System Maintenance

Using the System Maintenance Pages

You can use the System > Maintenance pages to perform the following tasks:

•Enable system maintenance options, such as software version monitoring and disk clean-up.

•Upgrade, downgrade, or rollback the system software.

•Download client installer files so that you can distribute them in out-of-band methods to end users.

•Test network connectivity between the system and servers that have been configured to be used with it.

•Display hardware status.

Configuring System Maintenance Options

You can use the maintenance options page to enable various system maintenance features.

To enable various system maintenance features:

1.Select Maintenance > System > Options to display the maintenance options page.

2.Select options as described in the following table.

3.Save the configuration.

The following table lists the System Maintenance Options Configuration GuidelinesE:

Options	Guidelines
Automatic version monitoring	If you enable this option, the system reports to Ivanti the following data: Machine identifier. Information describing your current software, including: Software build number and build name. An MD5 hash of your license settings. An MD5 hash of the internal interface IP address. If this node is in a cluster, the number of nodes within that cluster. Current state of the node. Cluster type (active/active, active/passive). Total number of unique subnets on the cluster nodes. Version of Ivanti Secure Access Client. Version of ESAP. Cluster log synchronization status. Total number of concurrent users on the device. Number of Ivanti tunnels. We strongly recommend that you enable this service.
Gzip compression	Connect Secure only. Use gzip compression to reduce the amount of data sent to browsers that support HTTP compression. This can result in faster page downloads for some users.
Kernel Watchdog	Enables the kernel watchdog that automatically restarts the system under kernel deadlock or when kernel runs low on some key resources. Enable the kernel watchdog only when instructed by Ivanti Technical Support.
Resource throttling	Enables system resource throttling in the system that gives system processes higher priority. High priority processes will get high resources under system load. Changing this option will cause a system reboot.
File System Auto-clean	Enables the system to automatically clean up the file system when disk utilization reaches 90%. The clean-up operation deletes files that might be relevant in debugging-for example, debug logs, core files, and snapshots might be deleted.
Web installation and automatic upgrade ofIvanti Secure Access Client	After you deploy Ivanti Secure Access Client software to endpoints, software updates occur automatically. A Ivanti Secure Access Client can receive updates from the server. If you upgrade the Ivanti software on your Ivanti server, updated software components are pushed to a client the next time it connects. A bound endpoint receives connection set options and connections from its binding server, but it can have its Ivanti Secure Access Client software upgraded from any Ivanti server that has the automatic upgrade option enabled. During a client software upgrade the client loses connectivity temporarily.
Enable Ivanti Secure Access Client Components removal Tool for Cert issue Remediation	Provides an option for the Admin to enable users to download the Ivanti Secure Access Client Components removal (Upgrade Helper) tool on Windows End User machines upon Browser access and remediates the certificate expiry issue. For more information, refer KB44781 and KB44810.
Virtual Terminal console	Enables the virtual terminal on a virtual appliance. Clear this check box to use the serial console. Changing this setting will restart the system.
Java instrumentation caching	Connect Secure only. Caches the Java instrumentation to improve the performance of Java applications.
Show Auto-allow	Connect Secure only. The auto-allow option provides the means to automatically add bookmarks for a given role to an access control policy, for example, Web bookmarks with auto-allow set are added to the Web access control policy. You only use this feature if you also use Resource Policies. We recommend that you use Resource Profiles instead.
Do not show Task Guidance/Help page on admin login	This option is applicable only in case there are no licenses installed. When enabled, Task Guidance/Help page does not appear automatically upon administrator login.
Clear all configuration data at this device	This option clears all keys and triggers a configuration reset and reboots the device.
Prevent system overload	Disallows user login, user login through Ivanti Desktop, HTML5 connection or connection to a web resource when the CPU load is above a certain threshold. By default, this option is disabled for Ivanti Connect Secure upgrades and enabled for new installation. Exception: Admin logins, DMI and inbound REST calls are not blocked due to CPU overload. When a login to the HTML5 connection or connection to a web resource is blocked and when a user tries to log in, the login page will display an appropriate system busy message. To configure log events for User Access, in the System > Log/Monitoring > User Access > Settings tab, select the System Too Busy check box. By default, this option is enabled. Select System > Log Monitoring > User Access > Log to view the logs.
Auto reboot the system	This option automatically reboots the system when the appliance is in kernel panic state.
Enable GRO	This option allows to enable Generic Receive Offload (GRO) on int0 and ext0 interfaces (applicable only for PSA hardware). This option is disabled by default.
End-user Localization	Select one of the following options: Automatic (based on browser settings) English (U.S.) Chinese (Simplified) Chinese (Traditional) French German Japanese Korean Spanish Italian Polish
External User Records Management
Persistent user records limit	Specify the maximum number of user records. This feature is useful when system performance is affected due to a large number of user records. We highly recommend you consult Technical Support prior to using this feature. Deleting a user record removes all persistent cookies, SSO information, and other resources for that user. It does not remove the user record from the external or internal authentication server. If you delete a user record and that user logs back in to the authentication server, new user records are created. Records are not removed if that user is currently logged in.
Number of records to delete when the limit is exceeded	Specify a number. Older records are removed first. A user record is not deleted if that user is currently logged in.
Delete records now	Check whether the persistent user records limit has been exceeded. If it is, delete the number of user records specified in the option above.
Automatic deletion of user records periodically	Check whether the persistent user records limit will be exceeded whenever a new user record is about to be created. If true, delete the records prior to creating the user new record.
