Configure Garbage Collector

Configure the Garbage Collector (GC) to discard nodes, assets, and links that are no longer useful, saving system resources.

Clean up old ghost nodes

Product Guardian
Syntax conf.user configure vi gc old_ghost_nodes <seconds>
Description

Set the threshold after which idle nodes that are also not confirmed and not learned are discarded by the Garbage Collector (GC).

Note: in Adaptive Learning, the GC works also if nodes are learned, since they all are.

Note: The GC will not remove nodes that Smart Polling created.
Parameters seconds: Number of seconds after which cleanup occurs (the default is 3600, the equivalent of one hour).

Clean up old public nodes

Product Guardian
Syntax conf.user configure vi gc old_public_nodes <seconds>
Description

Determines how long to keep public nodes that are inactive. Expressed in seconds.
Parameters seconds: Number of seconds after which cleanup occurs (default is 259200, the equivalent of three days).

Clean up old inactive nodes

Product Guardian
Syntax conf.user configure vi gc old_inactive_nodes <seconds>
Description

Determines how long to keep nodes that are inactive. Expressed in seconds. Inactivity is calculated as the difference between the current time and the last activity time.

Note: When a node that has been deleted by the GC appears again in the network it will be considered new, as a consequence, according to the learning mode, an alert could be raised. For a better result, use Adaptive Learning and choose a reasonably long interval for this setting. In some cases, such as during certain data integrations or when data originates from Smart Polling, last_activity_time may be set to 0. In these situations, garbage collection uses the created_at time instead.

Note: The GC will not remove nodes that Smart Polling created.
Parameters seconds: Number of seconds after which cleanup occurs (by default it's disabled).

Clean up old inactive links

Product Guardian
Syntax conf.user configure vi gc old_inactive_links <seconds>
Description

Determines how long to keep links that are inactive. Expressed in seconds. Inactivity is calculated as the difference between the current time and the last activity time.

Note: When a link that has been deleted by the GC appears again in the network it will be considered new, as a consequence, according to the learning mode, an alert could be raised. For a better result, use Adaptive Learning and choose a reasonably long interval for this setting. In some cases, such as during certain data integrations or when data originates from Smart Polling, last_activity_time may be set to 0. In these situations, garbage collection uses the created_at time instead.
Parameters seconds: Number of seconds after which cleanup occurs (by default it's disabled).

Clean up old ghost links

Product Guardian
Syntax conf.user configure vi gc old_ghost_links <seconds>
Description

Determines how long to wait before removing inactive ghost links. A ghost link is one that has not shown any application payload since its creation. This could be a connection attempt whose endpoint is not responding on the specified port; or it could be a link with a successful handshake but without application data transmitted (in this case, transferred data would still be greater than 0).
Parameters seconds: Number of seconds after which cleanup occurs (by default it's disabled).

Clean up old inactive variables

Product Guardian
Syntax conf.user configure vi gc old_inactive_variables <seconds>
Description

Determines how long to keep variables that are inactive. Expressed in seconds. Inactivity is calculated as the difference between the current time and the last activity time.

Note: When a variable that has been deleted by the GC appears again in the network it will be considered new, as a consequence, according to the learning mode, an alert could be raised. For a better result, use Adaptive Learning and choose a reasonably long interval for this setting.
Parameters seconds: Number of seconds after which cleanup occurs (by default it's disabled).

Clean up old sessions

Product Guardian
Syntax conf.user configure vi gc sessions_may_expire_after <seconds>
Description

Determines how long to wait before a session is considered stale and it's resources may be collected. Expressed in seconds.
Parameters seconds: Number of seconds after which clean up may occur. By default, set to 100 seconds.

Clean up old nodes that have private MAC addresses

Product Guardian
Syntax conf.user configure vi gc nodes_with_private_mac <seconds>
Description Determines how long to keep inactive nodes that have private media access control (MAC) addresses, expressed in seconds.
Parameters <seconds>: Number of seconds after which clean up occurs (by default it's disabled).
Where CLI

Preserve nodes with imported fields and manual edits

Product Guardian
Syntax conf.user configure vi gc keep_imported_nodes <value>
Description Determines whether nodes having imported fields may be considered for deletion. By default they are not (so, explicitly, if a node has a field that was imported or manually edited, it won't be automatically garbage-collected).
Parameters If <value> is 0, the rule is de-activated. If <value> is 1, the rule is activated (the default behavior).
