Configuring Buffer settings

Buffer Mechanism

In buffer mechanism, there are two options:

  • Default Buffer Mechanism: It provides parallel upload from cache and real time data. It prioritizes newest data to old data while storing (works as a last in, first out (LIFO))
  • Chronological Buffer Mechanism: It is chronological upload of data. If "Chronologic Upload" is selected, the buffer mechanism will prioritize oldest data to new data (works as first in, first out (FIFO)).

You can configure the buffer behavior from "Network and Diagnostic Settings" screen.


If the buffer behavior is changed, it will restart the data collection process and this process will take few minutes.

Data loss

The data collection will be stopped during the time of buffer behavior change. The amount of data collection is stopped for few minutes, it depends on restart of the device.

To perform a buffer behavior change proceed as follows:

  1. In "Asset" tab, select the asset.
  2. Open "MindConnect" plugin.
  3. Click Settings, next to "Onboarding Status".
  4. In "Buffer Behavior" section, select "Chronological Upload".
  5. Click “Save”.


Chronologic Upload Specification

  • If there is a bad network connection or no connection at all, the data is going to be stored in cache memory. In "Chronologic Upload", overwritten of cache memory is not possible. Only if there is any space on cache memory, the data is going to be written to it. If the cache memory reaches out it's limit and filled with data, then the data is not going to be saved on cache memory. It will cause data loss until some data is uploaded.
  • As chronological upload the flow of real data to cloud will take longer time comparing to default behavior.
  • The events are not cached in any case of the disconnection. Therefore, "Chronologic Upload" is not applicable for the event upload.
