I have used ehcache-monitor today. i do anything mentioned in README file and after prepariong anything., i have run "startup" script. now, i can see ehcache-monitor panel via http://localhost:9889/monitor. the prob;lem is : the panel asks me username/password to login to the web panel. is there any default username/password for the web panel? how can i use default user/pass or change the web panel user/pass?
