Viewing User-defined Performance Counters and Collections

The User-defined drilldown displays Performance Counters and Collections, plotted over the specified time range.

This feature is only supported for monitored SQL Servers running on Windows platform.

This section covers the following key areas:

Viewing User-Defined Performance Counters

The Performance Counters dashboard allows viewing the customized performance counters, which were created using the Performance Counters view in the Databases Administration dashboard, plotted over the specified time range. Upon entering this dashboard, each user-defined performance counter is displayed on a separate row, with a counter that displays its current count. To view a user-defined performance counter, click the arrow on the right side of the counter.

The Performance Counter pane appears, containing the following sections:

  • Current — displaying the user-defined performance counter’s current value of the selected counter unit (for example, second).
  • History — displaying the performance counter’s significant values in the specified time range:
    • Max — the counter’s maximal value of the selected counter unit. -Avg — the collection’s average value of the selected counter unit. -Min — the collection’s minimal value of the selected counter unit.
  • Chart — provides a visual representation of the performance counter’s activity during the specified time range.

    The User Metrics dashboard is used only for displaying the user-defined performance counters; any creation or management operation of these counters is carried out using the Performance Counters view in the Databases Administration dashboard.

Viewing User-Defined Collections

The Collections dashboard allows viewing the customized collections, which were created by means of the Userdefined Collections view in the Databases Administration dashboard, either during the last sample (Last Snapshot) or plotted over the specified time range (Selected Period). This dashboard comprises the following sections:

  • The Collections column, on the left of the dashboard — displays the names of all existing user-defined collections.
  • SQL text grid — displays the text of the user-defined SQL query. By default, this grid displays the query’s short text. To display the query’s full text, click View full text (a toggle).
  • The collection details table — displays all fields contained in the query. Each of the table’s columns shows the field’s display name, while each row represents the records taken at each sample.

    The User-defined > Collections dashboard is used only for displaying the user-defined collections; any creation or management operation of these collections is carried out by means of the User-defined Collections view in the Databases Administration dashboard.
