Access alternatives

  • On the CAS, open Reports ► Explore ► Performance data

  • On the CAS, open the Dashboard and click the Data explorer tile.

  • The Data explorer is also a drilldown destination from other reports such as Web dashboard.

Overview

The Data explorer is an interactive report that was introduced in DC RUM 12.4 to extend the data analysis capabilities of the Data Center Analysis (DCA) report (which is now deprecated). For more information, see Comparing Data Center Analysis to Data Explorer.

Data explorer enables you to:

  • Analyze all measurements available in DC RUM across the delivery chain, including Synthetic, RUM, Citrix, and Network tiers

  • Analyze synthetic or UEM-only applications.

  • Analyze performance data gathered by DC RUM by drilling down from other reports with a wide range of dimension filters.

  • Control which analysis perspectives to show from drill down.

  • Use histograms for impact analysis.

  • Start analysis from the Search engine.

Analyzing data with Data explorer

Typical use procedure:

  1. Open Data explorer.
    CAS ► Reports ► Explore ► Performance data

  2. In the Applications section, select an application (click the application name) to focus the Data explorer on the selected application. That will add a filter such as:
  3. In the Transactions section, select a transaction, if available, to focus the Data explorer on the selected transaction.
    (The Transactions section is displayed only after you select an application in the Applications table.)
    That will add a filter such as:
  4. If there are separate transaction steps listed in the Steps section, you can select a step.
    That will add a filter such as:
  5. Set the view of the next table (default title Tiers) to display tiers, services, or servers.
    Again, the filter will be extended with each step. Keep track of the filter as you build it.
  6. In the Software module performance table, set it to view module performance by services, modules, tasks, or operations.
  7. The content of the Software module performance table (including the available drilldowns) depends on the view you select. Select an operation to review the operation health or to drill down to related reports.
  8. In the area below Software module performance (default: Health), use the Views setting to chart:

    • health - fast operations/transactions, slow operations/transactions, aborted operations, failed operations

    • users - affected, not affected, percentage of affected users

    • operation time - network time, server time, idle time, other

    • availability - failures (TCP), failures (transport), failures (application), availability (total)

    • usage - server volume, client volume, operations/transactions, server volume corridor

    • histograms - hits per operation influence, RTT influence, user connection speed influence

Comparing DCA to Data explorer

If you were a user of Data Center Analysis (DCA) in earlier releases of DC RUM, you may want to compare it to its successor.

The following table maps Data Center Analysis functionality to Data Explorer functionality.

Data Center Analysis (DCA)

Data explorer

Offers you insight into the performance of hardware and software infrastructure that supports the application or its transactions throughout the data center tiers.

Improves upon DCA by offering insight throughout the client, network, and data center tiers.

Microcharts application health, operation time, availability, and usage.

Microcharts are replaced with section tabs over the metric charts, users are extracted to a separate chart/section tab, and there is an additional tab with histograms for impact analysis.

Select an application from the Application list to change the troubleshooting perspective, or choose All Applications to evaluate the entire data center.

Remove filters on application to perform analysis from the perspective of all applications.

Select a transaction and steps (a group of operations across various tiers) from the Transaction/Step list. If you select an application and/or a transaction, it acts as a filter for all data.

Remove filters on transaction or step to perform analysis from the perspective of the whole application.

Select one of the perspectives (Application Health, Operation Time, Availability, or Usage) on the Infrastructure Performance section to evaluate the performance aspect that is most interesting in the current context. This will change the metrics displayed on the charts.

Improves upon DCA by offering user and impact analysis perspectives.

When you click a row in the tier table, it selects the corresponding chart and filters information in the Software Module Performance section.

Similar to DCA.

Hover over the data points on the chart for additional information on supporting metrics.

Click to select.

The chart content is based on the selection of entities in the tiers table. Up to 20 worst performing tiers are selected by default.

The first 25 tiers (ordered according to the sequence number as set in the Business Units configuration) are shown.

Click Expand Expand to show more metrics for the tiers table and less charts.

Use the deprecated "interactive table and charts" DMI plugin (together with FDA and AHS) if you need this functionality.

Click Show options ► Equalize axis to use common scaling on all charts for consistent and accurate analysis of comparable entities (for example, servers in the server farm). This is based on the scale containing the worst data. To return to the original chart settings, click Show options ► Unequalize axis. Server names appear with this adjusted scaling, by default.

Use the Chart settings in DMI to control this.

Double-click in the tiers table to drill down to the dimensions configured for the tiers hierarchy. By default you will drill to Software Services, than Servers.

Select a row and switch the perspective to "services" or "servers".

Click Hierarchy hierarchy for a dimension list. These dimensions establish the drilldown order and starting point. Choose at least one.

Hierarchies are hardcoded:

  • Tiers -> Services -> Servers

  • Services-> Modules-> Tasks-> Operations

  •  

In non-DC tiers, hierarchies are similarly hardcoded. For example:

  • tests -> pages (in APMaaS tiers)

  • published apps -> channels (in Citrix)

The Software Module Performance table displays software-based parts of the infrastructure like services, modules, tasks and operations supporting an application on a certain Tier. The Software Module Performance table typically displays information filtered by the infrastructure component (tier, software service, server) and time period, if they are selected on the chart. By default, the hierarchy of this table starts from the Operations level but can be configured to do otherwise.

This section is replaced with a dedicated tables section for non-DC tiers and is different for almost each tier. The

The Software Module Performance table publishes to the User Performance table. The User Performance table displays the applications that contribute to operation issues and their impact on users.

DC RUM now offers a dedicated User explorer so you can more precisely analyze application performance and availability from the perspective of the end user. See CAS ► Explore ► Users

Special DMI plugins used in Data Center Analysis (as well as Application Health Status, Location Health, and User Health) are deprecated and cannot be used for new reports, but existing reports will continue to function.

If needed, you can download the original Data Center Analysis, Location Health, and User Health report definitions from the APM Community.
