Ignoring vROPS alarms for memory stress?

September 16, 2016, 6:59 am

Hey all,

 

I am still having difficulties understanding the metrics active memory in vCenter and memory demand in vROPS and how they relate to the metrics from inside the guest OS:

 

In my understanding, active memory tries to sample the actual memory usage of the VM on the ESXi level (see: Understanding vSphere Active Memory - VMware vSphere Blog). Memory demand in vROPS is derived from this metric with some RAM added for the OS (source: Iwan Rahabok´s great book: VMware Performance and Capacity Management - Second Edition).


Also he is saying that RAM should be monitored on the guest OS level (see: How to monitor Windows RAM usage with vRealize Operations 6.1), so this is what we are doing with an Icinga agent inside the guest OS.


The VM is a Windows backup VM with 16 GB RAM who is doing a full backup at Friday night:


For this VM vROPS tells me to extend RAM to 17,34 GB because of memory stress:



And now the same timeframe for this VM from inside the guest OS through the monitoring agent:



As you can see the maximum value of memory used from inside the guest OS is approx. 9 GB.

 

So my question is can I ignore the alerts from vROPS regarding memory stress and where is the big difference coming from?

 

Does the guest OS maybe read from the page cache of Windows and this is reflected in vROPS but not counted as used memory inside the guest OS?

 

And if I lower the RAM for this VM will the backups run a lot slower because of the missing page cache?

 

For any insights I would be really grateful!

 

Thanks and regards,

ESXi 5.5 show modules loading during boot

Hi all,

 

I may be wrong but I'm sure I've hit some key combo during boot to show the various modules loading during ESXi boot (rather than the normal boot screen) in order to troubleshoot issues. I've done some net searches and can't find anything about this.

 

What I'm trying to show is all the modules being loaded and their status (similar to what you get in Linux)

 

Have I been dreaming this?

 

Cheers,

How to remotely connect to passthrough graphic card?

July 28, 2013, 11:31 pm

I want to setup a workstation-class virtual machine with passthroughed workstation graphic. This is what I'm using:

 

ESXi 5.1 Update 1 (Build 1065491)

Virtual Machine Version: vmx-9

Virtual Machine OS: Windows 7 x64 with Service Pack 1

 

I assigned a workstation-class graphic card (FirePro S10000) to this VM as a passthrough device. In the VM it's correctly recognized and I can successfully install latest AMD FirePro graphic driver without any problem.

VMWare Tools and VMWare View Agent 5.2.0 are also installed on the VM; VM is registered to my connection server.


Basically I followed this article: http://www.vmware.com/files/pdf/techpaper/vmware-horizon-view-graphics-acceleration-deployment.pdf

On page 19, it mentioned Proprietary NVIDIA Capture APIs should be enabled; I ran this command on my VM but seems it supports NVIDIA GPU only.


I tried two ways to connect to the VM

  1. From a PC (using VMWare Viewer 5.3.0, PCoIP protocol and full screen)
  2. From a PCoIP Zero Client (Dell Wyse P45)

Both ways can connect to the VM. However, only the virtual GPU can be used.

I also tested FirePro V4900 (previous generation AMD workstation graphic card); the result is the same.

I guest that's because I did not enable the capture APIs for AMD Graphic card; but I have not idea how.

CPU Readiness vs. CPU Ready

Hi team,

 

 

I am trying to make sense of "CPU Ready" (Summation in ms) and "CPU Readiness" (Average in percent).

 

 

I refer to the attached screenshot. If I look at the percent value, I get 1.34% in the latest column for CPU Readiness. However, if I look at CPU Ready it is 1612 milliseconds. Applying the formula:

 

(CPU summation value / (<chart default update interval in seconds> * 1000)) * 100 = CPU ready %

(1612 / (20*1000)) * 100

= 8.06%

 

I am looking for the percentage of time my VMs are waiting for CPU resources.

 

 

Do I take the CPU Readiness value of 1.34%, or the CPU Ready value of 8.06% in this example?

 

 

 

Thanks.

Joe

Using NSX Distrubuted Routers vs Edge Routers

It looks like vCloud 8.10 only creates Edge services gateways (ESGs) when setting up routed Org VDC Networks.

 

We would strongly prefer to use the DLR's vs the ESG as its much faster in our environment as most of traffic is east-west.

 

Does anyone know if this is possible or is it on the roadmap?

Hi,

 

Could someone suggest how to get all the "In Progress" requests from vRA? I tried to look around API explorer but couldn't find any existing workflow/action that does this.

May be we can filter out based upon the Server.FindAllForType() and then filter out by state such as either "In Progress" or "Successful".  Please let me know.

 

Thanks.

Hi,

 

I am using Workstation 12.5.

 

I have two screens one with 4K (primary display) and the second one is a regular 720p screen, when I move Workstation to the secondary screen it doesn't adjust to the screen resolution, but everything looks super big - icons, text etc.

Hi All,

 

I am getting connection error during connecting to PostgreSQL db from my vRO "add databse" work flow (located under library\SQL).

 

But I can connect to that PostgreSQL db from vRA appliance through SSH connection. There I am using the database 'vcac' and the user 'postgres'.

Please see below output when connecting via SSH to that vRA apliance.

 

 

 

   Below is the connection parameter passing to the WF input.

Horizon 7 SQL Server Compatiblity

Hi All,

 

I'm trying to determine whether or not my SQL 2008 Standard (R2 SP2) x64 instance would be compatible with a new Horizon 7 installation.

 

On the interop compatibility list (VMware Product Interoperability Matrixes) it doesn't show that it is compatible with SQL 2008 Standard (R2 SP2), but does show that it is compatible with SQL Express 2008 R2 x64.

 

Does anyone know whether that information is correct? Why would it not be compatible with Standard, but it is with Express?

 

Thanks.

Fix / Ideas for Display Corruption under Windows 10 with Fusion 8.5?

I have Fusion 8.5 on a Retina MacBook 13 and also on a Mac Mini with 2 x 1920 x 1200 monitors.  Parts of the display (generally text) blur with checkerboard patterns on both computers, especially in the Edge Browser.  I particularly affects small text being typed (such as this text) but can also affect pure display text.  In most cases moving the mouse over the text will display it correctly, but for some text, it stays unreadable.  The corrupted screen can be copied using Windows Screen Print and the corrupted image shows..

 

It has become a lot worse on my MacBook since I changed the resolution for Windows to be Retina - making me think it may be graphics memory or similar?

 

Anyone with ideas / similar experience or fixes would be much appreciated.

It was initially working fine and I was able to provision the VMs successfully. However, this error came after the Infra team renamed the clusters in the vCenter.

I am not sure if this error is related to vCenter changes?

 

From the vCenter, I can see that the VM has been provisioned (cloned) successfully. However, it is not able to POWER ON.

Error from vCenter:

Failures during upgrade openstack 2.5 to 3.0

October 12, 2016, 7:47 am

Hi,

 

We are having some issues with upgrading vio version 2.5 to 3.0.

 

1) When we install the patch with the command: viopatch install -p vio-upgrade-3.0 -v 3.0.0.4345506 it fails on the installation of 3 python libraries:

installing patch vio-upgrade-3.0 version 3.0.0.4345506

patch-install failed on the following nodes: ['localhost'].

 

We can workaround this issue by overwriting the file /opt/vmware/vio/cli/requirements.txt constantly via a while-true loop.

We delete te following lines from this file:

 

python-neutronclient

python-openstackclient

oslo.vmware

 

On all three python libraries we get the error in /var/log/viocli/viocli.log: Could not find a version that satisfies the requirement pbr>=1.6

 

It is a nasty workaround but the only way to continue.

 

2) When we finally start to upgrade en install a new 3.0 environment the upgrade fails on migrating data with the following error in the ansible.log on the OMS:

 

stdout: error: There are still 90 unmigrated flavor records. Migration cannot continue until all instance flavor records have been migrated to the new format. Please run ' nova-manage db migrate_flavor_data' first.

 

We do a rollback and run the command, with the root user, nova-manage db migrate_flavor_data on one of the controllers. This fails because it is missing a root.key file in /etc/fernet. I cannot run the command with the nova user because this user doesn't have a shell in /etc/passwd. We copied the nova.key file in /etc/fernet to root.key and runs the command nova-manage db migrate_flavor_data again with succes: 6 instances matched query, 6 completed.

 

We start the migrate all over again and it fails: stdout: error: There are still 84 unmigrated flavor records. Migration cannot continue until all instance flavor records have been migrated to the new format. Please run ' nova-manage db migrate_flavor_data' first. This is exactly 6 less then before.

 

Does anybody have an idea?

We upgrade all the way from vio version 1.0.0, maybe there is some old stuff/data bothering us?!

vSphere 6 Max Lun ID

October 14, 2016, 12:22 am

Has anyone tried adding devices with LUN ID's greater that 255 in vSphere 6?

 

Even though the configuration maximum doc clearly states that the limit has been increased to 1023 under FC, in our environment any devices > 255 are not seen.

 

We have not reached the LUN limit of 256 or total no of path limit of 1024. We only have about 30 or so devices presented. We are using Cisco UCS FCoE VIC adapters. Array type is XIO.

 

Now I have logged a call with VMware and the TSE seems to think it's because we are in fact using FCoE, and somehow that would mean that the old LUN ID limit still applies since it's not explicitly stated under FCoE. In other words if the TSE is correct, then VMware are just assuming that customers would come that that conclusion themselves.

 

There is no supporting documentation or KB's about this that VMware support can provide me with, so I am sceptical.

 

Why would FCoE still have a limit of 255 and FC not? FCoE is nothing but FC packaged in Ethernet. Technically this strikes me as illogical.

 

Any views on this appreciated.

Can't get USB devices working, ESXI 6, Skylake H170 board

HI,

 

I'm trying to setup a bunch of virtualised machines, one being a Windows instance that ideally I'd pass through a graphics card, webcam and keyboard to use as a Skype setup to my TV. I bought a skylake based build, on a gigabyte H170 ITX board, and got the video passed through easily. Problem is now USB, from the sounds of reading other posts, I'd have better chance of the keyboard/mouse HID and webcam working if a whole USB device was passed through. But, I only see one in the hardware list, Intel Sunrise Point-H USB 3.0 Controller ( 8086:a12f). That showed as not capable of passthrough, so I tried adding it to the passthru.map file, as:

8086  a12f  d3d0 true

 

But, now it appears still greyed out as disabled.

 

I've only got one pci slot as its an ITX board, and I want to keep the external graphics card in there really. Otherwise I'd try adding an another controller.

 

Any suggestions?

 

Thanks alot!
