Activation Prompt or Watermark

When you first start your lab, you may notice a watermark on the desktop indicatingthat Windows is not activated.

One of the major benefits of virtualization is that virtual machines can be moved andrun on any platform. The Hands-on Labs utilizes this benefit and we are able to run thelabs out of multiple datacenters. However, these datacenters may not have identicalprocessors, which triggers a Microsoft activation check through the Internet.

Rest assured, VMware and the Hands-on Labs are in full compliance with Microsoftlicensing requirements. The lab that you are using is a self-contained pod and does nothave full access to the Internet, which is required for Windows to verify the activation.Without full access to the Internet, this automated process fails and you see this

watermark.

This cosmetic issue has no effect on your lab.

Look at the lower right portion of the screen

HOL-2101-05-CMP


Please check to see that your lab is finished all the startup routines and is ready for youto start. If you see anything other than "Ready", please wait a few minutes. If after 5minutes your lab has not changed to "Ready", please ask for assistance.

The troubleshooting workbench provides potential pieces of evidence of a problemwithin a specific scope and time range. The Selected Scope control on the left of theTroubleshooting Workbench page allows you to vary the scope, such as selecting onlythe object that you are investigating, or increasing the scope to include severalupstream and downstream relationships.

1. Click the + to increase the scope.2. Click the All Objects dropdown and observe the different types of objects you

can choose for the scope.

As you increase the scope, additional evidence is presented under Events, PropertyChanges, and Metrics. As you increase the scope, more objects are displayed in theinventory tree. Also as mentioned earlier in the lab, you can use the custom scope tochange the focus of the workbench.

HOL-2101-05-CMP


Increased Scope to Datacenter

1. Notice that the increase in scope has added datacenter events. In this use casethe event "Lost network connectivity on DVPorts" is the same at the host, clusterand datacenter level. Depending on the use case, there will be different eventsoccurring within the environment. The troubleshooting workbench brings all thisinformation to one spot.

HOL-2101-05-CMP


Events, Property Changes and Metrics

There are 3 main areas in the workbench:

1. Events

Displays events, based on a change in the metrics. Events for metrics that havebreached the usual behavior and major events that have occurred within the selectedscope and time are displayed. The cards are based on dynamic thresholds for a metric,which is calculated based on historical and incoming data.

2. Property Changes

Displays important configuration changes that occurred within the selected scope andtime. Both single and multiple property changes are displayed. For multiple propertychanges, you can view the latest and previous changes.

3. Anomalous Metrics

Metrics which have shown drastic changes within the selected scope and time. Ranksthe results based on the degree of change. The most recent anomalous metric based ona time-sliced comparison in the current time range is given the highest weightage.

When you pin a metric, it appears in the Metrics tab of the Troubleshooting Workbench.You can perform further investigation on the metric in the Metrics tab. You can

HOL-2101-05-CMP


IntroductionIn this module, we will use vRealize Operations to monitor vRealize Operations itself.Typically, we use vRealize Operations to ensure our systems are healthy, but we alsoneed to make sure we are taking care of vRealize Operations. We will walk through thebasics of where to look for help and ensure our management stack is healthy andefficient.

HOL-2101-05-CMP


Log in to the vRealize Operations HVMInstanceThis lab environment is running two different instances of vRealize Operations and oneinstance of vRealize Log Insight. We have the different vRealize Operations instances inorder to be able to work through different use cases that have unique requirements. Thelab vRealize Operations instances are as follows:

• Live Instance: Connected to the small running vSphere environment in the lab.There isn't a large inventory of objects in this instance but it allows us to interactwith vCenter Server.

• Historical View Mode (HVM) Instance: Running a time loop of data that wascaptured in the past. This instance has a much larger inventory of objects butsince it is not currently connected to a vCenter Server, we cannot perform anyactions here.

In this lesson we will be using the HVM instance of vRealize Operations.

Using Dashboards to Monitor HealthIn this lesson, we will learn how to use dashboards within vRealize Operations to gainvisibility on vRealize Operations performance, self-health, and troubleshooting. This isthe first step to ensuring that vRealize Operations, our go-to solution for overall ITmonitoring and health, is itself healthy. We will also learn how to create custom alertsbased on a particular metric straight from our dashboard view.

Access All Dashboards

We should now be in the Home screen after logging into the HVM instance. We will nownavigate to view all the Dashboards we have available to use in order to determine theappropriate one to assess vRealize Operations health.

1. Click on the button to minimize the side navigation bar at the top-left corner2. Click on Dashboards

HOL-2101-05-CMP


Find Self Performance Details Dashboard

Now we want to determine which dashboard we want to use from the inventory we haveavailable. We want to narrow down our search to focus on dashboards related tovRealize Operations.

1. Click on DASHBOARDS in blue to expand the dashboards inventory list2. Type 'operations' in the Search for a dashboard filter3. Click on vRealize Operations to view all dashboards related to vRealize

Operations4. Click on Self Performance Details

Monitor vRealize Operations Performance

The Self Performing Details dashboard has several views into performance metrics ofyour vRealize Operations node. We will walk through some metrics that are worthhighlighting within this dashboard.

HOL-2101-05-CMP


NOTE: The resolution may not render everything properly and as displayed in the image.You may have to scroll for a while to see all the widgets displayed.

1. Verify CPU usage, memory used, memory remaining, and other high-level metrics2. Verify utilization for disk partitions associated with the vRealize Operations nodes

View CPU and Memory Metrics

We will now verify historical trends of CPU and memory for several components of thevRealize Operations node. The orange data points that appear on the individual chartsrepresent the minimum and maximum values of the respective metric. We will thenexplore the Analytics CPU chart further.

1. Scroll down to the CPU/Memory view2. Double-click on any area within the Analytics CPU line chart

Explore CPU Trends and Anomalies

We can now more clearly see the historical CPU trend for vRealize Operations Analytics.Within this view, we can get more details on Analytics CPU by narrowing down the datato a particular date range and by adding trendlines and anomalies. Let's explore whatwe can do to customize our view of this metric.

HOL-2101-05-CMP


1. Click on the Anomalies button to see what is flagged as abnormal givenhistorical trends

2. Ensure the Zoom the view button is pressed3. With your mouse, highlight a portion of the graph by leaving the mouse clicked

for a range of the data, which will adjust the graph to show you just the period oftime you have highlighted.

4. Click on the Calendar icon drop-down to change the range of time of data beingshown, from within the last hour to within the last year. Feel free to play aroundwith the different date ranges in this view.

After going through the steps above, we notice that there are no anomalies flagged byvRealize Operations. Although the chart may suggest that CPU spiked abnormally,vRealize Operations determines whether that CPU change is normal based on how andwhen CPU has behaved in the past in order to reduce false positive flags.

Create Custom Alerts from Dashboard

What if we want to know when CPU (or any other resource/metric) has reached a certainthreshold, even though it is not flagged as an anomaly? We can create a custom alert!Let's walk through how we can create our own alert right from the chart we are viewing.

1. Click on the three-lined icon on the top-right part of the chart2. Click on Create an Alert Definition

HOL-2101-05-CMP


Create Custom Alert

Troubleshooting vSANIn this lesson, we will learn how to use the Troubleshooting vSAN dashboard to assessand address vSAN health and performance.

Troubleshoot vSAN

We can access the Troubleshoot vSAN dashboard either via the Home menu or bysearching through Dashboards. We will access the dashboard directly in the Home page.

1. Under the Troubleshoot pillar, select vSAN

HOL-2101-05-CMP


Alerts on vSAN Clusters

Let's say that we are seeing performance degradation on one of our clusters. Let's seewhat alerts have been triggered on this cluster to start deciphering the issue.

1. Hide the side navigation menu2. Select vSAN Cluster(Host Licensing Cluster 01) to filter by that cluster3. Select VMKernel NIC is experiencing high number of dropped packets

from the alerts widget

NOTE: Depending on the zoom settigs on your Chrome browser window, the widgetsmay appear in different parts of the screen/dashboard. You may need to scroll down/upto see the appropriate widgets.

Details on Alert

We can now see how many times this alert has been triggered on objects related to thevSAN Cluster we had selected. Let's find out more details on one of these alerts.

1. Select View Details for alert triggered on 'sc2-vesxi-linux-02.cmbu.local'

HOL-2101-05-CMP


See Recommended Actions

We can see all symptoms on the host that triggered the alert and recommendations tofix the issue. You can also take action on the recommendation if you so desire.

1. Verify the Recommendation2. Select Actions from the Alert menu

From this menu, we will see all available actions for that specific alert. You can choose tocancel, suspend, and assign the alert as well as perform the recommended action onthe host directly within the vSphere Web Client. Taking action on the alert is out of scopefor this module. Let's go back to the Troubleshoot vSAN dashboard where we left off.

Take Action on Alerts

HOL-2101-05-CMP


1. Expand the side navigation menu2. Select BACK

Determining Root of Health Issues

When we realize there is an issue with a specific object, it is often hard to determinewhat exactly is causing the issue. Is the object itself? Is it an issue with a related object?When trying to figure this out, we also often get a lot of push-back by different teamswho claim their resources are healthy.

For the remaining portion of this lesson, we will immerse ourselves in the scenariowhere different teams are banging on our door because they can't access the resourcesthey need. There is no consensus among infrastructure teams on what is causing theissue. We will now learn how to get to the bottom of health issues within our vSANclusters in order to speed up the troubleshooting process and remove the guesswork.We will also learn how to easily share our insights with these teams. Let's begin byexploring the health of our vSAN cluster's relatives.

vSAN Cluster and Relative Health

1. Hide the side navigation menu

HOL-2101-05-CMP


2. Note that the vSAN Cluster object is healthy as it has no alerts3. Mouse over sc2-vesxi-linux-02.cmbu.local and note that it is the host that was

associated with the alert we just explored

The red badges on the relatives signal a critical alert with that particular object. Theyellow badge signals a less critical alert. This diagram helps us determine which objectswe need to tackle first to avoid associated issues with our vSAN cluster.

Other Visibility in Troubleshoot vSAN Dashboard

The Troubleshoot vSAN dashboard has several views into potential issues on yourstorage environment. Each view helps answer a lot of the questions that we would askourselves when troubleshooting vSAN. Other components we can view within thisdashboard include I/O read and write latency, CPU and memory demands from hosts,disk space utilization, network utilization, disk throughput, cache, disk group capacity,disk group usage balance, capacity disk latency, packet drops, and congestion.

You may browse through the different views within the dashboard to get a betterunderstanding of how the data is visualized. Since these are all meant for viewing, wewill not be showing you any further steps on this dashboard.

Sharing the Dashboard

When there is no consensus among infrastructure teams on the root of an issue, thebest way to clarify confusion is to show where the issue lies with data. Sharing adashboard is extremely useful when you want to collaborate with different teams as youtroubleshoot issues or monitor performance. In vRealize Operations, you can share adashboard either through a live link or by taking a static snapshot of your custom viewat the time of capture.

We will now walk through how to share a live dashboard. Further along in this module,we will walk through how to create a snapshot of a specific view that you can share withothers.

Start Sharing Live Dashboard

1. Select the three-dotted diagram on the top-right corner

HOL-2101-05-CMP


Share Live URL

1. Ensure URL is selected2. Click on the Expiry drop-down3. Click on 3 Months4. Click on COPY LINK5. Click X to exit

Choosing these settings will allow people with this specific URL to access the dashboardonly for 3 months after the link is created. Therefore, there is flexibility in how long wewant shared dashboards to be accessed by team members.

Open New Incognito Window

1. Click on the three vertical dots on the top-right corner of the Chrome window2. Select New incognito window

HOL-2101-05-CMP

Customize Cost DriversIn this lesson, we will learn how to modify cost drivers in order to get accurate costingdata and reports based on our own hyperconverged infrastructure costs in vRealizeOperations.

Customize Cost Drivers

When going through the planning scenarios, a lot of people ask: "where do these costscome from"? The answer is that it comes from what are called cost drivers. vRealizeOperations has cost drivers pre-defined for compute, storage, and networkingcomponents based on industry-based averages; however, you can also update the costdrivers to match your actual costs for that hardware.

ConclusionIn this module, we learned how to use vRealize Operations to gain visibility into everyvSAN cluster in your environment in order to monitor and troubleshoot all aspects of ourvSAN clusters. We used the vSAN Capacity Overview dashboard and the TroubleshootvSAN dashboard. We also discussed how to run modeling scenarios to determinecapacity implications and costs associated with growing and shrinking ourhyperconverged environment. To have more accurate cost data available, we learnedhow to add our actual costs for our hyperconverged infrastructure, which feed into alldashboards within vRealize Operations.
