v1.11.2 — Debug Multi-Collector Fixes & API Explorer Polish

v1.11.2August 2026

This patch release fixes multi-collector debug runs stalling on offline collectors, corrects the !tail command parameter schema, clears stale collector selections on portal change, and improves API Explorer response handling and path variable substitution.

Added

API Explorer — Download response — Copy and download the active response view (JSON, raw, headers, or snippets) as a text file with a method/path/status filename.
API Explorer — Single-brace path variables — Environment variables now resolve OpenAPI-style {id} placeholders in paths in addition to {{variable}} syntax.

Improved

Multi-collector debug — Streaming results — Each collector’s result appears as it finishes instead of waiting for the entire batch to complete.
Multi-collector debug — Progress — Results header shows N/M complete and pending collector tabs display a polling state while runs are in flight.
Debug collector picker — Offline collectors cannot be selected; Select All and group select only include online collectors.

Fixed

!tail command — Added the required lines parameter so commands build as !tail <path> <lines> [pattern] (e.g. !tail debug.log 1000 ERROR) instead of omitting the line count.
Offline collectors stalling batches — Dead or offline collectors fail immediately with an error instead of polling for up to two minutes and blocking other collectors in the same run.
Portal change collector selection — Switching portals clears debug session collector selections so IDs from the previous portal are not carried over.

v1.11.1 — Extension Storage Quota Fix

v1.11.1August 2026

This patch release fixes extension storage quota errors caused by unbounded API Explorer history and hardens how large history data is persisted across the editor.

Added

Settings → Storage — View per-key chrome.storage.local usage, refresh totals, and clear API or execution history to free space.
Execution output size limit — New editor preference (default 64 KB) trims saved script output in execution history.

Improved

API history compaction — Re-applies entry limits and response trimming on load; enforces a global byte budget and offloads large bodies to IndexedDB.
Execution history compaction — Same policy as API history: output size limits, global budget, and IndexedDB offload for large payloads.
Quota-aware storage writes — Failed writes due to quota exhaustion evict history storage and show a user-friendly toast instead of raw Chrome errors.
Collector sizing persistence — Workspace state moves from chrome.storage.local to IndexedDB (legacy data migrates automatically on load).

Fixed

Resource::kQuotaBytes quota exceeded — API Explorer history could grow past the 10 MB chrome.storage.local limit (especially across many portals), blocking preferences, debug state, and other extension saves.

v1.11.0 — Collector Sizing: NetFlow Profiles & Ingestion Defaults

v1.11.0August 2026

This minor release adds NetFlow PSR profile sizing and customizable ingestion source defaults to the Collector Sizing Calculator, with safer reset behavior and richer PDF settings documentation.

Added

NetFlow Profile settings — Choose collector OS (Linux/Windows), PSR ingest profiles (P1–P4), legacy pre-PSR baseline, or custom flows/sec per collector size.
Ingestion Sources settings — Customize default EPS for system logs and SNMP traps and default FPS for NetFlow source types; add custom source types from project settings.
PDF settings appendix — Documents log/trap/flow defaults, NetFlow profile selection, and separated polling vs NetFlow capacities.

Improved

NetFlow capacity model — NetFlow collector sizing uses profile-based flows/sec tables instead of a single FPS column on polling capacities.
Project migration — Stored projects with legacy flows/sec on collector capacities migrate to legacy or custom NetFlow profiles.
Load sync — Site worksheets align with merged ingestion defaults when projects load from storage.

Fixed

Reset preserves counts — Resetting ingestion source or device type defaults restores OOB rates and specs without clearing worksheet counts.
Custom profile snapshot — Switching to Custom NetFlow profile copies the currently displayed recommended FPS values into editable custom capacities.

v1.10.1 — Health Report Tables & Debug Portal Polish

v1.10.1August 2026

This patch release adds health report table sorting and fullscreen viewing, a custom free-form debug command, and fixes OK-only report labeling and truncated portal output handling.

Added

Health report table sorting and fullscreen — Click column headers to sort; open any report table in a fullscreen dialog with a sticky header. Sort order is preserved between inline and fullscreen views.
Custom debug command — Run any collector-supported cmdline from the Debug workspace (e.g. !tlist, !version, multiline !groovy) without picking from the catalog.

Improved

Debug API errors — Clearer LogicMonitor error messages when a collector rejects a debug command.
Process list columns — Windows vs Linux column layout uses collector platform from the report when available.

Fixed

OK-only health reports — Labels, chart titles, and summary metrics use success-oriented wording instead of failure-oriented defaults.
Truncated portal output — When the portal truncates health check JSON, the report shows a guided empty state with optional raw output instead of a broken parse view.

v1.10.0August 2026

This minor release introduces a persistent Debug Commands workspace, health check report sharing, editor read-only mode, unified welcome screens, and centralized keyboard shortcuts and actions.

Added

Debug Commands workspace — Tabbed sessions replace the modal dialog; configuration, collector selection, and results persist across workspace switches.
Health check export/import — Export a JSON report to share with teammates or customers; import shared reports back into Composer.
Editor read-only mode — Block portal configuration writes from Settings while still allowing script editing and execution.
Health check row limits — Configurable table row limits plus a full longest-running threads table.
Collector IDs in debug list — Debug command catalog shows collector IDs where applicable.

Improved

Unified welcome screens — Shared layout, quick-start actions, and workspace navigation across Script Editor, API Explorer, Debug Commands, and Collector Sizing.
Keyboard shortcuts — Centralized ⌘K chord registry with updated in-app and docs reference.
Actions menu — Single source of truth shared with the command palette for labels, ordering, and workspace switches.
Semantic icons — Consistent icon components across toolbar, dialogs, and workspace UI.

Fixed

Debug results tabs — Horizontal scroll on multi-collector result tabs.
AppliesTo tester — Copy device name instead of internal device ID.
Session drafts — Preserve drafts on extension update.
Dialog overflow — Layout fixes in several modal workflows.

v1.9.3 — Collector Health Check Overhaul & Snippet Fixes

v1.9.3July 2026

This patch release overhauls the Collector Health Check debug action with parallel collection, richer diagnostics, and a redesigned report UI. It also fixes built-in Groovy snippet and template compilation issues on collectors.

Added

Executive Summary — Headline findings, subsystem activity badges, dominant collection methods, sizing guidance, and agent configuration diffs.
Run Diagnostics — Parallel collection timing, warnings, and partial-report notices when the 120-second deadline is reached.
Netflow devices table — Surfaces netflow device collection data in the report.
Excessive instances table — Highlights devices with unusually high instance counts.
Failing !tlist details — Expanded per-module thread detail for failing collection tasks.
Partial report banner — Visible notice when collection times out before all tasks complete.

Improved

Health check script — Parallel task waves, improved parsers (tlist, adlist, tplist, splist, netflow), JVM sizing from wrapper.conf, thread pressure analysis, and enriched AppliesTo queries.
Report layout — Reorganized into cohesive chapters instead of nested cards, with full-width layout and a fixed Copy Output / Download Output toolbar.
Summary header — Unified metrics band at the top of the report; side-by-side tables now align correctly.
Suggested collector counts — Now include the S tier alongside M, L, XL, and XXL.
Groovy templates — LMDebugPrint converted from script-level closure to def method for collector compatibility.
Built-in snippets — Refactored to avoid script-level closures that conflict with LogicMonitor collector bindings.

Fixed

Built-in snippet examples — Several out-of-the-box Groovy snippets no longer fail to compile on collectors.
Toolbar collector size selector — Styling now uses correct Tailwind important syntax.

v1.9.2 — API Explorer Safety & Docs Improvements

v1.9.2June 2026

This patch release adds safety guardrails to the API Explorer, improves generated request bodies, makes the Docs tab more useful while building requests, and cleans up the request/response workspace.

Added

Destructive request confirmations — API Explorer can now prompt before sending destructive or write requests. Settings support DELETE only, all write methods, or off.
Read-only mode — Restrict the API Explorer to GET requests from Settings or directly from the API toolbar.
Docs insert actions — Insert documented query parameters, headers, and request body fields into the active request from the Docs tab.
Collapsible schema fields — Nested request-body schema fields in Docs can now be expanded and collapsed with rotating chevrons.

Improved

Docs-first API tools — Docs is now the first API Tools tab so endpoint documentation is visible immediately, even when variables and history are empty.
Better example bodies — Generated request body examples now include required schema fields first, use default values when provided, and skip read-only fields when marked by the schema.
Cleaner request builder — Query parameters and headers now live in one shared section while Body Form and Raw JSON only switch the body editor.
Better request/response split — The middle panel gives the response more usable default space and reduces nested scrolling in the request panel.
JSON Path value previews — Helpers now show typed, truncated value previews, including an explicit (empty) marker for empty strings.
Clearer disabled feedback — Disabled send, method, and endpoint controls now explain why the action is unavailable, including read-only mode and missing portal/path context.
Safer confirmation context — Destructive request confirmations now show the target portal hostname clearly without duplicating the portal subdomain.

v1.9.1 — Collector Sizing Report & Custom Device Polish

v1.9.1May 2026

This patch release improves the Collector Sizing Calculator with clearer project overview modes, richer PDF exports, worksheet notes, and fixes for custom device workflows.

Added

Site vs Combined Workloads — The Overview now separates Site Workloads from Combined Workloads so reports clearly show whether each site is sized independently or all sites are treated as one shared workload pool.
Worksheet notes — Add notes to device, log, trap, and NetFlow worksheet rows to capture assumptions, scope, or customer-specific context.
Report notes — Add an optional report-level note during PDF export for customer context, assumptions, or caveats.
Worksheet notes in PDF export — Include worksheet notes on per-site detail pages when exporting reports.

Improved

PDF report export — Export options now support site workload sections, combined workload sections, optional workload analysis, per-site details, worksheet notes, and settings appendix controls.
Overview reporting — Project overview summaries now make collector totals, resource requirements, site contributions, and workload drivers easier to compare.
Method ratio editing — Device method ratios are kept balanced at 100% when editing or removing methods, reducing confusing sizing outcomes.

Fixed

Custom device types on new sites — Custom device types created in Settings now appear correctly on sites created after the custom device type was added.
Deleted custom methods — Removing a custom collection method now removes it from device defaults and site worksheets instead of silently continuing to affect calculations.
Project imports — Collector sizing project imports now validate malformed project, site, workload, and settings data before recalculation so invalid files fail cleanly instead of breaking the calculator.

v1.9.0 — Collector Sizing: Projects, Import/Export, PDF Reports & Auto Sizing Fix

v1.9.0May 2026

This minor release centers on the Collector Sizing Calculator: projects let you manage multiple independent sizing scenarios, you can export and import project configuration as JSON, and you can print or save PDF overview reports. Auto sizing now recommends the smallest collector tier that fits your workload. Destructive actions ask for confirmation, and custom device types defined in settings participate correctly in sizing.

Added

Projects — Create multiple isolated sizing scenarios. Each project has its own sites, calculator settings (defaults, capacities, failover, forced size), and selected site. Switch the active project from the sidebar, rename inline, duplicate, or delete (when more than one project exists).
Import and export — Export any project to a JSON file for backup or sharing. Import a JSON file from the Projects header: if the file matches an existing project ID, choose to replace that project or import as a new copy (see the conflict dialog). Imports use the LMDA Composer project envelope format.
PDF overview reports — From Overview mode, open Export PDF in the toolbar to configure title, customer name, author, cover page, per-site detail pages, settings appendix, and workload analysis. The browser print dialog opens; choose Save as PDF to download.

Improved

Destructive action confirmations — Collector sizing now prompts for confirmation before destructive operations (for example removing projects or sites, resetting a project, or removing custom configuration), reducing accidental data loss.

Fixed

Auto collector size — When the toolbar size is set to Auto, recommendations now use the smallest collector tier whose capacity satisfies your estimated load at the configured max utilization. Previously, very small workloads could incorrectly default to a larger tier.
Custom device types — Custom device categories added under Settings → Device Types are again applied correctly to workload and sizing calculations so scenarios that rely on them produce valid recommendations.

v1.8.2 — API Explorer Toggles & Open in Composer Improvements

v1.8.2April 2026

This patch release improves API Explorer request editing for faster testing workflows and makes Open in LMDA Composer more reliable on updated LogicMonitor module pages.

Improved

API Explorer query params and headers can now be enabled or disabled without deleting the configured key/value pair, making it easier to flip request options on and off while testing
Executed API requests and generated request snippets now include only enabled query params and headers
Open in LMDA Composer button injection now supports both legacy and newer LogicMonitor module action bar layouts
Open in LMDA Composer now falls back to parsing portal edit URLs to determine module type and ID when datapath metadata is missing or delayed

v1.8.1 — Portal data (LMGlobalData)

v1.8.1March 2026

Portal data action button - Add new portal data action in the portal selection context menu (when your portal is active) opens a dialog that reads portal data from the open LogicMonitor tab.

Bug Fixes

Script Edtior find bar tooltip issue — Find/replace (⌘/Ctrl+F) hover UI could render under the editor tab bar, causing flicker and hard-to-click controls.

v1.8.0 — FedRAMP Domain Support & Collector Filtering

v1.8.0March 2026

This release adds full support for LogicMonitor FedRAMP (lmgov.us) domains and introduces searchable collector filtering in the context menu.

Added

FedRAMP Domain Support — lmgov.us portals are now automatically discovered, authenticated, and fully functional alongside logicmonitor.com portals. All portal discovery, content script injection, sender validation, and API communication work seamlessly across both domains.
Collector Search & Filtering — The collector selector in the execution context menu now supports searching and filtering by description, hostname, collector group name, or ID.

Improved

Health check portal links now read the server field from the collector’s agent.conf for correct URL generation on both commercial and FedRAMP collectors, with a fallback to company + .logicmonitor.com for backward compatibility.
Create Module wizard now displays the actual portal hostname instead of reconstructing it from the display name.

v1.7.5 — Debug Commands Fix & Execution Improvements

v1.7.5February 2026

This patch release fixes a critical issue where debug command parameters were not being passed to the collector, adds a Rerun button for debug commands, fixes execution timeout errors, and clarifies result action labels.

Bug Fixes

Fixed debug command parameters not being sent to the collector — positional arguments (host, OID, taskId, etc.) were incorrectly formatted as key=value pairs instead of bare values
Fixed positional arguments appearing before key=value options — options like version=v3 now correctly precede positional args (e.g. !snmpget version=v3 host .1.2.3)
Fixed swapped parameter definitions between !slist and !sdetail commands
Fixed script execution timeout mismatch that caused “Another script is already running” errors when scripts took longer than 30 seconds
Fixed stale execution state cleanup when script execution times out or fails

Added

Rerun button in debug command results to quickly re-execute the same command on the same collectors

Improved

Clarified ambiguous button labels in debug command results — “Copy” split into “Copy Command” and “Copy Output”, “Export” renamed to “Export All”, “Download” renamed to “Download Output”

v1.7.4 — Workspace Switching Bug Fixes

v1.7.4February 2026

This patch release fixes workspace navigation cases where switching views could appear to do nothing, especially when no script tabs were open yet.

Bug Fixes

Fixed switching from API Explorer to Script Editor when no script tabs exist by correctly showing the Script welcome screen
Fixed Collector Sizing workspace switches to consistently restore the most recent tab of the selected workspace when available
Fixed edge cases in view toggling where workspace and active-tab state could fall out of sync
Fixed arrow-key navigation across open tabs so keyboard navigation behaves more reliably
Fixed Save and Save As shortcuts to run only when an active tab is selected
Fixed LogicModule Browser to surface only importable scripted modules (script or batchscript) instead of non-script module variants

Improved

Unified workspace switching behavior across the Actions menu, Command Palette, and keyboard shortcut toggles
Aligned Actions menu and Command Palette options so common tasks are easier to find in either place
