First of all you need to get MongoDB connection from the MongoDB Source Config, it can be done as follows:
import com.mongodb.DB;
import org.apache.jmeter.protocol.mongodb.config.MongoDBHolder;
DB db = MongoDBHolder.getDBFromSource("mongodb source name", "database name");
Next you just need to call DBCollection.insert() function like:
db.getCollection('your collection name').insert(your DBObject payload here)
