Solaris zone memory usage

The memory usage collected by the CDM probe that is installed on Non-Global Solaris zones appear collect values from Global zone and need confirmation on how the memory usage is being calculated within Non-Global Solaris zones. See example below: Global Zone total memory used is approx 92%+ Non-Global zones Memory Usage of a Solaris Container (Zone) Last week one of my servers ran out of RAM and Swap. Shame on me for not monitoring that, but it's now. As the server is running several zones, my first question was: Which zone is eating up my RAM? So, here are the commands I used 12 Oracle Solaris Zones. Network usage is not available for each zone. Memory utilization - The memory utilization is the physical, virtual, and locked memory in use by each zone. File System Utilization - Whenever you create a zone, a zpool is created with the zone guest image name. The file system lists the root file system and other. Using the zonestat Utility in a Non-Global Zone. The zonestat utility reports on the CPU, memory, network, and resource control utilization of the currently running zones. Usage examples follow. For complete information, see zonestat(1).. The zonestat network component shows the usage of virtual network (VNIC) resources on PHYS, AGGR, Etherstub, and SIMNET data-links by zones

Display the zone's current memory cap: Display the zone's current usage (see the last two columns to view the total cap and the percentage of the cap currently in use): Solaris 10 - 11.1 # prctl -n zone.max-swap -v 48g -r -i zone zone1 # rcapadm -z zone1 -m 16g User Memory Usage : Overall Memory usage on system % vmstat -p 3 memory page executable anonymous filesystem swap free re mf fr de sr epi epo epf api apo apf fpi fpo fpf 1468048 508176 1 48 0 0 0 1 0 0 0 0 0 2 0 The only way to see how much memory a process is actively using is to use above command. This command is available in Solaris 2.6 and later releases. # /usr/proc/bin/pmap -x 8833 8833: oracleORCL (LOCAL=NO When a Solaris server starts running out of memory it starts scanning for pages and that value shows how quickly it's scanning. If you have a memory-critical application then that must be 0, if it isn't then you need to add more memory. To come back to your original question, this is what you're looking for, it needs to be run as root

The zonememstat command provides an easy-to-read summary of a zone's memory usage, and offers a quick way to verify if a zone is running out of memory. When zonememstat is run without any options from the global zone of a compute node, your results will return memory utilization stats for every zone (including HVM instances) on the server Be default when you create a solaris zone, it will take up all the CPU and memory resources from the global zone. There are ways to limit the memory utilized by zones. The resource capping daemon makes it possible to limit the memory used by zones. Also it is possible to change the memory and swap allocation to a zone online without rebooting it *** Checked for currency and updated for Solaris 11.2 11-March-2015 *** Goal. This document is intended to give hints, where to look for in checking and troubleshooting memory usage. In principle, investigation of memory usage is split in checking usage of kernel memory and user memory The amount of physical memory that a Zone uses cannot be constrained as it stands now, but Sun is working on a feature that will address this issue soon however you can configure capped mem it like this

Total Memory, Used Memory, Free Memory, Buffer Usage, Cache Usage, Swap size and Swap Usage. My question is, what commands are available to show these memory usage figures in a clear and simple way? Bonus points if they're present in the Core install of Solaris. 'sar' doesn't count : Solaris - Memory & Swap Usage Script. May 4, 2013 By Lingeswaran R 4 Comments. How to find the exact memory and swap usage of Solaris server? Solaris uses the memory as /tmp and swap will be calculated along with physical memory. We need to use the right commands to figure out the utilization of both. top is one if the best monitoring. Memory usage, free and used, using sar, top and vmstat in Solaris zone/container Hi all, I have a server running an Oracle database that is part of a Solaris M5000 container. Presumably this is referred to as a zone within a cluster, not sure if I get the terminology right

In addition to restricting CPU usage in the zone , it is also possible to restrict memory usage. This is done via the capped-memory resource. The different Oracle Solaris Zones types use this resource in a different way. In default and Oracle Solaris 10 zones, the usage of physical memory is restricted to the amount specified in th I am sure many of the Solaris administrators will break their head in an order to find Solaris local zones wise resource utilization details on oracle Solaris 10. Because there is no simple inbuilt tool to find these details in Solaris 10 (Apart from prstat -Z).

The simplest way is to run vmstat 1 2 and look at the second row. (The first line of vmstat is a global average of activity since the system booted.) The column headed free shows the amount of free memory in K bytes - and Solaris is nice enough to include the file system cache in this figure, so it is good representation of available memory. The system above has about 150M of free physical. The following chapter takes a deeper look at the Solaris tool prstat(1), the all round utility that helps understand system utilisation. prstat- The Allround Utility One of the most important and widely used utility found in Solaris is prstat (see prstat(1)). prstat gives fast answers to question: How much is my system utilized in terms of CPU and memory

In this example, we are showing the memory utilization of a Zone and restricting the output to 1 Line sar. The sar command, deriving from Solaris and sometimes available on Linux systems as well, is a great tool for looking at memory usage over a long period of time

First you have to have created a zone with memory capping enabled. This would be done during the zonecfg setup: zonecfg:s8-zone-solar97> add capped-memory zonecfg:zone:capped-memory> set physical=50m zonecfg:zone:capped-memory> set swap=100m zonecfg:zone:capped-memory> set locked=30m zonecfg:zone:capped-memory> end Once you zone is configured installed and running, you can view the resources. Solution. To find precious memory installed on the server: If running Solaris 10 and use ZFS file system then need to follow: ZFS Adaptive Replacement Cache (ARC) tends to use up to 75% of the installed physical memory on servers with 4GB or less and up to everything except 1GB of memory on servers with more than 4GB of memory to cache data in a bid to improve performance O ut of M emory Problems on Oracle 10 / Solaris 10. Many kernel parameters have been replaced by so called resource controls in Solaris 10. It is possible to change resource controls using the prctl command. All shared memory and semaphore settings are now handled via resource controls, so any entries regarding shared memory or semaphores (shm & sem) in /etc/system will be ignored

On modern hardware with 32GB memory or more swap space is rarely used for its primary purpose. Bu Solaris has a very elegant idea of linking swap space and /tmp.In other words /tmp in Solaris is memory based filesystem and files in it disappear on reboot. That means that it is important for Solaris administrators to understand the features of the Solaris swap zonecfg:svr01> add capped-memory #limit RAM usage zonecfg:svr01:capped-memory> set physical=4096M zonecfg:svr01:capped-memory> set swap=6G #this must be bigger than physical since it is really address space not swap file usage! zonecfg:svr01:capped-memory> set locked=2G zonecfg:svr01:capped-memory> en Solaris Containers (including Solaris Zones) is an implementation of operating system-level virtualization technology for x86 and SPARC systems, first released publicly in February 2004 in build 51 beta of Solaris 10, and subsequently in the first full release of Solaris 10, 2005.It is present in illumos (formerly OpenSolaris) distributions, such as OpenIndiana, SmartOS and OmniOS, as well as.

It is also possible to restrict the physical memory usage by a process, or by all processes owned by a user. This can be done either in a local zone or in a global zone on Solaris 10 and later Memory caps are enforced by the rcapd daemon, which is a userland process that periodically checks process memory usage, and takes action when a process has exceeded it's alloted amount of memory. To use memory caps on a server or inside a zone, the rcapadm utility needs to be run with the -E (enable memory caps) option to enable memory.

I needed to try and work out what was using the memory on one of my Solaris 10 boxes under test. Check that no-one has created any large files under /tmp. By default on Solaris /tmp is mounted on swap, so any large files created in that directory will consume memory/swap until removed. Use prsta Alarm on high non-global zone memory usage We use a lot of Solaris non-global zones for various reasons.

Different Ways to Check Memory Usage on Solaris Server

  1. I just want to know what's the difference between capped.memory and zone.max-shm-memory when it comes to limit the zones access to the available RAM memory in the global zone. According to here Solaris 10 8/07: Physical Memory Control and the capped-memory Resource The capped-memory resource sets limits for physical, swap, and locked memory
  2. There is a rare sitation that prohibits you to boot or reboot a Kernel Zone. In order to happen, you need to have a massively loaded system and a lot is going on on your system. The problem is, that you don't have enough memory in a way the Solaris Kernel Zones can use. Furthermore: You may remember that the documentation suggests to set the user_reserve_hint_pct parameter in order to ensure.

Plus, the Solaris Fair-Share Scheduler helps ensure that CPU power is not wasted because processing resources are only constrained once the system reaches 100 percent utilization. When it comes to RAM, Solaris Zones share the amount of physical memory available on the system. The amount of physical memory that a Zone uses cannot be constrained. That's Solaris Zones, a method of dividing up a host server's resources among many applications each in its own software partition, known as a container or zone. For example, a zone would assign an application a share of memory, CPU, network bandwidth, and access to the operating system Checking Memory Usage in Linux using the GUI.

Fixed an issue where CDM on Solaris servers does not respect zfs use of memory cache. Support case 20077062 Fixed an issue with the incorrect CDM Solaris memory usage based on the value that is used for Data Buffer and Cache To see Solaris OS grab all free memory is not true. Solaris does grab some free memory, but to an certain extent. I was hoping you can give some insight as to why free swap space also shrinks with free memory when SGA or db_cache increase. Your explanation is useless to me get_memory_usage() - Display the memory usage in MB. The Sage implementation of top() and get_memory_usage() on Solaris are particularly poor for many reasons. The Sage function 'top()' calls the external command 'top' on Solaris, despite the fact that 'top' has never been part of the Solaris operating system Manny\MS, Your not the only one with this issue, we have 62 Solaris 5.10 (sparc and i386) servers monitored with SCOM 2012 R2 UR6. Only 9 of these report memory information correctly, the others all report 100% utilization, when we know from the OS that is not the case

The used column now says, 4594913 Kbytes. If we deduct the two from each other we get, 129026 Kbytes. This equates to about 129 Mbytes. So, sparse root Solaris zones will take about 129 Mbytes. This is a more or less figure. You can now navigate in the newly created Solaris zones filesystems and list files just like you would a normal system The server's current memory usage is 154MB. The figure of 154 can be derived by the formula: Total Memory - (Free + Buffers + Cached) = current total memory usage 503 - 62 - 104 -181 = 156 (very near to 154) So, the memory utilization for the server would be 154/503*100= 30% Moreover, the usage profile of the resource may be a complex function which depends also of parameters such as time. Solaris 10, by default, would adapt itself dynamically so that all of the running applications have equal access to resources If you have a secondary monitor, you can put task manager on the second screen with the CPU performance graph open.

The ancient Solaris machine I was working with did not have it, so I was forced to find other ways of finding information such as CPU speed and memory size. First you can try prtdiag - it will tell you detailed information about all your CPU's and memory banks Memory Placement; When a process requests memory, the OS delivers one or more memory pages. These pages may be on the same system board as the CPU running the process, on some other system board, or, in the case of distributed memory systems, on another system.

Zones is a software partitioning technology that enables the creation and management of multiple virtualized OS execution environments within a single instance of the Solaris Kernel. Each zone (virtualized environment) appears as a system to the processes, users, and administrators within the zone and is isolated from other zones running within. To enable network monitoring with Solaris Zones, use the following steps: Install the sensor on the Global Zone on the main host. Log on to the Database Security console. Click the Sensors tab, and then click the Properties icon. Click Advanced, add the advanced parameter monitor_zones=1, and then click Save
