I am using wordpress installation and using some standard plugins.
I have 400 visitors per hour and daily 1500 unique visitors. Database size is 50MB. but it has 1200 posts and 25,000 comments. I think it is creating number of connections when readers connects and stay long time on site for reading articles. I have not made any manual php files. everything is wordpress.
here is the output by running the following command :
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 all,
I tried to output memory usage information while the process is
executing at a particular time. I found out some people
suggesting calling the ioctl. I followed it and wrote a test example:
#include <unistd.h>
#include <stdlib.h>
#include <iostream.h>
#include <fcntl.h>
#include... (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

Hi all,
Can you please tell me the command, with which one can know the amount of space a specific directory has used.
df -k . ---> Displays, the amount of space allocated, and used for a directory.
du -k <dir name> - gives me the memory used of all the files inside <dir>

Hello Everyone,
I'm looking for a efficient script that monitors the memory usage on AIX and send email alerts when it reaches certain point.
Q) need to get alerts, when the memory usage exceed 90% on AIX?
or
Q) Need to get alerts when available free Memory is 1G or 10% etc
Any idea... (3 Replies)
Let's say i have 20 users logged on Server. How can I know how much memory percent used each of them is using with system time in each user? (2 Replies)
Hello Friends,
I need to check memory usage & availability before I could run a program if there is enough memory is left or not, so how could i achieve this? Which command output i should rely on? I have diplayed outputs of SAR, VMstat and PRstat commands below, But how could i check memory... (8 Replies)
I can't check actual memory usage in the Redhat 5.5...
The used memory is 14214 Mb of Total 15919 by Free -m command.
I sum the RSS value on PS aux command result and the value is 5428.66Mb.
Yes It's quite different actual usage memory and RSS value.
So I added Shared memory value... (5 Replies)

bcopy
bcopy(9F) Kernel Functions for Drivers bcopy(9F)NAME
bcopy - copy data between address locations in the kernel
SYNOPSIS
#include <sys/types.h>
#include <sys/sunddi.h>
void bcopy(const void *from, void *to, size_t bcount);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
from Source address from which the copy is made.
to Destination address to which copy is made.
bcount The number of bytes moved.
DESCRIPTION
bcopy() copies bcount bytes from one kernel address to another. If the input and output addresses overlap, the command executes, but the
results may not be as expected.
Note that bcopy() should never be used to move data in or out of a user buffer, because it has no provision for handling page faults. The
user address space can be swapped out at any time, and bcopy() always assumes that there will be no paging faults. If bcopy() attempts to
access the user buffer when it is swapped out, the system will panic. It is safe to use bcopy() to move data within kernel space, since
kernel space is never swapped out.
CONTEXT
bcopy() can be called from user or interrupt context.
EXAMPLES
Example 1: Copying data between address locations in the kernel:
An I/O request is made for data stored in a RAM disk. If the I/O operation is a read request, the data is copied from the RAM disk to a
buffer (line 8). If it is a write request, the data is copied from a buffer to the RAM disk (line 15). bcopy() is used since both the RAM
disk and the buffer are part of the kernel address space.
1 #define RAMDNBLK 1000 /* blocks in the RAM disk */
2 #define RAMDBSIZ 512 /* bytes per block */
3 char ramdblks[RAMDNBLK][RAMDBSIZ]; /* blocks forming RAM
/* disk
...
4
5 if (bp->b_flags & B_READ) /* if read request, copy data */
6 /* from RAM disk data block */
7 /* to system buffer */
8 bcopy(&ramdblks[bp->b_blkno][0], bp->b_un.b_addr,
9 bp->b_bcount);
10
11 else /* else write request, */
12 /* copy data from a */
13 /* system buffer to RAM disk */
14 /* data block */
15 bcopy(bp->b_un.b_addr, &ramdblks[bp->b_blkno][0],
16 bp->b_bcount);

WARNINGS
The from and to addresses must be within the kernel space. No range checking is done. If an address outside of the kernel space is
selected, the driver may corrupt the system in an unpredictable way.
