Mirroring Table

The Mirroring table displays the columns listed below.

The table below provides data about the columns that appear by default in the table. For a list of additional metrics, which are hidden by default, see Additional metrics in the Mirroring table .

A number (ID) uniquely identifying a database within a SQL Server.

The database name.

The role the database takes in the mirroring process; either principal or mirror.

The name of the instance whose role in the process is principal.

The name of the instance whose role in the mirroring process is mirror.

Indicates the severity determined based on the database state: Normal, Warning, or Critical. Each of these severity level values can correspond to several mirroring states.

Normal — can correspond to one of the following mirroring states:

Warning — can correspond to one of the following mirroring states:

Critical — can correspond to one of the following mirroring states:

A state indicating the mirroring session condition. This field can have one of the following values:

The safety level at which the mirroring session is configured to work. This column indicates the level of synchronization between the two servers that take part in the mirroring process.

This field can have one of the following values:

The redo queue size. This size can be either left Unlimited or defined in megabytes (MB).

The number of warning, critical, and fatal alarms for the SQL Server database instance. When holding the cursor over one of the alarm counts, the dwell displays the most recent alarms raised against this database, sorted by severity.

Clicking this field displays the Alarms list, which is listed by severity order. See the Foglight Online Help, Monitoring System-Wide Alarms for details on the alarm information.

The metrics listed below, which are also part of the Database Mirroring collection, do not appear by default in the Mirroring table. For details on these metrics, see the Database Mirroring Collection section in Foglight for SQL Server Reference Guide.

Click the Customizer button () at the end of the table.

Viewing the Role and Data Flow of the Selected Database

The Role and Data Flow of Database section displays the mirroring operation of the database selected in the Mirroring table and its mirroring partner. The monitored instance is always displayed on the left, and the data is shown as flowing in this instance’s direction, that is: Log Received if the database is Mirror, and Log Sent if the database is Principal.

To investigate the data flow by displaying the selected database’s mirroring partner, use one of the following methods:

Click the link Investigate using the Partner’s Mirroring Page on the upper right side of the panel, above the table.

If the partner is currently monitored, its mirroring page will now be displayed. For details, see Viewing the Partner’s Mirroring Page . Otherwise, an error message is displayed, notifying that the partner server is currently not monitored.

Viewing the Selected Database's Mirroring Performance History

Clicking the Mirroring Role column of the Mirroring table displays the database’s Mirroring Performance History page, which allows carrying out the tasks described in the following sections:

The Mirroring Role pane displays the role the database played in the mirroring operation during the selected time range: Principal, Mirror, or Not Mirroring.

The mirroring role is displayed as a gauge, with each of the mirroring roles indicated by another color. Positioning the cursor over the gauge displays the percentage, within the specified time range, the database spent in each role.

The middle section of the Mirroring Performance History page includes the following panes:

Principal Counters — this pane displays a chart of the following values, which can be selected from the list on the upper left:
Mirror Counters — this pane displays a chart of the following values, which can be selected from the list on the upper left:

The Mirroring Roundtrip section displays a chart that indicates the latency of the mirroring session during the selected time range.

Viewing the Partner's Mirroring Page

When viewing the mirroring performance of a database that takes part in the mirroring operation, either as a principal or as a mirror database, it is possible to investigate the selected database’s mirroring partner, using one of the following methods:

Clicking the link Investigate using the Partner’s Mirroring Page on the upper right side of the table.

In so doing, the mirroring operation can be investigated from the point of view of the other database, thereby determining the source of the performance issue.
