Polling ODA Log Status Data

The initial version of the SLT (Shift Log Tool) provided support for fetching observation execution related logs from the ODA e.g. success or failure of EB (Execution Block).

A function named updated_shift_log_info was created to facilitate this process.

The updated_shift_log_info function takes a current_shift_id as an argument, which is the unique identifier of the shift for which log data needs to be fetched.

This function continuously synchronizes log data from the ODA system for the specified shift. It creates a background thread that periodically polls the ODA system for new log data.

Implementation Details

The current implementation of the updated_shift_log_info function follows a background thread-based approach to poll data from the ODA system. The fetched log data is then processed and stored in the ODA.

$ updated_shift_log_info(current_shift_id)
