Hi,

I'm having a problem when trying to run/install the passive NRDS configuration on one of my hosts.

I get the error: ERROR: CONFIG_OS is not a valid cfg field.

It seems that this happens only to configurations that I create or update after the upgrade to 2012 a few weeks ago. My other passive clients don't have "CONFIG_OS" in their configuration files. But I figure as soon as I update them from within XI, they will start having errors too.

Here's the error I get... i tried reinstalling the client completely:

Code: Select all

# sh installnrds fms1.nps.edu 5
nagios group already exists.
nagios user already exists.
Installing NRDS Client

Adding cron jobs for fms1.nps.edu at a 5 minute interval

Crontabs installed OK
Updating config and plugins
ERROR: CONFIG_OS is not a valid cfg field.
Installation complete

Here's the top part of a config that works OK (I removed the token):

Code: Select all

CONFIG_VERSION=1.3
CONFIG_NAME=FMS_WEB
URL=https://nagios.nps.edu/nrdp/
TOKEN=xxxxxxxxxxxxxxxxxxxxxxx
PLUGIN_DIR=/usr/local/nagios/libexec
SEND_NRDP=/usr/local/nrdp/clients/send_nrdp.sh
TMPDIR=/usr/local/nrdp/clients/tmp
COMMAND_PREFIX=
UPDATE_CONFIG=1
UPDATE_PLUGINS=1

Here's one that is reporting the error... it seems the format has been changed in the new XI version.

Code: Select all

CONFIG_VERSION="0.2"
CONFIG_OS="Linux"
CONFIG_NAME="fms1.nps.edu"
URL="https://nagios.nps.edu/nrdp/"
TOKEN="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
HOSTNAME="fms1.nps.edu"
PLUGIN_DIR="/usr/local/nagios/libexec"
SEND_NRDP="/usr/local/nrdp/clients/send_nrdp.sh"
TMPDIR="/usr/local/nrdp/clients/tmp"
COMMAND_PREFIX=""
LOG_FILE=""
UPDATE_CONFIG="1"
UPDATE_PLUGINS="1"

This is my first support request - so I apologize if I'm not including some important info from our instance. Thanks for any help!!

Our XI server is running Redhat 6, and we did the manual installation of XI (i.e. we did not use the vm image).

There was a transition that happened a while back (which included a switch to perl as well as the CONFIG_OS addition) and I think your version of the NRDS Config Manager is somehow different than what is deployed to your machines.

Can you re-deploy the agent to the remote machine?

Hi thanks for the reply. So I did a brand new client install using NRDP. On the client, I nuked the /usr/local/nagios and /usr/local/nrdp folders. On the server, I created a brand new NRDS config package using the default checks, and selected Linux as the O/S.

But I am getting the same error on the client when I download the new client and try to install. It just doesn't like the CONFIG_OS parameter in the config file. Maybe our XI server is delivering an incorrect set of scripts that haven't been updated yet somehow?

Code: Select all

[root@fms1 clients]# sh installnrds fms1.nps.edu 5
nagios group already exists.

I checked the contents of the newly installed script at /usr/local/nrdp/clients/nrds/nrds.sh .... trying to find some version information. Here's what I found from the top of the file.

Did you re-download the client from the XI server?

Lets make sure it didn't rename the tar.gz.1

Code: Select all

ls -l /tmp/|grep tar.gz

Hi - yes I did it twice even to be sure. Each time I cleared out any related files/folders from /tmp, and I redownloaded the install package using a fresh link from the NRDS config manager page.

Can you please run the following on the client and report the results

Code: Select all

ls -l /usr/local/nrdp/clients/nrds/

Thanks

Code: Select all

I think I see the problem, the nrds config manager must not have upgraded on the server

Can you run the following on the XI server

Code: Select all

cd /usr/local/nagiosxi/html/includes/components/nrdsconfigmanager/
rm -f installed.nrds
./installnrds

Then lets re-download the client tarball and install
