Repository Sync

The repository is automatically synchronized on CheckMK servers using a Python-managed, systemd timer-based model:

# Install auto-sync (systemd timer-based, with fallback to cron on systems without systemd)
python3 installation/install-checkmk-sync.py --git-interval 30

Active Model:

Architecture: Python orchestration (sync_update/auto_git_sync.py) with minimal Bash runtime wrapper
Systemd Mode: Timer (auto-git-sync.timer) + oneshot service (auto-git-sync.service)
Sync Logic: git fetch origin main → git reset --hard origin/main → git clean -fd
Cron Fallback: On systems without systemd (OpenWrt, NethSecurity 8), sync runs every minute via cron
Log: /var/log/auto-git-sync.log

Important: /opt/checkmk-tools/ is a read-only deploy clone managed by auto-sync. Never edit files directly in /opt/checkmk-tools/ — all changes will be overwritten on the next sync cycle. Real editing must occur in your editable source workspace, then committed and pushed to the repository. The auto-sync timer will automatically pull updates.

Ydea Toolkit

Directory: Ydea-Toolkit/

Integration between CheckMK and the Ydea helpdesk system for automatic ticket creation from monitoring events, plus a broad set of Ydea REST API exploration/test scripts (each with both a .py implementation and a .sh wrapper) used to reverse-engineer SLA, contract, and ticket endpoints.

Structure:

full/ — Integration scripts + API exploration/test scripts
config/ — Configuration files (credentials.sh.template, premium-mon-config.json)
doc/ — Documentation (including README-CHECKMK-INTEGRATION.md)

Features

Automatic ticket creation from CheckMK PROBLEM/RECOVERY events
SLA discovery from customer contracts
Ticket deduplication and state tracking
Health monitor for integration status
Correlator to link CheckMK notifications back to existing Ydea tickets

Key Scripts

Script	Description
`ydea_monitoring_integration.py`	Core CheckMK-Ydea integration
`install_ydea_checkmk_integration.py`	Automated installation
`ydea_health_monitor.py`	Integration health monitoring
`ydea_ticket_monitor.py`	Open ticket monitor
`ydea_discover_sla_ids.py`	Automatic SLA discovery from contracts

`ydea_common.py`	Shared API client/helpers
`ydea_templates.py`	Ticket message templates
`ydea-toolkit.py`	Ydea API master toolkit

The remaining explore_*, search_*, get_*, test_*, and analyze_* scripts (with matching .sh wrappers) are ad-hoc tools for exploring the Ydea API surface (anagrafica, SLA, tickets, contracts) — see Ydea-Toolkit/doc/ for details.

Nethesis Branding

Directory: nethesis-brand/

CSS and SVG assets to apply Nethesis visual identity to the CheckMK web interface (Facelift theme).

Files:

theme.css — CSS overrides for colors and fonts
checkmk_logo.svg — Login page logo (290px)
icon_checkmk_logo.svg — Sidebar icon (40px)
icon_checkmk_logo_min.svg — Sidebar icon (28px)

Deploy:

./deploy-nethesis-brand.sh

Installation

Requirements

Linux (all platforms):

Python 3.6+
CheckMK Agent installed
curl (for some tools)

Windows:

PowerShell 5.1+
CheckMK Agent for Windows

Deploy a Check Script

# Clone the repository
git clone https://github.com/Coverup20/checkmk-tools.git /opt/checkmk-tools

# Copy the desired script to the local checks directory (no extension)
cp /opt/checkmk-tools/script-check-ns7/full/check_dovecot_status.py \
   /usr/lib/check_mk_agent/local/check_dovecot_status
chmod +x /usr/lib/check_mk_agent/local/check_dovecot_status

# Verify output
/usr/lib/check_mk_agent/local/check_dovecot_status

Scripts are deployed without the .py extension so CheckMK executes them directly.

Auto-Sync Setup

To keep scripts automatically updated on a server:

python3 /opt/checkmk-tools/script-tools/full/installation/install-checkmk-sync.py --git-interval 60

Notification Script Installation

# On CheckMK server (as root)
git clone https://github.com/Coverup20/checkmk-tools.git /tmp/checkmk-tools
cp /tmp/checkmk-tools/script-notify-checkmk/full/mail_realip \
   /omd/sites/SITENAME/local/share/check_mk/notifications/
chmod +x /omd/sites/SITENAME/local/share/check_mk/notifications/mail_realip

# Check <service> status

import subprocess

SERVICE = "ServiceName"

## Utils

def run(cmd):
    try:
        p = subprocess.run(cmd, capture_output=True, text=True, timeout=10)
        return p.returncode, p.stdout, p.stderr
    except Exception as e:
        return 1, "", str(e)

## Check

def check():
    rc, out, err = run(["systemctl", "is-active", "myservice"])
    if rc != 0:
        print(f"2 {SERVICE} - CRITICAL: service not running")
        return
    print(f"0 {SERVICE} - OK: running")

check()

Rules:

No classes, no if __name__ == "__main__" — call the function directly at module level
No type hints, no docstrings on obvious functions
subprocess.run with capture_output=True, text=True — never shell=True
CheckMK output format: <STATE> <SERVICE> - <message>
Script version in VERSION = "x.y.z" variable at module level

Naming Convention

Check scripts: check_<name>.py
Deployed name (no extension): check_<name>
CheckMK service name: ServiceName (matches the SERVICE constant)

Auto-Sync System

The repository uses an automatic synchronization system on CheckMK servers:

Local Editable Workspace
    ↓ [git commit & push]
GitHub (Coverup20/checkmk-tools)
    ↓ [auto-git-sync timer - configurable interval, default 30s]
/opt/checkmk-tools/ (read-only deploy clone on servers)
    ↓ [execute scripts from synchronized repo]
Production

Sync Model:

Timer: auto-git-sync.timer runs on a configurable schedule (default 30 seconds)
Service: auto-git-sync.service (Type=oneshot) is triggered by the timer
Runtime: Minimal Bash wrapper (/usr/local/bin/checkmk-git-sync.sh) generated during installation
Behavior: Fetch origin/main, reset hard, clean working directory
Logging: All sync operations logged to /var/log/auto-git-sync.log

Check Sync Status

# Timer status
systemctl status auto-git-sync.timer

# Service status
systemctl status auto-git-sync.service

# View recent logs
journalctl -u auto-git-sync.service -f
tail -f /var/log/auto-git-sync.log

# List scheduled timer runs
systemctl list-timers auto-git-sync.timer

Manual Sync (Force Immediate Pull)

# Trigger sync immediately (do NOT edit /opt/checkmk-tools directly)
systemctl start auto-git-sync.service
