The Processes view shows information about batch processes performance on the Warehouse work station. The Processes table in the Main area includes the following columns:
Column | Description | ||
---|---|---|---|
Node | The specific Precise framework installation.
| ||
Technology | The name of the technology that the process gathers data for. Processes that maintain the PMDB itself are listed, but the technology column remains empty. | ||
Process | The process name is a logical name that describes the process function. For example, “Calculate Baselines.” Two types of processes gather PMDB data. One process type includes processes that are part of the PMDB FocalPoint and run on the PMDB server, such as the Summarize Data process. The other process type includes processes that are part of another product, such as the Schema Changes process in a Microsoft SQL Server instance that Precise for SQL Server monitors. These processes run on the product’s server and on the PMDB FocalPoint, which is in charge of scheduling them. See |
Product | The name of the product the process runs for. |
Last Run | The last time the process that is named in this row ran. |
Next Scheduled Run | Time when the process that is named in this row is scheduled to run again. |
Status | An icon indicating the current status of the process that is named in this row. |
The current status of a process can be any of the following statuses:
Icon | Description |
---|---|
The process is running. | |
The process completed successfully. | |
The process failed during the run. |
Under the Processes view (on the Warehouse workstation), you can run a process, view the execution history of a process, and configure the scheduling and the parameters of a process.
Anchor | ||||
---|---|---|---|---|
|
All processes are scheduled to automatically run at the set interval, but you may also manually run a process whenever required. See Process parameters.
...
You can manually configure these parameters according to the requirements of your environment. You can edit the default values or override them by defining instance-specific values. If a process does not include any configurable parameters, the Parameters button is disabled. See “About About configurable process parameters” on page 87parameters.
The following table lists all the processes that you can configure per monitored instance.

SQL Server | Load Data You can restrict the number of sessions that performance data is collected for by increasing the In MS-SQL Time value. However, this value applies to the collapsed statement, including all of its children. For example, if you set the In MS-SQL Time value to 2 and the collapsed statement includes five children that spent 1 second each in MS-SQL, this amounts to 5 seconds overall and causes Precise for SQL Server to collect the performance data for the collapsed statement, even though each child spent less than the defined 2 seconds in MS-SQL. |
