Converting value in field

[Lokesh_Mayan]

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.

I want to convert the all the value with "FD.WRN" with "Warning" and "FD.INF" as "Info" and display as "warning" "Info" in the kibana. is there any way?

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"]
