What is measured

JMeter test results & metrics

• Total Events Sent - total number of events sent by JMeter (including failed requests)
• Failed Requests - total number of failed requests 
• Error Rate % - 'Failed Requests' to 'Total Events Sent' ratio in percentages
• DMaaP - Received Events -  total number of events received by DMaaP on Fault topic
• Total Throughput - number of events sent per second by JMeter
• Total Errors - failed requests per second
• Active Threads - number of active threads per second
• Sync Processing Time (Client → VES) - time measured from sending the request by JMeter to receiving the response by JMeter 
• Async Processing Time (Client → VES → DMaaP) -  time measured from sending the request by JMeter to receiving the event by DMaaP
• RAM Usage - RAM usage of JMeter VM
• CPU Usage - CPU usage of JMeter VM

Ves metrics

• Uptime - how long VES is running
• Start time - when VES has been started
• Heap used - current Heap usage in percentages
• Non-Heap used - current Non-Heap usage in percentages
• Processing time eventListener endpoint - method execution time in VES
• Rate - number of HTTP requests per second
• Duration - maximum and average HTTP request processing time (HTTP request other than 5xx) in milliseconds
• Errors - number of 4xx and 5xx requests per second
• JVM Heap - JVM Heap usage 
  • used - the amount of used memory
  • committed - the amount of memory in bytes that is committed for the Java virtual machine to use
  • max - the maximum amount of memory in bytes that can be used for memory management
• JVM Non-Heap - JVM Non-Heap usage
  • used, committed, max as in JVM Heap 
• JVM Total - JVM Heap + JVM Non-Heap 
  • used, committed, max as in JVM Heap
• CPU Usage - VES CPU usage (Note, that VES can use the whole CPU available on the Worker Node)
  • system - CPU usage for the whole system
  • process - CPU usage for the Java Virtual Machine process
  • process-1h - average CPU usage for the Java Virtual Machine process over 1h
• Load
  • system-1m - number of runnable entities queued to available processors and the number of runnable entities running on the available processors averaged over a period of time
  • cpus - the number of processors available to the Java virtual machine
• Threads 
  • live -  the current number of live threads including both daemon and non-daemon threads
  • daemon - the current number of live daemon threads
  • peak - the peak live thread count since the Java virtual machine started or peak was reset
• Thread States - The current number of threads depending on the state
  
  • runnable
  • blocked
  • waiting
  • timed-waiting
  • new
  • terminated

K8s metrics

• Nodes CPU Usage - current CPU usage on each worker node 
• Nodes RAM Usage - current RAM usage on each worker node
• Nodes Total CPU usage - CPU usage on each node over time
• Network Usage Receive - incoming network traffic on each node in MBs
• Nodes Total RAM Usage - RAM usage on each node over time
• Usage of each core - CPU usage of each core on each worker node
• Network Usage Transmit - outgoing network traffic on each node in MBs
