Load Testing RSTAT Monitoring

RSTAT Monitoring using daemon counters

• NeoLoad provides load testing RSTAT monitoring by accessing daemon counters in real time.
• NeoLoad allow users to monitor the rpc.rstatd daemon that is already installed and running on most Solaris and Linux machines.

RSTAT Monitoring Counters

RSTAT System Counters

• CPU Usage : The percentage of CPU time, for all processors globally, taken up executing user commands, and carrying out system tasks and I/O operations. This monitor takes into account the total number of processors in its calculation of CPU usage.
• User CPU : The percentage of CPU time, for all processors globally, taken up executing user commands. This monitor shows the CPU usage per user across all the processors globally.
• Nice CPU : The percentage of CPU time, for all processors globally, taken up by low-priority processes. The time taken up by "nice" tasks is already taken into account in the System CPU and User CPU times.
• System CPU : The percentage of CPU time, for all processors globally, taken up executing system tasks, including system calls to kernel routines.
• Interruptions count : The number of interruptions occurring during a monitoring interval.
• Context switch count : The number of processor context changes per second.

RSTAT Memory Counters

• Memory Page paged IN : The number of pages moved from the disk into cache memory.
• Memory Page paged OUT : The number of pages moved from cache memory to the disk.
• Memory Page swapped IN : The number of pages moved from swap space to storage space.
• Memory Page swapped OUT : The number of pages moved from storage space to swap space.

RSTAT Network Counters

• Network IN packets count : The number of network packets entering per second.
• Network OUT packets count : The number of network packets exiting per second.
• Network IN errors count : The total number of network errors inbound per second.
• Network OUT errors count : The total number of network errors outbound per second.
• Network Collisions count : The number of network collisions occurring during the monitoring interval. A collision is an undesirable event resulting from competing network packets being transmitted over a same channel.
