# Scheduling Policy Switch Trace Every time _Elektron_ switches to a different scheduling policy, the name of the scheduling policy and the time at which the switch took place is logged. The logs are written to a file named _\<logFilePrefix\>\_\<timestamp\>\_schedPolSwitch.log_, where * _logFilePrefix_ is the prefix provided using the `-logPrefix` option. * _timestamp_ corresponds to the time when _Elektron_ was run. The format of the data logged is as shown below. ``` <yyyy/mm/dd> <hh:mm:ss> <sched policy name> ``` _Note: The names of the scheduling policies can be found [here](https://gitlab.com/spdf/elektron/blob/master/schedulers/store.go#L14)_
