In the field of IT operation and maintenance management, Lerwee NMS and SolarWinds NPM, as two professional network management systems, each have distinct features in specific function implementation and focus areas. However, both possess comprehensive technical capabilities in core functional modules, capable of meeting enterprise-level network management requirements. The following comparison will be conducted from three dimensions: Report Management, Alarm Management, and PerfStack Performance Analysis.

I. Report Management

Both systems offer powerful reporting functions, supporting custom reports and automatic push tasks to meet enterprises’ needs for data statistics and archiving in daily operation and maintenance. Lerwee NMS provides more diversified options in statistical granularity, subscription methods, and report scenario relevance, while SolarWinds NPM has a slight advantage in the number of traditional templates and report usability.

Lerwee NMS demonstrates unique strengths in report flexibility and built-in richness:

• Rich built-in report types: The product comes with various report types such as real-time reports, traffic reports, daily/weekly reports, inspection reports, custom reports, availability reports, graph reports, host performance reports, and TOPN reports. It has high alignment with operation and maintenance scenarios and strong out-of-the-box usability.

• Flexible multi-dimensional statistics: Supports real-time statistics on multiple monitoring objects and performance indicators. It allows users to customize queries by different time granularities such as hour, day, and month, providing a more detailed data perspective.
• Diverse subscription modes: Offers report subscription functionality, including personal subscriptions and agent subscriptions. Subscription cycles can be set by different granularities such as day, week, and month.

SolarWinds NPM includes a wealth of built-in traditional report templates, which can quickly cover most standardized report scenarios. Meanwhile, its “Report Writer” tool is highly tool-oriented, enabling users to generate personalized reports through mouse operations without the need to write complex database query statements.

II. Alarm Management

Both systems are equipped with comprehensive alarm mechanisms, supporting alarm escalation and multiple notification methods (such as email and SMS). They can suppress alarm storms by defining device dependency relationships, effectively reducing operation and maintenance noise.

A notable feature of Lerwee NMS is its in-depth expansion in intelligent alarm analysis and fault location through associating knowledge, indicators, and topology. It provides operation and maintenance personnel with stronger auxiliary analysis capabilities, effectively improving the efficiency of fault location.

• Alarm and knowledge association: Supports associating alarms with a solution knowledge base. Operation and maintenance personnel can directly view relevant solutions when handling alarms, accelerating the troubleshooting process and embodying the concept of “alarm equals handling”.

• In-depth correlation analysis: Supports historical trend analysis of alarm-related indicators and associated topology mapping. When an alarm occurs, administrators can not only view the current status but also trace the historical changes of relevant indicators. Combined with topology diagrams, they can intuitively analyze the scope of fault impact, which is crucial for quickly locating root causes and assessing impacts.
• Flexible alarm ignoring mechanism: Allows setting specific “ignorance periods” for non-critical alarms. During the ignorance period, no notifications will be generated for such alarms, a function that can accurately reduce unnecessary interference.

SolarWinds NPM’s alarm function is relatively comprehensive. It supports defining device dependency relationships to achieve cascading device alarm storm suppression. Its automatic alarm escalation mechanism and diverse notification modes (including voice reading and Syslog) have been tested by the market and feature high reliability.

III. PerfStack Performance Analysis

Both systems possess powerful performance data analysis capabilities. They support aggregating performance indicators from different devices and applications into a unified view for cross-entity and cross-time period correlation comparison analysis, greatly facilitating the troubleshooting of performance bottlenecks.

Lerwee NMS offers robust unified indicator query and multi-indicator combination comparison:

• Unified indicator query: Provides a unified entrance for indicator query, displaying data in both text and trend chart formats to meet viewing needs in different scenarios.
• Multi-indicator combination comparison: Supports combining, comparing, and viewing multiple indicators from different monitoring objects on the same time axis (X-axis). Even if these indicators have different units, the system can intelligently coordinate the display, making it easy to discover potential correlations.

SolarWinds NPM’s PerfStack function supports combining and comparing different indicators through drag-and-drop operations. The operation is intuitive, enabling managers to effectively determine which link (network, application, virtualization, etc.) a fault occurs in.

Summary

Overall, both Lerwee NMS and SolarWinds NPM are powerful network management software. Lerwee NMS exhibits distinct characteristics aligned with modern and intelligent operation and maintenance needs, excelling in the depth of alarm management (knowledge association and correlation analysis) and the flexibility of report functions (multi-granularity statistics and diverse subscriptions). It can be said that while providing stable and reliable monitoring capabilities, Lerwee NMS is committed to enhancing data relevance and analyzability to deliver more efficient decision support for operation and maintenance teams. As a fully functional and mature product, SolarWinds has traditional advantages in report usability and interactive analysis.
