New features

DMS core functionality

DataMiner Object Model: Defining a script execution action that will execute an interactive Automation script [ID 33513]

It is now possible to define a script execution action that will execute an interactive Automation script.

Process:

  1. A client requests the execution of a DOM action in which the execution of an interactive Automation script has been defined via the domHelper.DomInstances.ExecuteAction() method.

    To indicate that the Automation script is an interactive Automation script, the IsInteractive property of the ExecuteScriptDomActionDefinition must be set to true.

  2. The domHelper.DomInstances.ExecuteAction() method replies immediately.

    • Its TraceData contains a DomActionInfo object in which type is set to DomActionInfo.Type.ScriptExecutionId.
    • The info object has an ExecutionId property that contains the execution ID of the script that was triggered by the DOM action.

  3. The client sends a ScriptControlMessage of type Launch using the script ID that was returned and will then receive ScriptProgressEventMessages.

Note

The connection used by the DomHelper sending the DOM action execution request should also be used to interact with the script.

New BPA test 'Verify Cloud DxM Version' [ID 33956]

This new BPA test checks if the minimum required version is installed for all DxMs in the system.

It is available from DataMiner 10.2.8 and 10.2.0 [CU6] onwards. You can run it in System Center (on the Agents > BPA tab), and it also runs automatically when you upgrade to 10.2.0 [CU6]/10.2.8 or higher.

For more information, see Verify Cloud DxM Version.

DataMiner upgrade: When VerifyClusterPorts prerequisite fails the user will now receive more information on why it failed [ID 33979]

When, during a DataMiner upgrade, the VerifyClusterPorts prerequisite fails, you will now receive more information on why it failed. For example, the DMS.xml file could contain faulty IP addresses or NATS may have silently failed.

DMS Cube

Visual Overview - Resource Manager component: Passing elements, services or views using the YAxisResources variable [ID 33402]

From now on, you can pass elements, services, or views to the YAxisResources session variable in order to show the corresponding resource bands.

Passing elements

You can pass elements by name or by ID as a string of comma-separated values.

In case an element is configured as an element reference in a resource, as a main DVE element in a function resource, or as the element corresponding with a virtual function resource, the corresponding resource will be shown.

In the following example, three elements are passed: an element with the name "MyElement", the element to which the Visio drawing is linked, and the element with ID 123/456:

YAxisResources:Element=MyElement,[this element],123/456

The corresponding resource bands are not updated automatically in case there is a change to the configuration of the elements.

Passing services

You can pass services by name or by ID as a string of comma-separated values.

The resources of the bookings linked to the services will be shown.

In the following example, three services are passed: a service with the name “MyService”, the service to which the Visio drawing is linked, and the service with ID 123/456:

YAxisResources:Service=MyService,[this service],123/456

To also show resources for contributing bookings, in the ComponentOptions shape data field of the Resource Manager component, specify Recursive=True.

The resource band will be updated in real time, based on the linked booking. This means that when you add or remove resources in a booking, you will immediately see the effect on the timeline.

Passing views

You can pass views by name or by ID as a string of comma-separated values.

When you pass a view, for any elements in that view that are configured as an element reference in a resource, as a main DVE element in a function resource, or as the element corresponding with a virtual function resource, the corresponding resources will be shown.

In the following example, three views are passed: a view with the name "MyView", the view to which the Visio drawing is linked, and the view with ID 123:

YAxisResources:View=MyView,[this view],123

To also show resources for elements in child views, in the ComponentOptions shape data field of the Resource Manager component, specify Recursive=True.

The corresponding resource bands are not updated automatically in case there is a change to the configuration of the elements.

Failover: Current Failover DMA status will now automatically be refreshed every minute [ID 33426]

In the Failover Config window as well as the Status dialog box, the current Failover DMA status will now automatically be refreshed every minute.

Visual Overview - Resource Manager component: Selecting multiple resource bands in the timeline [ID 33536]

In the timeline of an embedded Resource Manager component, it is now possible to select multiple resource bands.

To select more than one resource band, click one, and then click another while holding down the Ctrl key, etc. To select a list of consecutive resource bands, click the first one and then click the last one while holding down the Shift key.

When you select more than one resource band, the SelectedResource session variable will contain the GUIDs of all selected resources, separated by commas.

Trending - Behavioral anomaly detection: Enhanced detection of change points of type 'flatline' [ID 33559]

Up to now, a change point of type “flatline” would be detected when the parameter value remained constant for more than 3 polling times. From now on, instead of counting polling times, a running estimate will be kept of how long the parameter typically remains constant.

If this estimate exceeds 1 hour, no change points of type “flatline” will be detected. Else, a change point of type “flatline” will be detected if the parameter value was not constant in the last hour but is constant again for more than 3 times the running estimate.

Visual Overview - Resource Manager component: Enhanced way of selecting a time range [ID 33580]

In the timeline, the context menu will no longer open automatically after selecting a time range by means of drag-and-drop. Instead, it will now only open when you right-click.

This change in behavior will now allow you to trigger a script by clicking an action button instead of selecting an option in the context menu of the timeline. In other words, you will now be able to proceed as follows:

  1. Select a resource band.
  2. Select a time range.
  3. Click an action button.

The SelectedTimeRange variable will now be cleared when the time selection is cleared (i.e. when it is no longer visible/available). Up to now, this variable would only be cleared when the selection was changed.

System Center - Agents: BPA Details window now has a Copy button that copies the list of errors to the Windows clipboard [ID 33638]

When, in the BPA tab of the Agents section, you see a BPA test that returned errors during its last run, you can click “...” to open a Details window listing those errors.

At the bottom of this Details window, you can now find a Copy button that allows you to copy the list of errors to the Windows clipboard.

Visual Overview: [this reservationID] placeholder [ID 33669]

In shape data or shape text of shapes linked to a booking (e.g. dynamically generated shapes that represent bookings), you can now use a [this reservationID] placeholder to retrieve the GUID of the booking.

See the following examples:

[Resource:[reservation:[this reservationID],ResourceID|NodeID=18|],Name]

[reservation:[this reservationID],Property=Monitoring]

DMS Automation

Added the option to skip the 'script started' information event [ID 33666]

When sending an ExecuteScriptMessage, you can now specify that no “Script started” information event should be generated when the script is executed. To do so, add the SKIP_STARTED_INFO_EVENT:TRUE option to the string array as shown in the following example.

ExecuteScriptMessage esm = new ExecuteScriptMessage("Script")
{
    Options = new SA(new[]
    {
        "OPTIONS:0",
        "CHECKSETS:TRUE",
        "EXTENDED_ERROR_INFO",
        "SKIP_STARTED_INFO_EVENT:TRUE"
    })
};
engine.ExecuteScript(esm);

Also, the SubScriptOptions class has been extended with a SkipInitialInfoEvent property that can be used to pass the above-mentioned option to subscripts. See the following example.

var options = engine.PrepareSubScript("SubScript");
options.Synchronous = true;
options.PerformChecks = false;
options.SkipStartedInfoEvent= true;
options.StartScript();

DMS web apps

Dashboards app: Service Definition component now supports both types of process automation service definitions [ID 33615]

The Service Definition component now supports both types of process automation service definitions:

  • Skyline Process Automation
  • Custom Process Automation

GQI: Data source 'Get custom data' renamed to 'Get ad hoc data' [ID 33795]

The data source “Get custom data” has been renamed to “Get ad hoc data”.

Dashboards app - Visual Overview component: Loading bar at the top of the component instead of large loading message on top of the component [ID 33829]

When a Visual Overview component was loading, up to now, a large loading message was displayed on top of the component. From now on, when a Visual Overview component is loading, a loading bar will appear at the top of the component instead.

DataMiner Application Framework: Action editor window can now be closed by clicking the OK button [ID 33853]

The action editor window can now be closed by clicking the OK button.

DataMiner Cube - ListView component: No longer possible to filter on columns of type datetime [ID 32900]

In the ListView Component, from now on, it is no longer possible to filter on columns of type datetime.

Enhanced BPA error message [ID 33393]

Up to now, when a BPA test could not be executed on an offline Failover agent, it would return the following error message:

This BPA does not apply for this DataMiner Agent.

From now on, it will return the following error message instead:

This BPA does not apply for this DataMiner Agent: cannot run on Offline Failover Agent.

GQI queries: Enhanced performance when retrieving custom properties [ID 33538]

Because of a number of enhancements, overall GQI query performance has increased when retrieving custom properties for views, services and elements.

NATS: Enhancements to the NATS configuration [ID 33558] [ID 33931]

A number of enhancements have been made to the NATS configuration:

  • STAN clustering has been removed.

  • New NATSForceManualConfig option to disable the automatic reset timer in NATSCustodian.

    Disabling the timer can be done in one of the following ways:

    • Set the SLNet option “NATSForceManualConfig” to true in the SLNetClientTest tool (default = false).
    • Set the SLNet.NATSForceManualConfig tag to true in MaintenanceSettings.xml.
Note
  • Changing this option in the SLNetClientTest tool can be done at run-time. The change will be applied immediately.
  • Forcing manual configuration will disable the automatic NATS configuration on the DataMiner System. It will then be up to the user to either manually configure a NATS cluster or manually call NatsCustodianResetNatsMessage when changes are made to the DMS.
  • On DataMiner startup, NAS and NATS will now automatically be started if they are not running.

Also, the nats-streaming-server binary has been updated to v0.24.6. However, note that it will not be updated automatically via upgrade actions. It will only be installed during fresh NATS installations or when reinstalling NATS via SLEndpointTool_Console. The previous version (v0.22.0) and the new version (v0.24.6) version are compatible and are able to communicate with each other.

Service & Resource Management: A booking will now be set to 'interrupted' when whatever event related to that booking could not be executed [ID 33576]

Up to now, when DataMiner was unavailable when a booking was supposed to start or stop, its state was set to “interrupted” when DataMiner started up again.

This functionality has now been extended. A booking will now also be set to “interrupted” when whatever event related to that booking could not be executed.

DataMiner Cube - Alarm Console: 'Add to incident' menu option no longer available when right-clicking alarms that cannot be added to an incident [ID 33591]

From now on, the “Add to incident” menu option will no longer be available when you right-click an alarm that cannot be added to an incident:

  • Active alarms with severity “normal” (i.e. clearable alarms that have not been cleared yet)
  • Alarms with a source other “DataMiner System” (e.g. correlation alarms)
  • Alarms associated with DataMiner itself
  • Notices, errors, information events and suggestion events

DataMiner Upgrade: Additional action to delete legacy custom data templates [ID 33628]

In DataMiner main version 10.0.0 CU11 and feature version 10.1.1, new Elasticsearch templates for custom data indices were introduced to support adding new fields after index creation. An upgrade action has now been added to remove all legacy Elasticsearch templates from the system. During the first DataMiner startup after the upgrade, the templates will then be recreated.

Dashboards app: Enhanced 'loading' indication when state component linked to a GQI query receives an update [ID 33640]

Up to now, each time a state component linked to a GQI query received an update, a “loading” indication would be displayed over the entire component. From now on, when such a component receives an update, a more subtle loader bar will be displayed instead.

Also, when a query error occur, from now on, the actual error will be displayed instead of “No data”.

Business Intelligence: Enhancements made to the automatic SLA data clean-up mechanism [ID 33663]

A number of enhancements have been made to the automatic SLA data clean-up mechanism.

GQI: Enhanced performance when running a GQI query with a filter applied to it [ID 33664]

  • In the Advanced > Virtual IP Addresses tab, the columns are now wide enough to display the full IP address/mask.
  • The Advanced > Heartbeats tab now indicates which heartbeats are inverted.

Clearer error message will now appear when a DataMiner Agent cannot be reached [ID 33752]

When a DataMiner Agent could not be reached, in some cases, an “Attempt to use an unauthenticated connection” error would appear in the log files or on the UI. From now on, a clearer error message will appear instead.

DataMiner Application Framework: Splash screen of apps now shows 'Low-code apps' instead of 'Apps' [ID 33798]

When you start up a custom low-code application created using the DataMiner Application Framework, its splash screen will now show “Low-code apps” instead of “Apps”.
