CloudMonitor, Log Service, and Cost Management

Understanding how to monitor your Alibaba Cloud resources and manage costs is just as important as knowing how to build with them. This lesson covers CloudMonitor, Log Service, ActionTrail, and billing tools.

CloudMonitor

CloudMonitor is Alibaba Cloud's primary monitoring service. It collects metrics from your cloud resources and enables alerting.

Metrics

CloudMonitor automatically collects metrics from Alibaba Cloud services:

Service	Example Metrics
ECS	CPU utilisation, memory usage, disk I/O, network traffic
RDS	Connections, IOPS, storage usage, replication delay
OSS	Request count, bandwidth, error rate
SLB	Active connections, request rate, latency
Function Compute	Invocations, duration, errors

Alert Rules

Define alert rules to notify you when metrics exceed thresholds:

• Threshold alerts — trigger when a metric exceeds a value for a specified duration
• Contact groups — define who receives alerts (email, SMS, DingTalk)
• Escalation — automatically escalate if alerts are not acknowledged

Example alert: If ECS CPU utilisation exceeds 80% for 5 consecutive minutes, send an alert to the Operations team via DingTalk.
