I just got quite excited about the fact VMware's PowerCLI 5.5r2 release. For me it's the full tag support.

Maintaining a large vSphere environment can be challenging at times and trying to keep a good overview is crucial. Using tags (in the previous vSphere versions you could use 'Custom attributes') can help significantly. Some examples you can put in tags, things like: bladechassis name, slot, link to CMDB, installed by, special usage, etc. etc. I cannot wait to go to work tomorrow and check it out Laughing.

Just got back from my holiday - first thing to check is our VCOPS environment of course (and secondly, start writing these kind of posts Cool). One thing that always attracs my attentions, that 'purple'-alert message in the top-right called the "Admin Alert":

There was a nice question on the VCOPS forum today about having a big screen and rotating through custom dashboards automatically. Custom dashboards is a 'Advanced/Enterprise' feature, and I think you cannot live without them. You can make them switch to other dashboards automatically.

Click 'Dashboards -> Reorder Tabs...'

In the release notes for VCOPS 5.7.1 one of the fixed issues for VIN is:

"vCenter Infrastructure Navigator adapter discovers too many resources
The vCenter Infrastructure Navigator adapter was configured to discover and calculate resources related to obscure open TCP ports. This configuration increased the load on analytics processing as well as on the storage sub-system that stores this data."

I don't know how long this feature has been in the product, however I couldn't find any documentation around it. You can group your dashboards by naming the tab: [group]/[name]. Here is an example:

By default your session times out from the UI (both the vsphere ui as the custom ui) after 30 minutes of inactivity. This can be annoying when you're running a big screen display showing your favorite widgets. Quite a lot of articles excists around this so more than enough resources can be found including an official KB from VMware: KB2015135.

However, I've found VMware replaces the web.xml with the default timeout during .PAK updates (like going from 5.6.0 -> 5.7.0 -> 5.7.1). Now I would not recommend replacing the altered previous web.xml since it can hold new settings. But I'm getting tired of getting into vi, edit two files, on all VCOPS servers and repeat that after every update. So here is a small script which does a 'sed' and replaces whatever value in the session-timeout to '-1'. It creates a backup, replaces the value and restarts the UI interface, both vsphere as custom.

The ability to schedule reports in VCOPS is quite cool. Taken from capacity IQ these reports can be run weekly or monthly on a specific time and day of week allowing you to show the report as CSV (to process inside a spreadsheet) or as a readable PDF document. Once SMTP is configured you're able to send the report to multiple users (you, your manager) using comma (,) or semi-column (;) separated e-mail addresses. Also: you can schedule reports on ANY level on ANY object (World, Folder, Datacenter, Cluster, Host, VM, Datastore), and here, the management of all schedules, can become a mess since there is no overview on where schedules are set.

Here is a little query you can run on the UI vm (this is where CapIQ is running).

I'm quite excited. Just found on the VMware website that VCOPS for Horizon View is GA. Together with this release there is also a new version for VCOPS -> 5.7.0.

One of the cool things with this release is the .pak file usage. No longer you'll need an additional Windows instance (or multiple when having multiple PODs) for passing the data to VCOPS. VCOPS is capable of handling the datastream direct from the broker agents and client agents. Installation is a breeze - just install the .pak file on the /admin part on VCOPS, just like doing the update to VCOPS 5.7.0.

Using Super Metrics in VCOPS is quite common and well documented. There are also nice blog posts (http://www.batchworks.de/using-super-metrics-to-monitor-cpu-ready-part1/ and http://www.virtualclouds.co.za/?p=254). When creating a report or a dashboard, I like to show the metric in percentage. Percentage is nice as you know, since the human mind instantly sees this value as 'wow, that's high or hmm, that's pretty low' since the range is between 0 and 100 most of the time.

VCOPS includes a lot of percentage metrics already. However, if you look at for example CPU Co-stop, System, Idle - they are only available in milliseconds (ms). Now there is a small catch you'll need to take into account which I'll show you in this blog post.

I'm in the process of re-registering my vCenter servers to VCOPS (with another username). Once in a while I have this error message:

Unable to connect to vCenter Server. Details: Failed to get RMI connection. Ensure that vcops service is running and retry the operation. Registration failed for VC : ( vCenter Server address: https://bla-host/sdk, vCenter Server username: bla-user, vCenter Server name: BLA blabla ) RMI interface unavailable

Yesterday I tweeted a picture showing off my Raspberry Pi with bi coloured LEDs (Red and Green). I've always wanted something to put on my desk, with LEDs, checking vCenters and/or ESX(i) hosts. After experimenting with the Arduino, I knew this system would be a stand alone application (requiring something like an external VM, doing the checks, sending the Arduino the status). I wanted a standalone device, as small like the Arduino, capable of checks against vCenter. As you all know, the Raspberry Pi is suitable for that task.

Goals in mind

While having my thoughts run freely, I knew I wanted something:

Last week I got back from holiday, had a wonderful time in France with great weather. Anyway, we're looking into changing one pool with virtual desktops from one vCPU to two vCPUs. Looking a CPU load on every host in the cluster should allow that, but we are very curious what the ready time would be.

Ready time is a VM metric, but we want to know the 'average' on the whole cluster. PowerCLI to the rescue:

I'm writing a Powershell script on getting info from a View environment. One thing I noticed was the amount of time the 'Get-Pool' commandlet takes to finish when using '-pool_id'. Now I know the commandlets are not very well written (it is sooo 1980s to run the commands from a broker), but take a look at this example:

Measure-Command{$poolinfo = Get-Pool -pool_id $PoolName}
Measure-Command{$poolinfo = Get-Pool}

This is just a very little tip for today: fill your blade chassis vertical, instead of horizontal. Here is a little illustration:

On the left we fill a chassis from left to right, top to bottom. On the right we fill the chassis from top to bottom, left to right and for full height blades, we start filling from the right.

No sorry, there is no plug-in for Synology to download patches (would be cool though - anyone?). However, I've been fiddling around with vSphere UMDS and wanted to have the patches downloaded to my Synology NAS box. And through the Synology webservices act as a patch store - AND IT WORKS :-).

Setup is quite easy, running a Windows 2008 machine. Now there are excellent tutorials and manuals available online to install UMDS, so I'm not going to repeat that.

    Hi Aleks, I'm using the 1511. The NAS works fine for ESXi - however, I've only been using NFS (so I didn't try iSCSI yet). As a '

Triggered by @esloof his post on Freesco 0.4.3, I wanted to create such router into a VM, but for version 0.4.4. I also wanted to move it to a virtual disk so I could make an OVF and do multiple deploys. While trying to get this to work after a few hours, I finally found a really fast and reliable method to do it myself in like 10 minutes (and so can you after reading this manual).

What do you need?

- freesco, get it from here (download the ZIP)
- ext2-0.4.4-lewis.pkg get it from here

I was rebuilding my homelab and wanted to create 'sites' using vlans. I am using the HP Procurve 1810G-24 switch (cheap, works great) but I had to fiddle some things out and I got it now. I know other sites have nice tutorials, but this is a quick recap from me.

Setup

I have three vlans right now. Default (1), lab1 (101) and lab2 (102). Click VLANs and the image below should say enough:

Hi all. Today (17-4-2012) William Lam provided a method to prevent HBA drivers to be loaded during installation and upgrades. This makes the removevmhba script obsolete. Since I got asked quite often wetter this would be possible for ESXi, I couldn't answer. However, check out this post, since that would be the current solution right now. I have updated the download description accordingly.
