vFoglight 6.6.1 Capacity Management

Yes, you can do what you want.  The very best part of Foglight is that you can do damn near anything.

Here's one option.

We have a custom row-oriented table which our capacity allocation folks use, which displays all of the clusters, and shows various capacity measures like cpu utilization %, vRAM utilization %, non-local disk free space, etc.  23 columns in all. 

It uses custom functions to calculate cluster type, cluster full status, VMs remaining to fill ( based on the average size VM already deployed), vRAM available for expansion ( a different calc than VMs to fill, since it only takes the vRAM into account), disk status, etc.  IP ranges are included, based on the IP addresses of VMs already deployed, so that the user can check the IP of the new VM to make sure it will fit on the IP ranges available on the cluster.

Our rules are a bit convoluted, and yours are certainly different, but this is definately possible.  And once you have the calculations, you can use the same functions in alerts.

So, does this help you get an idea of where you can go with this?

Thank you John for your quick reply!

Yes this would help us to get what we are looking for. Can you guide me to get our own table and those functions setup?

Thank you

Alex

First, we need to know what rules you want to use.

Let's start with vRAM available for expansion of existing VMs.

How this is calculated depends on:

• How much RAM are you willing to allocate to vRAM. 
  Given that you pay licensing on vRAM Granted, not used, in general the amount of vRAM you are willing to grant on a cluster is tied in some fashion to how much you have licensed, and in few cases would you want to over-provision your RAM, at least in production.  This influences the next item.
• How much RAM are you willing to allow to be utilized?
  ESX Hosts don't like to run with 100% utilized, and going over 100% = ESX swapping, a very bad thing.  We limit a cluster to 70% RAM utilized, so when some VMs need more, they don't push the hosts over 100%. The more you grant, the higher the % utilized goes, in general.

Hi John,

As far as setting up values, we know what will be our rules, but I meant showing where to go and what to create in vFoglight to get a capacity planning table like yours.

As of right now, all of our cluster are running under 65% memory utilization, and licensing/vRam is not an issue as we are using Enterprise Plus. And we are far from overprovisioning our RAM as we keep a really conservative approch to our Virtual Infrastructure (12 ESX/Cluster, running a max of 12 VM per host). It keeps the management happy and our environment is really stable. We are running ESX host with 144GB of RAM.

To answer your question, we would like to stay under 80% of RAM utilization for sure.

Thank you

Alex

Ok, in order to use custom functions, you need to actually go down into WCF:

Here's where to start:

http://edocs.quest.com/foglight/564/files/WebComponent_Tutorial.pdf

When you get that done, you'll have the basics to allow us to proceed.  If you can already do what's in Tutorial 2, bonus.

Thank you John,

Tutorial 1, I was familiar with it, as Ive created multiple dashboard using drag/drop of views and table and template.

Tutorial 2, was new to me.

I think i'm ready to create the table

Alex

Ok, so now, create a table displaying 1 row per VMWCluster, with the standard columns you want to be displayed. 

first, create this query:

List of all Clusters

Select objects of type VMware Cluster from the "(Default)" datasource (of type foglight-5)

    from Root of (foglight-5:default)/VMWModel/virtualCenters/clusterCollection/clusters

Then, build your table. This is what I have as the configuration on my table:

When that's done, we'll work on the custom functions.

Correct, I'll add the renderers to this thread etc. but just now, my basement's flooding, so it may not be until tomorrow.

Also, I've found a bug in my table, going to fix that as well.

Good Morning John,

I have create the table, I didn't create the functions yet.

There are couples things I want to ask you, how do you set the static time frame to 7 days ?

Also, it seems that I'm missing some of the renderer that you use, when it comes to scaling and units. Did you create your own?

Thank you

Alex

When you create a WCF table you can define the timerange statically or allow for it to change.  Also the renders he is using are several he created himself and some are from the vBundle, the functions are his own it looks like.

I'd love to see your functions as well.  It could be something we could turn into a community cartridge and share with everyone.

Hi John,

I hope all is well with your basement.

I was wondering if you had more time to help us out with the report.

Thank you

Alex
