I think you need to explain what you're trying to do overall, as this
isn't making any sense to me!
You cannot possibly determine which server is responding using it's
uptime output.
A more sensible option surely would be it's hostname?
#!/bin/bash
hostname
exit 0
However you're going to run into a lot of trouble trying to use Nagios
to monitor a server using its dynamic IP address.
I think to start with you need to be looking at a solution such as
Dynamic DNS (e.g. No-IP, DynDNS for commercial services, or Bind with
DNSSEC/TSIG if you use Bind within your organisation.)
Your machines would then change their DNS address when they detect their
IP address has changed, and you would definite it's dynamic DNS hostname
as the host_name directive to Nagios.
Only thing you'd have to watch would be if your DNS service fails,
Nagios will fail on everything.
Re your last e-mail, please give example outputs of what you see on the
command-line and what Nagios says.

Actually the problem with the ping is that we are giving dynamic IP

so when the ip address changes its difficult to know who is responding
to the
ping. And so we moved to ssh and uptime...

Hi Andy,
Actually my problem is that it works for some 1 day or more. But
after that I get these sort of
results. So thats what makes me worry...

I have exactly the same plugin (written myself with a couple
of differences to yours) which runs as a service called
"Uptime" on every host - this way it is always run every 5
minutes and shows up-to-date info.
The host check is a simple check_ping.

Are you running this command as both a host check and a
service check?
If so, that's why you're seeing different output. The
host check will
only run if a service on it goes to a non-OK state, and
probably hasn't
run for a few days, when the host had only been up for
two minutes.
It looks like you've defined the same plugin for two
checks. If that's
the case, they are never going to match.
