After running the Cisco UCS servers for a period of time, their System Event Log can begin fill up and present as a very generic error within ESXi. This occurred on four ESXi servers that were upgraded approximately the same time. While the logging will continue, it is quite a nuisance to view within vCenter. Even more so with the lack of flash to HTML5 support on the older UCS CIMC modules, like the ones running this blog. Thanks to CLI access, it can still be remediated.
