AFAIK, AIX does not come with a ready-to-use script that triggers an alarm action when CPU or RAM consumption is above some threshold ;
( althought the `errpt' output may show some alerts if your 'dump device' is too small - but that's another story ... )
- however, your "CPU/RAM/Paging" info can all be gathered from the `vmstat' output ;
- give it a try, like :
Code:
$ vmstat 1 10
- this will give you ten samples of status, delayed one second each ;
- my suggestion is fairly simple :
1) with just a few `ksh' or `awk' lines in a script, you can check and alarm your needed values from the `vmstat' output ;
2) run the "vmstat + script" say, once every 5 minutes or so - with `crontab' - of course ;
- then all you have to worry is the way to actually 'inform' the events ( console , email , ... ) ;
ok ?
HTH
good luck, and success !

how can i monitor usages of CPU, Memory, Hard disk etc. under SUN Solaries
through a c program or java program
i want to store that data into database so i can show it graphically
thanks in advance (2 Replies)
Hi,
I want to check the CPU and Memory Utilisation in the whole machine (not for a single process). Can someone send me a ready made script which captures all information in a log every 5min??
Thanks,

i'm trying to find a way to monitor the CPU/Memory status of a solaris station using vmstat. I like to write a small script to periodically run vmstat and store the output. Can anyone show me how (preferrably in C++ if possible)? Thanks in advance. (6 Replies)
Hi all,
When you monitor the CPU and memory usage, how often do you do it ? Do it too often or too rarely will both cause the problem. So does anyone have hand-on experience ?
And for my case, the requirement says that when CPU usage is above X% or memory usage is above Y%, I should reject... (5 Replies)
Hi,
I need to write a script which would take the CPU and Memory usage at an interval of 10 mins. I tried using sar, but that does not solve my purpose.
Its not only one system that i have, but approximately 10 server from where i need to achive this date.
Can anyone share a script or idea... (1 Reply)
Hi,
I am relatively new to the cluster administration and shell scripting. I need help on a shell script which can help me determine how many cpu's over time, any particular ( or all registered users on a cluster ) are using. To generate data say over a period of week and list of users and their... (6 Replies)
Hi ,
I am new to scripting. please help me out how to write a script to monitor cpu , vmstat, iostat in Redhat linux. we are doing the load test.

Hi,
Linux redhat 5.5
I need to write a kshell script that shows all the process that consume 100% CPU (or more. strange but there are time that top shows higger value that 100) and they are active more than 5 minute.
The top command shows all the relevat information:

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.?
