setting up nrpe on opnsense 24.1.1| config set back after reboot

[RP_pro]

hi
i installed the plugin and configured the nrpe service.
on this i have two major problems.
i edited the file /etc/rc.conf with the following line
--------------
nrpe_enable="YES"
--------------

but when i execute service nrpe start i got the following error
----------------------
Cannot 'start' nrpe. Set nrpe_enable to YES in /etc/rc.conf or use 'onestart' instead of 'start'.
----------------------

the second issue with the configuration itself. i modify the file
/usr/local/etc/nrpe.cfg

but after any reboot this file is set back to empty. (like it was in the beginning) 
i would think that the installation is not permanent but all the changes done to /etc/rc.conf are persisted.
only the config /usr/local/etc/nrpe.cfg is set back
also all other configuration trough the web interface are stored and correctly reloaded after the reboot.

thank you for any advice how to solve these issue

i could find the solution for the first part
to start the service automatically we have to change the file
/etc/rc.conf.d/nrpe
with
nrpe_enable="YES"

not the file /etc/rc.conf

the second problem, (the reset of the configuration file is still an open issue)
even the file /etc/rc.conf.d/nrpe is set back after reboot


but the funny part i modified the file /usr/local/etc/nrpe.cfg.sample
with my right configuration, this file is persistent!

Why are you not navigating to Services > NRPE and using the UI to enable and configure the service as intended?

this was the solution of my mystery
