Create custom configuration files

Overview

When you create new configuration objects in OP5 Monitor, you can change the default configuration file setting to use a custom configuration file. The procedures below are for advanced OP5 Monitor users with command line experience.

Caution: We recommend always using the default OP5 Monitor configuration files when possible.

Create a custom configuration file

Log on to the OP5 Monitor server as root, using SSH.
Create the following new /opt/monitor/op5/nacoma/custom_config.php.
Add the following code to the file:
```
<?php
$notouch_file_prefix = "_";
?>
```
Create a configuration file with _ prefixed to the file name, such as in the following example:
```
# touch /opt/monitor/etc/_custom_objects.cfg
```
Add the configuration file to the list in /opt/monitor/etc/nagios.cfg, below the other cfg_file variables:
```
cfg_file=/opt/monitor/etc/_custom_objects.cfg
```
Restart OP5 Monitor.
```
# mon restart
```

You can add OP5 Monitor configuration objects to the new configuration file. They are not displayed in the configuration pages, but you can still see the objects using Manage > View active config. For more details, see View active configuration in Introduction to configuration.
