Do they log that? Most smaller transformers in plants just have over pressure and maybe low level switches.
They can log what ever they want to set up to be monitored.
In the buildings I work among other things we monitor for building temp hi and low, fire, smoke, commercial AC, voltage at the regulators and inverters, state of battery discharge, door open sensors, status of cable air pressure systems...
All that and more in addition to equipment alarms and QOS on the data network.
