I have an EMDVB interface as well as all the healthpoint which are created automatically by PI System.
I am having the following issue, all healthpoint are updated "Rapidly" except from the deviceStatus tag. When i checked the Snapshot of the HealthPoints, the only one which has a timestaped not recently updated is the DeviceStatus tag. Sometimes, it may be 10 hours in the past.
I would like to know, if someone has come across this issue :
1. why this healthpoint (DeviceStatus) take long before updating its snapShot.
2. What is the rate at which this tags get new snapShot or values in archive.
