API and System Performance Issues Troubleshooting Guide
This guide is designed to help IT operations teams, infrastructure engineers, and DevOps professionals troubleshoot issues related to API calls not responding and overall system sluggishness. Following these steps can help stabilize your environment and improve performance across your hybrid and multi-cloud infrastructures.
Issue Description
If you experience API calls that do not respond or notice your system becoming sluggish, it may indicate service imbalance, excessive open connections, or configuration problems affecting the Control Center UI and core services.
Signs
- API calls timing out or failing to respond.
- Overall system sluggishness or degraded responsiveness.
- Control Center UI becoming inaccessible or unresponsive.
Basic Troubleshooting Steps
- Check for Service Imbalance: Verify that the API service load is evenly distributed across all hosts. An overloaded host can cause API requests to stop responding.
- Monitor Open Connections: Excessive open connections can overload the API service. Consider adding additional zenapi instances to distribute load and restart the API service to stabilize performance.
- Verify Configuration Issues: Configuration errors can cause Control Center UI inaccessibility and impact performance. Restart associated services such as Solr and RabbitMQ to resolve transient issues.
- Notify Stakeholders: Communicate any actions impacting system instances early to your team to minimize disruptions and coordinate troubleshooting efforts.
Advanced Troubleshooting Steps
If the above steps do not resolve the issue, please gather logs, system metrics, and service status reports, then raise a support ticket with Virtana Service Observability for further investigation by our specialists.
