TI - Implementing an Event Tracing Solution with Consistently Formatted Logs for the SKA Telescope Control System J2 - Proc. of ICALEPCS2021, Shanghai, China, 14-22 October 2021 CY - Shanghai, China T2 - International Conference on Accelerator and Large Experimental Physics Control Systems T3 - 18 LA - english AB - The SKA telescope control system comprises several devices working on different hierarchies on different sites to provide a running observatory. The importance of logs, whether in its simplest form or correlated, in this system as well as any other distributed system is critical to fault finding and bug tracing. The SKA logging system will collect logs produced by numerous networked kubernetes deployments of devices and processes running a combination off-the-shelf, derived and bespoke software. The many moving parts of this complex system are delivered and maintained by different agile teams on multiple SKA Agile Release Trains. To facilitate an orderly and correlated generation of events in the running telescope, we implement a logging architecture which enforces consistently formatted logs with event tracing capability. We discuss the details of the architecture design and implementation, ending off with the limitations of the tracing solution in the context of a multiprocessing environment.
