Defining Error Log Filtering

The Error Log Filtering view allows selecting which error logs generated by the SQL Server database are to be displayed in the Logs drilldown. The error log alarm increments the error log count for each error log entry that matches one of the strings listed in this view.

Foglight for SQL Server provides a default list of error logs enabled in the scanning, and allows adding, modifying, or disabling error logs from the list.

The settings defined using the Error Log Filtering view affect the following alarms: SQL Agent Error Log Summary, SQL Server Error Log Summary, SQL Agent Log Informational Error, and SQL Server Log Informational Error.

For details, see the Alarms chapter of the Foglight for SQL Server Reference Guide.

The Error Log Filtering view allows defining the following settings:

For all SQL Server versions, the Error Log Filtering view allows defining the following settings:

Display under a pre-defined name in the SQL Agent Error Logs and SQL Server Error Logs panels — using the Match List pane. This pane contains a default list of expressions within the alert logs that are to be retrieved and displayed in the Alert Log panel under a pre-defined name, category, and severity.
Exclusion from the SQL Agent Error Logs and SQL Server Error Logs panels display — using the Ignore List pane, which contains a default list of alerts that are to be excluded when setting the alert logs display.
IMPORTANT: Only messages that are explicitly defined in the Ignore List will not be displayed. Messages that were not added to either the Match or Ignore lists appear under name Other, type SQL Server errors messages and severity Informational. Therefore, ensure that messages that need not be displayed are added to the Ignore List.

Both the Match List and the Ignore List panes can be customized by adding, editing, or removing alert logs. Each filter can be enabled or disabled separately by clicking Edit and selecting or clearing the Enabled check box. Alternatively, to enable or disable all of the filters, click the Enable All or Disable All button.

Click Add.
The dialog box Add Filter appears.
Click Add to save your settings.

The entire list of filters displayed on the view can be enabled or disabled by selecting the Enable All or Disable All buttons at the bottom of the screen. Enabling a single filter requires editing it.

Click Edit.
The Edit Filter dialog box appears. Ensure that the Enable Filter check box is selected (default).
Click Set.
If another filter should be edited, repeat Step 1 to Step 4. If no more editing is necessary, or if all additional editing operations were carried out, save the changes before switching to another view. For details, see Reviewing the Administration Settings .

Configuring Performance Counters

The Performance Counters view allows configuring user-defined performance counters and their Unit of Measurement/Indicator. The counters created in this view are accessible using the User Metrics drilldown.

Each user-defined performance counter is collected and plotted over the specified time range in the User Metrics drilldown. The User Metrics drilldown 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.

Use this view to add user-defined collections of performance counters to a specified agent by selecting them from the complete list of available performance counters. The user-defined counters value refers to raw data, which is derived directly from the counter provider.

Click Add Counters at the bottom of the screen.
The Retrieving Performance Counters progress bar appears.
Click Add.
After adding all of the requested counters, click Close to exit the Add Counters dialog box.

Setting Options for Displaying Data in the Buffer Cache

The Buffer Cache view allows configuring the default retrieval settings for Buffer Cache panel, accessed through the Memory drilldown.

A lower buffer cache hit rate can be resolved by investigating the objects that consume the largest amount of cache size.

Use this view to configure the number of objects to be displayed in the table and their sorting properties.

Table 69. Click Edit in the Buffer Cache Settings section to edit the following parameters.

Defines the maximum number of objects to be displayed in the Buffer Cache panel (default: 20).

Defines whether the order of the items for retrieval is ascending or descending.

Defines the parameter by which the display is to be ordered.

After carrying out all of the requested changes, save the changes before switching to another view. For details, see Reviewing the Administration Settings .

Setting Options for Displaying Data in the Plan Cache

The Plan Cache view allows configuring the default display settings for the SQL Server's plan cache panel, accessible using the Memory drilldown.

Use this view to filter the Plan Cache panel's display, by setting criteria such as which object type is displayed, as well as the default number of records displayed and the sorting method.

Table 70. Click Edit in the Plan Cache Settings section to edit the following parameters.

Defines whether to display Adhoc SQL plans.

Defines whether to display SQL Server system objects.

Defines whether to display only objects that reside on certain databases.

When setting this parameter, the character % can be used as a wild card. For example, to display objects from all of the databases that begin with Quest (Questdatabase, QuestWorkDatabase, and so on), enter Quest%.

Defines the maximum number of objects to be displayed in the Plan Cache panel (default: 20).

Defines whether to retrieve only certain objects.

When setting this parameter, the character % can be used as a wild card.

Defines the criterion for determining the data display order.

The available criteria are as follows:

Database Name (Default) — the name of the database
Schema Name — the name of the schema
Object Name — the name of the object
Object Type — the object type
Use Count (Default) — the number of times this cache object has been used since inception
Ref Count — the number of other cache objects that reference this cache object
Cache Object Type — the type of the cache object
SQL Bytes — the size of the text
SQL Text — the SQL text
Used Date Format — the date format used by the object
Used Language — the language format used by the object
MB — the amount of space in the plan cache that is allocated to this object
% from Cache — the percentage of cache used by the object
Used MB — the size, in megabytes, used by the object type

Defines whether the display would be carried out in ascending or descending order.

After carrying out all of the requested changes, save the changes before switching to another view. For details, see Reviewing the Administration Settings .
