Configuring WarehousePG Enterprise Manager

After the initial installation of WarehousePG Enterprise Manager (WEM), use these configuration methods to fine-tune your settings or enable optional observability features.

Modifying settings using the WEM console

Administrators can modify operational parameters directly through the web interface. It's the most efficient way to enable features without interrupting the WEM service.

Navigate to Management > Settings and select Edit Settings.
Update the required fields, such as Prometheus URL or Exporter log level.
Select Save to apply the changes.
Restart WEM for the changes to take effect:
```
systemctl restart wem
```

Note

Some system parameters are only accessible via the configuration file.

Modifying settings manually

Edit the configuration file directly on the WEM host to edit parameters not exposed in the browser.

Open /etc/wem/wem.conf and update the required parameters. See the Configuration parameters reference for a full list of supported parameters.
Restart the WEM service for the changes to take effect:
```
systemctl restart wem
```

Note

The installer auto-generates WEM_COOKIE_SECRET and WEM_ADMIN_PASSWORD if either is blank at install time. The generated values are printed in the install output. Copy them before proceeding. Edit these values only if you want to share sessions across multiple WEM instances or set a specific admin password.

Configuration precedence and overrides

WEM prioritizes settings defined in the host environment over those in the WEM console.

If you define a parameter in the wem.conf file, that value takes precedence. Changes made in the WEM console don't override values set in the configuration file. If a change you made through the WEM console does not take effect, check the host configuration file for an existing entry.
