We are announcing the public preview of Azure Load Balancer health event logs. With health event logs, you can collect, store, and analyze information to help understand the health of your Azure Load Balancer resource. These built-in logs help you troubleshoot specific scenarios and allow you to identify and alert on availability issues affecting your load balancer. Examples of scenarios where Load Balancer health event logs can help are:
- Traffic distribution issues: When your load balancer may not be distributing traffic as intended, due to causes ranging from misconfiguration to Azure platform issues.
- Port exhaustion: When your load balancer may be experiencing outbound connectivity issues due to SNAT port exhaustion.
- No healthy backends: When your load balancer’s frontend has no healthy backend instances to distribute traffic to.
With Azure Load Balancer health event logs, you can monitor the health of your load balancer, without having to set up and manage complex metric-based alerts or build a custom data ingestion pipeline.
Azure Load Balancer health event logs are currently rolling out to all public regions. Learn more about these logs and the current regional availability on our public documentation, or read our latest blog about this announcement.
