Data Sources and Index Patterns - Wazuh Dashboard Plugins

Overview

Wazuh Dashboard Plugins organize security data into specialized index patterns optimized for different types of events and states. This structured approach enables efficient querying, visualization, and analysis of security telemetry.

Index Pattern Architecture

Data is organized into three primary categories:

Events

Real-time security events with timestamps, categorized by event type

States

Current state snapshots of system inventories, vulnerabilities, and configurations

Operational

Monitoring data and statistics for agents and servers

Index Pattern Types

From constants.ts:19-108:

Index Pattern Initialization

The server plugin registers health checks to ensure all index patterns exist during startup.

Health Check Registration

From plugins/main/server/plugin.ts:

core.healthCheck.register(
  initializationTaskCreatorIndexPattern({
    services: plugins.wazuhCore,
    taskName: HEALTH_CHECK_TASK_INDEX_PATTERN_VULNERABILITIES_STATES,
    indexPatternID: WAZUH_VULNERABILITIES_PATTERN,
    options: {
      fieldsNoIndices: IndexPatternVulnerabilitiesKnownFields,
    },
  })
);

Index Pattern Options

taskName

string

required

Unique identifier for the health check task

indexPatternID

string

required

The index pattern string (e.g., wazuh-events*)

options.savedObjectOverwrite

object

Saved object properties to set/override

options.hasTimeFieldName

boolean

default:"false"

Whether the index pattern has a time field

options.fieldsNoIndices

array

Known field definitions when indices don’t exist yet

options.checkDefaultIndexPattern

boolean

default:"false"

Whether this should be the default index pattern

Known Fields

Known fields are pre-defined field mappings stored in JSON files under common/known-fields/. These allow index patterns to be created before any data is indexed. Example: common/known-fields/events.json

[
  {
    "name": "@timestamp",
    "type": "date",
    "searchable": true,
    "aggregatable": true
  },
  {
    "name": "wazuh.agent.id",
    "type": "string",
    "searchable": true,
    "aggregatable": true
  },
  // ... more fields
]

Data Flow

Event Pipeline

Agent Collection

Wazuh agents collect security events and system state data

Manager Processing

Wazuh Manager processes, enriches, and categorizes events

Indexing

Events are indexed into OpenSearch with appropriate index patterns

Index Pattern Matching

Dashboard queries use index patterns to search relevant indices

Visualization

Results are rendered in dashboards and visualizations

Index Naming Convention

wazuh-{category}-{version}-{subcategory}-{date}

Examples:
- wazuh-events-v5-security-2026.03.04
- wazuh-states-vulnerabilities-2026.03.04
- wazuh-monitoring-2026.03.04

Components:

wazuh: Namespace prefix
{category}: events, states, monitoring, statistics
{version}: v5 (for events)
{subcategory}: security, system-activity, vulnerabilities, etc.
{date}: YYYY.MM.DD for daily indices

Sample Data

The plugin provides sample data generation for testing and demonstrations.

Sample Data Categories

From constants.ts:271-475:

export const WAZUH_SAMPLE_DATA_CATEGORIES_TYPE_DATA = {
  [WAZUH_SAMPLE_AGENT_MONITORING]: [
    {
      indexPatternPrefix: WAZUH_SETTING_AGENTS_MONITORING_SAMPLE_PREFIX.indexPatternPrefix,
      dataSet: WAZUH_SETTING_AGENTS_MONITORING_SAMPLE_PREFIX.dataSet,
    },
  ],
  [WAZUH_SAMPLE_ALERTS_CATEGORY_SECURITY]: [
    { syscheck: true },
    { aws: true },
    { azure: true, count: 1000 },
    { office: true },
    { gcp: true },
    { authentication: true },
    { ssh: true },
    { apache: true, count: 2000 },
    { web: true },
    { windows: { service_control_manager: true }, count: 1000 },
    { github: true },
  ].map(item => ({
    ...item,
    indexPatternPrefix: `${WAZUH_SETTING_ALERTS_SAMPLE_PREFIX.indexPatternPrefix}-${WAZUH_SAMPLE_ALERTS_CATEGORY_SECURITY}`,
    dataSet: WAZUH_SETTING_ALERTS_SAMPLE_PREFIX.dataSet,
  })),
  // ... more categories
};

Available Categories:

Agent Monitoring
Security Alerts
Auditing & Policy Monitoring
Threat Detection
File Integrity Monitoring
Security Configuration Assessment
Inventory Agent
Server Statistics
Vulnerabilities

Sample Data Configuration

WAZUH_SAMPLE_ALERTS_DEFAULT_NUMBER_DOCUMENTS

number

default:"1500"

Default number of sample documents to generate

// From constants.ts:167-181
export const WAZUH_SAMPLE_ALERTS_INDEX_SHARDS = 1;
export const WAZUH_SAMPLE_ALERTS_INDEX_REPLICAS = 0;
export const WAZUH_SAMPLE_ALERTS_DEFAULT_NUMBER_DOCUMENTS = 1500;

Query Optimization

Time-Based Filtering

For event index patterns, always apply time range filters:

const timeFilter = {
  range: {
    '@timestamp': {
      gte: 'now-24h',
      lte: 'now',
    },
  },
};

Agent Filtering

Filter by specific agent:

const agentFilter = {
  term: {
    'wazuh.agent.id': '001',
  },
};

Cluster Mode Filtering

For vulnerabilities in cluster mode:

// From constants.ts:34
export const VULNERABILITY_IMPLICIT_CLUSTER_MODE_FILTER = 'wazuh.cluster.name';

const clusterFilter = {
  term: {
    [VULNERABILITY_IMPLICIT_CLUSTER_MODE_FILTER]: 'wazuh-cluster',
  },
};

Field Formats

Specialized field formatting improves data presentation:

Byte Formatting

mapFieldsFormat({
  'file.size': 'bytes',
  'host.memory.free': 'bytes',
  'host.memory.total': 'bytes',
  'host.memory.used': 'bytes',
  'package.size': 'bytes',
  'registry.size': 'bytes',
  'host.network.egress.bytes': 'bytes',
  'host.network.ingress.bytes': 'bytes',
})

Percentage Formatting

mapFieldsFormat({
  'host.memory.usage': 'percent',
})

Integer Formatting

mapFieldsFormat({
  'destination.port': 'integer',
  'source.port': 'integer',
  'process.pid': 'integer',
  'process.parent.pid': 'integer',
})

Index Lifecycle Management

Index patterns use wildcard matching, allowing for index rotation and lifecycle policies without reconfiguration.

Example: Index pattern wazuh-events* matches:

wazuh-events-v5-security-2026.03.01
wazuh-events-v5-security-2026.03.02
wazuh-events-v5-security-2026.03.03
wazuh-events-v5-security-2026.03.04

This enables:

Daily index rotation
Automated retention policies
Hot-warm-cold architecture
Index deletion without breaking dashboards

Configuration

Default Index Pattern

Set the default index pattern for initial searches:

// From plugin.ts:677
options: {
  checkDefaultIndexPattern: true,
}

The events index pattern (wazuh-events*) is typically set as default.

Time Field Configuration

For time-series data:

// From plugin.ts:266-270
options: {
  savedObjectOverwrite: defineTimeFieldNameIfExist('timestamp'),
  hasTimeFieldName: true,
}

Time Filter Settings

Default time range for dashboards:

// From constants.ts:598-601
export const WAZUH_PLUGIN_PLATFORM_SETTING_TIME_FILTER = {
  from: 'now-24h',
  to: 'now',
};
export const PLUGIN_PLATFORM_SETTING_NAME_TIME_FILTER = 'timepicker:timeDefaults';

Best Practices

Use Specific Patterns

Query the most specific index pattern for your use case (e.g., wazuh-events-v5-security* instead of wazuh-events*) for better performance

Apply Time Filters

Always filter by time range on event indices to limit data scanned

Filter Early

Apply agent, cluster, and category filters in the query for index-level filtering

Aggregate Wisely

Use appropriate aggregation intervals and bucket limits
