Orion.Engines.Pollers - What does this represent?

Simple way to spot check would be to do something like

Select count(*) as undp from orion.npm.custompollerassignment

That query could be more elaborate but I'm using my phone and can't really test anything more fancy at the moment.

That query yields the number '240' which seems much more reasonable.

This leaves me still wondering what exactly this number represents and why the primary poller has such a huge number while the additional poller shows 0. Either its not UNDP or my database is severely out of whack.

Yeah I would go with the first option, its probably counting something else.  What exactly it is counting is the mystery.  My lab also has 0 for that number.  It's possible that it could also be counting something that was deprecated before your APE got installed? 

I'm still trying to figure out what that number means, mostly because I'm kinda stubborn.

In the meantime, I've revised the display to count actual UnDP assignments against nodes (I don't have any running against interfaces). The numbers make sense now.

Here's the updated SWQL query in case anybody's curious.

SELECT

    , [N].DetailsUrl AS [_LinkFor_ServerName]

    , toString(Round([N].SystemUpTime/60/60/24,0))+' days' AS [Uptime]
    , CASE
        WHEN (MinuteDiff([OE].KeepAlive,GetUTCDate())<1) THEN 'Just Now'
        ELSE (toString(MinuteDiff([OE].KeepAlive, GetUTCDate()))+' min')
    END AS [LastCheck]

    INNER JOIN Orion.PollingUsage AS [PU]
        ON ([OE].EngineID=[PU].EngineID AND [PU].ScaleFactor='Orion.Standard.Polling')
-- Use of LEFT JOIN so that we can show Engines even if we aren't monitoring them... but we should be monitoring them
    LEFT JOIN Orion.Nodes AS [N] ON [OE].IP=[N].IP_Address
    LEFT JOIN (
        SELECT [N0].EngineID, Count([N0].NodeID) AS [UnDP]
        FROM Orion.NPM.CustomPollerAssignment CP
            LEFT JOIN Orion.Nodes N0 ON CP.NodeID=N0.NodeID
        WHERE [N0].UnManaged=FALSE
        GROUP BY [N0].EngineID
    ) UnDP ON [UnDP].EngineID=[OE].EngineID


ORDER BY [OE].ServerType DESC, [N].Caption

SolarWinds has confirmed that this field is obsolete and no longer updated. The value is currently meaningless.

Thanks everybody.
