Sunny Dua and Simon Eady events

Sunny Dua and Simon Eady have been doing a monthly webex where they are sharing their knowledge on VMware vRealize Operations. The latest one is coming this Friday, Thursday, 25th August. It’s 1:30 PM – 2:45 PM Singapore time. I know it’s not a good time for certain cities. If you cannot make it, it’s recorded.

I’ll join them in the next session. We are hoping to answer questions like the following. We put some answers in light hearted words as you know it’s a serious question.

We live in an era where society is hypersensitive to people who are not sensitive. In the example above, I use her but I meant her/his/him.

The session aims to help you monitoring performance and capacity. Hopefully, you gain a new perspective, and questions like the following will make sense:

See you next week!

Operationalize SDDC program

This post continues from the Operationalize Your World post. Do read it first so you get the context.

Callum Eade and Kenon Owens run a program called Operationalize Your World. Sunny and I provide the technical content. Many folks, both internal and external, have reviewed the materials along the way in the past several years. I was cleaning up my files and surprised to see decks from early 2011 have the old versions of the slides you’re seeing today.

If you only have 10 minutes, here is a 7-minute introduction to what you get in the 1-day workshop. Thanks Alastair and vBrownbag for inviting us again.

summary

The program is a 1-day workshop. It helps customers operationalize their VMware SDDC environment. The structure is as follows:

agenda

We use a restaurant analogy to raise awareness that your IaaS business should be operated differently. There are 4 main ppt files.

powerpoint

You can find the material hereThey are in editable format (ppt), not in PDF format.

We are giving in PowerPoint as Operations vary widely. Take what’s relevant to you, throw away what’s not, add your custom deck, and make it yours. When you share your deck to your peers or customers, let me know how it goes. I’m keen to hear your journey. It’s a journey because it will take you multiple rounds to enlighten your peers.

The 1-day workshop covers 4 areas in management (Availability, Performance, Capacity and Configuration). We map each area to both Consumer and Provider layers of your IaaS business.

Operationalize Your World: Import Steps

This post continues from the Operationalize Your World. Do read it first to get the context.

Read the whole instruction first, before executing the steps.

Planning

  1. Decide which clusters and datastores are on what Service Tier.
    1. If you are doing IaaS business, you should have at least 2 policies. That’s why I have not thought of a business scenario where you only have 1 policy.
    2. You choose per cluster, not per resource pool. The Policy is applied at cluster level. I do not use Resource Pool. It complicates matters operationally.
    3. If you have no SLA, you have a bigger problem than IaaS monitoring.
    4. You can place VM on Tier 1 Compute and Tier 2 Storage, although that just makes your operations complex. It’s like giving economy class passenger a business class TV & meal.
  2. Define Large VM.
    1. I used large VM as those with >8 vCPU or >24 GB RAM.

Prerequisite

  1. vR Ops Advanced edition or higher. Standard edition does not allow custom dashboard.
  2. vR Ops 6.5
    1. It works with 6.3 or 6.4. Follow the steps here, plus create the groups manually here.
    2. Thanks Sergey Kalugin for pointing out that it does not work with 6.2.x
  3. Hands-on with vR Ops 6.x. I assume you know what you’re doing.
  4. Have an ID with admin privilege. Do not use the built-in Admin account. It creates confusion between OOTB content and what you create.
Download the files here. 

Just unzip the downloaded file. No need to unzip the zipped files inside it, as you can import a zipped file.

Steps (Summary)

The steps can be grouped into 3 parts:

  1. Part 1: Group
    1. Create the group types
    2. Import the groups.
  2. Part 2: Super Metrics and Policies
    • Import the Policy. It’s merely a vehicle to bulk import super metrics.
    • I do not use the policy. No need to enable the policy.
    • Enable the super metrics in your active base policy
  3. Part 3: View & Dashboards
    1. Import the Views
      • Do this prior importing the dashboard as there is dependency
    2. Import the Dashboards.
      • Importing dashboard automatically creates the menu structure
    3. Recreate the XML files
      • They cannot be imported.

Steps (Details)

Read the steps as it has more details than the videos.

Follow the names exactly. They are hardcoded in the dashboards. 
Names are Case Sensitive!
If you do not follow, import will work, but you get hourglass icon.

Part 1: Group

Create these group types:

  • Class of Service
  • VM Types
  • Tenants
  • Multi-tier Applications
  • Single-tier Applications
  • Application Tier

Import the groups.

Part 2: Policy and Metrics

Import the policy. Choose Skip import to ensure nothing is overwritten. You will actually not overwrite anything as the file you import is a dummy policy. All it has is super metrics.

Policy import

It should take around 1-2 minutes. You will get this when done.

Policy import success

The purpose of the policy import is to merely import the super metrics. We have to enable them manually. If you are curious the list of super metrics you are getting, the list looks something like this:

Super Metrics

Once imported, enable the super metrics in your base policy. Yes, you can bulk enable by selecting multiple lines (as shown below). Use the Actions menu to enable them all.

enable super metrics

After you import the Performance SLA super metrics, review their settings. Do adjust the SLA accordingly if you know the performance of your IaaS. If you are running Balance power management, change the CPU SLA to 10, 20, 30 accordingly.

Create 1 policy for each Tier. This has to be based on your active policy, so the inheritance works properly. In the example below, my base policy is called OneCloud Default Policy. Make sure you choose the right one.

You must use the following names for the Policy:

  • Tier 1
  • Tier 2
  • Tier 3

Enable the correct SLA for each tier. In the example below, I’m enabling Tier 2. From the big red number 1, you can see I’m editing a policy named Tier 2. You can see it’s being selected in the background, behind the dialog box.

See the big red number 2: It shows the Performance SLA that should belong to Tier 2. As a result, I only enabled them (see the big red number 3). I do not enable the super metrics for Tier 1 (see the big red number 4).

Correct super metric for each policy

Click Save to end the editing.

For Tier 1, ensure you also enable the super metric specific to Tier 1.

Assign the policy to its associated group. Tier 1 policy should be mapped to Tier 1 group. Below is an example. Use the green plus sign, as I circle it below:

Assign policy to Tier 1

You know you got the policy associated when it appears in the Active Policies. The screenshot below show I’ve activated all 3 Tiers

policy

Do the same steps for Tier 2 (Silver) and Tier 3 (Bronze).

Part 3: View and Dashboard

Import the view, then the dashboard.

view import

The lists shown below is partial. There are >100 in total. I use View widget as they are flexible.

view-list

Import the Dashboards. You can import them in any order. When you are done, it looks something like this.

dashboard

XML Files

Recreate the XML files. They cannot be imported. Luckily, they are optional. You only need this step if the dashboard is not clear to you.

xml

Once imported, take your well deserved coffee break! It you have a large environment, it can take an hour for all the dashboards, super metrics, policies, groups, to be applied. During the process, you may see the known error while trying to open a dashboard. Just wait an hour or so.

When things go wrong

If your dashboard has hourglass icon, likely it’s because a metric or object is missing. The root cause is likely a missing group.

You should not need to do any of these things. But if things go wrong, there are a couple of things you can check. First, ensure each Policy actually applies to the correct object. For example, you can see below that I’ve applied the policy named Tier 2 to a group called Tier 2. Under the Assigned Groups, column, it shows it’s being applied to 1 group and it impacts 302 objects.

Policy objects group

The same goes with super metrics. In the following example, a super metric is being applied to Tier 2 policy. It’s not applied to other policies, as it does not make sense.

Super Metric n policy

If import fail, you will see the error message. Simply rename the duplicate object, then reimport.

import duplicate

You cannot re-import. The reason is the ID remains the same. Delete the existing object, then reimport. It is safe to delete.
