Alibaba Cloud Application Load Balancer (ALB) Monitoring Integration
Site24x7 offers complete observability into Alibaba Cloud Application Load Balancer (ALB), allowing you to monitor traffic patterns, connection counts, HTTP status distributions, and backend errors. After integrating your Alibaba Cloud account with Site24x7, all associated ALB instances are auto-discovered and continuously monitored.
Use cases
- Identify traffic spikes: Track QPS, throughput, and new connections to detect and handle traffic surges.
- Diagnose failures: Monitor upstream connection errors to spot unhealthy backend services.
- Understand user behavior: Analyze 2xx, 4xx, and 5xx response patterns across listeners and VIPs.
- Manage connections: Ensure you are not hitting connection limits by monitoring active, new, and inactive connections.
- Enforce SLAs: Use thresholds on response codes and errors to maintain uptime and reliability guarantees.
Setup and configuration
- Log in to your Site24x7 account and navigate to Cloud > Alibaba Cloud > Add Monitor.
- In the Edit Alibaba Cloud Monitor page, select Application Load Balancer from the Service Types list.
- Once added, go to Cloud > Alibaba > Application Load Balancer to view dashboards and performance metrics.

Threshold configuration
- Go to Admin > Configuration Profiles > Threshold and Availability.
- Create or edit a threshold profile for Application Load Balancer.
- Assign the profile to the respective monitors to trigger alerts.
IT automation
Site24x7's IT Automation tools help with automatically resolving performance degradation issues. When a breach occurs, the alarm engine continuously examines the system events for which thresholds have been defined and performs the mapped automation.
- Go to Admin > IT Automation Templates.
- Create a new automation rule.
- Map the rule to the monitor for proactive resolution.

Configuration rules
With Site24x7's Configuration Rules, you can set parameters like Threshold Profile, Notification Profile, Tags, and Monitor Group for multiple monitors and automate the configuration settings of your monitoring resources. Automatically assign these settings when new Application Load Balancer monitors are added.
