FAQ
Hosts or services simply not showing up
Check if you have more than one instances of nagios running
Debian complaining about rights on nagios.cmd
dpkg-statoverride --update --add nagios www-data 2710 /var/lib/nagios2/rw dpkg-statoverride --update --add nagios nagios 751 /var/lib/nagios2
NRPE: Unable to read output
- This could mean the plugins are not installed ( yes, on debian nrpe comes without those :)
CHECK_NRPE: Error receiving data from daemon.
Possibly SSL version mismatch, try check_nrpe -n
(No output returned from plugin)
Most likely ssl mismatch again. It can also mean you're using debian, where check_nrpe!check_something fails, since it expects one more argument. call 'check_nrpe_1arg' instead.
Error: Could not stat() command file '/var/lib/nagios3/rw/nagios.cmd'!
That's apache missing read rights to the path.
Could not read request from client, bailing out
Another rather useless message, it might mean one end is using ssl and other end not. Check on your system that the nrpe2 agent is compiled with ssl support.
Example:
[my_monitored_host] # ldd /usr/local/sbin/nrpe2
/usr/local/sbin/nrpe2:
libssl.so.5 => /usr/lib/libssl.so.5 (0x80063a000)
libcrypto.so.5 => /lib/libcrypto.so.5 (0x800784000)
libwrap.so.5 => /usr/lib/libwrap.so.5 (0x800a16000)
libc.so.7 => /lib/libc.so.7 (0x800b1f000)
It is OK, while:
[my_monitored_host] # ldd /usr/local/sbin/nrpe2
/usr/local/sbin/nrpe2:
libcrypto.so.5 => /lib/libcrypto.so.5 (0x800784000)
libc.so.7 => /lib/libc.so.7 (0x800b1f000)
is NOT ok.
