  • Click one or more applications in that list to filter the report by those applications.
  • Click an application again to remove the filter for that application.

Health status walkthrough

If your primary use case of Dynatrace NAM 2018 is to monitor performance of your applications, health status is the starting point for you, in which case you should go to the Health dashboard and work from there through other dashboards and explorers to suit your needs.

One of the goals behind building the Health dashboard was to deliver a report that would replace the Application Health Dashboard (AHS) and Applications dashboard reports to answer the same questions with a single report.

NAM: Health dashboard: Summary

The default landing page (Summary tab) helps to answer key questions about your environment:

  • What is the health distribution among your applications and software services (and how many of them are currently present)?
  • How has health, business impact (number of affected vs unaffected users), and traffic volume in the whole environment changed?
  • How has the number of alerts changed up to the current time?

This dashboards Overview tab offers an alternative view of all your applications, where each application is represented by a tile indicating application health by color.

NAM: Health dashboard: Overview

Healthy applications are green. Less healthy applications are yellow or red and have an indicator for the main reason they are in poor health (primarily slowness or a high number of failures or aborts). This view has been optimized for network operations center (NOC).

Use the menu options in the Application overview section to change the focus of the tiles:

NAM: Health dashboard: Overview: selecting a view

For each application in the report:

  • tiles (the default perspective) shows compact tiles with health expressed as a percentage and a simple graphic indicator of reason for less than optimal health.
  • health shows the recent health history, with special tiles that extend the previous health NOC-style view with charts showing recent health and operation time for each application.
  • operation time plots the operation time breakdown over time for each application.
  • usage shows a usage breakdown over time.
  • availability shows a failures breakdown over time.

In any of these views, you have quick access to further analysis.

You can quickly select one of the applications to show its detailed information, show tiles for transactions defined for this application, or further analyze the current state of this application in one of the explorer reports. For applications affected by slow operations, a dedicated link to the Slow operation cause breakdown report is available. Similarly, when there are failures or aborts, you can quickly jump to the Error explorer to further analyze those failures.

Regardless of whether you choose to show the overview tiles or detailed tiles charting health information over time, the same set of interactions is available.

Details

Select the Details button on an application tile to drill down to the details perspective, where the overview charts are reduced and rendered at the top (just as in the NOC view) and information about your applications is rendered in an interactive table.

At a glance, the table shows you the health, root cause of problems, requests and transaction time breakdowns, affected vs unaffected users, and health of all client and network tiers through which your application is delivered.

You can change the perspective through which you analyze the state of your applications:

  • health focuses on general application health
  • slowdown focuses on reasons for slowdown, including transaction time
  • availability focuses on application availability, including errors
  • network focuses on the network, including loss rate and RTT
  • business impact focuses on business impact, including transaction time and users affected

Transactions

Select the Transactions button on an application tile to show transactions defined for the application.

Expanding rows and drilling down

Depending on which perspective you choose to review your applications, when you select a table row representing one of the applications, the row expands to show more detailed information tailored to the perspective of your choice. In addition to a number of charts showing your application status over time, you can also review the health of transactions defined within each application and the health of the tiers through which your application is delivered.

Hover your pointer over any chart in an expanded row to see details for the selected time and, depending on the perspective and the chart you choose, drill down to explorer reports (for example, Data explorer, Operation explorer, Error explorer, User explorer) and dedicated application dashboards (for example, SAP dashboard, Web dashboard, Database dashboard).

Navigation tips

  • Click on the Applications breadcrumb at the top of a report to go back up from the details level to the applications level.

    NAM: Health dashboard: Details: breadcrumbs

  • Open the quick-access menu at the bottom of the table to switch to explorer reports or to select whether to show or hide currently inactive applications, whether to show only affected applications, and whether to show only those applications that are in a given health state.

  • You can’t save changes to the Health dashboard directly, but you can save an edited copy under a different name.

  • You can select the Health dashboard as a favorite on your NAM Server Favorites tab, in which case the currently selected view is remembered. When you open it from Favorites, it opens to the view (Overview, Details, or Most affected) that was selected when you favorited it.

Show most affected

Select the Show most affected button from the Summary tab (for a general report) or from a the Details page (filtered by the selected application) to display a detailed NOC-style view of the most affected applications.

From here, you can easily assess the health of your apps, the root cause of their problems, and the history of changes in the health, availability, operation time, and usage up to now. Depending on how your apps are delivered, you will also gain access to an overview of key tiers: a Citrix, (worst-performing) Network tiers, and Data center tiers overview for each app. For network tiers, you can chart network performance, loss rate, and RTT changes over time.

  • When rendering network status over time, you can choose which tier to analyze on the time charts.
  • Most affected shows the top 25 most affected applications by default, but you can select applications in the Applications section to focus the report.
  • If you have synthetic tests you would also like to show on the Most affected view, open the report for editing, select the Global parameters tab, locate the Show synthetic tiles row, and change User filter for that row to true.
