Troubleshooting Guide for Endpoint Client (EPC)
Agent Connection Errors
Symptom: Agent fails to connect to the Controller.
Causes:
1. Domain or passphrase mismatch between Agent and Controller.
2. Network routing issues.
3. Firewall or NAT blocking communication.
4. Make sure EPC installed properly.
Solutions:
1. Verify domain and passphrase configurations.
2. Check network connectivity between Agent and Controller.
3. Ensure firewall rules allow required ports.
4. Re-Install Software, ensure the “Nectar End-Point” service is running.
Symptom: Agent appears Unlicensed in controller
Causes:
1. There is no license associated to the Resource Group
2. The OrgID/GrpID are incorrect.
Solutions:
1. Verify there is a license associated to that Resource Group.
2. Verify correct OrgID/GrpID is configured into the EPC .
DXP Database Connection Issues
Symptom: EPC components fail to connect to the DXP database.
Causes:
1. Database server is offline.
2. Incorrect credentials in DXP EPC configuration.
3. Network issues between EPC and database server.
Solutions:
1. Start the database server and verify its status.
2. Update credentials in the DXP EPC configuration file.
3. Test database connectivity using a database client tool.
Testing Errors
Test Plan Execution Fails
Symptom: Tests do not start or produce no results.
Causes:
1. Misconfigured Test Points.
2.Test Group is not running.
3. Network issues between Test Points.
Solutions:
1. Double-check Test Point configurations.
2. Ensure that the test group is running
3. Ensure network connectivity between source and destination.
Inconsistent Test Results
Symptom: Results vary widely between runs.
Causes:
1. Network congestion or instability.
2. Resource limitations on Agents or Controllers.
Solutions:
1. Analyze network conditions during test periods.
2. Reduce the number of concurrent tests or allocate more resources.
Monitoring Issues
Agent Health Warnings
Symptom: Agents show low resource availability or fail intermittently.
Causes:
1. Insufficient CPU, memory, or bandwidth on the Agent machine.
2. Overloaded Controller managing too many Agents.
Solutions:
1. Increase system resources on Agent machines.
2. Distribute Agent management across multiple Controllers.
Missing Metrics in Results
Symptom: Test results do not display certain expected metrics.
Causes:
1. Metrics not enabled in Test Plan configuration.
2. Misconfiguration payloads or codecs.
Solutions:
1. Review Test Plan configuration for missing options.
2. Update test parameters to include the required metrics.
User Errors
Cannot Access the EPC Controller GUI
Symptom: Users cannot log in to the EPC web interface.
Causes:
1. Incorrect credentials.
2. GUI service not running on the server.
Solutions:
1. Verify login credentials with the administrator.
2. Restart the GUI service or check the server’s status.
Difficulty Creating Test Plans
Symptom: Users encounter errors or confusion during Test Plan creation.
Causes:
1. Incorrect Test Type selected.
2. Missing or invalid parameters.
Solutions:
1. Follow the step-by-step guide in the manual.
2. Validate all input fields before saving the Test Plan.
