# Checkmk SwissKnife A [Tampermonkey](https://www.tampermonkey.net/) userscript that enhances the Checkmk 2.3.x web interface with quality-of-life improvements for WATO configuration and monitoring views. ## Installation 1. Install the [Tampermonkey](https://www.tampermonkey.net/) browser extension. 2. Install the script from one of these sources: - [**GreasyFork**](https://greasyfork.org/en/scripts/585184-checkmk-swissknife) *(recommended)* - [**Direct install**](https://luigidacunto.com/scripts/checkmk-swissknife/user_script/checkmk_swissknife.user.js) 3. Tampermonkey will detect the `@downloadURL` and prompt for updates automatically. **Compatibility:** Checkmk 2.3.x · Chrome · Firefox · Edge ## Features | Feature | Description | Code function | |---------|-------------|---------------| | **Folder Path Search** | Replaces the folder dropdown with a searchable overlay — type any path segment to filter instantly | `initSelect2Enhanced` | | **Accordion Badge Counts** | Shows inline counters in each accordion header: enabled checkboxes (orange), inherited values (blue), differing values vs folder default (red) | `initAccordionCheckedCounts` | | **Ineffective Rule Highlight** | Replaces the hard-to-spot hyphen icon on ineffective rules with a visible ⚠ badge and amber row border | `highlightIneffectiveRules` | | **Rule Match Status** | Colors each rule row green (match) or dimmed (no match) when a ruleset is opened with host/service context | `highlightRuleMatchStatus` | | **Relevant Only Filter** | Adds a "Relevant only" toggle above the rule list to hide all non-matching and non-highlighted rows | `addRulesetFilterToggle` | | **Extra Column — Host Actions** | Inserts an Extra column in monitoring tables with per-host buttons: Service Discovery, copy FQDN, copy short hostname, copy IP | `addInventoryButtons` | | **Monitor Button in WATO Folder** | Adds a green eye icon next to each active host in WATO folder listings to open its monitoring view in a new tab | `addWatoFolderMonitorButtons` | | **Configure in WATO Menu** | Adds a host-selector dropdown and Open button to the monitoring view menu bar for bulk-opening hosts in WATO | `addViewWatoMenu` | | **Auto-check Foreign Changes** | Automatically ticks the "Activate foreign changes" checkbox on the pending changes page | `tryAutoCheckForeignActivation` | | **Collapse All / Expand All** | Adds two buttons to the menu bar to collapse or expand all accordion sections at once | `addAccordionToggleButtons` | --- ### Folder Path Search Replaces the default WATO folder dropdown with a searchable overlay. Type any segment of the folder path to filter — separators `>`, `›`, and `/` are treated as equivalent. Applies to: rule condition editor (`explicit_conditions_p_folder_path`) and monitoring view folder filter (`wato_folder`). --- ### Accordion Badge Counts Displays inline counters in each accordion section header on host edit pages: | Badge | Meaning | |-------|---------| | **orange `(N)`** | N checkboxes enabled in this section | | **blue `↑N`** | N values inherited from a parent folder | | **red `≠N`** | N values that differ from the folder default *(bulk edit only)* | Applies to: `edit_host`, `bulkedit`, `editfolder`. --- ### Ineffective Rule Highlight Replaces the low-visibility hyphen icon on ineffective rules with a prominent **`⚠ ineffective`** badge and adds an amber left border to the row. Applies to: `mode=edit_ruleset`. --- ### Rule Match Status Highlight When a ruleset is opened in context (URL contains `host=` and/or `service=`), colors each rule row: - **Green + `✓ match`** — rule applies to the given host/service - **Dimmed + `✗ no match`** — rule does not apply Applies to: `mode=edit_ruleset` with host/service context. --- ### Ruleset Filter Toggle After match/ineffective highlighting runs, a **"Relevant only"** button appears above the rule list. Clicking it hides all non-highlighted rows and empty folders, leaving only the rules that matter for the current context. Applies to: `mode=edit_ruleset` (when at least one highlighted row exists). --- ### Extra Column with Host Actions Adds a dedicated **Extra** column before the Host column in all monitoring view tables. Each row gets up to four icon buttons: | Button | Color | Action | |--------|-------|--------| | Screen icon | Amber | Opens **Service Discovery** for the host in a new tab | | Clipboard icon | Blue | Copies the full FQDN to clipboard | | Clipboard icon | Purple | Copies the short hostname (first label) to clipboard | | Clipboard icon | Green | Copies the host **IP address** to clipboard *(shown only when available)* | The IP address is read from the tooltip Checkmk places on the hostname cell. Clicking any clipboard button briefly turns it green to confirm the copy. Applies to: `view.py` host and service views. --- ### Monitor Button on WATO Folder Pages Adds a green eye icon next to each active (non-disabled) host in WATO folder listings, opening the host's monitoring view in a new tab. A summary badge on the section header shows monitored vs disabled host counts. Applies to: `wato.py?mode=folder`. --- ### "Configure in WATO" Menu Adds a **Select hosts (N)** dropdown and an **Open** button to the monitoring view menu bar. Select a page of hosts, then click **Open** — WATO opens in a new tab with exactly those hosts pre-filtered via regex search, ready for bulk configuration. - Up to 50 hosts per page (keeps URLs within safe length limits) - Deduplicates hostnames automatically (useful on service views where hosts repeat) - **Open** button is disabled (gray) until a page is selected; turns blue when active; resets after opening - Only visible for users with WATO configuration access Applies to: `view.py` (admin/configuration role required). --- ### Auto-check "Activate Foreign Changes" On the **Activate pending changes** page, automatically checks the *Activate foreign changes* checkbox as soon as the page is ready, so you never have to remember to tick it manually before activating. Applies to: `wato.py?mode=changelog` (with or without sidebar). --- ### Collapse All / Expand All Adds two buttons to the top menu bar on any page with expandable sections: | Button | Color | Action | |--------|-------|--------| | **Collapse All** | Orange | Collapses all open accordion sections at once | | **Expand All** | Green | Expands all collapsed accordion sections at once | Works on both host-edit pages (accordion sections are `table.nform` elements) and ruleset pages (accordion sections are `div.foldable` elements). Applies to: `edit_host`, `bulkedit`, `editfolder`, `edit_ruleset` (with or without sidebar). ## How it works The script injects enhancements at page load and re-applies them on SPA navigation (Checkmk reloads content inside an `
