MySQL trend table cleaning operation

When does DM initiate the MySQL Database cleaning operations? It appears to run every hour, but I can't figure out when it starts. I does not appear to start on the hour and it also does not appear to start at the same time for both the PRI DMA and BU DMA in a failover configuration.

Thanks

Hi Jeff,

I suspect that the timer just starts to run when the software starts, and then runs once every hour starting from that startup time.

Thanks Wouter, that was my assumption also but just wanted to see if anyone knew for sure.
