If you are using *nix system, you have few choices. You can use logrotate service and send SIGUSR1 signal to mongod/mongos process. Or you can change your config systemLog.logRotate: rename and again send SIGUSR1.
To rotate log you can give command db.adminCommand( { logRotate : 1 } ) too.
How you do it on the windows side, that I don't know.

we are using centos7 and we have 4 shard cluster of each in each replicatset consits of (primary+secondary+arbiter ) and config server(primary+2secondaries) and mongos is in windows instance so i need to execute in all instances or can i run it in mongos– ashkDec 8, 2017 at 11:11

Yes.. All Linux mongod instance logs you can handle with my answer. Those windows mongos must use some other method, but I guess that google can answer to that question. I guess that only working solution is that adminCommand with rename.– JJussiDec 8, 2017 at 13:32

In every mongod instance i should run the db.adminCommand( { logRotate : 1 } ) is it correct also in arblter also– ashkDec 8, 2017 at 17:42

Yes, you can rotate arbiter log file with
db.adminCommand( { logRotate : 1 } )too– JJussiDec 9, 2017 at 8:26 -
