Display Transactions Per Second
Follow this procedure to set how many transactions per second (TPS) the MATRIXX Engine servers or pods process. A TPS measure is useful to get a general idea of the health of the engine. Some print_engine_stats.py script TPS statistics are calculated for all engine servers or pods twice, the results are averaged, and the total for all servers or pods is returned. Other statistics only apply to the processing servers or pods, and those result tables are marked with an appropriate footnote.
About this task
Note: It is a good practice to
run the print_engine_stats.py script with the -e
engine parameter to ensure that the data returned is for the correct
engine.
Procedure
Run the following command to display the TPS for each server in an engine:
kubectl exec -it engine_pod_name -n matrixx -- bash --login -c"print_engine_stats.py"Results
