Good Morning,
When we are revewing the information that we send with the offload (With a Central Database) we had a question, if the value of a parameter is constant/lineal for a period of time (for example 15 mins the same value), Dataminer will offload the value or just skip that period of time?
For example, this is the behavior of a CPU of one device:
10:00 am: 10 %
10:05 am: 10 %
10:10 am: 10 %
10:15 am: 13 %
Dataminer will be offload the value from 10:05 am and 10:10 am? Or only offload the value if change ?
We are reviewing the data that Dataminer made the offload to a central Database and we see that behavior, and we want to know it is normal?
We are making the tests on the Dataminer version 10.1.0.0-11319-CU11.
Regards
Hi,
It depends on the settings if you see a value every 5 minutes.
For more info see the help.
In chapter "Configuring the offload rate", it's mentioned that the default interval is 5 minutes and when data offload is enabled then there is the choice of offload type between "All parameter values" or "All changed parameter values". The note in the help states:
"When All parameter values is selected, data will still be offloaded even when the parameter value has not changed. However, real-time data is written to the database with the timestamp of the last change, so that there can be multiple consecutive entries with exactly the same timestamp in that case"
If the real-time data offload is enabled with the default interval and the offload type is set to "All parameter values" then this is normal behavior to see a value in the offload every 5 minutes.
