Prstat

Hi , I am on solaris 10 sparc64, I need to know how i can check the exact memory utilization by a process/application running on my server..
prstat doesn't give this info , neither it gives the memory/cpu utilization info as we get from Top...
I know my application is always running but still it doesn't show in prstat , and I see most sleep process in prstat by root.
Thanks

To get a detailed/accurate number, including any ISM/DISM segments, use pmap(1M), eg:
$ pmap -x 10301
10301: -bash

Using dtrace how can we get the functionality of prstat ,vmstat

Hi,
I would like to know what probes can be used to generate a dtrace (.d) script which could produce the output of prstat,vmstat etc.I cannot use these commands at the command prompt directly to know my system's behavior.Can any one here help me out to get this thing realized.I have stiff deadlines to meet .....and i am behind them already...
Thanking for your support in advance.
Karthik

There's probably not an exact equivalent. I'd start with the 'dtrace toolkit' and see if there's something in there that meets your needs.
But it's not designed to replace tools that already work well. Why would you be able to use dtrace and not vmstat?

Please assist - strange prstat / unable to kill process (-9)

Hi Guys,
I have some questions and I hope someone here will be able to help. Kindly refer to below for my prstat output.
1. I have this ora10g process taking 8.3 CPU (sftp-server2/1). Just now, our dba attempted to perform a sftp from a remote macine to this machine, however, the process has already been terminated. We tried to perform a kill -9 <pid>, however, the process is still there? Any other way to kill it since rebooting the mission critical server is not an option.
2. From prstat -a, we can see the total RSS by ora10g is 362G. It won't be possible right as our server has only 32 GB of memory. Anyone can advise? Is it normal?

Prstat output question

Hi all,
I have 2 problems I don't manage to explain when running prstat on Solaris 8 :
1- prstat does not see fsflush process !!!!
You can even try to force it : prstat -p 3 : it won't work...
2- prstat -a differs from prstat -aL when you look at TIME (and MEMORY) value for each user
Does anybody know the reason why ???
Thanks,
Jerome

Thanks for your answer about processes 0, 2 and 3
I found the answer to my second question : bug 4481976 : prstat without -L reports wrong CPU time for multithreaded processes

Prstat -J cmd takes more time if there are around 800 processes & 300 user

Hi experts,
We used command 'prstat -J -n 1,100 -z global 1 1' to obtain the project statistics.
One of my customer who have around 800 processes with around 300 users facing problem on his machine whenver the above prstat command executed. As per his comments 'prstat' consuming high CPU and it taking much time to execute.
He has using machine with following configuraton:
SunOS <machine name> 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-V490
Is any one has face similar issue? Is it related to any OS patch?
Let me know any information regarding this.
Thanks,

The folks at NotebookCheck do the kind of benchmarks you reference. You can see their results at:
http://www.notebookcheck.net/Lenovo-ThinkPad-W550s-Workstation-Review.137989.0.html
The tests I ran were just to help me decide which laptop to use since I now have both.
I do use ATTO as well as CrystalDiskMark for disk/SSD read and write testing. Of course both go off the map when you enable RAPID in the Lenovo with the Samsung 850 Pro installed. RAPID does actually speed up work processing...not just wow the I/O test software.
I was getting about 550/450 MB/s read/write with both laptops before I enabled RAPID. With RAPID I get 3345 read and 1833 write with the Lenovo.
Too bad RAPID does not work with all Samsung SSD storage devices.

Question of the output of "prstat -a" on solaris 10

Hi, all
Recently, I'm debugging a memory issue on the solaris 10 system. I executed the command like "prstat -U root -n 200 -s rss -a" to list all root user memory consumption and sorted by rss. I'm sure that the total number of root process is less than 100. My target is to find which root process takes the memory most. However I'm concerning the output of the above command. The summary on the bottom of the command showed that the total RSS of root was about 4G, the NPROC was about 150. When I did a "sum" of the RSS of all 150 root processes, the value was 1.5G which was far less than the 4G on the bottom summary.
Does anyone know if my understanding is correct or not? Should they be identical?
Thanks

Because of the way Solaris allocates and reports memory usage it is often (very) hard to account for the different values reported by the various commands. Most often the differences involve shared memory.
Why do you think you have a memory problem?
Do you think the problem is with virtual or physical memory?

Prstat output in Solaris 11

Hi all,
Looking at prstat output in Solaris 11, something has clearly changed from Solaris 10 prstat version, since the results are quite different.
Looking at an x86 server with S11+SRU7.5, the Oracle instance is eating(RSS) 57GB memory from a machine that only has 14GB memory in total. Is RSS calculated now with used memory+swap? if so, whats the SWAP column for then?
NPROC USERNAME SWAP RSS MEMORY TIME CPU
82 root 2755M 2003M 3.3% 4:19:21 0.8%

5 daemon 36M 13M 0.0% 0:01:31 0.0%
RSS
The resident set size of the process (RSS), in kilobytes
(K), megabytes (M), or gigabytes (G). The RSS value is
an estimate provided by proc(4) that might underestimate
the actual resident set size. Users who want to get more
accurate usage information for capacity planning should
use the -x option to pmap(1) instead.

I hope it's a bug.
Have you seen bug 7117588. It reads in part:
"prstat should account for shared pages when counting RSS and swap for zones, projects, tasks, and users. It does not due so after the fix for 6522129."
I am not sure how to read this statement but I guess it is/was broke.

Where is the rest of my memory prstat -aL

When I add the RSS column should it total to my physical memory on the system. I have 80GB RAM on the system

If you have processes that utilize shared memory (like Oracle) the RSS for each process will reflect the shared memory allocation.

Running prstat non-interactively

Hi,
I'd like to be able to run "prstat" in background from a script and have the output redirected to a file.
It works fine when attached to the terminal, but I would like to run it from cron or call it from another script. When trying this, prstat starts dumping out the samples as fast as it can -- it ignores the delay parameter (e.g. 20 seconds/sample) I fed it. I think prstat is expecting terminal input and
is defective at running in this non-interactive mode. Is there any workaround for this problem?
thanks,
RichG

Hi,
This appears to be a known bug (id # 4529138). This is fixes in Solaris 9.
The workaround is to use the same command as a non-root user.

Solaris server hung when executes prstat or ps command

Hi all,
When we are executing prstat or pr command, the global zone and non global zone images are hungs.
kindly give some suggesstions to resolve

I've noticed huge latency while running prstat, ps type commands on certain systems running java-based applications.
This could be due to lock mgmt issues:

Why the "prstat -a" showed "incorrect" rss result?

Hi, folks
I was a little bit confused recently when I was investigating a memory issue as per the data collected by "prstat".
The output of the prstat looked like,
27465 nicgrp01 258M 175M cpu15   10    0 535:30:36 3.1% bsmciapp/9
7211 nicgrp01 258M 206M cpu9    10    0 14:20:25 3.1% bsmciapp/9
29482 nicgrp01 258M 197M cpu3    10    0 225:08:29 3.1% bsmciapp/9
but the summary looked like,
NPROC USERNAME SWAP   RSS MEMORY      TIME CPU
    27 nicgrp01 204M 427M 2.6% 775:10:35 9.4%
Obviously, the sum of rss of the username "nicgrp01" won't be 427M only...(note, we have total 27 processes of user nicgrp01, the top 3 of them have been using more than 427M rss already...)
As I know that the final result of the "prstat -a" will show the sum of CPU, Memory of the top N users (+# of processes of that user).
In which scenario, the sum will display the rss usage like above?
Appreciated if anyone can shed me a light here.
Thanks.

looks that they are sharing some memories.

Ps and prstat showing UIDs not usernames

Hey folks,
I have setup central authentication on 12 Solaris 9 machines using LDAP. The /etc/pam.conf and /etc/nsswitch.conf have been set to use LDAP.
Everything is working fine (users can login, finger, id, ssh, etc), except that on one of the machines, ps and prstat shows the UID number of the user, not the user's name. This only happens for non-root users. For root, ps and prstat show the usernames. For non-root users, the following errors are logged in /var/adm/messages when ps -ef is run:
Mar 1 10:48:33 sun-1 ps[5172]: [ID 293258 user.error] libsldap: Status: 91 Mesg: openConnection: failed to initialize TLS security (security library: bad database.)

This is the output of ps -ef:

I have applied patch 112960-34 to fix some other ldap issues I was having. My other machines are not having this issue, but they also have different patch levels.
Has anyone else run into this and fixed it?
Any ideas would be appreciated.
Thanks,
Konstantin

It turns out that /var/run/name_service_door had insufficient permissions. It should be 444:
Dr--r--r--   1 root     root           0 Feb 24 17:37 name_service_doorTo permanently change this, change CMASK value in /etc/default/init to something like 022.

Prstat gets cut off

When I run the command prstat -u user 1 1 I get about 100 lines of output. Which is fine. But if I pipe or redirect the command it only comes back with about 15 lines. prstat -u user 1 1 |more still cuts it down. So trying to use prstat in a script, like uprstat found elsewere, gives inaccurate information. Any ideas?

From the man page:
-n ntop[,nbottom]
...When you specify the -c
option or direct the output to a file, the default
values for ntop and nbottom are 15 and 5.
'prstat -n 99999' fixes this
