Method for managing network failure in cloud environment and network failure management system

A network fault management system for a cloud environment comprising:

• testing tools processor configured to measure a performance of a target server and output a measurement result;
• a fault management processor configured to receive and analyze the measurement result output by the testing tools processor, determine a threshold and a policy for a target host based on the analyzed measurement result, and output a determination result;
• and monitoring tools processor configured to set a monitoring policy of the target host based on the determination result output by the fault management processor,
• wherein the fault management processor includes a testing tools gateway configured to ask the testing tools processor to measure the performance of the target server and receive the performance measurement result;
• an evaluator processor configured to determine the threshold and the policy for the target host based on the measurement result and a current state of the target server;
• a monitoring tools gateway configured to transmit templated information including the threshold and the policy to the monitoring tools processor;
• and a plugin manager processor configured to transmit the performance measurement result of the target server received from the testing tools gateway to the evaluator processor, and receive the threshold and the policy for the target host from the evaluator processor to generate the templated information including the threshold and the policy and transmit the templated information to the monitoring tools gateway,
• wherein the evaluator processor calculates the threshold based on a machine learning-based calculation method,
• wherein the monitoring tools processor is implemented based on Zabbix, the templated information includes an item, a threshold trigger, and an action, and the monitoring tools processor sets and updates a target host to be monitored based on Zabbix API and scripts, and links the templated information to the target host.
