    There shouldn't be any need for any merging step. Import your data using PI Builder. In a new column in the imported table, use the PI DataLink function PICurrVal to retrieve the snapshot value.

    Try something like this:
    TagTot('attribute',Bom('*'),'*')
    where 'attribute' is the attribute that is being totalized.

    Bom is a function that returns the beginning of the month. TagTot is a totalizer function (more precisely, it calculates the definite integral of an attribute between a start time and an end time). TagTot assumes that the given attribute is some sort of rate per day, (e.g. liters per day, tonnes per day), so you may need to multiply the result by a conversion factor.

    If your attribute does not represent rates and instead represents the individual values to be summed, you will need to do this:
    TagMean('attribute',Bom('*'),'*') * EventCount('attribute',Bom('*'),'*')
    See this thread: https://pisquare.osisoft.com/thread/7591
    Explanation: TagMean sums the values of all events in a given time range and then divides by the number of events. Multiplying by EventCount of the same attribute over the same time range undoes the division, leaving us with only the summation.

    These approaches are much more concise than, say, this (pseudocode):
    current totalizer value = 0 if the month changed, otherwise previous totalizer value + change since the previous totalizer value

    OSIsoft is committed to providing customers with a more manageable system. We are working hard to solve the problems of deployment, security, and standardized health messaging within our products.

    PI System Health and PI System Directory were early steps in the manageability story, and we learned a lot thanks to significant customer testing and feedback. We also discovered that there is much more to making a truly manageable system through these engagements.  In order to pursue these larger needs surrounding manageability, we will not be releasing PI System Health, and we are putting PI System Directory on maintenance so that our engineering resources can be allocated toward these bigger efforts. As such, there are no additional enhancements for PI System Directory planned at this time.

    As a result, the status of this suggestion will be changed back to “No status” for the time being. Future status updates will be communicated here.

    Watch out for time-weighted totals, since the dimension of the output is not the same as the dimension of the input.
