New Features and Enhancements in AP2 Snickerdoodle version 9.53.0

This section describes the features and enhancements that are included in Skylar One AP2 Snickerdoodle version 9.53.0.

Business Services

You can no longer delete a service policy that is aligned to an existing service.
Improved scalability: Services now support a maximum of 5,000 constituents per service. The default remains 100; contact ScienceLogic Support if you want to adjust the number of supported constituents in your system.
Improved the performance and reliability of retrieving service performance data for business services with a large number of constituents.
You can now realign multiple business services to a different service policy simultaneously from the Business Services page, so long as the selected services share a common type.
You can now set a custom default service policy for each service type (Device, IT, Business, and Aggregate). A new service inherits the default policy for its type.
Added an Advisories swimlane to the Service Investigator timeline for Skylar AI advisory events.

Device Management

Redesigned the Thresholds tab of the Device Investigator.
Added Collector Name and Collector ID columns to the Devices page to identify the specific Data Collectors aligned to your devices.
Added a new Collector Group field on the Device Investigator's Info panel that lists the name and ID of the collector group aligned to the device. Additionally, updated the existing Collector field, which previously displayed the device's collector group, to instead identify the name and ID of the Data Collector aligned to the device.
Changed the "Windows Services" monitoring policy label to "Services" throughout the user interface.

Event Management

Added External Ticket 2 and External Ticket 3 as optional columns that can be included on tables that list cleared and masked events. Also, added the ability to use these columns to filter active and cleared events tables.
Added a banner with a link to Skylar Advisor at the top of the Event Investigator page for Skylar AI advisory events.
Added the ability to filter event tables by the Age column. You can filter by an absolute date range using the Between, Before, After, or At options, or by a relative age.

GraphQL (GQL)

Ensured that you cannot add a Global Manager system as a stack using the createStack mutation.
Added the cbqosObjectsByInterface query to support listing Class-Based Quality of Service (CBQoS) policies per interface in GQL.
Expanded interface queries and mutations in GQL to support all available interface properties.
Added a new updateDefaultHarPolicies mutation to manage default policies for each service type.

Platform and Security

AP2 version 9.53.0 (Snickerdoodle) includes package updates to improve security and system performance. These package updates include security updates that address the following known vulnerabilities: CVE-2026-19481, CVE-2026-19484, CVE-2026-74866, CVE-2026-87776.
Added a configurable list of trusted reverse proxies. Skylar One now accepts the X-Forwarded-For request header only from the proxies you list in /etc/nginx/conf.d/trusted-proxies. The shipped file trusts every address by default, so you must edit the list if you want to limit the proxies trusted. Any edits you make are retained when you upgrade.

System Administration

Added a new Password Policy page (System > Settings > Security > Password Policy), where you can configure password policy settings globally or for specific organizations, user policies, or user accounts. This page appears only in the default user interface (AP2); there is no classic user interface equivalent.

User Interface

Added an optional user preference page where you can set a timezone and a date and time display format for AP2 native pages. This page is disabled by default; an administrator can enable or disable it on a Skylar One stack using the settingsUseDateTimeUserPreferences GQL feature toggle.
Updated date and time selection throughout the user interface with a four-column picker (hours, minutes, seconds, AM/PM). This replaces the previous analog clock views.

Known Issues

The following known issues affect version 9.53.0 of the Skylar One AP2 Snickerdoodle release:

Business Services

On the Business Services page and the Devices page, converting a basic filter to an advanced search filter and then clearing the advanced filter can cause the page to crash. To work around this issue, refresh the page. (Jira ID: SLUI-23674)
On the Business Services and Devices pages, searching by name, opening a record, and then returning to the list can cause the search field to stop working correctly. To work around this issue, click the gear icon next to the search field and click Clear a second time. (Jira ID: SLUI-24160)
The Time Taken to Complete HAR Refresh and Time Taken to Complete Hierarchy Calculation line chart widgets on the Service Insights page (Business Services > Service Insights) might display data that goes back further than seven days, and might appear empty on systems that have not yet accumulated sufficient data. (Jira IDs: SLUI-23818, SLUI-23816)
When creating a service from a template, the resulting service might receive a copy of the policies, even if the Make copy of policies checkbox is not selected. (Jira ID: SLUI-23102)
The filter to select devices or services during service creation from templates is not editable. (Jira ID: SLUI-23247)
With DEBUG logging enabled, the Business Service Management export path can log an "OSError: Message too long" error when a log record exceeds the syslog datagram size. (Jira ID: SLUI-23972)
When Business Service Management metric export is enabled, the OpenTelemetry export can repeatedly log an "Invalid type NoneType" exception for ruleset-level records that have no rule ID. (Jira ID: SLUI-23970)

Dashboards

Editing the scale prefix of a Devices widget using the Leaderboard visualization does not update the Storage Used column in the widget's table. (Jira ID: SLUI-22198)
Creating a Devices widget using the Line Chart visualization, then toggling on Area Chart and then selecting either Percentage or Normal from the Stack Options field, can cause the line chart to not display. (Jira ID: SLUI-22592)
When editing a Devices widget that uses storage metrics, selecting a scale prefix and saving does not apply the change. The scale prefix selection is not retained after saving. (Jira ID: SLUI-23777)
In a Devices widget using the Table visualization, columns for configuration Dynamic Application objects cannot be resized; dragging the column boundary snaps back as soon as you release it. (Jira ID: SLUI-24322)
When creating or editing a Devices widget using the Table visualization with the Title links to another page checkbox selected and Dashboards selected from the Link type field, removing the selected dashboard causes the Save Widget button to disable, preventing the widget from being saved. (Jira ID: SLUI-23172)
Editing an Events widget and setting the Refresh Mode field to None still displays the refresh mode as automatic in the widget's event table. (Jira ID: SLUI-21947)
When a File Systems widget using the Leaderboard Bar Chart visualization is driving a subscribed table and multiple selections are made in the bar chart, the "%" unit label appears in the Data Used column of the table instead of the correct kilobyte (kB) unit. (Jira ID: SLUI-10317)
Creating an Interface widget with the Leaderboard visualization, applying an advanced filter, and adjusting the data time span using the Time span filter results in an error. (Jira ID: SLUI-22200)
When editing a widget using the Line Chart visualization, deleting the default "0" in the Threshold Line field prevents the widget from being saved. (Jira ID: SLUI-22591)
In widgets using the Table visualization that have specific entity selections, deleted entities might still appear in the widget configuration after those entities are removed. (Jira ID: SLUI-23229)
Using the Comfortable density setting in widgets with the Table visualization might cause the "Find column" menu under Column Preferences to not display column options until the widget is resized. (Jira ID: SLUI-23171)
When editing a widget in the Edit Widget modal, if a dashboard has a driving and subscribing widget connected by a custom context, toggling on the This widget can drive other widgets and saving the widget causes the custom context to disappear from the context drop-down field when the toggle is re-enabled, even if the subscribing widget is still using that context. (Jira ID: SLUI-23151)
The Select All checkbox on the Dashboards page only applies to dashboards that are currently loaded and visible in the list, and does not include additional dashboards that load as you scroll down. (Jira ID: SLUI-23686)
A noticeable delay might occur when interacting with dashboard widgets, such as creating a widget, selecting metrics and properties, or editing a widget. (Jira ID: SLUI-23901)
Users without the TKT_ACCESS_EXTERNAL access hook can still add the External Ticket, External Ticket 2, or External Ticket 3 column to an Events dashboard widget and view its values. (Jira ID: SLUI-24076)
When you edit an existing Service widget that was configured with all available Service Type options, the widget might revert to the Business Service type after you save it, even if you do not change any field. (Jira ID: SLUI-24064)

Device Management

On a device's Attributes tab, aligning or unaligning an extended custom attribute and then clicking Save can display a false "An error occurred while saving" message, even though the change saves correctly. To work around this issue, refresh the page; the attributes grid then reflects the change correctly. (Jira ID: SLUI-24259)
On the Thresholds tab of the Device Investigator, expanding threshold cards in Firefox can display a styling issue. (Jira ID: SLUI-24107)
On the Thresholds tab of the Device Investigator, a threshold value and its unit might be truncated when both are long. For example, a value of "10000" with the unit "interfaces" might display as "10 interfaces". (Jira ID: SLUI-24340)
In the device Info box, editing and saving only one of the Organization, Device Class, or Device Name fields displays the original value again when you reopen the Info box within the same page session. To work around this issue, reload the page. (Jira ID: SLUI-24189)
On the Devices page, when sorting your search by the Organization column, the inventory table sorts by Organization ID instead. (Jira ID: SLUI-21459)
The assigned organization for devices might not always update, even after performing a bulk alignment organization action on the Devices page. To work around this issue, refresh your browser immediately after completing the bulk alignment action. (Jira ID: SLUI-21483)
You might experience an issue where the Devices page loads only the first 30 devices and otherwise continually indicates that the page is loading. (Jira ID: SLUI-23248)
When sorting by columns on the Device Investigator page in Firefox, the table might continuously attempt to retrieve results unsuccessfully. (Jira ID: SLUI-21095)
The Device Categories page (Devices > Device Categories) fails to load properly whenever there is a category with a null ID. To work around this issue, go to the Device Categories page (System > Customize > Device Categories), locate the category with the null ID, and then delete that category by clicking the delete icon () next to the category. (Jira ID: SLUI-20731)
If you edit a device's name from the blue menu bar at the top of the Device Investigator, the Edit button might become disabled. If this occurs, refresh the page to re-enable the Edit button. (Jira ID: SLUI-24418)

Discovery

In the guided and unguided discovery wizards, the Collector drop-down field does not visually reflect the selected value, instead displaying "[object Object]". The Save and Run button is also not disabled when no collector is selected. To work around the display issue, click Back and then Next in the wizard (or cancel and reopen the wizard) to force the step to re-render with the correct collector name. (Jira ID: SLUI-24290)

Events

The events on the Events page cannot be sorted by the Organization column. (Jira ID: SLUI-20903)
From the Event Policies page (Events > Event Policies), you can delete only a single event policy at a time, even if you select multiple event policies for bulk deletion. (Jira ID: SLUI-20853)
The event age shown on the Events page might not match the age shown on the Classic Events page, which can cause a discrepancy between the events that display based on the Age column filter depending on which page you are viewing. (Jira ID: SLUI-24125)
The External Ticket, External Ticket 2, and External Ticket 3 values appear as clickable links on the Events page but as plain text on the event details page. (Jira ID: SLUI-24124)
Pasting text into the code view of the event policy Description field and saving immediately might not save the change; editing and saving the policy a second time saves it correctly. (Jira ID: SLUI-24103)
Some event policy descriptions might not render correctly on the Event Policy Editor page. (Jira ID: SLUI-24102)
Filtering the Last Edited column on the Event Policies page (Events > Event Policies) by a date or time range might return no results, even when matching event policies exist. (Jira ID: SLUI-21029)

Global Manager

On a Global Manager system, the stack cache does not refresh after a credential aligned to a child stack is updated, which can cause queries against that stack to use a stale credential. (Jira ID: SLUI-24288)
The devices on the Devices page in Global Manager systems cannot be sorted by the IP Address column. (Jira ID: SLUI-21108)
On Global Manager systems, the View Event Policy option in the Actions menu () on the Events page does not work as expected. (Jira ID: SLUI-21133)
On Global Manager systems, the Events page does not display events from child stacks. To work around this issue, clear all system caches on both the child stacks and the Global Manager parent stack, then restart the NextUI service. (Jira ID: SLUI-21134)
On Global Manager systems, the ID column in organization widgets and device widgets now displays the organization's GUID rather than the intended stack ID and organization ID. (Jira ID: SLUI-22654)

GraphQL (GQL)

The monitorSslCertificates query can fail with a "Failed to fetch monitors data" error. There is no workaround for this query directly, but you can retrieve the same SSL certificate monitor data through the device query instead. (Case: 00715444) (Jira ID: SLUI-24235)
The harProviderOnDemandProcessing query incorrectly creates a service table in the data_har database when executed with invalid or non-existent service IDs. (Jira ID: SLUI-21135)
The monitorMetricDataSearch query for device monitor metrics returns an internal server error. (Jira ID: SLUI-23619)
Clicking the Run Now button for any Dynamic Application on the Collections tab of the Device Investigator displays the following GQL error message: "Variable "$procId" of non-null type "ID!" must not be null." (Jira ID: SLUI-21070)
In the GQL browser, the auto‑complete suggestions for queries and mutations can fail to load and instead show an error in the user interface and browser console, preventing type‑ahead help while editing requests. (Jira ID: SLUI-23433)
The deviceTraceRoute mutation might return an error instead of running the traceroute. (Jira ID: SLUI-24157)
A query for Dynamic Application metric data on a device might return empty results when that device is retrieved as part of a multi-device search, even though the same query succeeds for a single device. (Case: 00699859) (Jira ID: SLUI-24126)
In Global Manager, the deviceThresholds query does not support the globalManagerStackSearch filter. To request thresholds for a device on a managed stack, use a stack-prefixed device ID. (Jira ID: SLUI-24038)

Maps

When creating or editing a geographic map, filters applied in one map might be hidden if the related column is hidden in another map. To work around this issue, click the gear icon (), select Column Preferences, and then click Show All. Alternatively, you can click the gear icon () next to the filter field (used to search devices or services) and select Clear. This prevents columns from being hidden or shown while preserving your applied filters. (Jira ID: SLUI-22809)

Skylar AI

If you click on a device name link on the Anomaly Detection page, a different device record might open. (Jira ID: SLUI-24391)

System Administration

When editing a collector group from the Collector Groups page (Manage > Collector Groups) by clicking its Actions menu (ellipsis icon) and clearing two or more organizations in the Limit access to specific organizations field of the Edit Collector Group modal, the Organizations column on the Collector Groups page shows that only one organization was deselected, even if multiple were. (Jira ID: SLUI-22167)
Message Collectors on the Collector Groups page (Manage > Collector Groups) cannot be sorted by the Message Collectors column. (Jira ID: SLUI-22099)

User Interface

Name changes to nodes are not saved on the Nodes page (Manage > Nodes). (Jira ID: SLUI-22248)
The filter for columns where you can select a date (such as on the Events or Event Policies pages) might show an error in the browser console when using the "Before," "After," or "At" options. (Jira ID: SLUI-23421)
The Skylar AI icon still appears in the basic menu even after the Skylar AI connection is disabled. (Jira ID: SLUI-23327)
Clicking Clear Filters once on a table-based list page (such as Devices, Business Services, Events, Maps, or Dashboards) might not clear the filter if clicked shortly after typing in a column filter; click Clear Filters a second time to clear it. (Jira ID: SLUI-24108)
After you upgrade to AP2 version 9.53.0 (Snickerdoodle), if your browser uses a non-U.S. locale, the dates and times that display in inventory tables throughout the user interface might conform to the format used by your browser's locale rather than the original U.S.-style format. (Jira ID: SLUI-24399)
