CHANGELOG - Storage Saturation Report Component
===============================================

Version 1.0.3 - January 31, 2026
----------------------------------
- PDF export: switched to client-side jsPDF + html2canvas (no Nagios XI Chromium/command pipeline).
  Export PDF now generates the PDF in the browser and triggers download; fallback to window.print()
  if jsPDF or html2canvas unavailable. Works regardless of XI command processor or Chromium.
- Progress bar: restored color styles (green/amber/red) in the minimal export document so the
  "percent used" bar displays correctly when that HTML is used (e.g. client-side capture, print).
- Vendor: optional jspdf.umd.min.js in scripts/vendor/ for PDF; CDN fallback. See scripts/vendor/README.txt.

Version 1.0.2 - January 31, 2026
----------------------------------
- My Reports (XI core): myreports.php parent-frame innerHTML guarded with null checks to avoid
  "Cannot set properties of undefined" when parent lacks #leftnav (e.g. from component report).
- Export Image: load html2canvas from component scripts/vendor/html2canvas.min.js first, then CDN
  fallback; avoids tracking prevention blocking when vendor file is present. See scripts/vendor/README.txt.
- Docs: double slash in PDF download URL (nagiosxi//reports/managereports.php) documented as known
  XI core URL-building issue; fix belongs in includes/js/reports.js (not in this component).
- Export URL: strip CR/LF from Chromium report URL so stored/passed URL is one contiguous string
  (avoids link being split so only first segment is clickable). XI core: fail_download() now outputs
  URL in a single <a href="..."> so the full URL is one clickable link.
- PDF/JPG export: build Chromium URL with get_localhost_url() so Chromium fetches report via
  localhost; fixes ERR_ACCESS_DENIED when server cannot reach external IP.
- UI: report actions (settings, star, Export PDF, Export Image) aligned right (justify-content:
  flex-end) to match Nagios XI report pattern.
- Options drawer: added neptune-drawer-options block (options-drawer-header + reportoptionpicker)
  so Report Options gear opens drawer with content; minimal copy "No additional options for this report."
- Report options: added Schedule and Email links (schedulereport.php?name=... and &sendonce=1) so
  full report-options row matches XI (settings, star, Schedule, Email, Export PDF, Export Image).
- Report component: full report URL passed to get_add_myreport_html() so Schedule, Email Report,
  and Add to My Reports open/schedule the correct report page.
- UI: all report actions (settings, star, Schedule, Email, Export PDF, Export Image) in one
  well.report-options.form-inline row; Export PDF/Image moved from header into well; alignment
  matches Nagios XI report examples (e.g. Availability Summary).
- UI: removed duplicate report header (title/subtitle/date). Header shown once in page; getreport
  fragment for AJAX returns only table; header included only in export (PDF) document.
- UI: numeric columns (DISK SPACE USED, DISK SPACE AVAILABLE, PERCENT USED) right-aligned to match
  Nagios XI report examples (e.g. Availability Summary).
- Export/print aligned with Nagios XI built-in report pattern:
  * Single entry point (index.php) with mode routing: default, mode=getreport, mode=submitpdf/submitjpg
  * mode=getreport: server-side HTML report body only (for AJAX and Chromium PDF/JPG export)
  * mode=submitpdf/submitjpg: uses utils-reports-export submit_report() and COMMAND_DOWNLOAD_REPORT
  * Report container (#report) loaded via AJAX from index.php?mode=getreport
  * PDF export uses reports.js submit_report() for async command polling and download
  * reportexportlinks and get_add_myreport_html() for Add to My Reports / Schedule / Email Report
- Removed client-side window.print() and html2canvas-only PDF path in favor of XI report export
- Export Image (PNG) retained as optional client-side fallback via html2canvas

Version 1.0.1 - January 30, 2026
----------------------------------
- Perfdata: support quoted labels with special characters 
-- (e.g. 'C:\_Label:__Serial_Number_2cxxxxxx'=91445.6016MB;111560;132477;0;139450)
- Perfdata: when multiple metrics in one service, show the most saturated.
-- (e.g. 'C:\_Label:__Serial_Number_2cxxxxxx'=91445.6016MB;111560;132477;0;139450 'D:\_Label:__Serial_Number_2cxxxxxx'=138500.6016MB;111560;132477;0;139450)
- Caption column uses perfdata volume label when present
- UI: Neptune theme aware with fallbacks for dark/light as per Nagios Developer Standards
- UI: table class follows is_neptune()
- UI: reduced inline styles; spacing moved to CSS classes to conform with Nagios Developer Standards

Version 1.0.0 - January 18, 2026
----------------------------------
- Display services with trackvolume custom variable enabled
- Filter services by trackvolume custom variable
- Parse disk usage from perfdata (check_local_disk and NCPA formats)
- Report-style display with columns:
  * DISPLAY NAME (host name)
  * CAPTION (service description)
  * DISK SPACE USED (formatted)
  * DISK SPACE AVAILABLE (formatted with color coding)
  * PERCENT USED (with progress bar)
- Sort by available space (ascending - most critical first)
- Color coding for available space:
  * Red (< 5 GB): Critical
  * Yellow (< 50 GB): Warning
  * Green (>= 50 GB): Safe
- Progress bar color coding:
  * Red (>= 95%): Critical
  * Orange (>= 85%): Warning
  * Yellow (>= 70%): Info
  * Green (< 70%): Safe
- Export functionality (PDF/JPG) using Python
- Proper Nagios XI component patterns:
  * Standard initialization sequence
  * Security best practices (grab_request_var, escapeshellarg)
  * XML API for custom variables (template inheritance)
  * Proper error handling
  * CCM theme matching
