I am little bit new with Nagios and try to set it up, when i change a configuration i need to reload or restart nagios.
When i do a reload or restart or even stop, i get a failed notification in red.
i googled about this problem but the solutions , changing in your nagios.cfg the lock file does not help.
Its probaly something doeing with permissions, but i have not the knowledge to set the permission the right way and also being secure ( so no 777)
