The "AM 6.0.0 CTS" Prometheus/Grafana sample dashboard includes a panel (bottom-left) which should show the rate at which connections are obtained from the DS SDK in order to perform the requested CTS task.
Unfortunately, rather than showing a per-second rate this panel is showing the absolute count of attempts to obtain a connection (broken down into success and failure outcomes).
To fix this issue, the PromQL rate() function should be used:
NB. related to this, the "All Task Throughput" rate() is calculated over a 5 minute window, rather than a 90 second window. It may be desirable to use a consistent window for these calculations (provided this does not lead to gaps in the lines drawn by Grafana).
