Like any other test...
I do a simple http test to msn.com like you'd test any website with the
standard plugin.
I do a ping test to yahoo.com since they allow pings still (unlike many
companies).
And I do a dig to google.com.
Those three are each defined as a host, then put in a hostgroup called
"sanity check". If one test fails, I assume there's an issue on there
end and ignore it. If two fail, same thing. If all three fail, I know my
ISP connection is down. The contactgroup for the hostgroup for these
hosts goes to SMS (mine and the mgr at our ISP).

Hi Andrew,
How are you configuring your sanity checks in Nagios?
Thanks.

A combination of the "parents", hostgroups, and escalation. I'll post
my configs later, but once you have confirmed that SMS is setup and
working (make sure that for every email alert, you also get an SMS
alert), then you define your network topology and put them into
hostgroups. In my case, I have a hostgroup of "network-core" which
includes my core routers, firewalls, Exchange server, Exchange
storage, and the switch connecting the Exchange system with the
firewall. I then have a contactgroup of the SMS addresses of three key
people (myself included). If any of those device fail, Nagios sends
notification via SMS. If anything else fails, it goes via emails. The
kewl thing is I'll often sleep through emails, but if I get an SMS, I
know something serious failed and I force myself to get up...
Additionally, I tend to define a sanity check: a ping to yahoo and
http to MSN and non-caching dns query of Google. If all sanity checks
fail and are not resolved within 4 hours, then through escalations, an
SMS is sent to the manager of the support team at our ISP as we likely
have a bandwidth down issue. If sanity checks AND a core network
device fail, my ISP doesn't get notified as we know its us...

I've been messing around with this, off and on (as time permits). How
did you set up your config to go to SMS only if email fails?
Thanks

In "Nagios 2nd Edition" from Wolfgang Barth, he covers this in section
12.4.2. He covers "smsclient", "yasp", and "smssend", but he points
out what Jim pointed out... most are email to SMS conversion tools so
if email is done, you're still not notified. "smsclient" and a modem
resolve this. I have it installed and working fine. Our normal
notifications go via email, but if a network device or email server is
down, then notifications go via SMS.

I'm new one in Nagios system.
I work in mobile cellular operator company. And I need to know is there any
chance to get notification alert via sms to my mobile phone when BSC or HLR
equipments go down or stop working?
Is there any configuration on Nagios? And how to connect Nagios server to
sms center.
Currently I use an external email-sms service similar to
http://www.intellisms.co.uk so I can send emails from Nagios in the
usual way and have them converted to SMS. It's extremely easy to set
up, but has the disadvantage that if the email system goes down, we
don't know about it!
Alternatively, you could connect a mobile 'phone to your Nagios server
and send SMS using gnokii http://www.gnokii.org/ or similar, or your
mobile operator might well have an http interface you could use or can
recommend other options.
In Nagios, you specify the notification methods in command definitions
which you can write yourself so it's extremely flexible. See
http://nagios.sourceforge.net/docs/3_0/notifications.html under the
heading "Notification Methods".
hth,
Jim
