Thanks. Looks good.

You should always perform your tests as the nagios user. Root can run
commands that a normal user might not be able to (including ping) and
you may see different output. In any event, the output above for this
host looks good. Do you have the same check-host-alive command specified
for KWA-Core-7206 and MOR-7206? I am presuming that you can't ping this
host because one/both of those are down? How about the same kind of test
run for those two hosts. Also, try pinging them directly from the
command line with /bin/ping -n -U -c 1 172.29.xxx.xxx.

Did you upgrade the plugins when you upgraded nagios? Were there any
other system upgrades performed at the same time?



I ran the exact same test as the nagios user and got the same result:
[root at vuo02web nagios]# su nagios
sh-3.00$ /usr/lib/nagios/plugins/check_ping -H 172.29.248.75 -w
3000.0,80% -c 5000.0,100% -p 1
CRITICAL - Plugin timed out after 10 seconds


As for the KWA-Core-7206 & MOR-7206 sites; these are both UP and
pingable.  I know that the two sites currently showing UNREACHABLE are
down.  We can confirm this by looking at their tunnel status.  However,
in previous versions of Nagios, it would show the site as DOWN rather
than UNREACHABLE.  

As well, the Status Information would display something like "CRITICAL -
Plugin timed out after 10 seconds" rather than "(No output!)".  I am
assuming this is a plugin issue, but, as mentioned before, I am assuming
the plugins are working as the same check-host-alive command works for
sites that are up.

When we did the upgrade, we basically wiped the whole Nagios system and
installed the new version.  The new latest plugins were installed along
with version 2.4 of Nagios.  The old cfg files were copied into the
config directory and modified to fit the new parameters.

Thanks,
Jason
