vRealize Operations Manager 8 - Custom views and reports

vROps has a number of inbuilt views and reports templates. In this post, I will explain how to create custom views and reports. 

To create a new view: Dashboards - Views - New view

Provide a name and description for the new view. Here, for example, I will create a view that shows datastore write performance stats.


Select List.


Select Datastore as subject and group it by cluster compute resource.


Drag and drop the selected metrics or properties to include in the view.
In the following screenshot, I selected a property "Is Local" and included in the view.


Added another property "Type" to the view.


Similarly, I added some metrics like Write IOPS, Latency and Throughout to the view.
I selected "Maximum" from transformation to get the peak value of the selected metrics.


In the below screenshot, you can see I selected "Maximum" and "Average" transformation for Write IOPS, Latency and Throughput metrics. You can also select the units as per your requirement. Here, I selected "us" for latency and "MBps" for throughput.

Click Save. 


Similarly, I created three custom views that show:
  • "Datastore read performance stats"
  • "Datastore write performance stats" 
  • "Datastore capacity usage"


To create a new report template: Dashboards - Reports - New template


Provide a name and description for the new report template.


From the views and dashboards, find the three custom datastore views that we created earlier, drag and drop them to the right pane as shown below.


Select PDF and CSV.


Select all the layout options if you like to and click Save.


Now the custom report template is created. You can select it and click Run.


Select vSpehre Hosts and Clusters and then select vSphere World and click ok.


The report will run in the background and will be available to download under the "Generated Reports" tab. You can select it and download the PDF or CSV file.


You can even configure a schedule to generate a report and email it or save it to a location automatically based on your requirements. Hope it was useful. Cheers!

vRealize Operations Manager 7.5 - Part4 - High availability

In this post, I will explain the steps to expand an existing vROps installation and enable high availability.

Before making a design/ architecture decision on enabling high availability for vROps I strongly recommend you to go through the below VMware vROps documentation links and understand the functional/ technical implications of it.

  1. About vRealize Operations Manager High Availability
  2. High Availability Considerations
  3. About vRealize Operations Manager Cluster Nodes

Expand an existing installation


Deploy a new vROps appliance. Once the deployment is complete, open the management IP of the appliance in a web browser. This time select expand an existing installation


Click next.

Provide a name for this new node.
Select the node type as "Data".
Provide the IP address or FQDN of the master node and click validate.
Accept the certificate and click next.


Provide admin password and click next.

Note: If you don't know the admin password you can request the vROps admin to provide a shared pass-phrase and can use it.

Click finish.

After this step, you will be redirected automatically to the admin page.


As you can see in the above screenshot, installation is in progress and is waiting to finish the cluster expansion. It may take a few minutes. Once it is complete you can see a button to "Finish adding new node(s)".


Click "Finish adding new node(s)" and click ok.


This will take a few minutes.


Now, you can see that the new data node is online and running. Next step is to enable high availability.  


Enable High Availability


To configure high availability, click "Enable".

Cluster Restart Required: The cluster needs to be restarted in order to configure HA. This may require up to 20 minutes during which vRealize Operations Manager will not be available.

To ensure complete protection the two nodes (Master and Replica) should not share hardware.

Click Ok.
Click "Yes" to continue HA configuration.


This will take a few minutes. The cluster will be taken offline for enabling HA.


After a few minutes, the cluster is back online and HA is enabled. And as you can see in the below screenshot one node is "Master" and the other one is "Master Replica".


vROps also has dashboards that provide you details on the health status of the complete vROps environment, cluster statistics and performance details of vROps itself, etc. Sample screenshot of the "Self Health" dashboard is shown below.  


Hope it was useful. Cheers!

vRealize Operations Manager 7.5 - Part3 - Rightsizing

In this article, I will briefly explain a performance optimization feature in vROps. This feature will help the user/ customer to easily find out a list of oversized and undersized VMs. vROps will provide recommendations on allocating the right amount of resources to the VM. 

Rightsizing



As you can see in the screenshot above, there are 29 VMs that are oversized. And vROps is providing recommendations on the amount of CPU and memory reduction that can be done to optimize performance. Oversizing always have a negative impact on the performance and it is recommended to allocate the right amount of resources to a VM for optimal performance. Let's take an example of one of the VM. 


You can see that the recommendation by vROps is to reduce 8 vCPUs and 15 GB of memory. This recommendation is based on the analytics and forecasting capabilities of vROps. You can click on the VM name and it will show more details regarding the selected VM.


vROps also provides a way to resize the VMs directly from the console. You can select the VMs that you would like to resize, and click "RESIZE VM(S)".



NOTE: The workloads may be interrupted as it may require restart during resizing. 

VMware guidance: CPU Ready time and Co-Stop values per core greater than 5% and 3% respectively could be a performance concern. 

Hope it was useful. Cheers!

vRealize Operations Manager 7.5 - Part2 - Configure vCenter adapter and dashboards overview

In this post, I will explain how to configure the vCenter adapter and will also walk through some of the native dashboards.

Configuring vCenter adapter


  • Login to vROps.
  • Click the Administration tab.
  • Select the vCenter Adapter. 
  • Click the gears icon.



  • Provide necessary details.


  • Test connection.




  • Click save settings and close.
  • Once the above steps are done, in a few seconds you can see "Adapter Status" as Data receiving and "Collection State" as Collecting.  

Note: After configuring the vCenter adapter you should actually wait for few days for all the data to get collected and populated.

Dashboards


This is the place where most of the System administrators/ Operations Engineers spend their time for understanding/ evaluating the operational aspects of their virtual infrastructure, capacity planning, troubleshooting various issues, performance optimizations, etc.  vROps has many pre-canned dashboards that you get out-of-the-box. Below screenshot shows how to select/ navigate multiple dashboards that are available in vROps.


Now, I will just briefly explain some of my favorite dashboards. 

Operations Overview


This dashboard provides data center summary. It provides info about the total number of clusters, hosts, total VMs, running VMs, datastores, etc. This dashboard also has widgets showing details about the top VMs experiencing CPU contention, memory contention, and disk latency.


Utilization Overview


This dashboard provides a summary of the environment based on the selection. In this case, I selected a cluster. It shows the total (CPU/ memory/ storage) capacity of the selected environment, usable capacity, used capacity, remaining capacity, etc. This will be very useful for capacity planning of resources.  

Cluster Utilization


This dashboard shows the CPU, memory, disk IOPS and network usage trends at the cluster level.


Datastore Utilization


This dashboard provides detailed info on datastore usage trends and heatmap based on datastore capacity/ utilization.


Heavy Hitter VMs


This dashboard provides cluster-level CPU, memory, IOPS and network throughput. It also gives a list of VMs which has generated the highest CPU demand, memory demand, highest IOPS and network throughput. This is very useful for identifying the VMs that has the highest resource consumption.
