Just use: `%{HTTPD_ERRORLOG}`

@Rios Thanks. My requirement is I want to separate the log file field like below, so that they can use the field name and search the logs..  
date\_server1 = Fri Jun 09 08:26:38.311375 2023  
domain\_server1 = [https://example.com/](https://example.com/)

Can you advise for this configuration..

Thanks.
