error while saving aggregate report response in csv

While running the below command I am getting the log4j error. I need to save the aggregate report output in CSV format

PS C:\JMeter\bin> java -jar "C:\JMeter\lib\cmdrunner-2.0.jar" --tool Reporter --generate-csv "D:\Automation\Aggt_rpt.csv" --input-jtl
"D:\Automation\output.jtl" --plugin-type AggregateReport

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.

You can ignore the log4j2 ERROR message as since JMeter 3.2 there was a change in JMeter logging subsystem which was not adopted by all the plugins.

With regards to second WARNING - you can ignore it as well. Alternatively you can re-launch the command as Administrator
