Problem is, if your machine is constantly using 100% of CPU (you should have atleast 5% for system).
In general, you need to find out what is being ran @ that time you saw a spike of CPU usage (database layer if db is used).
The tools for developers are : tusc, gdb and execution plans (db)
The tools for system folks are : sar, lsof, iostat, vmstat, glance
I would like to emphasize sar here, as a most useful tool (at least for me) for constant monitoring on HPUX systems. Have it run in cron collecting data all the time.
Something like :
Be sure to inspect the /usr/lbin/sa/sa1 script and select where you want the actual log (/var/adm/sa being default)
Then you will be able to inspect the files generated using sar -A -f /var/admsa/sadate
Check man sar for additional switches, there is plenty for everything.
There is also free software which will enable you to draw graphs from those files, or use awk to draw some conclusions.
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)
Please tell me solaris functions/api for getting following information

System FreeBSD.
Issue: I see that system idle = 0% in the same time top and other commands show that all process eat 0% of cpu.
System calls 98%
CPU states: 7.9% user, 0.0% nice, 91.8% system,<==!!!
But top does not show any process which eats more than 0%
Question: how can I see... (0 Replies)
Hi all,
When I have a below while loop in my code (This observation is same for C and Perl)
i= 0;
while(1)
{
i++;
}
for above the CPU uses goes beyond 49% on hp-ux machine, why cpu usage increase at this level for just a simple while loop?
and if I have a single print statement... (2 Replies)

Hi,
I want to monitor the current cpu usage, monitor usage , disk I/o and network utlization for solaris using SNMP.
I want the oids for above tasks.
can you please tell me that

Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

Hi all,
I'm using python and psutil a library to get system informations like cpu usage (percent) for a given process.
My question is if I have the value in % of the cpu usage how I could get the cpu usage in cycle number I mean not in percent?
Thanks a lot

sadc
sar(1M) System Administration Commands sar(1M)NAME
sar, sa1, sa2, sadc - system activity report package
SYNOPSIS
/usr/lib/sa/sadc [ t n] [ofile]
/usr/lib/sa/sa1 [ t n]
/usr/lib/sa/sa2 [-aAbcdgkmpqruvwy] [-e time] [-f filename] [-i sec] [-s time]
DESCRIPTION
System activity data can be accessed at the special request of a user (see sar(1)) and automatically, on a routine basis, as described
here. The operating system contains several counters that are incremented as various system actions occur. These include counters for CPU
utilization, buffer usage, disk and tape I/O activity, TTY device activity, switching and system-call activity, file-access, queue activ-
ity, inter-process communications, and paging. For more general system statistics, use iostat(1M), sar(1), or vmstat(1M).
sadc and two shell procedures, sa1 and sa2, are used to sample, save, and process this data.
sadc, the data collector, samples system data n times, with an interval of t seconds between samples, and writes in binary format to ofile
or to standard output. The sampling interval t should be greater than 5 seconds; otherwise, the activity of sadc itself may affect the sam-
ple. If t and n are omitted, a special record is written. This facility can be used at system boot time, when booting to a
multi-user state, to mark the time at which the counters restart from zero. For example, when accounting is enabled, the svc:/sys-
tem/sar:default service writes the restart mark to the daily data file using the command entry:
su sys -c "/usr/lib/sa/sadc /var/adm/sa/sa'date +%d'"
The shell script sa1, a variant of sadc, is used to collect and store data in the binary file /var/adm/sa/sadd, where dd is the current
day. The arguments t and n cause records to be written n times at an interval of t seconds, or once if omitted. The following entries in
/var/spool/cron/crontabs/sys will produce records every 20 minutes during working hours and hourly otherwise:
0 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
See crontab(1) for details.
The shell script sa2, a variant of sar, writes a daily report in the file /var/adm/sa/sardd. See the OPTIONS section in sar(1) for an
explanation of the various options. The following entry in /var/spool/cron/crontabs/sys will report important activities hourly during the
working day:
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A
FILES
/tmp/sa.adrfl address file
/var/adm/sa/sadd Daily data file
/var/adm/sa/sardd Daily report file

NOTES
The sar service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/sar
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
