Summary
Opens a
object, which causes all the monitor
points in the monitor set to be instantiated
.
You should not open a monitor set in the same explicit
transaction in which it was created, or in which monitor
points were added to it. For more information on using
transactions with LNS, see Programming an OpenLNS
Application in the OpenLNS Programmer’s Guide.
You can enable monitoring with the Enable method after
opening a monitor set, if the doEnable element was set to
False. You can disable monitoring using the Disable method.
If you set the doEnable element to True when you invoke this
method, the client application will be notified of the enabling
of each monitor point in the set via the Object Server's
OnNvMonitorPointEvent and OnMsgMonitorPointEvent
events. This applies to both temporary and permanent
monitor sets.
If you create a permanent monitor set while the network
management mode is set to
lcaMgmtModeDeferConfigUpdates (1), you must change
the management mode to
lcaMgmtModePropagateConfigUpdates (0) before
opening the monitor set. You can change the network
management mode by writing to the value of the MgmtMode
property of the System
object.
Note: You cannot open a monitor set while in engineered
mode. In addition, this method does not apply to MonitorSet
objects that were created as temporary monitor sets. All
temporary MonitorSet objects are opened automatically as
soon they are created. You can create temporary MonitorSet
objects with the CreateTemporaryMonitorSet method.
Availability
Local, full, lightweight, and independent clients. Note that
temporary monitor sets are not available on Independent
