Average usage of the CPU with get-stat

• The "cost" of get-stat

  A customer using a (free) ESXi host reports serious performance problems.

  My goal is to see if performance issues are due to memory, CPU, disk, or any other component.

  I've created a PowerCLI script to query the ESXi host to collect conters performance.

  Before starting can use, I assess whether the use of get-stat can aggravate the problerms with the performance of the ESXi host?

  My script should begin every 60 senconds, use the "connect-viserver" cmdlet and then cycle delivering approximately 20 times the cmdlet "get-stat' to get the values such as"cpu.usage.average","mem.usage.average"and so on.

  Can it worsen the performance of the target ESXi host issue?

  Should I before statring to use it?

  Will there be a better strategy to collect performance counters?

  Concerning

  Marius

  Performance in real time on an ESXi node are maintained during +/-1 hour, so I would not ask as often as every 60 seconds.

  The cmdlet Get-Stat imposes some overhead on the ESXi node, then Yes, that this can have an effect on the interpretation of the node ESXi.

  A few other tips to lower to load:

  • use only the counters that you absolutely
  • try to locate the source of the problem with a minimal set of counters, then go down by adding several counters

• Get an error at the end of the output of get-stat

  When I run the following I recover the data, but at the end of the exit, there is a mistake:

  Get-Stat - entity "ESXiHOST" - Stat "disk.totalReadLatency.average".

  This could be the cause of this error? Can I just ignore it?

  It is somewhat related to the issue you reported in metric does not exist, but the documentation says it should

  This output, it seems that you are connected to a node ESXi, not a vCenter or both.

  View the contents of $global: defaultviservers to check.

  On a node ESXi, you get only 20 seconds intervals (for the +/-breaking).

  I suspect that this node ESXi was started, where the limited number of parameters returned.

  If this is not the case, then there is a problem with the PerformanceManager on this node ESXi.

• (Mem.usage.Average & Mem.Active.Average meter with get-stats

  I try to put together a weekly statistics using get-Stats... his works all well but if I use Mem.usage.Average, I have the memory percentage. using mem.active.average would give me the use of memory in KB, I understand.

  However, I get an entry using mem.active.average null.

  On the study, I noticed through the chart options to real a meter (attached document) only the section of memory in time performance?

  The mem.active counter can be added to the other section? or y at - it a config I need to do?

  See you soon

  The metrics are collected for different intervals depend on what you are configuring in

  .

  In this form, you will see the 4 historical intervals and for each, there is a "level of statistics" (being the metric 4, 1 being the least metric).

  You can check what you have there?

  If the level is 1 for all the intervals that could be the reason why you can not get the mem.active meter.

  Note the data in real time, see you in the VI Client comes from the real time hard coded interval (20 seconds) which is collected on the ESX servers themselves and is kept only for a limited period of time.

• CPU/memory of the ESXi host totally access & usage and temp CPU with PowerCLI.

  Dear all,

  I am struggling with the CPU/memory reading of the host completely & information about the use of PowerCLI and the temperature of the CPU is also very useful for me. I used "Get-VMHost-name" to get VMHost to object, but cannot get its properties such as CpuTotalMhz, CpuUsageMhz, MemoryTotalMB, MemoryUsageMB.

  And also do not know which object has temporary information of the CPU. Thank you!

  You probably have a fairly old PowerCLI version (4.0).

  We'll see if the upgrade solves a number of these problems.

• Get some pics of use with get-stat

  In vCOps, you have the concept of the 95th percentile, which allows you to get the 'average of the peaks '.  The idea is that you're taking a set of data points and get the 95th percentile of them for something like the CPU demand MHz for a set of virtual machines.

  Transfer to PowerCLI - in powerCLI rely on database of vCenter data points that were on average through the stacks.

  The problem is the following:

  If I use that data points in the last hour of the statistics 'real-time', my 95th percentile is made with points of data representing the polling intervals of 20 seconds.

  When I move the data points "Last day", then I use averages of these 20 seconds, question marks to get just the data points that represents the average of the 5 minute intervals.  In other words, I've already lost a part of my high and low data points in the update rollup and by 5 minute data are smoothed out now to be an average of the 20 seconds that I had.

  Then spend a week and I have stacks of my data points "last day."  Now my data points are smoothed even further.  Among all of the points of data to the left now, I lost still more ups and downs in my every 5 minutes, and I have only the averages for these intervals of 5 minutes in my 30 minutes of interval data points.

  The point is that the further I go back, the pics more and valleys I lose as rollups toning their stop.  So if I do the calculation 95th percentile, over the period of time, I'm comment less than a true representation of the 95th percentile I don't really have.  Because I work off the coast of data where the peaks and troughs have been rounded more for fewer data points.

  By LucD, who proposed a way to get the 95th percentile:

  https://communities.VMware.com/thread/460129

  I can get a rough estimate of the 95th percentile.  However, it appears (correct me if wrong) that I'll be back a month or two or three months or one year that my 95th percentile will be reduced and a balance budget actual 95th percentile and more a 95th percentile of the average instead of a 95th percentile of actual performance data. and probably further from vCOps make account.

  Any proposed solutions to this problem?  The goal here is to use PowerCLI for model truly what my 'tip' periods look like for an application of VMs CPU when for example, at the end of the month, everyone makes their treatment.

  Although there is no official took in charge methods to extract data from the DB vCOps, it is possible.

  Clinton did a post on this, see informal VMware vCenter Operations Powershell Module

  And of course, there will be a chapter in vCOps in my next book, that I mentioned earlier

• The vib with get-esxcli driver installation

  I am fairly new to PowerShell and PowerCLI, so this may be a simple question, but I looked around and could not find a clear example that shows me what to do. I am running 5.0 GA ESXi and vCenter PowerCLI.

  I want to install a network driver via Powercli in the same way, I would say if I ssh directly to the host, i.e.

  software esxcli vib install - v/vib_file_path/vib_file_name = what in Powercli?

  I created the object, as stated in the docand run down from the tree by using the Get-Member cmdlet, so I know what I need is

  $esxcli.software.vib.install)

  But I do not understand what are the options / call method is required for the command to complete. When I run this without any option, I get usage:

  TypeNameOfValue: VMware.VimAutomation.ViCore.Util10Ps.EsxCliExtensionMethod
  OverloadDefinitions: {vim. EsxCLI.software.vib.install.InstallationResult install (deposit of string [], boolean dryrun, Boolean force, Boolean maintenancemode, boolean noliveinstall, Boolean nosigcheck, string, string [] vibname, string [] viburl proxy)}

  Name: install
  IsInstance: true

  I guess that each of the pairs of hooks is a parameter, so I need give the 3 command options:

  $esxcli.software.vib.install ($1, $2, $3)

  I tried to use a variation of these values, but the error I get is the same:

  PowerCLI C:\ > $test.software.vib.install ($null, "net-IGB - 3.4.23 - 1OEM.500.0.0.406165.x86_64.vib", "/ store /")

  Anyone see what I'm doing wrong?

  I fear there are some more settings, as indicated in the message

  filing of String]

  Boolean dryrun

  Boolean force

  Boolean maintenancemode

  Boolean noliveinstall

  Boolean nosigcheck

  Proxy chain

  String [] vibname

  String [] viburl

  These correspond exactly with the settings described in the ESXCLI command.

  These are all the positional parameters, so if there is a parameter, you do not need, you still need something in this position.

  $esxcli.software.vib.install ($null $true, $false, $true, $true, $false, $null, "net-IGB - 3.4.23 - 1OEM.500.0.0.406165.x86_64.vib", "/ store /")

  This, or something similar, should do the trick.

• Defining the limit of the CPU with c#

  I can't set the CPU limit. Whenever I run the following code what happends is the VM shares get set to low temperature.

  spec.cpuAllocation = new VimApi.ResourceAllocationInfo ();

  spec.cpuAllocation.shares = new VimApi.SharesInfo ();

  spec.cpuAllocation.shares.level.Equals ("custom");

  spec.cpuAllocation.limit.Equals ((long) 1200);

  clientInfo.Connection.Service.ReconfigVM_TaskAsync (vmmor, spec);

  How you set the CPU limit using c#?

  Thanks Jim.

  The snippet above in c# will ask you to set a property more in the specifications, in order to define the limit correctly.

  > spec.cpuAllocation.limitSpecified = true;

  In c#, there are certain properties that require '< propertyName > specified' to 'true '.

  Hope that solves your problem.

• Increase the use of the CPU with nvme or searched ssd ssd...

  My 'record' CPU usage is about 50% on a dual xeon (system more old bridge of sand...) 2 x 8 core 32 thread) when using a consumer 850 samsung ssd as a source and the export of other ssd cache on the hard drive or ssd right also. Yes separate OS and Adobe on SSD. And the cache on another hdd put ssd caching.

  I was wondering if anyone has noticed benefits with source really slamming first CC fast disk... e. g several s searched sata in raid 0 ssd or NVME ssd or ssd pci-e.

  Know and not first love high ghz cores, just trying to find the bottleneck. Made 3d etc and so need a lot of hearts here (soon improve to 16-22 core xeon v4).

  Am also aware that codec has a lot to do with it... h. 264 and cineform (doesn't work does not at the moment) is appalling on the first, while DNxHD seems ok. For some time I've tested DnxHR.

  As a reference, FFMPG with MyFFMPG front end has no problem to use 100% of all cores/threads during the encoding. But of course does not help when editing!

  Will do... but using MyFFMPEG here (front-end GUI for FFMPEG) for some old clips of gopro in protune, h.264 mov DNxHD files hd2 (no DNxHR yet! bummer!), but quite impressive to see all 32 threads pegged at 100%! Yes baby, that's what I'm talking about!

  going to try this once again, important macroblocking, DNxHD standard MyFFMPEG parameters not maxi not rated (hard to say I look on screen uhd)... but then again 8 clips took all of about 5 minutes...!

  Edit even tried with different settings, prores standard on ffmepg profile, once again use at 100%, 8 clips made in about 5 minutes of time... of course could not use pc at all, mouse was the analysis! But good to see the hearts of work!

  Maybe Adobe reeally reaally wants us to be multi-tasking rather than take coffee/beer breaks? Will come back to this topic once I visited configuration (22 carrots x 2!... you know for real work)... and I guess that will have to buy some sort of quad-core i7 for adobe... a piddler machine located in the corner and first... hahaha... what a joke...

• How to use a structure of the event with a state machine

  
  

  I don't know exactly what you're asking, but it sounds as if you want a bunch of script tests and if the user says stop, to immediately stop the current test and abandon others?  I'll assume you know how to clear the table so that it will not abandon the others, so I guess that you have wrong to abandon the current test?  If it is indeed the case, the problem is that you are not able to spread the message of the VI FP main which is the GUI for the sub vi which is the test where the test may or not have a GUI (FP visible) of its own.  Threading is the first thing to come to mind, but it will be may not need the use of events.

  You can do this by passing a refnum of the stop button to the Subvi, where you can then add to wait to the structure of business event.

  I have attached 2 screws, mainvi.vi which is just a loop displays the number * 2 (number of seconds since the race) to be called subvi.vi and then check to see if the button is pressed.  mainvi.VI is in no way a state engine, it's just a simple loop for demonstration purposes.  subvi.VI just waits 2 seconds and leaves, this is a better engine State structured with an init State to start a case of survey to wait events and an exit status to clean.  You can change everything as you wish so that he can do what you want.  You will notice that even if subvi.vi is running, it will automatically end when you press the stop button.

  I hope this helps.

• VM return do not all data with Get-Stat

  Hello

  I'm having a weird problem with a script to output report PowerCLI (attached), there are 3 machines that do fit all the data (the exit is on the attached .txt). This is probably a simple solution, but I don't know how I could reproduce it in my lab and I don't want to mess with the customer's production environment. Maybe some of you guys have concocted with something similar.

  I have powershell v.4, PowerCLI 5.1 running on a windows 7 Pro 64-bit

  Thanks in advance for your ideas.

• Using the SQL with CFQUERY statement variable

  I generate a SQL statement based on user input. I use loops, etc. to create the string of the current statement.
  
  Once the SQL string is created I can display it on the screen and it seems fine.
  
  If I copy the text that appears on the screen and paste it into a CFQUERY, it works very well.
  
  BUT if I try to the variable output directly in the CFQUERY tags set string - it fails... what gives?
  
  Here is the text of the string I am generating in a variable called #insertString #.
  
  INSERT INTO atblProduct (PRODUCTTITLE, RELATEDPRODUCTS, PARTCODENAME, DISPLAY, PRODFAMILYID, DETAILEDDESCRIPTION, overview, APPLICATION type, SPECIALTAB) VALUES (' product ', '1,2,3', ' Code Name', 1, 1, 'Detailed Description', 'Preview', 1, 1)
  
  in the code below, you will see how I try to run this sql using the variable in a CFQUERY tag. Do I need to use a CF function to ensure it is passed verbatim to the SQL engine?
  
  < CFQUERY datasource = "mydb" >
  #insertString #.
  < / CFQUERY >

  Try the function PreserveSingleQuotes.
