Hi Emir, So I made few changes to the log4j config , I am able to redirect these logs to another file as well. But as these are the WARN logs so I doubt any logs enabled at WARN level are going to be redirected here in this new log file. So precisely , I am using Solr 6.1 (in cloud mode) & I have made few more changes to the logging levels and components. Please find my log4j at : *https://pastebin.com/uTLAiBE5 <https://pastebin.com/uTLAiBE5>*
Any help on this will surely be appreciated. Thanks again.
