About your swap configuration:
Since we dont know what external storage you use (if its the case...), I will figure out that your swap devices were not dreated at the same time and are here to correct memory access trouble of the beginning.
What will happen if you were to use the swap now? It will take the biggest first...
The impact? Your biggest is huge with only one access (unless its a multidisk striped device...) and two devices on the same root disks is not a good idea...
About CPU, Methyl and I have same way of seeing things: Not knowing what is running at what moment and for how long, you CANNOT diagnose what you have as an issue, Im tempted to say your thresholds are badly set...
I never had any serious trouble with the HP servers I managed at the time for I knew what was running on them and could ( and NOT a software ) see just by leaving glance running and looking time to time if things where normal or not... some strong calculations of stats can take 100%CPU during days (Yes! days...) a RDBMS transaction lasting hours is very suspicious but only the DBA can tell if normal or not
One classical issue figure is the box that "freezes" periodically with 100% CPU and I/O...
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

2- Function that tells how much memory used by all running processes

4- Function that tells how... (1 Reply)
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

did(7) Sun Cluster Device and Network Interfaces did(7)NAME
did - user configurable disk id driver
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
Disk ID (DID) is a user configurable pseudo device driver that provides access to underlying disk, tape, and CDROM devices. When the
device supports unique device ids, multiple paths to a device are determined according to the device id of the device. Even if multiple
paths are available with the same device id, only one DID name is given to the actual device.
In a clustered environment, a particular physical device will have the same DID name regardless of its connectivity to more than one host
or controller. This, however, is only true of devices that support a global unique device identifier such as physical disks.
DID maintains parallel directories for each type of device that it manages under /dev/did. The devices in these directories behave the same
as their non-DID counterparts. This includes maintaining slices for disk and CDROM devices as well as names for different tape device
behaviors. Both raw and block device access is also supported for disks by means of /dev/did/rdsk and /dev/did/rdsk.
At any point in time, I/O is only supported down one path to the device. No multipathing support is currently available through DID.
Before a DID device can be used, it must first be initialized by means of the scdidadm(1M) command.
IOCTLS
The DID driver maintains an admin node as well as nodes for each DID device minor.
No user ioctls are supported by the admin node.
The DKIOCINFO ioctl is supported when called against the DID device nodes such as /dev/did/rdsk/d0s2.
All other ioctls are passed directly to the driver below.
FILES
/dev/did/dsk/dnsm block disk or CDROM device, where n is the device number and m is the slice number
/dev/did/rdsk/dnsm raw disk or CDROM device, where n is the device number and m is the slice number
/dev/did/rmt/n tape device , where n is the device number
/dev/did/admin administrative device
/kernel/drv/did driver module
/kernel/drv/did.conf driver configuration file
/etc/did.conf scdidadm configuration file for non-clustered systems
Cluster Configuration Repository (CCscdidadm(1M) maintains configuration in the CCR for clustered systems
SEE ALSO devfsadm(1M), Intro(1CL), cldevice(1CL), scdidadm(1M)NOTES
DID creates names for devices in groups, in order to decrease the overhead during device hot-plug. For disks, device names are created in
/dev/did/dsk and /dev/did/rdsk in groups of 100 disks at a time. For tapes, device names are created in /dev/did/rmt in groups of 10
tapes at a time. If more devices are added to the cluster than are handled by the current names, another group will be created.
