      A protocol, for Dish LMC to ingest logs from SPF or& SPFRx devices is:

      • agreed between OMC architects, Cipa and Karoo,
      • documented in the Solution Intent.

      Test results show that:

      • Dish LMC's logger device received logs from a TANGO device that is deployed inside the k8s cluster,
      • Dish LMC's logger receved logs from a TANGO device that is deployed outside the k8s cluster,
      • the SKA Logging service received those logs from Dish LMC's logger device.

      Test results show that:

      • Dish LMC's logger device received logs from a TANGO device that is deployed inside the k8s cluster,
        • Logs of SPF and SPFRx simulators are triggered by sending a TANGO command to them - see comment on KAR-548
      • Dish LMC's logger received logs from a TANGO device that is deployed outside the k8s cluster,
        • This could not be achieved using a TANGO device that lies outside of k8s cluster because we relied on showing how Dish LMC forwards logs of PSI MID SPFRx to the logging system because integration between SPFRx and Dish LMC could not be achieved in time, and because the MID PSI is not set up to forward logs to STFC Logging System.
        • DishLogger receives logs from a device that has DishLogger as only target target - see comments on KAR-549
      • the SKA Logging service received those logs from Dish LMC's logger device.

      Added commands (SetDishLoggerTarget and RemoveDishLoggerTarget) to DishLogger to add and remove logging target  - https://developer.skao.int/projects/ska-dish-lmc/en/latest/package/DishLogger.html

    Description

      SPF and SPFRx TANGO devices are deployed outside of the k8s cluster. Dish LMC is required to ensure that their logs end up in the SKA Logging System. Dish LMC is also required to locally store the logs of Dish in a 12 hour rolling buffer.

      Agree protocol (for example TANGO Logging Service) for Dish LMC to ingest logs from SPF and SPFRx devices (these are not deployed in k8s cluster).

      Test Dish LMC's logger reception of TLS logs from a TANGO device that is inside k8s and sending of those logs to SKA Logging service.

      Test Dish LMC's logger reception of TLS logs from a TANGO device that is outside k8s and sending of those logs to SKA Logging service.
