Hi i am having a log list like this

\<#\> 20200924 15:14:44.552 000000997 FD.WRN [MVINB-LSL2.T1G1\_ATMTH\_SL main.main ConfigService.ConfigService] Unable to get CommonParamConfig of [DAC\_TEST\_WHILE\_IDLE, \*]. Memory table not loaded yet

\<#\> 20200924 15:14:44.529 000000997 FD.INF [MVINB-LSL2.T1G1\_ATMTH\_SL main.main ConfigService.ConfigService] Update Switched Flag.

If you are parsing out that field, then you could use a translate filter. If you are just passing the message through then you could use mutate+gsub.

Thank you so much @Badger 🤩 Got the respective output by using mutating and gsub =\> ["event\_type" , "FD.WRN" , "Warning"]  
gsub =\> ["event\_type" , "EV.WRN" , "Warning"]
