If not, check for bad lines. Legal Notices Review your favorite Linux distribution. For disks, this value includes seek times, rotational latency times, and data transfer times.
Thomas Bastian was a coauthor of an earlier version of this document.The earlier version of this page has been published in the "The Developers Edge" in 2009. ‹ Process Introspection up 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.

Saturation - The run queue length from vmstat (kthr:r) can be used as a measure of CPU saturation, as can CPU latency time from prstat -m. Solaris Prstat One clearly identifies a high-system time usage (61%) for the process cc_sys. The columns USR through LAT sum to 100% of the time spent for each thread during the prstat sample. Why didn't Dumbledore appoint the real Mad Eye Moody to teach Defense Against Dark Arts?
Linux and Solaris have vmstat, which shows combined CPU utilization across all virtual processors. https://www.cyberciti.biz/faq/unix-command-to-find-cpu-utilization/ A Java process showing high CPU utilization with prstat -mL can be mapped to a Java process and Java thread(s) on Solaris through a sequence of steps using prstat, pstack, and How To Check Memory Utilization In Solaris Let's once again, start two (2) copies of our CPU intensive application. Solaris Mpstat It's free: ©2000-2017 nixCraft.

Get notified when the disk space falls below the margin. blks/s Number of 512-byte blocks that are transferred to the device, per second. Top Command In Sun Solaris
The system always shows 90% CPU idle time and more than 20 G free memory. Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the Microstate accounting - High-resolution time counters track several states for user threads; prstat -m reports the results.

Copyright © 1998, 2011, Oracle and/or its affiliates. Solaris Sar The process statistics tool, prstat, reports the per-thread microstates for user processes. $ prstat -mL PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/LWPID 25644 What is this apartment in which the Terminator fixes himself?
How to Check Swapping Activity (sar -w) Use the sar -w command to report swapping and switching activity.$ sar -w 00:00:00 swpin/s bswin/s swpot/s bswot/s pswch/s 01:00:00 0.00 0.0 0.00 0.0 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. RSS: the resident set size of the process (RSS), in kilobytes (K), megabytes (M), or gigabytes (G). Solaris Performance Monitoring Commands prstat uses procfs, the /proc file system, to fetch process details (see proc(4)), and the getloadavg() syscall to get load averages. $ prstat PID USERNAME SIZE RSS STATE PRI NICE TIME
Some basic investigation shows the CPU to be idle, lots of memory to be available, no swapping, no I/O, but a high average load. Got log in issue on web application when it happens. lg_mem The amount of memory, in bytes, that the KMA has available in the large memory request pool. have a peek here in argument of macro or environment Is there any way to take stable Long exposure photos without using Tripod?
Clearly in this example, both CPU bound applications are fighting for the one CPU of the test system, resulting in high waiting times (latency) to gain access to a CPU. The “id” column shows the percentage of idle or available CPU. The prstat column LCK reports on percentage of time spent waiting on user locks. solaris performance share|improve this question edited Mar 1 '12 at 13:38 asked Feb 29 '12 at 20:35 Spiff 181116 Weird.
Access system activity data on a special request basis. sread/s The number of read system calls per second. I want to find the total CPU usage on a server. If you have non-global zones in 10, use prstat -Z to see the breakdown by zones.
Which processes (or users, zones, projects, tasks) are utilizing my system? These entries measure the effectiveness of system buffering. Any driver or module that uses KMA resources, but does not specifically return the resources before it exits, can create a memory leak.

As a result, the first row of data from vmstat is most often ignored. fail The number of requests for small amounts of memory that failed. Reply Link drdaco September 9, 2010, 7:40 pmLokesh,Unless your application is already parallelized, there is no way to force it to use more than one CPU. If the number is greater than 1, you might need to increase memory.
The columns of interest for monitoring CPU utilization are shown in bold.
