HAProxy is a critical load balancer for many infrastructures, and any downtime can lead to significant traffic disruptions. This policy ensures the HAProxy service stays operational by restarting stopped instances and immediately notifying your team of issues.
Description
The HAProxy monitoring policy continuously checks the service’s status on Linux devices tagged with “haproxy.” If the service stops or isn’t running, it attempts an automatic restart and generates an alert in real time. This allows teams to resolve issues quickly and ensures uninterrupted traffic distribution across the infrastructure.
Preview
Use Cases
Maintaining uptime for production load balancers powered by HAProxy.
Ensuring high availability for web applications relying on HAProxy for traffic routing.
Reducing downtime for mission-critical applications in distributed environments.
Automating monitoring for HAProxy instances in multi-node setups.
Recommendations
Tagging: Tag all HAProxy servers with “haproxy” for accurate monitoring. We recommend automatically tagging to avoid missing key devices. See “Service Based Tagging” automation as an example.
Testing: Simulate service failures to validate the monitor’s functionality.
HAProxy Config: Regularly check and optimize HAProxy configuration files to avoid unnecessary service disruptions.
Alert Settings: Ensure alert notifications are configured for the policy.
FAQ
Will this monitor check HAProxy configuration validity? No, it monitors service availability. Use HAProxy-specific tools to validate configurations.
Can I change the frequency of checks? Yes, adjust the polling frequency in the policy settings.
What if the service doesn’t restart successfully? Review HAProxy logs for configuration issues or resource constraints.
