Rather than statically allocating the maximum amount of memory it is expected to require under peak load, the KMA divides requests for memory into three categories: Small (less than 256 bytes) Solaris Prstat Load Averages Reply Gleb Reys says: January 18, 2016 at 12:28 pm Hi, you just add "1" to the end of the command line, this changes default interval from 5sec to 1sec Reply

LinuxQuestions.org > Forums > Other *NIX Forums > Solaris / OpenSolaris How to check the CPU usage in solaris? Prstat Linux reply RE:LCK Anonymous - 02/22/2012 - 18:43 I have a process with high LCK causing kernel contention in Solaris 10 (high smtx in mpstat, high sys/user ratio, high mutex_adenters in kstat The prstat column LCK reports on percentage of time spent waiting on user locks. The sar -g command also shows whether inodes are being recycled too quickly and causing a loss of reusable pages.
Instances of protection faults indicate illegal access to a page and "copy-on-writes." Generally, this number consists primarily of "copy-on-writes." vflt/s The number of address translation page faults, per second. http://stackoverflow.com/questions/2257489/solaris-cpu-run-queue dirbk/s The number of directory block reads issued per second. Prstat Command In Solaris When busy, the processor is in either user mode or system mode. Prstat Memory Usage In its simplest form, the command prstat

Thread-based microstate accounting tracks several meaningful states per thread in addition to user and system time, which include trap time, lock time, sleep time and latency time. Only processes in certain scheduling classes have a nice value. prstat – continuous report sorted by ascending other of CPU usage Special Report – by users With the option -a or -t to prstat, additional reports about users are printed. Check This Out Or is it only for the cpu that's holding that process?
alloc The amount of memory, in bytes, that the KMA has allocated from its large memory request pool to large memory requests. Man Prstat I can only say that in this scenario, sys time is increased because the process cannot get a mutex and it either do active wait (penalty for cpu time on user This is especially useful when gathering information to a file (i.e.
avserv Average time, in milliseconds, for a transfer request to be completed by the device. pri Sort by process priority. How to deal with an intern's lack of basic skills? Prstat Output To File A single page-in request, such as a soft-lock request (see slock/s) or a large block size, might involve paging-in multiple pages.
This site is not affiliated with Linus Torvalds or The Open Group in any way. pswch/s The number of kernel thread switches, per second. Access system activity data on a special request basis. this contact form alloc The amount of memory, in bytes, that the KMA has allocated from its small memory request pool to small memory requests.
While in the case of this sample application, the locking problems are obvious when looking at the source code, prstat microstate accounting capabilities can help pin-point locking weaknesses in larger applications. prstat– The Allround Utility One of the most important and widely used utility found in Solaris is prstat (see prstat(1)). The -a option is helpful for viewing how disk-dependent an application is. Example11-14 Checking Unused Memory (sar -r) The following example shows output from the sar -r command.$ sar -r SunOS balmy 5.10 Generic_144500-10 sun4v ... 00:00:04 freemem freeswap 01:00:00 44717 1715062 02:00:01
STATE: the state of the process (cpuN/sleep/wait/run/zombie/stop). prstat -c 2 > prstat.txt). In any case, if you want to precisely know what processes/threads are sitting in the run queue you'd rather go the dtrace way assuming you are running Solaris 10 or newer. I consider myself a power user, so won't even be claiming to be a prstat guru, but these command examples will hopefully teach you a thing or two.
A single page-out request might involve paging-out multiple pages. One clearly identifies a high-system time usage (61%) for the process cc_sys. In this pool, a large request is from 512 bytes to 4 Kbytes. The percentage of time that the queue is occupied. $ sar -q 00:00:00 runq-sz %runocc swpq-sz %swpoccThe following list describes the output from the -q option.runq-sz The number of kernel threads
