    The Add new device window is displayed.

  3. Describe the device and click Test to test it.

  4. Click Finish to save your device configuration and return to the Devices screen.

    You can click Finish to save a failed configuration, perhaps because you know the description is correct but the device is temporarily unavailable, or because you want to go back and edit the configuration later.

  5. After you add a device, it is listed on the Devices tab, where you can access a menu of device configuration options.
    To re-open these connection configuration screens, select Edit connection from that menu.

See Add device for details on adding a device.

Devices tab

The Devices tab lists all configured devices and presents a brief status view of the selected device. The information displayed depends on the type of the device selected.

If you select a report server, the Devices tab splits into two tabs:

  • Device status shows statistics on the selected device.
    See below for details.
  • Farm configuration shows any report server farm involving the selected device.
    For information on configuring and managing report server farms, see Report server farm.

Connection

Presents information about the current connection status and reports any connection errors (including the response received from a connection query). The Last check value indicates the time and date of the last connection attempt to the selected device. NAM Probe devices report statuses on connections specific to their device type. For example, while all devices report Connection status, NAM Probe devices report additional connection statuses for:

  • Guided Configuration
  • SNMP health
  • Simple Parser data
  • Flow Collector status

Configuration

Presents details related to the configuration file for the selected device.

The Last read value indicates the time and date of the last attempt to read the configuration file.

The configuration status displays the statuses of the specific elements of the configuration file. The elements of the configuration file vary depending on the device type that is selected. For example, the configuration status for a NAM Server device contains the status for the Software Services element; a NAM Probe device cannot report such a status.

  • Read Configuration
  • Sent Configuration
  • Service, Module and Task Assignments
  • Software Service Dictionary
  • Software Services

The configuration status list closes with the Current status of a configuration file. The Current configuration indicates the publishing time and date, while the Draft and Pending configurations indicate whether a draft configuration is present or configuration publishing is pending.

Licensing

The statuses presented here apply to licenses for the particular NAM Probe. The statuses are grouped in two categories:

  • License capacity status
    This link will take you to the NAM Probe capacity report on the report server where you can explore the capacity and resource utilization of any deployed NAM Probes.
    For more information, see NAM Probe capacity report.
  • License activation status
    This link will take you to the license manager in the NAM Console where you can administer your licenses.
    For more information, see Licensing.

Hardware health

Presents information on the Hardware Health of the selected device. The Last read value indicates the time and date of the last attempt to read the health statuses. This information is available for NAM Probe and NAM Server devices.

The Hardware Health section presents the summary of the Capacity status report.

Note

NAM Probe status information is provided by a NAM Server, so you need a NAM Probe and a NAM Server added to your NAM Console, and both devices must be connected to each other.

For NAM Server devices

  • Average data files processing time (last 24 hours)
  • Daily performance data maintenance
  • Daily database maintenance
  • Daily report generation

For NAM Probe devices

  • CPU utilization
  • Memory utilization
  • Disk utilization

Click the Capacity Status link to see a full report. For more information, see Capacity Status.

NAM Server

  • Memory Utilization
    Shows the percentage of used memory during a predefined period of time, in comparison with the predefined memory threshold. By default, the memory threshold is set to 80%, and if it is exceeded, a memory alert is raised.
  • Number of Sessions
    Shows how many sessions are stored in the server cache memory.
  • Average Data File Processing Time
    Shows the average data file processing time versus the predefined threshold during the last 24 hours, and whether the long processing time alert was raised. By default, the threshold for data processing time is set to 60% of the monitoring interval.
  • The Nightly Tasks Execution Time section shows how long (on average for a selected period of time) it took to execute three tasks:
    • Daily Report Generation Data aggregation, calculation of trends and baselines, pre-defined DMI reports, and processing other data required for rendering reports.
    • DBDailyMaintenance Data aging, cleaning caches, database daily maintenance of sites, domains, and finding new sites and servers to monitor.
    • RTMDailyDataStore Closing the current day before storing performance data for the start of the next day. The Nightly Tasks Execution Time graph also shows whether the execution time for any of the above tasks exceeded the predefined timeout, raising the long execution time alert.
  • Business Units
    Shows the number of defined tiers, reporting groups and applications in each reported period.
  • Business Units Associations
    Shows the number of associations between the business units and sessions as defined by a combination client, server and URL.

NAM Probe

  • Packet drops
    Drop performance indicator expressed as percentage of dropped packets from received packets. Dropped packets are typically a result of hardware or resource failure.
  • CPU performance
    CPU performance indicator expressed as CPU usage per thread expressed in percent.
  • Memory usage
    Memory performance indicator expressed as the amount of memory used by NAM Probe data objects. This is equal to the number of object multiplied by the size of the objects.
  • File systems utilization
    Disk performance indicator expressed as the percentage of occupied disk space on the NAM Probe.

Traffic quality

Hover the pointer over any status indicator for a full description of that statistic.

  • Drop status
    Drop performance indicator expressed as percentage of dropped packets from received packets.
  • Sampling volume
    Percentage of sampling dropped in controlled manner.
  • SSL status
    Percentage of all SSL TCP sessions minus successfully decrypted SSL TCP sessions divided by all SSL TCP sessions counted for last sampling interval.
  • Sequence number gap rate
    Percentage of total missing sequence numbers from number of all sequence numbers observed in a last sampling interval.
  • Traffic diagnostics
    See Traffic diagnostics report.

Process Health

Presents information on the Process Health of the selected NAM Probe device. The Last read value indicates the time and date of the last attempt to read the health statuses for the selected device. This information is available only for NAM Probe devices.

The Process Health section presents the list of NAM Probe services critical for reliable operation of the device, proper configuration, and successful monitoring:

  • adlexpage2trans
    This service is responsible for post-processing of the monitored data and creating the log of transactions.
  • adlexrtm
    This service is responsible for the monitoring software and its configuration and performs the main analysis.
  • adlexv2page
    This service is responsible for post-processing of the monitored data and creating the log of operations.
  • avgt
    This service is a DNA agent responsible for communication with the DNA console and executing its monitoring and capturing requests.
  • cba
    This service is responsible for interactive configuration of the NAM Probe.
  • cba-agent
    Console Basic Analyzer agent provides communication between the CBA and the NAM Console.
  • rtmgate
    This service is part of the data flow and connections between different components within the deployment. It provides performance data and receives the configuration from the NAM Console.
Note

If a device within your Dynatrace infrastructure is unable to report detailed status information to the manager, some sections may report that the information is unavailable. This does not indicate a problem with a device.

Farms tab

Instead of individual devices, you can click the Farms tab to list all report server farms.

A report server farm is a collection of report server clusters sharing configuration and management options.

Example Farms tab:
