Overview of services and applications that send data to VMware Aria Operations for Applications (formerly known as Tanzu Observability by Wavefront).

As part of troubleshooting an application, you need an overview of the services and applications that send data to Operations for Applications. Use the table view or grid view to understand the health of each service, and troubleshoot when your applications or services run into issues.

Table View Features

View the list of applications and services. You can see the Request, Error, and Duration (RED) metrics at a glance and sort the data.

To load the table view:

  1. Log in to your service instance.
  2. From the toolbar, select Applications > Application Status and click the Table View icon ( icon to click to get the table view )

the image shows the table view of all the applications that send data to Operations for Applications. It has helpers to show you what to do with each UI section. For example, how to filter applications or services, change the table settings or the legend settings, and how to change back to the application map view or the grid view

Using the table view, you can:

  • Examine the applications and services, or search for a particular application or service by applying filters.
    You can refine your search further by applying one or more filters, such as the cluster, shard, or span.kind.
  • Click the name of a service to drill down to the Service Dashboard.
  • In the View column, click Service Map to see how a specific service communicates with the other services in the application.
  • Sort data:
    • Sort by application and service names.
    • Sort by cluster names.
  • Create smart alerts that filter noise and capture true anomalies by clicking the ellipsis icon and selecting Create Alert. See Create an alert.
  • View the alerts that fire for a service by clicking the ellipsis icon and selecting View Alerts. The number of alerts that fire for the service are shown in the Alerts column.
  • Inspect the Apdex score and RED metrics to obtain a status summary of a service.
    Table Data Description
    Apdex Shows you how the response time of a service compares to the predefined response time threshold.
    Apdex Threshold The threshold Apdex threshold of the service. The default threshold value is set to 100ms, and only Super Admins or users who have the Applications permission can configure the threshold (T).
    Request Rate The request rate of the service.
    Error % The percentage of the service's spans that contain errors.
    Duration (P95) The span duration at the 95th percentile across the service.

Grid View Features

When you select an application, you get an overview of its services.

To load the grid view:

  1. Log in to your service instance.
  2. From the toolbar, select Applications > Application Status and click the Grid View icon ( icon to click to get the table view )

Shows how the offline traces look once you upload the JSOn file that has the imported trace details.

On the page for a particular application, you can:

  • Examine the services in the application, or search for a particular service by applying filters.
  • Inspect RED metrics to obtain a status summary for a service:
    • The request rate of the service.
    • The percentage of the service’s spans that contain errors.
    • The span duration at the 95th percentile across the service.
  • See how s specific service communicates with the other services in the application by clicking Actions > View Service Map.
  • Create smart alerts that filter noise and capture true anomalies by clicking Actions > Create Alerts. See Create an alert.
  • View alerts that fire for a service by clicking Actions > View Alerts. The number of alerts firing for the service are shown on the red box next to the service name.
  • Drill down from a service:
    • Explore the dashboard for a service by clicking the name of the service or Actions > Service Dashboard.
    • Explore the traces that originate in a service by clicking View Traces.
  • Get a link and share what you’re seeing right now (NON-LIVE display) with other users by clicking Share.

Update Legend Settings

Update the legend by clicking the Settings icon. These settings can be configured by each user and apply to the table and grid view.

Error Percentage
Update the legend to highlight the data based on the error percentage. Select Error % from the dropdown and customize the values. The values must be in ascending order. 		Shows the settings to update the legend for the error %. You need to select error % from the drop down and then add the values in ascending order.
Duration
Update the legend to highlight the data based on the duration. Select Duration from the dropdown menu and customize the values. The values must be in ascending order and in milliseconds. 		Shows the settings to update the legend for the duration. You need to select duration from the drop down and then add the values in ascending order.
Apdex
Update the legend to highlight the data based on the Apdex score. Select Apdex from the dropdown menu. Only Super Admins or users who have the Applications permission can configure the threshold (T). 		The image shows the setting and the legend setting with apdex selected from the drop down.
Alert Settings
Under Alert Settings, select the severity of the alert you want to see on the table view or grid view. For example, if you select Severe, you see the alerts that have the severity status set to severe marked with a red dot on the application map. 		shows the alert settings that has server, warn, smoke, and info listed. You can select one or more severity state to see alerts on the application map.

Create Alerts

Our smart alerts capture true anomalies and filter noise. You can:

  • Specify one or more alert targets that receive the alert notifications.
  • Create a multi-threshold alert to notify different targets depending on alert severity.
  • View an image of the chart in the alert notification and click a link to see the alert in context.
  • Examine firing alerts in Alert Viewer to get context.

Create an alert from the application status page:

  1. Navigate to the table view, or grid view:
    Table view:
    Click the ellipsis icon and select Create Alert.     		A screenshot of how to click create alert as explained in the step
    Grid view:
    Click Actions and select Create Alert.     		A screenshot of how to click create alert as explained in the step
  2. Configure the alert:
    1. You can set the alert conditions based on your data. For example, let’s create an alert that fires in the:
      • Severe state for the shopping service when the error percentage is greater than 6%
      • Warn state when the error percentage it is greater than 3%. See Create and Manage Alerts for details.
    2. Create an alert target to receive alert notifications for a variety of messaging platforms (email, pager services) and communication channels.
      You can also customize your alert targets to include a link to a service dashboard when the alert fires.
    3. Optionally, use alert tags to organize related alerts into categories.
  3. Click Create Alert.

Once the alert is created, click Alerting > All Alerts and search for the alert you created.

Drill Down to Logs

If you have the Logs permission, you can drill down to logs from the application status page and the Traces Browser.

When you notice that a service on the application map, table view, or grid view has a high error percentage, you can drill down into the related logs.

  • From the Table View
    1. Select the time window of interest.
    2. Click the ellipsis icon for the service.
    3. Select View Logs. A screenshot of a the UI once you click vertical ellipsis on the table view
  • From the Grid View
    1. Select the time window of interest.
    2. In a service tile, click Actions.
    3. Select View Logs. A screenshot of a the UI once you click vertical ellipsis on the grid view

The Logs Browser opens in a new tab with the following configurations:

  • The search time window corresponds to the time window on the Application Status page.
  • The search query contains the corresponding service and application tag filters. The search query and the selected time window in the Logs Browser.
