Please fine answer for each of the queries:
1. Error message:
--> Error: Service '1001101004' on host '1001101004' is not a valid parent for service '1001101004' on host 'Firmware Version'
Looking at error , I see 1001101004 is being considered as service not host. Not sure if any specific syntax to define host as parent in service.
2. Command used to restart nagios service:
--> service nagios restart
3. Check Interval :
--> All numbers are in seconds since I changed nagios.cfg to use seconds instead minutes
4. I am using default templates of switch and service
