DB counters allow you to track metrics on the status, availability, usage, system performance, and resource usage of your enterprise database. DB counters require a connection to the target database using its data source name (DSN).
Only queries that return a single number value can be used to capture statistics. For examples of queries that return a single number value, see Sample SQL queries.
Complete these steps to add a DB counter:
- Verify ODBC drivers.
- Set the system DSN.
- Start Monitor Administrator.
The Connections view appears.
- Click Open on the Monitor Server application connection to which you want to add the counter.
The collection pane appears.
- In the tree view, expand the collection and monitor service to which you want to add the counter.
- Click DB in the tree view to choose it.
- Right-click DB and click Add.
- Expand DB in the tree view and click New DB.
The Config tab appears.
- Type a name for the counter in the Name text box.
Sugerencia:
For easy identification, the name should include the DSN, database name, and table name.
- Click Add Credential.
The Add Database Credential dialog box appears.
- Type a name for the credential in the Name text box.
- Use one of the following samples to add the DSN Connection:
Database authentication:
DSN=<System DSN>; UID=<User ID>; PWD=<Password>
Windows user authentication:
DSN=<System DSN>; UID=/; PWD=;
Sugerencia:
The connection string text is masked for security purposes. You can type the connection query in a text editor and paste it in the Connection text box if necessary.
- Click Add.
- Click the Select a credential drop-down arrow and choose a credential.
- Choose a sample interval from the Sample Interval drop-down menu.
Nota:
It is recommended that you not use sample intervals greater than 5 minutes for critical alerts as this can skew availability statistics. For more information, see View collection availability.
- Optionally type a description in the Description text box.
- Type a name for the SQL query in the Name text box.
- Type a SQL query in the Query text box.
Nota:
Only queries that return a single number value can be used to capture statistics. For examples of queries that return a single number value, see Sample SQL queries.
- Click Add Query.
The SQL query is added to the Query List.
- Click Test to test the counter.
The test results are displayed below the Test button.
- Click Save to save the counter.
Now you can configure alerts for the counter. You can also view and analyze counter status and metrics in the ArcGIS Monitor Server application by clicking Categories > Database.
Sample SQL queries
Only queries that return a single number value can be used to capture statistics. See the subsections below for a list of sample SQL queries that return a single number value.

The following queries return average values over a predefined period. The sample interval you choose in the Sample Interval drop-down menu needs to match the query. The following sample queries use 5-minute sample intervals:
CPU utilization
SELECT avg(value) CPU FROM v$sysmetric_history WHERE METRIC_NAME = 'Host CPU Utilization (%)' and END_TIME> (sysdate-1/(24*60)*5);
Logical_Reads_Per_Sec
SELECT avg(value) Logical_Reads_Per_Sec FROM v$sysmetric_history WHERE METRIC_NAME = 'Logical Reads Per Sec' and END_TIME> (sysdate-1/(24*60)*5);

Geodatabases in SQL Server
Some of the following queries assume a dbo-owned schema and a database name of database. Change database to your actual database name. If your geodatabase uses an sde schema, change dbo to sde.
