When dealing with alarms for different resources, such as server performance, hardware health, log status, log keywords, process performance, and database performance, it enables the accumulation of operational and maintenance solutions. When a fault occurs, the system can automatically recommend historical similar scenarios or alarms and reuse historical solutions.

06 Report Management

Provides a variety of scenario-based reports, including real-time reports, TOPN reports, traffic reports, daily and weekly reports, custom reports, host performance reports (identifying zombie machines), graphical reports, inspection reports, and availability reports.

It also supports report export and sharing operations, as well as self-subscription and proxy subscription, with scheduled report delivery to email addresses.

Asset Management Capabilities: Fine-Grained Management and Resource Visualization

The asset management capabilities of the Lerwee operational and maintenance agent mainly rely on LeWei CMDB, which focuses on fine-grained model management, resource visualization, event integration, and compliance automation. It aims to provide enterprises with a more powerful, flexible, and intelligent configuration management database solution, significantly improving IT operational and maintenance efficiency and management levels.

Model Management: Fine Control and Flexible Expansion

01 Introduction of Parent Models and Relationship Openness

The introduction of the parent model concept is used to define common attributes and relationships, standardize configuration item classification, achieve inheritance and extension, and simplify data management, optimizing the model hierarchy structure.

At the same time, parent models are open to relationship-based references and enumerations, enabling cross-level topological associations and greatly enhancing the inter-model correlation and data reuse capabilities. Enumerated lists are used to restrict the value ranges of certain attributes, ensuring the规范性 (standardization) of child model data.

02 Enhanced Model Relationships

Supports the establishment of relationships between a model and itself, allowing direct relationships between different instances of the same model. This simplifies model design while meeting more complex topological structure expressions (e.g., device cascading).

03 Global and Local Attributes

Global attributes: Define model-level universal attributes applicable to all instances of the model, ensuring consistency and standardization of core data. For example, using a global attribute to define the “operational and maintenance responsible person” field for all servers.

Local attributes: Support dynamically adding and managing attributes in specific model instances or business scenarios, achieving fine-grained and scenario-based attribute management to meet complex and changing business needs. For example, using a local attribute to define the “temporary responsible person” field for development and testing servers, which is only valid locally.

04 Enhanced Attribute Types

Supports IP address segment attributes for more precise management of network resources.

Supports phone number attributes to完善 (complete) basic information management.

05 Optimized Data Pushing

Supports pushing structured array data to separate instances, enhancing the flexibility and integration capabilities of data processing.

06 Configurable Change Records

Users can customize change tracking strategies for key attributes (e.g., contracts, maintenance, responsible persons, affiliated businesses), making audits clearer.

Data Center View: Panoramic Visualization and Intelligent Management

01 Planar Layout Display

Supports displaying data center planar layout diagrams, providing a more intuitive and realistic overview of the physical environment.

Meanwhile, in the U-position overview interface, empty U-positions can directly bind devices such as servers, network devices, and storage. It also supports manual dragging to reorder U-position abnormal devices, making device management smoother.

02 Configurable U-Position Conditions

Allows configuring U-position condition rules for device placement (e.g., must be in the same U-position, prohibited from being in the same U-position), improving the standardization and accuracy of cabinet space planning.

03 Customizable Global Styles

Supports customizing global font sizes, font colors, and cabinet capacity percentage display colors, making the visualization effects more in line with user habits and preferences.

04 Device Filtering and Drilling

The total device list supports filtering by model to quickly locate specific types of devices. At the same time, the device count display supports drilling down to view specific device lists, making analysis more convenient.

Event Subscription: Multi-Channel Push and Efficient Integration
