## Software Requirements for the Applications Manager Plug-in
Please refer to this [link](https://www.manageengine.com/products/applications_manager/help/system-requirements.html#softwareRequirements) for the recommended software requirements for installing and running the Applications Manager plug-in setup.

Alternatively, you can also install the APM Plugin manually for offline users by following the steps mentioned [in this link](https://www.manageengine.com/products/applications_manager/help/installing-apm-plugin.html).

## Auto-discovery in Applications Manager Plugin
APM Plugin helps you to discover and monitor servers and their corresponding applications automatically from OpManager during initial startup. Auto-discovery in plugin offers various configuration options that include disabling discovery, limiting the number of applications added, and prioritizing specific applications. To learn more, visit [Plugin discovery.](https://www.manageengine.com/products/applications_manager/help/auto-discovery-apm-plugin.html)
**Note:** Auto-discovery occurs only upon initial startup of APM Plugin for Trial and Professional Edition users in Windows.
## User Management in Applications Manager Plugin

To view Applications Manager plugin user profiles, navigate to **Apps → Settings → User Management**. You will be taken to the **User Management** dashboard, where there are 5 tabs - **Profiles, User Groups, Permission, Views** and **Account Policy**.
**Profiles:** You will be able to view the list of user profiles available here. However, you would not be able to click or edit the user profile details such as User Name, Update Password, E-Mail, and Role.
**User Groups:** You can add user groups and associate users to them here.
- Specify the User Group name.
- Select the users to be associated to the group.
- Select the monitor group to be associated to the user group.
- Click **Create User Group** to finish.
**Permissions:** A set of **Admin, Delegated Admin, Operator, User** and **IBM i permissions** are given from which you can enable/disable the ones that are applicable to your infrastructure.
**Views:** Select how you view the monitors in the **Home** tab. You can choose between "*Show the subgroups from the corresponding top level Monitor Group*" and "*Show the associated subgroups directly in the home tab itself.*"
**Account Policy:** Option to Enforce account lockout is given here wherein you can specify the number of continuous failed login attempts and idle session timeout (in minutes) after which the account should be locked.
## Configuring failover for Applications Manager Plugin
To ensure high availability of the APM Plugin, a secondary server can be configured to act as a failover instance. This setup involves pointing the secondary APM Plugin server to the same database as the primary server. Follow the steps below to configure failover:
- Install the secondary APM Plugin in the server where the secondary OpManager (OPM) instance is installed.
- Navigate to the installation directory of the secondary server and open the **Plugin.properties** file located at: ***/conf/Plugin.properties***.
- Ensure the value of **APM_DBNAME** matches the database name used by the primary Plugin server.
- Save any changes made to the **Plugin.properties** file.
- Start the OPM secondary server.
**Note:**
- Ensure that the secondary Plugin server is compatible with the primary Plugin server's version.
- **The secondary Plugin server should not be directly started using the script file.** OpManager controls the the start and stop of the APM Plugin secondary server.
Since APM Plugin uses the same database server as OpManager, it is sufficient to configure failover the OpManager database server alone. To learn how to configure failover for the OpManager database server, [refer here](https://www.manageengine.com/network-monitoring/help/configure-failover-new.html).
