System Tags
System Tags
Watch the videoSystem Tags provide status about the Ignition system, such as memory usage, performance metrics, and so on. System Tags cannot be deleted or modified. To view the System Tags in the Tag Browser, go to the Tag Provider Selector and select System.
The System Tags folders are displayed: Client and Gateway. The scope for each is slightly different.
System Client Tags (Vision Only)β
Client-scoped System Tags provide status information about the client's system. They can be used with the Vision module for any Vision Client. Every individual client is going to have their own values, such as IP address, host name, username, and more. There are three folders within the System > Client folder: Network, System, and User. You cannot modify Client System Tags.
