Alerta
Alerta is an open-source, distributed monitoring system. It is used to consolidate and deduplicate alerts from multiple sources, providing a single pane of glass for operations and engineering teams.
Overview
Alerta collects, groups, and manages alerts received from various monitoring tools, application performance monitoring (APM) systems, and infrastructure monitoring platforms. It de-duplicates alerts based on a configurable set of attributes, reducing noise and allowing teams to focus on critical issues. Alerta provides a web-based user interface for managing and triaging alerts, and supports integrations with ticketing systems, chat platforms, and other operational tools.
Key Features
- Alert Aggregation: Consolidates alerts from diverse monitoring sources.
- Deduplication: Reduces alert noise by automatically grouping similar alerts.
- Web UI: Provides a user-friendly interface for viewing, triaging, and managing alerts.
- API: Offers a RESTful API for programmatic interaction with the system.
- Integrations: Supports integrations with various systems including ticketing systems (e.g., Jira, ServiceNow), chat platforms (e.g., Slack, Microsoft Teams), and notification services.
- Correlation: Supports the ability to correlate alerts based on pre-defined rules, improving incident investigation.
- Role-Based Access Control (RBAC): Restricts access to alerts and system functionality based on user roles and permissions.
- Alert History: Maintains a historical record of all alerts and their status changes.
- Flexible Alert Schema: Allows for customization of alert attributes to accommodate diverse monitoring data.
Architecture
Alerta typically consists of the following components:
- Alert API: Accepts alert data from monitoring systems.
- Alerta Server: Processes, stores, and manages alerts.
- Alerta Web UI: Provides a web-based interface for users to interact with the system.
- Database: Stores alert data, configuration, and user information (typically MongoDB).
- Plugins: Extend Alerta functionality by integrating with other systems.
Use Cases
Alerta is commonly used in the following scenarios:
- Centralized Alert Management: Providing a single platform for managing alerts from multiple monitoring systems.
- Incident Response: Facilitating faster incident identification, triage, and resolution.
- DevOps Monitoring: Integrating with CI/CD pipelines and monitoring tools to improve application reliability.
- Site Reliability Engineering (SRE): Enabling SRE teams to proactively monitor and manage system health.
- Cloud Monitoring: Aggregating alerts from cloud infrastructure and services.
