## Appendix B Managing the Inventory

The Inventory pages enable you to view all currently monitored assets and delete assets which are no longer monitored or no longer present. It is also useful for debugging problems with your setup. The information in the Inventory page is read from the repository's Inventory schema, where all information about the current and historical assets is stored.

Historical assets are assets which were once monitored but are no longer used, such as servers which used to host MySQL instances but were decommissioned, or repurposed. These persist in the repository's Inventory schema and are displayed in the MySQL Enterprise Monitor User Interface even though they are no longer used.

Current assets are assets which are active and currently monitored.

## B.1 The Inventory Page

The Inventory page cannot be accessed from the MySQL Enterprise Monitor User Interface. To open the inventory page, you must edit the URL in the browser address bar. To open the Inventory page, enter the following address in your browser:

`https://ServiceManagerHost:PortNumber/v3/inventory`

Where `ServiceManagerHost` is the address of your MySQL Enterprise Service Manager and `PortNumber` is the port it listens on.

Enter the login details, if prompted to do so. The username and password are the same as those used to log in to the MySQL Enterprise Monitor User Interface.

### All Inventory

The All Inventory page displays all recorded assets, current and historical, grouped into categories.

For example, selecting `agent.Agent` opens a page listing all the agents stored in the inventory. Selecting one of those agents, opens a page listing the details of that agent. Details such as the `homeDir`, `version`, and so on.

### All MySQL Servers

The All MySQL Servers page displays all current, monitored MySQL instances. A historical record of instances is not kept. If a MySQL instance is deleted from the MySQL Enterprise Monitor User Interface, it is deleted from the inventory and is not displayed in the All MySQL Servers inventory page.

### All Hosts

The All Hosts page displays all current and historical hosts. Clicking one of the host links opens a page listing the details of that host. Details such as the number of CPUs, the filesystems and the MySQL instances, if any, installed on that host.

## B.2 Using the Inventory Page

The Inventory page enables you to view the details of all assets stored in the repository, and to delete obsolete or unused assets.

### Deleting Assets

MySQL Enterprise Monitor maintains a record, in the Inventory schema, of all assets detected. As a result, if the network topology changes frequently, the inventory and the MySQL Enterprise Monitor User Interface may contain many unused or obsolete assets. The Inventory page enables you to remove such assets, permanently.

Important

If a current asset, that is one which is actively monitored, is deleted, MySQL Enterprise Monitor rediscovers it as part of the monitoring process.

To delete an obsolete or unused asset, do the following:

1. Navigate to the asset's page.

2. Click the Delete button in the left-hand sidebar.

   A confirmation dialog is displayed, asking if you want to delete the asset.

3. Click Yes to delete the asset, Cancel to return to the asset page.

Important

To delete a host which is currently monitored, you must first, in the MySQL Enterprise Monitor User Interface, stop the monitoring Agent, delete the Agent and Instance, then delete the host using the Inventory page.
