Spotfire Node Manager: Health Detail

Problem:

Spotfire can often indicate a node is strained or exhausted, but also indicate that CPU and Memory are OK.  To know why, you will need to look in the log files.

Details:

You can access the Node Manager logs, via 3 different methods.

1. Remote into the Node Manager's desktop (Windows) or use SSH (linux), and open the \tibco\nm\nm<version>\logs folder.
2. Download the logs via a the Spotfire Admin Monitoring & Diagnostics page.  Click the 3 dot menu at the end of the Node Manager line, and select Download troubleshooting bundle
3. View the logs via the Spotfire Admin Monitoring & Diagnostics page.  Click the View Logs link.

Look for the Spotfire.Dxp.Worker.Host.<GUID>.log file.  Open this and find any lines that contain "instance health status". These lines will indicate all CPU, Memory, Paging, TempDisk, WCF, ThreadPool and Combined status.

Paging: How much data is being pushed to and from disk, because of a lack of memory.

WCF: Microsoft Windows Communication Foundation.  These are communication channels between software components.  This is an indication that the system is not too busy.

ThreadPool:  Is another indication of how busy the system is.
