N3T_CPU_Pct_Critical

CPU percent critical is the percentage of CPU being used by TCP. High CPU usage is frequently accompanied by a high throughput rate. To determine the source of this problem, use the following steps:

  1. Determine if the throughput rate is excessive.
  2. Examine the application throughput rates to isolate the source of the high throughput.
  3. Look for a high byte rate on a connection to isolate the sorce to individual connections.

Possible solutions include:

  • Load balancing applications across multiple OS images
  • Terminating connections
  • Scheduling work for non-peak hours
  • Adding capacity

Formula: CPU Percentage >= 10
