Advanced Diagnostics on Demand

Applies to NAM 2018

Advanced Diagnostics on Demand (ADoD) offers real-time access to discrete operation details, including load sequence charts. Your primary view of ADoD data is through the Operation details explorer, which (depending on your configuration) shows operation details down to the load, hit, or header level.

ADS and ADoD

Applies to DC RUM 2017

If you used ADS in earlier releases (DC RUM), see Upgrading DC RUM 2017 with ADS for details about moving from ADS to ADoD.

Example ADoD workflow from the Operation explorer

  1. Open the NAM Server dashboard (NAM Server ► Dashboard).
  2. Open the Operation explorer.
  3. Click a software service (for example, HTTPS) for which you want to analyze operations and select Show operations for this software service.
    This will refocus the explorer on operations for the selected software service.
  4. In the Performance details table, click an operation to analyze and select Analyze operation details to continue to the Operation details explorer.
    If this menu option is unavailable, there is no operation detail data to display for the selected operation.
  5. The Operation details explorer lists loads for the selected operation.
  6. When you select one operation load, its details are presented, together with a step chart and details of all hits within this operation load.
  7. The step chart and details table are linked: selecting a hit on one highlights and reveals details in the other.

For more information, see the Operation details explorer help.

Licensing and configuring ADoD

You need a license to use ADoD. See Licensing for information on obtaining licenses.

Applies to DC RUM 2017

If you were an ADS user in DC RUM 2017 and upgraded to Dynatrace NAM 2018, you have an ADoD license already. See Upgrading DC RUM 2017 with ADS for details.

After you have a license, you enable ADoD in software services configuration for the monitored applications.

Example configuration path:

  1. In the NAM Console, open Monitoring ► Software services.
  2. Select the software service and select Actions ► Edit Rule to open the Edit Rule screen.
  3. On the HTTP Options tab, set Data generation for one of the following levels:
    • disabled
    • operation load only
    • operation load and hit details
    • operation load, hit, and header details
  4. On the URL Monitoring tab, you can open a URL definition and make similar settings at the URL level, or choose to inherit the setting from the rule.

ADoD data limitations

The amount of ADoD data stored is determined by the disk storage size on NAM Probes that host the ADoD data and the access speed to those disks. Storing more data means using more disk space on the NAM Probes.

The NAM Probe automatically deletes the oldest data files when the disk is about to become full. As a result, the ADoD data storage period may vary depending the disk storage available and the traffic levels you monitor.

ADoD dimensions and metrics

When defining a custom report in DMI, there are four data views based on Advanced diagnostics on demand:

  • Operation data
    The highest level of ADoD data. In the Operation details explorer, this corresponds to the information in the Operation loads table.
  • Hit-level data
    The middle level of ADoD data. In the Operation details explorer, this corresponds to the information in the Load sequence section.
  • Hit header data
    The lowest level of ADoD data. In the Operation details explorer, this corresponds to the information shown within a single hit in the Load sequence section.
  • Sequence transaction data
    A dedicated data view for operation sequences.

Creating custom reports using ADoD

When creating custom reports using ADoD data, use filters to keep data size manageable:

  • You must set a filter in the report definition to ensure that data size is kept within limits.
  • If too many rows (more than 20,000) of raw data are returned from the ADoD endpoint at the NAM Probe, the resulting report data is truncated. Use filtering to avoid this.
