No, I understand that.
And is there anyway that I can trigger the check_uptime (plugin
written by me)
all the time when the router is up???
Yes. Define it as a service for your host that runs, say, every 5
minutes 24x7.
. If so please do tell me. If the router is down and
nagios doesnt run then its ok for me. Since that is a different issue.
But from your reply
I came to understand that check_uptime will be called for the first
time when the nagios
is started and then if any of the services fails then again the
check_uptime is called.
Yes. Nagios only checks a host status when it absolutely needs to, not
any other time. This is usually when a service fails, or a network
blockage is detected. check_ping to 127.0.0.1 on this check would work
fine in your case.

Again, as I and Patrick have said, your host's check_command is
only getting run when a service is deemed to have problems.
You're getting the difference in the uptime output in Nagios and
the console because Nagios hasn't run the uptime command for the
host for over a day.
If you're not retaining status information, then when you restart
Nagios, it re-runs all it's checks, hence why it then gets
updated. After that it is only run when a service fails.
What I still don't understand is how your uptime command ensures
the router is up? If the router is not up, then Nagios won't be
running (as you're running it on the same host) so it seems quite
pointless really. If the Lanlink checks that the LAN interface is
up and connected - that makes sense, but then a check_ping to
127.0.0.1 <http://127.0.0.1> as your host check_command would give
the same result as the uptime, then you could have an "Uptime"
service with your check_uptime command.
That way you could be confident that the status detail in Nagios
is reasonably up-to-date.
