To apply a filter

  1. In Operations Control Management Console, expand the console tree.

    OCMC console tree

  2. Right-click in the tag list in the details pane and select Filter. The <item name> - Filter dialog box appears.

    Analog tag filter

  3. Select Enable Filter.

  4. In the Tagname Like box, type the filter string. The maximum length of the filter string is 100 alphanumeric characters.

    When filtering tags, use the percentage sign (%) as a wildcard character for any portion of the filter. For example, "SysDate%" or "SysPerf%ThreadCount."

    Case-sensitivity for the filter depends on the SQL Server settings. If the SQL Server is case-sensitive, then the filter is case-sensitive; if the SQL Server is case-insensitive, then the filter is case-insensitive. Also, the string you use is not validated.

  5. Click OK.

The details pane refreshes automatically. The word "Filtered" appears in the bottom right corner of the details pane along with the number of tags that matches the filter string.

The filter remains in effect until you disable it or remove it, even if you close the Operations Control Management Console without saving your changes to the .msc file.
