Monitoring SQL Server Transactions using the DTC Panel

The DTC panel provides additional data on SQL Server transactions.

DTC (Distributed Transaction Coordinator) service is an integral component of Microsoft Windows (Windows 2003 and higher versions) and is also available as part of the SQL Server installation, if a previous version of Windows is used. For details, see glossary definition of DTC .

If the server to which Foglight for SQL Server is currently connected has more than one instance running, this panel provides data regarding all instances of SQL Server on the current computer, not only the instance currently under analysis.

 
Table 51. The DTC Details chart displays data on the following aspects of DTC performance:
Data Series
Description
Aborted Transactions

The number of distributed transactions that were rolled back.

Active Transactions

The number of currently active distributed transactions.

Committed Transactions

The number of distributed transactions committed per second.

In Doubt Transactions

Transactions that have passed phase 1 of the two-phase commit operation (have committed the local transaction), and are awaiting a response from the DTC to either commit or roll back (phase 2).

Response Time Average

The average of the full time (in milliseconds) it has taken a query (select 1, by default) to get from the application to SQL Server and back.

Transactions/sec

The number of distributed transactions performed per second.

Monitoring Full-text Indexes using the Full Text Search Panel

In full-text indexing, a separate catalog is maintained that indexes each word in a database field as a separate index entry. The Full Text Search panel displays performance details for all full-text indexes on the server.

To create a custom filter for this table, use the options accessible by clicking Advanced. For details, see Components Shared by all Foglight for SQL Server Screens .

 
Table 52. The Full Text Search Service table contains the following data.
Data Series
Description
Database Name

The name of the database where the tables in the Full Text Catalog reside. Provides a unique identification of the database within a SQL Server instance.

ID

ID of the full-text catalog. Provides a unique identification across the full-text catalogs in the database.

FTC Name

The name of the full-text catalog. Provides a unique identification within the database.

Status

The status of the full-text catalog. Can have one of the following values:

•
0 — Idle
•
1 — Full population in progress
•
2 — Paused
•
3 — Throttled
•
4 — Recovering
•
5 — Shutdown
•
6 — Incremental population in progress
•
7 — Building index
•
8 — Disk is full. Paused.
•
9 — Change tracking
Index Size MB

The size of the full-text index, in megabytes, rounded to the nearest value.

Item Count

The number of items currently found in the full-text catalog.

Path

The name of the catalog directory in the file system.

Last Populated

Displays the time when the full text index was last populated; returns 0 if no population has occurred.

Table Count

The number of tables in the database that take part in the full text indexing process.

Using the HADR Drilldown

The HADR drilldown provides monitoring information regarding the disaster recovering solutions provided by SQL Server: Log Shipping, Cluster, Mirroring, and Always On.

While the data in the Log Shipping panel is available for all versions of SQL Server:

•
The Cluster panel data is only available for instances running on a cluster server.
•
The Mirroring panel data is only available for instances that have databases configured for database mirroring.
•
The Always On panel requires a SQL Server version equipped with the Always On capability (SQL Server 2012 and higher).

Monitoring the Log Shipping

Log shipping is used for setting up backup databases to take the place of a current “live” database if that database goes down. To that end, database logs that are dumped on the live database are copied to the backup server and restored on the backup database.

Monitoring log shipping requires connecting to a monitor server (which may be the live server, one of its backups, or an outside monitor that does not take place in the log shipping process). The monitoring server is used for analyzing log shipping performance.

Foglight for SQL Server monitors log shipping for the following types of errors:

•
Backup threshold exceeded — the failure to back up a database log within a set period of time.
•
Out of Sync threshold exceeded — the failure to restore a database log to a backup server within a set period of time after the log has been backed up.
For details, see Log Shipping Alarm .

The Log Shipping panel allows investigating the cause for a log shipping alarm by carrying out the tasks detailed in the following topics:

•
Tracking the Performance of Servers used in Log Shipping
•
Viewing the Log Shipping Details .
