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.

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.
Thanks in advance !!!! (1 Reply)
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(1M) System Administration Commands vmstat(1M)NAME
vmstat - report virtual memory statistics
SYNOPSIS
vmstat [-cipqsS] [disks] [ interval [count]]
DESCRIPTION
vmstat reports virtual memory statistics regarding kernel thread, virtual memory, disk, trap, and CPU activity.
On MP (multi-processor) systems, vmstat averages the number of CPUs into the output. For per-processor statistics, see mpstat(1M).
vmstat only supports statistics for certain devices. For more general system statistics, use sar(1), iostat(1M), or sar(1M).
Without options, vmstat displays a one-line summary of the virtual memory activity since the system was booted.
During execution of the kernel status command, the state of the system can change. If relevant, a state change message is included in the
vmstat output, in one of the following forms:
<<device added: sd0>>
<<device removed: sd0>>
<<processors added: 1, 3>>
<<processors removed: 1, 3>>
See System Administration Guide: Advanced Administration for device naming conventions for disks.
OPTIONS
The following options are supported:
-c Report cache flushing statistics. This option is obsolete, and no longer meaningful. This option might be removed in a future
version of Solaris.
-i Report the number of interrupts per device. count and interval does not apply to the -i option.
-p Report paging activity in details. This option will display the following, respectively:
epi Executable page-ins.
epo Executable page-outs.
epf Executable page-frees.
api Anonymous page-ins.
apo Anonymous page-outs.
apf Anonymous page-frees.
fpi File system page-ins.
fpo File system page-outs.
fpf File system page-frees.
When executed in a zone and if the pools facility is active, all of the above only report actitivity on the processors in the pro-
cessor set of the zone's pool.
-q Suppress messages related to state changes.
-s Display the total number of various system events since boot. count and interval does not apply to the -s option.
-S Report on swapping rather than paging activity. This option will change two fields in vmstat's ``paging'' display: rather than the
``re'' and ``mf'' fields, vmstat will report ``si'' (swap-ins) and ``so'' (swap-outs).
OPERANDS
The following operands are supported:
count Specifies the number of times that the statistics are repeated. count does not apply to the -i and -s options.
disks Specifies which disks are to be given priority in the output (only four disks fit on a line). Common disk names are id, sd,
xd, or xy, followed by a number (for example, sd2, xd0, and so forth).
interval Specifies the last number of seconds over which vmstat summarizes activity. This number of seconds repeats forever. inter-
val does not apply to the -i and -s options.
EXAMPLES
Example 1: Using vmstat
The following command displays a summary of what the system is doing every five seconds.

The fields of vmstat's display are
kthr Report the number of kernel threads in each of the three following states:
r the number of kernel threads in run queue
b the number of blocked kernel threads that are waiting for resources I/O, paging, and so forth
w the number of swapped out lightweight processes (LWPs) that are waiting for processing resources to finish.
memory Report on usage of virtual and real memory.
swap available swap space (Kbytes)
free size of the free list (Kbytes)
page Report information about page faults and paging activity. The information on each of the following activities is given in
units per second.
re page reclaims -- but see the -S option for how this field is modified.
mf minor faults -- but see the -S option for how this field is modified.
pi kilobytes paged in
po kilobytes paged out
fr kilobytes freed
de anticipated short-term memory shortfall (Kbytes)
sr pages scanned by clock algorithm
When executed in a zone and if the pools facility is active, all of the above (except for "de") only report activity on the
processors in the processor set of the zone's pool.
disk Report the number of disk operations per second. There are slots for up to four disks, labeled with a single letter and
number. The letter indicates the type of disk (s = SCSI, i = IPI, and so forth); the number is the logical unit number.
faults Report the trap/interrupt rates (per second).
in interrupts
sy system calls
cs CPU context switches
When executed in a zone and if the pools facility is active, all of the above only report actitivity on the processors in
the processor set of the zone's pool.
cpu Give a breakdown of percentage usage of CPU time. On MP systems, this is an average across all processors.
us user time
sy system time
id idle time
When executed in a zone and if the pools facility is active, all of the above only report actitivity on the processors in
the processor set of the zone's pool.

NOTES
The sum of CPU utilization might vary slightly from 100 because of rounding errors in the production of a percentage figure.
The -c option (Report cache flushing statistics) is not supported in this release.
