Apache Proxy Config. Field Name Description sml_mem The amount of memory, in bytes, that the KMA has available in the small memory request pool. That said, you can get an approximation by looking at the STAT (state) field of the process list from ps. avque Average number of requests during the time the device was busy servicing a transfer request. http://supportcanonprinter.com/cpu-usage/how-to-check-cpu-usage-in-solaris.html

- A high number of cycles, combined with high values for the pgfree/s and pgscan/s fields, indicates a memory shortage.
- The following example shows the default output of sar, which is also the -u option to sar.
- These entries measure the effectiveness of system buffering.

prstat reports the per-process (option -m) or per-thread (option -mL) microstates. cc_lck 10 – prstat output Now the picture looks different. It's free: ©2000-2017 nixCraft. https://docs.oracle.com/cd/E23824_01/html/821-1451/spmonitor-8.html Again, let's observe the microstates.

How To Check Memory Utilization In Solaris How do I find out CPU Utilization under Sun Solaris UNIX?A. Solaris Mpstat Why leave magical runes exposed?
If namei does not find a directory name in the DNLC, it calls iget to get the inode for either a file or directory. this contact form The “id” column shows the percentage of idle or available CPU. The oversized requests are satisfied by allocating memory from the system page allocator. Preserving Vertices Detect MS Windows Did Joseph Smith “translate the Book of Mormon”? Top Command In Sun Solaris
If no reporting interval is given to mpstat, the reported output is a summary of all mpstat data collected since the system was last booted. 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). Looking at the line with PID 1311 (display middle), one can see the microstates for LWP #9 and LWP #8 of the process firefox-bin. have a peek here 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.
fork/s The number of fork system calls per second, which is about 0.5 per second on a system with 4 to 6 users. Sar Command In Solaris Field Name Description device Name of the disk device that is being monitored. %busy Portion of time the device was busy servicing a transfer request. If %busy is small, large queues and service times probably represent the periodic efforts by the system to ensure that altered blocks are promptly written to the disk.
freeswap The number of 512-byte disk blocks that are available for page swapping.
The following list describes output from the -u option:%usr Lists the percentage of time that the processor is in user mode. %sys Lists the percentage of time that the processor is Should we kill the features that users are not using frequently, to improve performance? The following example illustrates how to do this.

For each CPU, a set of event counts and utilization statistics are reported. A memory leak causes the amount of memory that is allocated by KMA to increase over time. The columns USR through LAT sum to 100% of the time spent for each thread during the prstat sample. Special report – Continuous Mode With the option -c to prstat, new reports are printed below previous ones, instead of overprinting them.
I can't use dtrace as I am on Solaris 9. –Vasu Feb 17 '10 at 13:15 add a comment| Your Answer draft saved draft discarded Sign up or log in What is the "crystal ball" in the meteorological station? The remaining time is spent in computation as expected (USR microstate). DTrace analysis - DTrace can analyze CPU consumption in depth and can measure events in minute detail.
General Sun, SunOS and Sparc related questions also go here. A couple of the more common ones are prstat for Solaris and top for Linux.Linux top reports not only CPU utilization but also process statistics and memory utilization. UNIX is a registered trademark of The Open Group. Example11-17 Checking Swap Activity (sar -w) The following example shows output from the sar -w command. $ sar -w 00:00:04 swpin/s bswin/s swpot/s bswot/s pswch/s 01:00:00 0.00 0.0 0.00 0.0 132
