Hello,
If it's just two sites... I like to have two Nagios servers. I would put one
in each site. That way if the VPN link is down, you don't lose performance
data from the other site during the window. Plus each Nagios server can
monitor the other. Also I've used my HQ install to monitor
To be rather general...
If you can monitor a device via SNMP, you can monitor it via Nagios. Also you
can use something like NSCA to accept checks/heartbeats from remote
systems/services.
NSCA is a Linux/Unix daemon allows you to
integrate passive alerts and checks from remote machines and
With NSClient++, you can easily copy the INI file around. for NRPE and
NSClient++ config files I always put in 3 generic names as allowed hosts ...
nagios1.domain.local, nagios2.domain.local, nagios3.domain.local. Those 3 are
CNAMEs to my actual nagios systems so I don't have to worry about
I recently ran into a similar testing Nagios/NagVis/PnP4Nagios.
To throw it out there... you are using an older version of PNP as they're
beyond 0.6 now.
I was trying to add a new service and testing. I had been tweaking the check's
command line options to find the write output I wanted.
May or may not be related... When testing new plugins and scripts, make sure
you're testing them as the nagios user the scripts will be running as when
integrated w/ Nagios.
I documented what I did for a previous employer awhile back here:
Perhaps you made a change to the nrpe.cfg and had not restarted NRPE service
previously? I periodically forget to do this myself when updating commands.

We make extensive use of hostgroups for templating.
We define a OS hostgroup. A simple example would be Windows or Linux
host groups where we monitor CPU/Load, Root/C disk space, and memory. The
Windows group has EventLog RDP checks, while Linux groups will monitor the
SSH port.
No firewall rules in play? eg. allowing connections from your Nagios server to
tcp-5666 and allowing the remove server to connect back to your nagios server?
Did you edit the nrpe.cfg file correctly and add the server to allowed_hosts?
Did you remember to restart NRPE after editing the
sounds like you didn't compile NRPE w/ SSL support maybe?

Along the lines
make sure you have hostgroup definitions setup ...
define hostgroup{
hostgroup_name DUMMY2
alias Dummy2 Servers
}
Also NOTE in my test host, I have the line:
use dummy-hosts1,dummy-hosts2
Each defines group DUMMY1 and DUMMY2 respectively...

in the NRPE.CFG file, make sure you have the allowed_hosts= line set
correctly. also if there is a firewall involved, make sure you open the port
to allow the connection.

There is a check called check_file_age which checks file size and age. It
can then easily be tweaked (just do the reverse logic) to check a file to see
if it was changed/modified.
So you can check to see if the file is changing (eg, a log file), or check to
see if someone modifies a file
with support for tdsver=8.0
Thank you for comments

jumping in a bit late on this one...
so it sounds like the check itself works on the local box... so if you run from
the nagios server
./libexec/check_nrpe -H server -P 5666 -t 10 -c check_root
and then...
./libexec/check_nrpe -H server -P 5666 -t 10 -c check_ora

Well, unless you have the historical data to jam into the graphing application,
it will only be data going forward.
I found nagiosgraph simple and easy enough for my nagios setups. It requires
RRDtool. If graphing is a critical aspect, I would look for a more robust
graphing package
my server config file defintion is:
check_command check_nt!MEMUSE!-w 75 -c 90
I believe this is pretty much out of the box setup... of course you'll want
to check the check_nt command definition in the commands.cfg file.

What is your service configuration? If you're checking SMTP remotely, there is
no need for NRPE here. I would guess your service configuration is not passing
the correct variables.

installing from source should be pretty easy on a Fedora system. any missing
dependencies can be installed with yum. the documentation is pretty good on
this topic as well letting you know what you may need.
make sure you have openssl-devel installed, that always trips most installs up.
do you host your website internally? if not, ping that host and or do an HTTP
check of it.
one thing i highly recommend is using a small little VPS ($10/mo even) to do
some basic monitoring. I use one personally for testing and to monitor my
websites, friends websites, our email and dns
Hrm, I bet you could even do a few things with a batch script. I haven't
flexed those muscles in awhile, but you would be surpised what can be done.
Would you care to share the script? I would love to try it out in my test
environment.

The documentation on this is actually pretty good...

If you have a host that use's the template... then in that host's config you
define the same value again, it will override... except if you use the ! and
+ signs to change
you can probably easilly fix with openssl-devel
if you have yum... yum install openssl-devel is all you have to do.

Alot depends on the type of checks, the check frequency, and timeout values.
For example, we have ALOT of webinject (perl script) tests which can take 20-40
seconds to complete. With a retry_interval of 1min, when we have some
issues, we can quickly have many checks running simultaneously
just a thought...
is $HOSTNAME$ valid? sure you don't mean $HOSTADDRESS$ instead?
