PCF built-in metrics information

  • Container metrics: CPU, memory, disk %
  • HTTP metrics: requests per second, HTTP errors per second, request latency
  • App events: create, update, start, stop, and crash
  • Do you understand how to use the metrics to spot a badly performing application? For example: CPU or memory usage?
  1. Set up a custom chart to monitor the application performance (or)
  2. Highlight the CPU Utilization spike keyword in the logs and debug the application to resolve what is causing the spike.
