Domain Detection - DNS Server Monitoring

Designed to monitor the response performance and time of domain servers (DNS), aiming to ensure network connection quality and prevent connection issues caused by DNS response delays. Supports measuring the response time to multiple DNS hosts for the same domain name.


Core Monitoring Objectives
➢ Real-time detection and analysis: Regularly monitor the DNS response time to ensure it meets the normal response time standards, thus maintaining network connection quality.
➢ Performance comparison: Compare the response times of multiple DNS hosts for the same domain name.
➢ Alert mechanism: When the response time exceeds the preset alert threshold, the system will automatically issue an alert to ensure timely handling of potential issues.
➢ Performance analysis: Produce weekly performance analysis charts, store long-term data, and generate alert analysis charts based on the collected data.


Monitoring System Specifications
➢ Detection objective: Regularly monitor the DNS response time to ensure it is within the normal range.
➢ Monitoring target: Focus on whether the DNS response time exceeds the set threshold.
➢ Alert conditions: Set alert conditions based on response time, frequency, and duration.
➢ Real-time information: Provide real-time data and alert release status.
➢ Information collection: Collect and record messages, data, and the time points of alert release and cancellation.
➢ Emergency handling: Once an alert is triggered, it will be immediately notified and the preset emergency handling procedures will be executed.


Alert Thresholds
The WATCHDOG system will issue an alert notification when encountering the following two thresholds:
➢ Unable to connect to DNS or fail to obtain IP.
➢ DNS response time exceeds the set timeout threshold.
