[Nagios-users] autogenerate nrpe.cfg file
What is the best way to autogenerate nrpe.cfg files across lots of servers? Googling, I've found things like Puppet, but that requires a bit more overhead and planning than I have right now. - This SF.net email is sponsored by: Microsoft Defy all challenges.

As Sean made me realize you were actually trying to run the xinetd
config file... In fact all you have to do it probably reload or restart
xinetc. (make sure to kill all instances of the NRPE daemon)

Re: [Nagios-users] Service checks scheduled far in future
The output of the command is below.
I included the objects.cache file. As I understand it, this is created
at run time from what nagios reads from the config files and saves.
Therefore, if I left something out, it should be more obvious here.
If you need the actual files, I can tar and zip 'em, though. I make
heavy use of config_dir and have one file per configuration item.

Your OS LC_NUMERIC settings specify a number format that uses ',' in place of '.' and the script (or perl?) isn't internationalized to understand that. Would that be the case? I'm not too familiar with i18n so can't be of much help. -- Marc - This SF.net email is sponsored by: Microsoft Defy all challenges.

You've modified this timeperiod to _not_ be 24x7 but are treating it
as if it still is. Nagios is doing what you've told it to do.

[Nagios-users] conditional inclusion of cfg files
Okay, let's say you have lots of distributed pollers, which should only load cfg files for their particular environment (both hosts and services). However, you'd like to manage the same set of "global" cfg files from the central server, and rsync them all everywhere. Is there any known way to make a poller just load a subset of cfg files, *without hardcoding it into each poller's nagios.cfg file*? Sorry if this sounds a little crazy. I guess what I had envisioned was a way to push out a set of cfg files named by each poller's hostname, with the expectation that a poller could intelligently include only its own cfg file. Each of those files, in turn, would include a set of cfg_dir definitions to further include the directories needed for the poller to poll its specific environment. Nagios just appears to be very limited in the ability to declare variables in the configuration files. Yes, you can set macros, but that doesn't seem to help me with this particular situation. Any suggestions? - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Nagios-users] NRPE on monitoring host
Some of my nrpe checks works ok now. I'm still having some issues getting
check_disk to return information. Nagios displays: NRPE: Command 'check_disk'
not defined.
In my nrpe.cfg I have the following entry:
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p
/dev/sda1 --> I can run ./configure check_disk... successfully on the remote
system?
In my localhost.cfg I have:
define host{
use check-status
host_name donald
alias Donald
address 192.168.1.21
}
# 'linux-boxes' host group definition
define hostgroup{
hostgroup_name linux-servers
alias Linux Servers
# contact_groups infrastructure-production
members donald
}
define service{
use local-service
host_name donald
service_description cpuload
contact_groups infrastructure-production
check_command check_nrpe!check_load
}
define service{
use local-service
host_name donald
service_description disk - /
contact_groups infrastructure-production
check_command check_nrpe!check_disk
}
The nrpe cpuload check returns results.
In my commands.cfg:
# NRPE
define command{
command_namecheck_nrpe
command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
I can telnet the remote host as well.
