Thanks excowboy, i did the same and could see Nagios listed under "Deployed Servers Health" , but which i click on this service, i do not see any thing.
I have attached the snapshot of the same, kindly review.
One more observation is that, if i do the same thing to sendmail service, i get the required detials. Snapshot of the same is also attached in the same attachment.
Kindly help.
