Interface Diagnostics Configuration

A particular Scan Class‟s [UI_SCBVRATE] point indicates the number System Digital State
values that the interface has collected.
The Interface updates the value of a [UI_SCBVRATE] point after the completion of the
associated scan.
Although the ICU allows you to create the point with the suffix “.sc0”, this point is not
applicable to this Interface.
[UI_SCSCANCOUNT]
You can create a [UI_SCSCANCOUNT] Health Point for each Scan Class in this Interface.
The ICU uses a tag naming convention such that the suffix “.sc1” (for example,
sy.st.etamp390.E1.Scan Class Scan Count.sc1 ) refers to Scan Class 1, “.sc2”
refers to Scan Class 2, and so on.
A particular Scan Class‟s [UI_ SCSCANCOUNT] point tracks the number of scans that the
interface has performed.
The Interface updates the value of this point at the completion of the associated scan. The
Interface resets the value to zero at each performance summary interval.
Although there is no “Scan Class 0”, the ICU allows you to create the point with the suffix
“.sc0”. This point indicates the total number of scans the interface has performed for all of its
Scan Classes.
[UI_SCSKIPPED]
You can create a [UI_SCSKIPPED] Health Point for each Scan Class in this Interface. The
ICU uses a tag naming convention such that the suffix “.sc1” (for example,
sy.st.etamp390.E1.Scan Class Scans Skipped.sc1 ) refers to Scan Class 1, “.sc2”
refers to Scan Class 2, and so on.
A particular Scan Class‟s [UI_SCSKIPPED] point tracks the number of scans that the
interface was not able to perform before the scan time elapsed and before the interface
performed the next scheduled scan.
The Interface updates the value of this point each time it skips a scan. The value represents
the total number of skipped scans since the previous performance summary interval. The
Interface resets the value of this point to zero at each performance summary interval.
Although there is no “Scan Class 0”, the ICU allows you to create the point with the suffix
“.sc0”. This point monitors the total skipped scans for all of the interface‟s Scan Classes.
[UI_SCPOINTCOUNT]
You can create a [UI_SCPOINTCOUNT] Health Point for each Scan Class in this Interface.
The ICU uses a tag naming convention such that the suffix “.sc1” (for example,
sy.st.etamp390.E1.Scan Class Point Count.sc1 ) refers to Scan Class 1, “.sc2”
refers to Scan Class 2, and so on.
This Health Point monitors the number of tags in a Scan Class.
The Interface updates a [UI_SCPOINTCOUNT] Health Point when it performs the associated
scan.
Although the ICU allows you to create the point with the suffix “.sc0”, this point is not
applicable to this Interface.
