The NS$instance_name: Subscriptions object provides application-level counters. These counters monitor the subscription-related activity of an application by querying the application database. Because application-level counters query databases, these counters can run on any server that hosts an instance of Notification Services.
| Counter1 | Description | Use |
|---|---|---|
Subscriptions Added |
Number of subscriptions added since the application started. Notifications sent are often proportional to the number of subscriptions. |
Use to analyze application growth. |
Subscriptions Added Per Minute |
Number of subscriptions added per minute. |
Use to determine application growth, in terms of subscriptions, over time. |
Subscriptions Disabled |
Number of disabled subscriptions. Subscriptions are disabled at the API level using nscontrol disable. |
Use to determine how many subscriptions cannot currently produce notifications. |
Subscriptions Enabled |
The total number of enabled subscriptions. Subscriptions are enabled at the API level using nscontrol enable. |
Use to determine how many subscriptions currently can produce notifications. |
Subscriptions counters are updated on a periodic basis using a performance monitoring thread hosted by the generator. The update period is specified by the PerformanceQueryInterval element in the application definition file (ADF).
After selecting a counter, select a counter instance. You can select All instances, which returns values for all subscriptions for all applications hosted by the instance, or you can select a subscription instance; the subscription instance name is a combination of the application name and the subscription class name, such as stock:stocksubscriptions.
Important
Performance counter instances are available only when the instance is running.
