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.
Thanks,... (1 Reply)
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
processname - pid - memory(in MB) - command
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.
Thanks,

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
For Ex:
i have a pid :3223722 which is running since from long time,
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.
Is... (1 Reply)
Hello
There are options / commands to check which process is consuming maximum memory
However is there any command/mechanism which will tell us which process was consuming maximum memory in specific time interval in the past?
I heard nmon report can help in this regard.
is there any... (5 Replies)

To find the most memory consuming processes, I tried the following 2 methods

pg2
pg2(3erl) Erlang Module Definition pg2(3erl)NAME
pg2 - Distributed Named Process Groups
DESCRIPTION
This module implements process groups. The groups in this module differ from the groups in the module pg in several ways. In pg , each mes-
sage is sent to all members in the group. In this module, each message may be sent to one, some, or all members.
A group of processes can be accessed by a common name. For example, if there is a group named foobar , there can be a set of processes
(which can be located on different nodes) which are all members of the group foobar . There are no special functions for sending a message
to the group. Instead, client functions should be written with the functions get_members/1 and get_local_members/1 to find out which pro-
cesses are members of the group. Then the message can be sent to one or more members of the group.
If a member terminates, it is automatically removed from the group.
Warning:
This module is used by the disk_log module for managing distributed disk logs. The disk log names are used as group names, which means that
some action may need to be taken to avoid name clashes.
EXPORTS
create(Name) -> void()
Types Name = term()
Creates a new, empty process group. The group is globally visible on all nodes. If the group exists, nothing happens.
delete(Name) -> void()
Types Name = term()
Deletes a process group.
get_closest_pid(Name) -> Pid | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_process, Name} | {no_such_group, Name}
This is a useful dispatch function which can be used from client functions. It returns a process on the local node, if such a
process exist. Otherwise, it chooses one randomly.
get_members(Name) -> [Pid] | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Returns all processes in the group Name . This function should be used from within a client function that accesses the group. It is
therefore optimized for speed.
get_local_members(Name) -> [Pid] | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Returns all processes running on the local node in the group Name . This function should to be used from within a client function
that accesses the group. It is therefore optimized for speed.
join(Name, Pid) -> ok | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Joins the process Pid to the group Name . A process can join a group several times; it must then leave the group the same number of
times.
leave(Name, Pid) -> ok | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Makes the process Pid leave the group Name . If the process is not a member of the group, ok is returned.
which_groups() -> [Name]
Types Name = term()
Returns a list of all known groups.
start()
start_link() -> {ok, Pid} | {error, Reason}
Types Pid = pid()
Reason = term()
Starts the pg2 server. Normally, the server does not need to be started explicitly, as it is started dynamically if it is needed.
This is useful during development, but in a target system the server should be started explicitly. Use configuration parameters for
kernel for this.
