Description

METHOD AND SYSTEM FOR MANAGING LOAD OF ALARMS IN A NETWORK MANAGEMENT SYSTEM FIELD OF THE INVENTION [0001] The present invention generally relates to wireless communication networks, and more particularly relates to a method and system for managing load of alarms in the networks. BACKGROUND OF THE INVENTION [0002] Network Management Systems (NMS) are software applications or platforms designed to monitor, control, and manage computer networks. NMS solutions play a crucial role in maintaining network performance, reliability, and security. NMS provides a centralized interface for network administrators to efficiently manage and troubleshoot network devices, services, and resources. [0003] NMS tools monitor network devices and services for fault conditions and generate alarms or notifications when issues are detected. Alarms can include events such as device failures, connectivity problems, threshold violations, security breaches, or performance degradation. [0004] By effectively managing network traffic and alarms, NMS tools help network administrators monitor network health, troubleshoot issues, and maintain a stable and reliable network infrastructure. These functionalities contribute to efficient network operations and better end-user experiences. [0005] In the Network Management System, there are several possible events of sudden and significant increase in the number of alarms or events being generated within a short period, that is known as burst case. It could be due to various factors such as network failures, equipment malfunctions, security incidents, or sudden spikes in network traffic. During a burst case, the NMS experiences a surge in the volume of alarms, which can potentially overwhelm the system and its components responsible for processing and managing those alarms. [0006] The existing burst mechanism may not have been designed to handle sudden and significant increases in alarm volumes. As a result, the NMS may struggle to scale up its processing capabilities to accommodate the burst, leading to performance degradation or unresponsiveness. [0007] Additionally, if the existing burst mechanism heavily relies on manual intervention for managing the burst, it can introduce delays and increase the risk of errors. Manual processes may not be able to keep up with the rapid influx of alarms, potentially leading to extended resolution times and suboptimal handling of the burst situation. [0008] Therefore, there is a need for an advancement of a system and method that can overcome at least one of the above shortcomings, particularly for managing load of alarms in the network management system. BRIEF SUMMARY OF THE INVENTION [0009] One or more embodiments of the present disclosure provide a method and system for managing load of alarms in a Network Management Systems (NMS). [0010] In one aspect of the present invention, a method for managing load of alarms in a Network Management Systems (NMS) is disclosed. The method includes the step of fetching, by one or more processors, data pertaining to a total count of alarms stored in a database. The method includes the step of comparing, by the one or more processors, the total count of alarms with a first predefined threshold and a second predefined threshold, respectively. The method includes the step of performing, by the one or more processors, one or more tasks to manage the load of alarms in the NMS based on comparison of the total count of alarms with the first predefined threshold and the second predefined threshold, respectively. [0011] In one embodiment, the one or more tasks performed by the one or more processors, includes at least one of disabling, consumption of subsequent one or more alarms until a pre-defined time period is completed, in response to detecting, the total count of alarms being greater than the first predefined threshold. The one or more tasks includes enabling, consumption of subsequent one or more alarms until the pre-defined time period is completed, in response to detecting, the total count of alarms being lower than the second predefined threshold. The one or more tasks includes enabling, consumption of subsequent one or more alarms until the pre-defined time period is completed, in response to detecting, the total count of alarms being lower than the first predefined threshold and greater than the second predefined threshold, and the total count of the alarms increases until the total count of alarms reaches the first predefined threshold. The one or more tasks includes disabling, consumption of subsequent one or more alarms until the pre-defined time period is completed, in response to detecting, the total count of alarms being lower than the first predefined threshold and greater than the second predefined threshold, and the total count of the alarms at least one of, remains constant and decreases. [0012] In another embodiment, the one or more processors fetches details of the alarm by retrieving an alarm identifier
