Create an availability monitoring task

Based on availability monitoring, CloudMonitor helps you locate issues when a local or remote service has no response. CloudMonitor can send an alert notification to you if the local or remote service fails to respond within a specified timeout period or returns an error status code. In this way, you can efficiently check response conditions of local or remote paths and ports.
