For monitoring: nmon (1..10), xymon (10...100), nagios (50...) (number of monitored systems)
For an ad-hoc snapshot and debugging, I suggest the Posix format where you can specify the columns.

Hi ,
I am running a C/C++ program on a solaris 5.8 machine. This parituclar application has a module which saves data to a file. The module uses fwrite() function to save data.
The fwrite function write about 500 MB of data to a file. The problem which I am facing is, the memory consumtion... (2 Replies)
Dear all,
When I write the daemon programs it is consuming high memory and processor time. How can I avoid this?
But, the system daemons are not consuming more. How?
Can any one explain how the system daemons are handling the memory consumption and processor time.

HI All,
Can anyone send me a command to find TOP 5 Memory consuming process.
It would be lelpful if I get output something like below

I tried few commands from the internet but the result only give the real memory usage or pagging, I want total... (4 Replies)
Hi all,
We have a server having much processes running. It is very difficuilt to trace the exact consuming more memory. Howerver, it shows CPU usage in sequence but how memory?
Tried working with TOP command.
Please let me know if something not clear.

Hi All,
We have a Linux (RHEL5) server hosting Oracle database.
Usually, Memory utilization will by 50 % and CPU utilization will be 20%.
In the last three days, volume of load was high and now back to normal.
Is it possible to check the Memory (RAM) utilization and CPU utilization in %... (1 Reply)
Hi All
what is the command to check process ids , which are running from long time and which are consuming more cpu?
Also how to check, what a particular PID is running what

if i want to check what is this... (1 Reply)
When I run 'top' command,I see the following
Memory: 32G real, 12G free, 96G swap free
Though it shows as 12G free,I am not able to account for processes that consume the rest 20G.
In my understanding some process should be consuming atleast 15-16 G but I am not able to find them.

wait
WAIT(1) BSD General Commands Manual WAIT(1)NAME
wait -- await process completion
SYNOPSIS
wait [pid]
DESCRIPTION
If invoked with no arguments, the wait utility waits until all existing child processes in the background have terminated.
Available operands:
pid If a pid operand is specified, and it is the process ID of a background child process that still exists, the wait utility waits until
that process has completed and consumes its status information, without consuming the status information of any other process.
If a pid operand is specified that is not the process ID of a child background process that still exists, wait exits without waiting
for any processes to complete.
The wait utility exits with one of the following values:
0 The wait utility was invoked with no operands and all of the existing background child processes have terminated, or the process
specified by the pid operand exited normally with 0 as its exit status.
>0 The specified process did not exist and its exit status information was not available, or the specified process existed or its exit
status information was available, and it terminated with a non-zero exit status.
If the specified process terminated abnormally due to the receipt of a signal, the exit status information of wait contains that termination
status as well.
STANDARDS
The wait command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
