What these pages offer you

You are busy. We get that. We are honored that you cracked open this page. The link you clicked wasn't purple until today.


You may instead be one of those rare people that can say, "I've been a Nagios admin since it was called Saint. You don't need to tell me anything." If you have the honor of being this expert, I still ask you to read the next section.

If you remember nothing else on this opening page...

titleOP5 does not support editing configuration files directlly!

Editing OP5 configuration files directly (in other words: in '/opt/monitor/etc' on the OP5 server) is not supported!

Later in this Guide we will present Livestatus, which parses the configuration files based on a temporary save file. Any manual edits could conflict with Livestatus data as well as anything passed to the API.

We need to make this as clear as possible. Many people reading this Guide may come from Nagios administration, where editing the configuration files and creating new files are commonplace. We beg of you to leave these files alone. Please let our complex of miniature databases serve your higher goals.
