Systems and methods for monitoring operation of a pump, including verifying operation or actions of a pump, are disclosed. A baseline profile for one or more parameters of a pump may be established. An operating profile may then be created by recording one or more values for the same set of parameters during subsequent operation of the pump. A value for a goodness of fit measure comparing the operating profile and baseline profile can be established. If the goodness of fit measure is insufficient, an alarm may be sent or another action taken, for example the pumping system may shut down, etc. An example goodness of fit measure is an R-squared measure.
