Silent ping request logging

[Junyang Xin]

Hi,

The ping request log as below generates too much noise in my solr log:
INFO: [main0] webapp=/solr path=/admin/ping params={} status=0 QTime=0

I don't want to change the global logging level to eliminate this. Instead,
I wonder if there is a way to change the logging level just for such ping
requests in the code. If so, which class I should look into? Your help will
be really appreciated.
