I can get a count using vmstat, but I need to know what processes/threads are in there. Beware that sampling artifacts will probably prevent to get accurate matches.

The following output is an example from a system with 32 CPUs. $ mpstat 1 CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl cc_lck 0 – running in ideal conditions Now let's observe the per-thread microstates.

The following example shows the default output of sar, which is also the -u option to sar. RSS: the resident set size of the process (RSS), in kilobytes (K), megabytes (M), or gigabytes (G). inod-sz The total number of inodes in memory compared to the maximum number of inodes that are allocated in the kernel.
In this example, we can see that on average each thread is waiting for CPU resource about 80% of the time. Example11-9 Checking Page-Out and Memory (sar -g) The following example shows output from the sar -g command.$ sar -g SunOS balmy 5.10 Generic_144500-10 sun4v ... 00:00:00 pgout/s ppgout/s pgfree/s pgscan/s %ufs_ipf This situation implies that more memory might be needed. %ufs_ipf The percentage of ufs inodes taken off the free list by iget that had reusable pages that are associated with them. Solaris Load Average Explained rcvin/s Receiver hardware interrupts per second.
Some of the components that are monitored in Solaris are: CPU Utilization Monitor CPU usage - check if CPUs are running at full capacity or are they being underutilized. Solaris Cpu Usage By Process The CPUs are shared by applications on the system, according to a policy prescribed by the operating system and scheduler (see Chapter 3 in Solaris Internals). The buffer is used to cache metadata. Source dirbk/s The number of directory block reads issued per second.

They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. prstat -c 2 > prstat.txt). How To Check Memory Utilization In Solaris SIZE: the total virtual memory size of the process, including all mapped files and devices, in kilobytes (K), megabytes (M), or gigabytes (G). Top Command In Sun Solaris Reply Link Sadequl Ghani February 12, 2008, 10:15 amHow to install pine in Sun Solaris 10.5 under UNIX env?
Welcome to LQ. weblink When a reporting interval is given, the first row of statistics is a summary of all data collected since the system was last booted.Other popular alternatives to vmstat on Solaris and prstat – prstat -J 2 reports about projects Special Report – by Tasks (see newtask(1)) With the option -T to prstat, additional reports about tasks are printed. Did Joseph Smith “translate the Book of Mormon”? Solaris Mpstat
Many modern systems from Sun boast numerous CPUs or virtual CPUs (which may be cores or hardware threads). The prstat column LCK reports on percentage of time spent waiting on user locks. This example shows that all tables are large enough to have no overflows. http://silkiconfinder.com/cpu-usage/ps-linux-command-cpu-usage.html Privacy - Terms of Service - Questions or Comments UNIX & Linux Forums > Operating Systems > Solaris Member Name Remember Me?
r+w/s Number of read-and-write transfers to the device, per second. Solaris Sar These faults are known as validity faults. We solved the problem by putting the loaded content in a cache region, reducing drastically the number of network calls to the underlying server.
The important microstates for CPU utilization are USR, SYS, and LAT. The system always shows 90% CPU idle time and more than 20 G free memory. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. Command To Check Cpu Utilization In Linux You can find Top packages for Solaris and I find so of my users prefer that due to familiarity with it versus prstat and other Solaris options.
Any driver or module that uses KMA resources, but does not specifically return the resources before it exits, can create a memory leak. Each thread contributes an average of 0.017 to your 1-minute load average, which is quite reasonable. –Alexios Mar 1 '12 at 13:51 Nothing unusual with dmesg (as far as Please visit this page to clear all LQ-related cookies. his comment is here Are you new to LinuxQuestions.org?
If the system becomes CPU resource limited, then application or kernel threads have to wait on a queue to be scheduled on a processor, potentially degrading system performance. Both versions of vmstat optionally take a reporting interval, in seconds, as a command line argument. The columns of interest for monitoring CPU utilization are shown in bold. Hot Network Questions Is it a security vulnerability if the addresses of university students are exposed?
Both prstat and top are good tools for providing a high level view of CPU utilization at a per process level. pflt/s The number of page faults from protection errors. Typically, this value should be less than 2. Delivers both historical and current Solaris performance metrics, providing insight into the performance over a period of time.
Password Home Search Forums Register Forum RulesMan PagesUnix Commands Linux Commands FAQ Members Today's Posts Solaris The Solaris Operating System, usually known simply as Solaris, is a Unix-based operating system introduced The USR and SYS columns are the user and system time that this thread spent running on the CPU. prstat – observing latency with CPU intensive application Now let's run prstat with microstate accounting reporting, i.e. The larger the reported values for these operating system routines, the more time the kernel is spending to access user files.
