(UniInt) Performance Counter Points

The Performance Counter Points page allows you to create, delete, correct and rename PI PerfMon interface performance counter points. Performance counters are available only in UniInt-based interfaces built with UniInt 3.5.0.0 and later. This section is enabled only if the selected interface meets the following four conditions:

• UniInt-based interface built with UniInt version 3.5 or later

• PI API 1.3.4 or later is present

• PI Performance Monitor interface is installed as a service and writing data to the same host PI Server as the current interface

• The currently selected interface is installed as a service on this machine

Right-click and choose a menu command to work with performance counter points:

• Choose Create to create the selected point.

• Choose Create All to create all points marked Not Created or Deleted.

• Choose Delete to delete a selected point.

• Choose Delete All to delete all performance counter points listed.

• Choose Correct to correct a selected point's definition.

• Choose Correct All to correct all points marked Incorrect.

• Choose Rename to specify a new name for the selected point.

• Choose Refresh Snapshots to update the Snapshot column for all points.

• Choose Refresh Table to reload all performance points in the table. This will refresh the Tagname column if the interface was moved from one node to another.

If a point already exists, the status is marked Created and the Delete option is enabled. If a point does not exist, the status is marked Not Created or Deleted and the Create option is enabled.

Performance counter points are created with the following PI point attribute values:

• Tag

  Point name that appears in the list box

• Exdesc

  • If the performance counter is for the entire interface:

    \\Local_node_name + \Interface_service_display_name + "(_Total)\ + Performance_Counter

  • If the performance counter is for a particular scan class in the interface:

    \\Local_node_name + \Interface_service_display_name + "(Scan Class #)\ + Performance_Counter

• Status

  The Status column in the Performance Counter Points table indicates whether the performance counter point exists for the scan class in column 2.

  • Created

  • Deleted
