To troubleshoot and diagnose issues with a PI Collective that cannot accept many connections and requests, you can follow these steps:
1.Check System Resources: Ensure that the PI Collective members have sufficient CPU, memory, and disk resources. High resource utilization can limit the number of connections and requests the system can handle.
2.Review PI Message Logs: Examine the PI Message Logs on all members of the PI Collective for any error messages or warnings that might indicate the cause of the issue. Look for messages related to connection limits, network issues, or resource constraints.
3.Network Configuration: Verify the network configuration between the PI Collective members. Ensure that there are no network bottlenecks or latency issues that could affect communication between the servers.
4.Buffering Configuration: Check the buffering configuration on the interface nodes. Properly configured buffering ensures that data is sent to all members of the PI Collective efficiently. Make sure that n-way buffering is enabled and correctly set up.
5.Connection Limits: Review and adjust the connection limits in the PI Data Archive configuration. The MaxUserConnections and MaxUserSessions parameters can be adjusted to allow more connections if needed.
6.Load Balancing: Implement load balancing to distribute the connection load evenly across the PI Collective members. This can help prevent any single member from becoming a bottleneck.
7.Performance Counters: Monitor PI System performance counters to identify any potential issues. Key counters to watch include Connections, Requests, and Queue Lengths.
8.Update and Patch: Ensure that all PI Collective members are running the latest versions and patches of the PI System software. Updates often include performance improvements and bug fixes.
9.Consult Documentation and Support: Refer to the PI System documentation for detailed troubleshooting steps and best practices. If the issue persists, consider reaching out to OSIsoft technical support for further assistance.
