> Per-service Session Thresholds
> Threshold monitoring can be enabled for the per-service session counts described in the following table.

> Value | Description | To configure, go to section:
> PDSN Services | Enables the generation of alerts or alarms based on the number of sessions (active and dormant) facilitated by any PDSN service counted during the polling interval. | Per-PDSN Service Thresholds
> HA Services | Enables the generation of alerts or alarms based on the number of sessions (active and dormant) facilitated by any HA service counted during the polling interval. | Per-HA Service Thresholds
> GGSN Services | Enables the generation of alerts or alarms based on the number of PDP contexts (active and dormant) facilitated by any GGSN service counted during the polling interval. | Per-GGSN Service Thresholds
> LNS Services | Enables the generation of alerts or alarms based on the number of sessions facilitated by any LNS service counted during the polling interval. | Per-LNS Service Thresholds
> GPRS Services | Enables the generation of alerts or alarms based on the number of GPRS sessions or the number of r GPRS PDP contexts (active and dormant) facilitated by any GPRS service counted during the polling interval. | Per-GPRS Service Thresholds Per-GPRS Service PDP Contexts Thresholds
> SGSN Services | Enables the generation of alerts or alarms based on the number of SGSN sessions or the number of SGSN PDP contexts (active and dormant) facilitated by any SGSN service counted during the polling interval. | Per-SGSN Service Thresholds Per-SGSN Service PDP Contexts Thresholds

> Saving Your Configuration
> When you configure thresholds they are not permanent unless you save the changes. When you have completed configuring thresholds, save your configuration as described in the Verifying and Saving Your Configuration chapter.
> Per-PDSN Service Thresholds
> Per-PDSN service thresholds generate alerts or alarms based on the total number of sessions facilitated by any PDSN service configured on the system during the specified polling interval.
> Alerts or alarms are triggered for sessions per-PDSN service based on the following rules:

> • | Enter condition: Actual total number of sessions > or = High Threshold

> • | Clear condition: Actual total number of sessions < Low Threshold

> If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.
> This section provides instructions for configuring per-PDSN service thresholding. These instructions assume that you are at the prompt for the Global Configuration mode:
> Configuring Per-PDSN Service Thresholds
> Use the following example to configure the per-PDSN service thresholds:
> configure
> threshold per-service-pdsn-sessions <high_thresh> [ clear <low_thresh> ]
> threshold poll per-service-pdsn-sessions interval <time>
> threshold monitoring subscriber
> end
> Per-HA Service Thresholds
> Per-HA service thresholds generate alerts or alarms based on the total number of sessions facilitated by any HA service configured on the system during the specified polling interval.
> Alerts or alarms are triggered for sessions per-HA service based on the following rules:

> • | Enter condition: Actual total number of sessions > or = High Threshold

> • | Clear condition: Actual total number of sessions < Low Threshold

> If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.
> Configuring Per-HA Service Thresholds
> Configure the per-HA service thresholds by entering the following command:
> configure
> threshold per-service-ha-sessions <high_thresh> [ clear <low_thresh> ]
> threshold poll per-service-ha-sessions interval <time>
> threshold monitoring subscriber
> end
> Per-GGSN Service Thresholds
> Per-GGSN service thresholds generate alerts or alarms based on the total number of PDP contexts facilitated by any GGSN service configured on the system during the specified polling interval.
> Alerts or alarms are triggered for sessions per-GGSN service based on the following rules:

> • | Enter condition: Actual total number of PDP contexts > or = High Threshold

> • | Clear condition: Actual total number of PDP contexts < Low Threshold

> If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.
> Configuring Per-GGSN Service Thresholds
> Use the following example to configure the per-GGSN service thresholds:
> configure

> threshold monitoring subscriber
> end
> Per-LNS Service Thresholds
> Per-LNS service thresholds generate alerts or alarms based on the total number of sessions facilitated by any LNS service configured on the system during the specified polling interval.

> end
> Per-GPRS Service Thresholds
> Per-GPRS service thresholds generate alerts or alarms based on the total number of attached subscribers facilitated by any GPRS service configured on the system during the specified polling interval.
> Alerts or alarms are triggered for sessions per-GPRS service based on the following rules:

> • | Enter condition: Actual total number of attached subscribers > or = High Threshold

> • | Clear condition: Actual total number of attached subscribers < Low Threshold

> If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.

> Per-GPRS Service PDP Contexts Thresholds
> Per-GPRS service PDP context thresholds generate alerts or alarms based on the total number of PDP contexts facilitated by any GPRS service session configured on the system during the specified polling interval.
> Alerts or alarms are triggered for sessions per-GPRS service based on the following rules:
