> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

To find information about the web application and its server environment, open the **System** application and view the **General** tab.

The data is displayed for the _**administration application**_ (not the live site application). If you are running multiple administration instances in a [web farm](https://docs.kentico.com/13/configuring-xperience/setting-up-web-farms.md), the information is provided only for the instance that is serving the current user's requests.

## System information

- **Machine name** – name of the server machine on which the system is running.
- **ASP.NET account** – name of the user account used by ASP.NET in the server's operating system.
- **ASP.NET version**
- **Your IP address** – IP address from which you are accessing the system.

## Database information

Note: The database is shared by both the administration and live site application.

- **Server name** – name of the database server on which the system's database is running.
- **Server version** – SQL Server version installed on the database server.
- **Database name** – the name of the system database.
- **Database size** – the current size of the database, including the current data (the .mdf file) and the database log (the .ldf file).

> **Info:** **Contact management database separation**
>
> If the application has a [separated contact management database](https://docs.kentico.com/13/on-line-marketing-features/configuring-and-customizing-your-on-line-marketing-features/separating-the-contact-management-database.md) (on-line marketing), the page displays information for both databases.

## Memory statistics

- **Allocated memory** – size of memory allocated for the system.
- **Peak memory usage** – maximum memory used by the process.
- **Process physical memory** – physical memory used by the process.
- **Process virtual memory** – memory allocated by the process in the virtual memory space.

Click **Clear unused memory** to free up memory space by deleting unused data.

## Garbage collection statistics

Shows how many times the [garbage collector](https://docs.microsoft.com/en-us/dotnet/standard/garbage-collection/index) initiated cleaning of unused memory.

## Cache statistics

- **Cache items** – number of items stored in the application's memory.
- **Expired** – number of expired cache items.
- **Removed** – number of items removed from the system cache since the last restart.
- **Dependency changed** – number of cache items that the system dropped as a result of [cache dependencies](https://docs.kentico.com/13/configuring-xperience/configuring-caching/setting-cache-dependencies.md).
- **Underused** – number of cache items dropped earlier than the planned expiration time (possibly due to lack of memory).

Click **Clear cache** to remove all cached content from the memory of the administration application.

> **Info:** **See also**: [Configuring caching](https://docs.kentico.com/13/configuring-xperience/configuring-caching.md)

## Restarting the application

You can restart the application or its components by clicking the buttons in the header of the **General** tab:

- **Restart application**– restarts the administration application (needed to apply certain types of changes).
- **Restart all web farm servers** – restarts all [web farm servers](https://docs.kentico.com/13/configuring-xperience/setting-up-web-farms.md), including the live site application.
- **Restart windows services** – restarts all Xperience Windows services (if any are installed). See [Kentico Xperience Service Manager](https://docs.kentico.com/13/external-utilities/kentico-xperience-service-manager.md) for more details.
