MikroTik RouterOS monitoring for CheckMK

Monitors MikroTik RouterOS devices via the RouterOS API (v2, port 8729/SSL or 8728) or the RESTful API. Provides checks for:

• System health, fans, and temperature sensors
• Power supply units (per-PSU voltage, current, and wattage)
• BGP and OSPF neighbors
• VRRP status
• IPsec tunnels
• Firewall rules (with optional disabled-rule visibility)
• File age monitoring
• RouterOS board info and version enforcement
• License expiration (CHR)

v4.0.0 — CheckMK 2.4/2.5 compatibility update

This release is a full API migration. The cmk.gui.plugins.wato interface was removed in CheckMK 2.5; the plugin now uses cmk.rulesets.v1 and cmk.server_side_calls.v1. Existing rules are migrated automatically on install — no manual reconfiguration needed.

The SSL connection options have been consolidated into a single dropdown (SSL/verify, SSL/skip cert, Plain TCP) to prevent conflicting settings. Power monitoring now creates one service per PSU instead of a single aggregated service, fixing doubled readings on dual-PSU devices. Password store integration has been fixed to handle CheckMK's binary store format correctly.

Tested on CheckMK 2.4. Compatibility with CheckMK 2.5 follows from the API migration but has not yet been verified in production.
