The Node Resources portlet allows you to monitor physical and virtual resources to locate over- or under-utilized resources and isolate performance or system issues. You choose which system and resources to monitor on your Teradata Database system.

The Node Resources portlet provides metrics about the following:
  • Percentage of CPU used by nodes or vprocs
  • How system resource usage is spread across the vprocs
  • How much physical disk I/O, BYNET traffic, or host reads and writes are occurring
  • Whether congestion or excessive swapping is an issue on a single or group of nodes or vprocs

These metrics allow you to analyze data and detect issues, such as poor node or vproc parallel efficiency or higher than expected disk read/write ratio or swap I/O rate.

The Node Resources portlet provides controls that let you choose what information is displayed.
