Time series settings

The Time series settings section allows users to customize how time series data is written to storage. These settings can be adjusted to reduce hardware wear by controlling buffer sizes and lifetimes. You can find these settings under Settings in the Time series Settings collapsible section. time series view

Configuring time series settings

To customize time series settings, adjust the following options:

  1. Total buffer size:
    This setting specifies the maximum total size of all buffers, in bytes.

    • Setting it to 0 disables the total buffer size check.
    • The lowest accepted value is 16 kB.
    • The default value is 32 MB.

  2. Buffer size per variable:
    This setting defines the size of the buffer for each individual variable, in bytes.

    • Setting it to 0 disables the entire long-term buffering feature.
    • The lowest accepted value is 128 bytes.
    • The default value is 16,384 bytes (16 kB).
    • Note: Empty buffers do not consume any memory, and there is no pre-allocation of buffer memory.

  3. Buffer lifetime:
    This setting defines the maximum allowed age of the buffer for a single variable, in seconds.

    • Setting it to 0 disables the age check.
    • The lowest accepted value is 10 seconds.
    • The default value is 600 seconds (10 minutes).
    • This setting helps prevent data loss over long periods in the case of power failures or crashes, especially for low-frequency data.

  4. Save changes:
    After adjusting the settings, click the Save changes button to apply your configurations.

These settings allow you to fine-tune how time series data is managed, ensuring that storage is handled efficiently and hardware wear is minimized.
