Starting 2016 with a bang – #vROps Webinar Series
These will consist of a set of live webcasts on different topics around vRealize Operations Manager open to public to attend live or view the recorded sessions later.
Personally I am delighted to get the chance to work with Sunny Dua on this new project. Sunny is a well known and respected Senior Consultant at VMware and can be found often on twitter @Sunny_Dua. If you have used vCOPs or vROps then its very likely you will have come across his name and his blog (http://vxpresss.blogspot.co.uk/) on top of all of that he is also a member of the VMware CTO Ambassador program.
We thought that we need to uncover some great use cases which we have been delivering for customers and share them with anyone who is interested in learning about vROps. Let me list down the basic rules of this series so that you can hook on to this and can learn more about vROps.
A series of webcasts on vRealize Operations Manager 6.x, helping you learn about anything and everything about the solution. Some of the examples include, vROps Policies, Alert Definitions, Automated Action Framework, integration to third party etc. This would include power point and live demonstrations. The session would range anywhere between 60 to 90 minutes.
VCE Vision, vCOPs to vROps migration
As vROps is still fairly new in comparative terms to other products like vCOPs and VCE Vision, when planning migrations from vCOPs to vROps it is naturally important to check compatibility and what is required for a successful migration.
If you are doing a greenfield deployment of vROps there is nothing to be concerned about, you simply need the VCE Vision appliance running version 2.6.1-2.6.5 and have the latest Management Pack installed on your vROps cluster.
However! what I have encountered when you wish to migrate, things are well, not so great.
Even after a successful and painless upgrade of the VCE Vision appliance, when attempting a migration from vCOPs to vROps a few things occur.
First of all, if you use the supported Vision management pack for vROps it does not detect that the old and the new are alike so a migration cannot occur. I then decided to try the unsupported older management pack which gave me the magical green tick. Sadly after the migration it was very evident the only thing that did get migrated to the unsupported management pack adaptor was the connection settings. No historical data was migrated even after several unsuccessful attempts using various combinations of what I had already been through it was clear something was not right.
So here comes the bad news.
After speaking to VCE and then being passed on to VMware it would seem for now a migration simply is not possible.
“VCE Vision MP is not on the compatibility list of adapters that support the migration process. Due to the lack of compatibility, this is likely why we will be unable to import the historical data from vCOps to vROps for this adapter.”
So that’s it then, for now until it is supported, if you plan to migrate from one to the other bear the above in mind and plan accordingly. Whether that be keeping your vCOPs instance running side by side as reference until you are comfortable with the data collected by vROps, holding fire till it is supported or making the jump and binning vCOPs wholesale.
vROps – first look – part 1 – installation
For several months now we have seen glimpses of vROps by way of limited blog posts and the HOL demo’s so it was great to see it finally released.
So what is it like out of the box?
The first clear change is the move away from 2 VMs in a vAPP and consolidation down to 1 VM which is then easily scalable to more as you require.
The UI has been completely reworked and the install process has also completely changed, so lets take a look.
Deploying from the ovf is very straight forward (you no longer need to worry about IP Pools either!)
Once you have deployed the OVF start up the VM and wait for it to complete its boot process then navigate to the IP you gave vROps to begin the deployment/configuration. As you can/will see below a lot of time has been invested to simplifying the configuration process.
I Opted to do a new a new installation upon which I was then presented with a 5 step process to deploy vROps
vCOPs resources (vCenter Operations Manager)
If you have spent time working with vCOPs you will be aware of the numerous and widespread resources out on the net to help you install and fine tune your deployment. Given there is a lot of content out there that is not always easy to fine immediately I wanted to collate a useful list for my own use and to share with others.
Still a work in progress..

Slow or failed logon to VCSA 5.5 with vCOps in the environment
Recently I encountered this problem in a customer site whereby the logon to VCSA 5.5 would either time out, or take 3-5 minutes to actually log on.
Running a netstat on the VCSA during the attempt to logon showed there was a SYN packet sent to the vCOps appliance on port 443 that never established a connection. Another check was attempting to connect using curl https://<vCOpsIP> –k – this would time out.
Ensuring connectivity to the vCOps appliance over port 443 fixed the logon timeout issue – presumably a the connection attempt holds up the logon process (single threaded?!) which causes a timeout in the logon process.
