Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started 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. All rights reserved. If no reporting interval is given to vmstat, the reported output is a summary of all CPU utilization data collected since the system has last been booted. this content
Any driver or module that uses KMA resources, but does not specifically return the resources before it exits, can create a memory leak. Got log in issue on web application when it happens. Paging out (the po column in vmstat) happens frequently as UNIX prepares for the possibility of a page-in. Remember, it is not a cause for concern when the user + system CPU values approach 100 percent. http://www.linuxquestions.org/questions/solaris-opensolaris-20/how-to-check-the-cpu-usage-in-solaris-610079/
Validity faults occur when a valid process table entry does not exist for a given virtual address. You are currently viewing LQ as a guest. lock-sz The number of shared memory record table entries that are currently being used, or allocated, in the kernel. This will display the total amount of RAM available, and will also show the usage of both RAM and virtual memory: L 5-17 root> top 9:43am up 16 days, 22:33,

Detecting Potential I/O Bottlenecks in AIX Using IBM's AIX dialect of UNIX, an I/O bound database server is usually evidenced by a high value in the wa (wait) column of vmstat. Solaris Load Average Explained It is useful here because it indicates both CPU utilization and saturation on one line. $ vmstat 5 kthr memory page disk faults cpu r b w swap free re mf

Reports can be grouped and displayed based on availability, health, and connection time. have a peek at this web-site 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
Hence, you may see vmstat page-in's when a large number of programs are starting and allocating their RAM memory. Solaris Prstat If %rcache falls below 90 percent, or if %wcache falls below 65 percent, it might be possible to improve performance by increasing the buffer space. Thus, this field represents the percentage of igets with page flushes. If you have non-global zones in 10, use prstat -Z to see the breakdown by zones.

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. 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. ADVERTISEMENTThe “us” column shows the percentage of user CPU utilization. http://computerhelpdev.com/cpu-usage/cpu-usage-command-in-solaris-10.php If you'd like to contribute content, let us know.

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 Performance Monitoring Commands 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.
