Linting rules for dashboard YAML configurations

kb-dashboard-lint

Linting rules for Kibana dashboard YAML configurations.

Overview

This package provides a configurable linting system that flags potentially problematic dashboard configurations based on best practices and style guidelines. It works with validated Pydantic models from kb-dashboard-core.

Installation

pip install kb-dashboard-lint

Or with uv:

uv add kb-dashboard-lint

Usage

CLI

# Check dashboards in a directory
kb-dashboard-lint check --input-dir ./inputs

# Check a single file
kb-dashboard-lint check --input-file dashboard.yaml

# Use custom configuration
kb-dashboard-lint check --config .dashboard-lint.yaml

# Only fail on errors (not warnings)
kb-dashboard-lint check --severity-threshold error

Programmatic API

from kb_dashboard_lint import check_dashboards
from kb_dashboard_core import load

# Load dashboards
dashboards = load('inputs/')

# Run linting
violations = check_dashboards(dashboards)

for violation in violations:
    print(f"{violation.severity}: {violation.rule_id} - {violation.message}")
