One feature that my customers have been asking is the ability to see counters in the Guest OS. This can be achieved with Hyperic in earlier releases of vRealize Operations. In version 6.1, you no longer need to deploy Hyperic server.
You download the agent from the same place you download vRealize Operations. You might be confused with the choice of agents. They are quite straight forward actually:
- There are 2 different agents: Windows and Linux.
- The agents come in 2 flavours: with Java or without Java. The one with embedded Java naturally has to have both the 32 bit and 64 bit options, because there are 32 bit JRE and 64 bit JRE.
Because of the above, you have many combinations. They are actually just the same thing 🙂
The agent is much smaller relative to the Hyperic agent. This is a welcomed news for those who are concern with large agent foot print. If you are curious, this is the directory structure now for the agent without the embedded Java.
I personally prefer to deploy the agent with embedded Java. This takes care the Java compatibility. If I use an external Java, it might be updated without me knowing it. That can create some fun troubleshooting activity in data center. It reminds me of the infamous line “Write Once. Test and Debug Everywhere”.
I’m using the Windows agent here as an example. It is already an exe file, so you just need to double click to launch. You will get the setup wizard as shown below:
As part of the setup, you will be asked to provide the certificate Thumbprint. You get that from the http:s//Your-vRealize-Ops/Admin URL. In my case, it’s vrealize-ops-6/admin as you can see below.
Once you login, click on the certificate icon on the top right. I highlighted it below with red rectangle. You will get a dialog box, listing 2 thumbprints. Choose the 2nd one, not the the first one. I’ve highlighted the second one in my case. On your vRealize Operations screen, copy that.
Go back to your Agent installation. When you are asked, simply paste it. I’ve shown mine as example below:
Next, provide credential. I simply use the Admin credential.
The rest of the Setup wizard is pretty forward. Logically, it will also ask for your vRealize Operations address. I provided a FQDN name. Be careful what you type. The setup does not validate it.
The entire installation is pretty fast. At the end, the usual completion screen is shown. It offered to open the readme file. Nothing important that you need to do there. So you are done.
You can validate that it is running by going to Windows Service. Do not look for VMware or vRealize. The name is shown below.
Yes, that’s all you need to do. The next thing is to check if it actually sends data to vRealize Operations. Wait for around 5 minutes, and you should see it. Here is mine:
What if it does not? Where do you check?
Go to the Inventory Explorer. From there, expand the EP Ops Adapter Resources Group. In my case, since it is Windows, I expanded Windows. The resource will appear if it’s sending data to vRealize Operations. The Collection State and Collection Status will be both green.
