Hi there --
We are running Nagios 3.1.2 with the NRPE 2.12 client on our systems.
We recently installed the VirtualBox application
on one of our monitored systems, and have Ubuntu 10.04 LTS 64-bit as
the guest operating system. We want to monitor
the disk usage, processes, mysql server, and rsyslogd daemon on the
virtual machine, so the NRPE client was installed
and configured to start on system boot. After that was done, the
appropriate changes were made to the various config files
on the Nagios server. The virtual machine and Nagios server were
rebooted, in that order, after the changes were made.
When going through the web interface on the Nagios server, the virtual
host does not appear listed in any of the pages.
I confirmed the nrpe daemon was operational on the client, and also
verified that port 5666 was open, and the firewall on the
client was deactivated. The nrpe daemon is run via the /etc/rc.local
file using the following command syntax:
/usr/local/nrpe/bin/nrpe -n -c /usr/local/nrpe/etc/nrpe.cfg -d
I checked the Nagios server, and confirmed the virtual host was listed
in the /etc/hosts as well as the nagios configuration
files. The nslookup command, run on server and client, confirmed the
presence of the virtual host in the DNS database.
What would cause the client not to appear in the Nagios web interface,
and how can I correct it?
check if the host has been registered into the core itsself -
objects.cache and/or status.dat
probably a faulty configuration is causing the configuration not being
accepted.
to be sure, please post any accurate configs on that host.
Thanks.
