The File Editor page lets you view and edit configuration files (
.drl, and so on) in the Meridian UI instead of having to edit them in your local file system (for example, by locating the file in your
/etc directory and editing it with a text editor).
To access the file editor, log in to the web UI and click in the top menu bar.
|Changing the configuration files will affect the operation of Meridian. Incorrectly editing a file could result in features no longer working, or not working as intended.|
By default, the File Editor page displays a tree view of your OpenNMS
From this page, you can do the following:
Navigate to and open any file in your OpenNMS directory.
Expand and collapse subtrees (subdirectories).
Search for a directory name.
Search for any part of a file.
View and edit files.
To edit a file, open it on the File Editor page and type in the text box. Click Save to save your changes and update the configuration file.
|Changing configuration files on the File Editor page overwrites the file on your disk. There is currently no versioning or support for backup files. While the file editor does not have support for Git, you may want to set up your config folder as a Git repository.|
Click Reset to reload the file from your local disk into the editor.
|Reloading the file will display it as it was last saved to your disk, not necessarily the file from before you edited it.|
Depending on which file you edit, Meridian may detect and apply the configuration changes automatically. In other cases, you may need to reload a daemon or restart your instance.
The following documentation provides more information on configuration files:
To add a new file to your OpenNMS directory, navigate to a subdirectory and click Add (+). Type a name for the file, enter text in the Edit box, and click Save.
Note that validation will run on the file when you attempt to save it, and may prevent it from being saved. If an error occurs, a message at the bottom of the text editor provides more information on why validation failed.
To delete a file from your directory, navigate to a subdirectory, find the file that you want to delete, and click the minus symbol (-) beside its name. Click Confirm in the dialog that appears to confirm deletion.
|Deleting a file is permanent. The file is removed from your local disk and is unrecoverable.|
