CreateTemporaryMonitorSet

Summary

Creates a temporary

MonitorSet

object

.

If you need monitor points that will only be used in a single

client session, you should use temporary MonitorSet objects.
Temporary monitor sets are opened automatically by

OpenLNS as they are created, and can only be accessed from

the client that created them.
When a client releases a temporary monitor set, or when the

client session in which a temporary monitor set was created

ends, the temporary monitor set and all its monitor points

are deleted.
If you need to create a group of monitor points that you can

use in multiple client sessions or that you intend to use

multiple times, you should use the permanent MonitorSet

objects described earlier in this section. However, if you do

not need to re-use a monitor set, you should use temporary

monitor sets because it takes less time and network resources

to create them.
This method is not available to Independent client

applications.
This method returns a MonitorSet object that is opened

automatically upon creation, and closed as soon as the client

session in which it was created ends. There are several other

differences between temporary and permanent MonitorSet

objects. For more information on these differences, see the

MonitorSet object.

Availability
