using ps -efo pid, pmem, comm,args ....
but the information is in percentage, is that correct?
so, i want to know how can obtain the consumed memory of a process in mb?
thanks in advance!

Hi,
I am creating monitoring scripts in HP unix for that i need CPU utilization and memory utilization in HP unix.
for CPU utilization i am using TOP command
for Memory utilizaion i am not able to use glance command in scripts.
means i am not able to redirect and stop.

Hi friends iam new to unix. how to extend memory in UNIx.
what are the possible scenarios to increase memory.
I just noticed we have swap memory also but when and how to use it. and what is the correct way to increase RAM. please provide information or some useful commands. Thanks (2 Replies)
So, I would ask you a piece of advice about which books or titles could give me comprehensive information about virtual memory in UNIX. Especially, I would found out that virtual address translation corresponds structures of kernel!
Thanks! (2 Replies)

vmstat
vmstat(1) General Commands Manual vmstat(1)Name
vmstat - report virtual memory statistics
Syntax
vmstat [ interval [ count ] ]
vmstat -v [ interval [ count ] ]
vmstat -fKSsz
vmstat -Kks namelist [ corefile ]
Description
The command reports statistics on processes, virtual memory, disk, trap, and cpu activity.
If is specified without arguments, this command summarizes the virtual memory activity since the system was last booted. If the interval
argument is specified, then successive lines are summaries of activity over the last interval seconds. Because many statistics are sampled
in the system every five seconds, five is a good specification for interval; other statistics vary every second. If the count argument is
provided, the statistics are repeated count times.
When you run the format fields are as follows:
Procs: information about numbers of processes in various states.
r in run queue
b blocked for resources (i/o, paging, and so on.)
w runnable or short sleeper (< 20 seconds) but swapped
faults: trap/interrupt rate averages per second over the last 5 seconds.
in (non clock) device interrupts per second
sy system calls per second
cs cpu context switch rate (switches/second)
cpu: breakdown of percentage usage of cpu time
us user time for normal and low priority processes
sy system time
id cpu idle time
Memory: information about the use of virtual and real memory. Virtual pages are considered active if they belong to processes which are
running or have run in the last 20 seconds.
avm active virtual pages
fre size of the free list
Pages are reported in units of 1024 bytes.
If the number of pages exceeds 9999, it is shown in a scaled representation. The suffix k indicates multiplication by 1000 and the suffix
m indicates multiplication by 1000000. For example, the value 12345 appears as 12k.
page: information about page faults and paging activity. These are averaged every five seconds, and given in units per second. The size
of a unit is always 1024 bytes and is independent of the actual page size on a machine.
re page reclaims (simulating reference bits)
at pages attached (found in free list not swapdev or filesystem)
pi pages paged in
po pages paged out
fr pages freed per second
de anticipated short term memory shortfall
sr pages scanned by clock algorithm, per-second
disk: s0, s1 ...sn: Paging/swapping disk sector transfers per second (this field is system dependent). Typically paging is split across
several of the available drives. This will print for each paging/swapping device configured into the kernel.
Options-f Provides reports on the number of forks and vforks since system startup and the number of pages of virtual memory involved in each
kind of fork.
-K Displays usage statistics of the kernel memory allocator.
-k Allows a dump to be interrogated to print the contents of the sum structure when specified with a namelist and corefile. This is
the default.
-S Replaces the page reclaim (re) and pages attached (at) fields with processes swapped in (si) and processes swapped out (so).
-s Prints the contents of the sum structure, giving the total number of several kinds of paging related events that have occurred since
boot.
-v Prints an expanded form of the virtual memory statistics.
-z Zeroes out the sum structure if the UID indicates root privilege.
Examples
The following command prints what the system is doing every five seconds:
vmstat 5
To find the status after a core dump use the following:
cd /usr/adm/crash
vmstat -k vmunix.? vmcore.?
