NRDS Configurations in Linux

[charmainequek]

hi,
i would like to find out if there is any quick way to change the nrds config for some of my hosts which are currently attached to a nrds config?
What i mean is 1 currently have x host that is passively monitored by nrdp using a nrds config x, due to some unique checks that i would like to add to host x but do not want to apply the same check to others hosts using the same nrds config x.
i would like to migrate host x to a new nrds config template but without going through the reinstalling nrdp client step.
May i know if there is any fast / manual way to point the host x to the new nrds config?
i have tried to manually edit the /usr/local/nrdp/clients/nrds/nrds.cfg to change the "CONFIG_NAME" to the new config name i have created in Nagios XI under NRDS Config Manager but it doesn't seem to work.

Please advise if i have missed any steps or how can it be done. Thanks.

You would edit /usr/local/nrdp/clients/nrds/nrds.cfg on the client, changing both the CONFIG_NAME AND set

Code: Select all

CONFIG_VERSION="0.0"

The config will only update if the version is lower than the version returned on the server.

hi scottwilkerson,

thanks for the information. i will try it out.
Can each client only use 1 config template? i have some checks for a particular linux host that i do not want to apply to other linux hosts.
Can i create another linux template and apply it to the client? i.e. apply 2 templates with different checks to 1 client.

Thanks.

This KB article will help understand how the logic works in the backend.

By default when nrds.pl is executed (by cron) it uses the default config file nrds.cfg.

You could add a second cron job that specifies a seperate config file, for example:

Code: Select all

*/2 * * * * /usr/local/nrdp/clients/nrds/nrds.pl -H 'centos13' -c /usr/local/nrdp/clients/nrds/nrds_custom.cfg > /dev/null 2>&1
