Configuring diagnostic settings

Buffer Mechanism

In buffer mechanism, there are two options:

  • Default Buffer Mechanism: It provides parallel upload from cache and real time data. It prioritises 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 prioritise oldest data to new data (works as first in, first out (FIFO)).

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

NOTE

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

  • Buffer mechanism restricted to MindConnect Nano and IoT 2040.

NOTE

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. It may take longer time on slow devices like, IoT2040.

To perform a buffer behavior change proceed as follows:

  1. In "Asset" tab, select the asset.

  2. Open "MindConnect" plugin.

  3. Click 148976438795.png, next to "Onboarding Status".

  4. In "Buffer Behavior" section, select "Chronological Upload".

  5. Click “Save”.

NOTE

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.
