I'm having a little trouble understanding the output I'm seeing from kstat for the "net" class. I'm seeing a lot of entries with "mac" as the name, like this.
Does anyone know what the "mac" entry is for? I never saw this entry on any of my earlier boxes, and it seems to duplicate info from some of the other module names (opackets and ipackets for mac are the same as for my NIC bge0).
Any info on where I can find documentation or an explanation of this would be helpful.
I am learning output the data to a file using "ofstream". I need to read data from a file and output the result to the other file in 2 different ways. To do that I have to provoke two functions, and they have to output the result to the same text file. My problem is: they are correct on the screen... (2 Replies)
Hi,
I am looking for a cpu usage data (%usr, %iowait, %idle, %kernel) using kstat. The output of kstat is below. How do I interpret those numeric values? In other words, how do I calculate the percentage value using the values below?
Thanks a lot!

Hi all,
I am working on the symbEL to get some specific value from the kernel recently. But I am not sure whether kvm and kstat have such specific value. i checked the examples included with the RICHPse but didn't get the answer. also the "kstat" seems not have any description.

We used kstat on netra240/440 to check if the link is full duplex. So we do something like:
bash-3.00# kstat -pc net bge:1::/'link_duplex'/ | cut -f2

The output 2 indicates the link is full duplex. This kind of check worked all right for Netra 240/440 systems.
However, the nxge... (2 Replies)

Hi everyone--
I'm new to these forums and shell scripting, and I'm trying to write a script that checks if a particular ip is pingable
My idea was to check if the output of the command ping <some ip> -c 1 -w 1 had the string: "1 packet transmitted, 1 received"How would I go about doing this?... (2 Replies)

ks_update
ks_update(9E) Driver Entry Points ks_update(9E)NAME
ks_update - dynamically update kstats
SYNOPSIS
#include <sys/types.h>
#include <sys/kstat.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int prefix_ks_update(kstat_t *ksp, int rw);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
ksp Pointer to a kstat(9S) structure.
rw Read/Write flag. Possible values are
KSTAT_READ Update kstat structure statistics from the driver.
KSTAT_WRITE Update driver statistics from the kstat structure.
DESCRIPTION
The kstat mechanism allows for an optional ks_update() function to update kstat data. This is useful for drivers where the underlying
device keeps cheap hardware statistics, but extraction is expensive. Instead of constantly keeping the kstat data section up to date, the
driver can supply a ks_update() function which updates the kstat's data section on demand. To take advantage of this feature, set the
ks_update field before calling kstat_install(9F).
The ks_update() function must have the following structure:
static int
xx_kstat_update(kstat_t *ksp, int rw)
{
if (rw == KSTAT_WRITE) {
/* update the native stats from ksp->ks_data */
/* return EACCES if you don't support this */
} else {
/* update ksp->ks_data from the native stats */
}
return(0);
}
In general, the ks_update() routine may need to refer to provider-private data; for example, it may need a pointer to the provider's raw
statistics. The ks_private field is available for this purpose. Its use is entirely at the provider's discretion.
No kstat locking should be done inside the ks_update() routine. The caller will already be holding the kstat's ks_lock (to ensure consis-
tent data) and will prevent the kstat from being removed.
RETURN VALUES
ks_update() should return
0 For success.
EACCES If KSTAT_WRITE is not allowed.
EIO For any other error.
