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
1- Function that tells how much memory used by current process
2- Function that tells how much memory used by all running processes
3- Function that tells how much CPU is used by current process
4- Function that tells how... (1 Reply)
Hi,
I can have only one instance of my script running at any point of time. So I have :
SCRIPT_NAME=$0
if ; then
echo "The process $0 is already running. Aborting the current instance of the job $0"
exit 1
fi
And in the last line of the script i had given exit 0
At times, though... (3 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
I am not able to understand the usage of d# in the below variable declaration.
FILE_LOC contains the directory path
And also help me to know about what will be saved in the variable j.
Thanks!!!
j=${d#${FILE_LOC}/} (2 Replies)
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>
But i... (2 Replies)
I recently came across this construct that i am not able to understand.
ex: cat $(grep -l 'HELLO' *)
the above command prints out the contents of the file if HELLO string is present in the file. I am not able to understand the usage of "$(" here.. can anybody help me understand this? $anything... (2 Replies)

Description
The and functions return trigonometric functions of radian arguments x for double data types.
The and functions return trigonometric functions for float data types.
The and functions return the arc sine in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc cosine in the range 0 to pi for double and float data types, respectively.
The and functions return the arc tangent in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc tangent of y/x in the range -pi to using the signs of both arguments to determine the quadrant of the
return value for double and float data types, respectively.
Error (due to roundoff)
When P stands for the number stored in the computer in place of pi = 3.14159 26535 89793 23846 26433 ... . and "trig" stands for one of
"sin", "cos" or "tan", then the expression "trig(x)" in a program actually produces an approximation to trig(x*pi/P), and "atrig(x)"
approximates (P/pi)*atrig(x). The approximations are close.
P differs from pi by a fraction of an ulp; the difference is apparent only if the argument x is huge, and even then the difference is
likely to be swamped by the uncertainty in x. Every trigonometric identity that does not involve pi explicitly is satisfied equally well
regardless of whether P = pi. For example, sin(x)**2+cos(x)**2 = 1 and sin(2x) = 2sin(x)cos(x) to within a few ulps regardless of how big
x is. Therefore, the difference between P and pi is unlikely to effect scientific and engineering computations.
Return Values
All the double functions return NaN if NaN is passed in.
If |x| > 1 then (x) and (x) will return the default quiet NaN.
The function defines (0,0) = NaN.
