# Service: icinga-stack

# Description: Installs and configures a full Icinga2 monitoring stack.

# --- OS & Version Configuration ---
|
||||
# This section contains variables that may need to be updated for a new OS release.
|
||||

||||
# Automatically detect the OS codename (e.g., "bookworm", "trixie")
|
||||
# This should work without changes on future Debian versions.

|
||||

# Define the PHP version for the current OS release.
|
||||
# For Debian 12 (Bookworm), this is 8.2.
|
||||
# For a future Debian 13 (Trixie), you would likely change this to "8.3".
