The *Server Settings* page shows the active configuration of the Litmus Edge (LE) OPC UA server. The values are read-only and come from the server's configuration file. You can check the limits and defaults the server enforces without opening a shell on the device.

The values are grouped into the following sections:

- **Connection**: How clients reach the server
- **Security**: How the server secures those connections
- **Performance & Capacity**: How much work the server allows
- **Sampling Rates**: How often the server reads and publishes values
- **Diagnostics & Logging**: What the server records about itself
- **Server Identity**: How the server identifies itself

## Why this matters

The OPC UA server enforces limits that decide what a client can do: how many sessions it accepts, how many subscriptions and monitored items it allows, and how fast it publishes. Server Settings shows those limits directly, so you can size a client design against the real numbers instead of finding a ceiling when a connection is refused. When a client behaves unexpectedly, the page also tells you in a few seconds whether the server is configured the way you assume, which rules out a whole class of causes before you open the logs.
