# DLCI-Util Schema Statistics

This schema provides DLCI (data link connection) utilization statistics that can be used for monitoring and troubleshooting the following products: SGSN with CLC-type line cards
This schema provides the following types of statistics:

- Counter: A counter records incremental data cumulatively and rolls over when the counter limit is reached. All counter statistics are cumulative and reset only by one of the following methods: roll-over when limit is reached, after a system restart, or after a clear command is performed. The limit depends upon the data type.
- Gauge: A gauge statistic indicates a single value; a snapshot representation of a single point in time within a defined time frame. The gauge changes to a new value with each snapshot though a value may repeat from one period to the next. The limit depends upon the data type.
- Information: This type of statistic provides information, often intended to differentiate sets of statistics; for example, a VPN name or IP address. The type of information provided depends upon the data type.

The data type defines the format of the data for the value provided by the statistic. The following data types are used in statistics for this schema:

- Int32/Int64: An integer, either 32-bit or 64-bit: For statistics with the Int32 data type, the roll-over to zero limit is 4,294,967,295. For statistics with the Int64 data type, the roll-over to zero limit is 18,446,744,073,709,551,615.
- Float: A numeric value that can be represented fractionally; for example, 1.345.
- String: A series of ASCII alphanumeric characters in a single grouping, usually pre-configured.

IMPORTANT:

Unless otherwise indicated, all statistics are counters and all statistics are standards-based.

Key Variables: Every schema has some variables which are typically referred to as 'key variables'. These key variables provide index markers to identify which object the statistics apply to. For example, in the card schema, the card number (variable %card%) uniquely identifies a card. For an HA service, the keys would be "%vpnname%" plus "%servname%", as the combination uniquely identifies an HA service. So, in a given measurement interval, one row of statistics will be generated per unique key. The schema keys are identified in the Description section of the table.
Table 1. Bulk Statistic Variables in the DLCI-Util Schema

Variables | Description | Data Type
--- | --- | ---
card | Description: Identifies the card for which statistics are being collected. The ID is based on the chassis slot number (17-48) where the channelized line card (CLC2) resides. This is a key variable. Triggers: N/A Availability: N/A Type: Information | Int32
port | Description: Identifies the port number (1 - 4) for which the statistics are being collected and displayed. This is a key variable. Triggers: N/A Availability: N/A Type: Information | Int32
dlci_util_path | Description: Identifies a logical Frame Relay path associated with the port. Valid range is 1 to 3. Triggers: N/A Availability: N/A Type: Gauge | Int32
dlci_util_ds1e1 | Description: Identifies the type of connection, E1 or T1, associated with this path. Triggers: N/A Availability: N/A Type: Gauge | Int32
dlci_util_timeslot | Description: Identifies the timeslot configured for this E1/T1 connection. Triggers: N/A Availability: N/A Type:Gauge | Int32
dlci_util_dlci_no | Description: Indicates a specific data link connection identifier (DLCI) for which the utilization information will be displayed. Triggers: N/A Availability: N/A Type: Gauge | Int32
dlci_util_nsvc | Description: Identifies a specific network service virtual circuit (NSVC) associated with the DLCI. Triggers: N/A Availability: N/A Type: Gauge | Int32
dlci_util_nse | Description: Identifies the specific network service entity (NSE) associated with the DLCI. Triggers: N/A Availability: N/A Type: Gauge | Int32
dlci_util_dlci_curr_rx | Description: Indicates the current average number of kbps of received traffic via the DLCI. Triggers: Collects the Rx byte statistic when a message is received. Availability: per CLC2 Type: Gauge | Int64
dlci_util_dlci_curr_tx | Description: Indicates the current average number of kbps of transmitted traffic via the DLCI. Triggers: Collects the Tx byte statistic when a message is transmitted. Availability: per CLC2 Type: Gauge | Int64
dlci_util_dlci_5min_rx | Description: Indicates the average number of kbps of received traffic via the DLCI in a 5 minute period. Triggers: N/A Availability: per CLC2 Type: Gauge | Int64
dlci_util_dlci_5min_tx | Description: This gauge indicates the average number of kbps of transmitted traffic via the DLCI in a 5 minute period. Triggers: N/A Availability: per CLC2 Type: Gauge | Int64
dlci_util_dlci_15min_rx | Description: This gauge indicates the average number of kbps of received traffic via the DLCI in a 15 minute period. Triggers: N/A Availability: per CLC2 Type: Gauge | Int64
dlci_util_dlci_15min_tx | Description: This gauge indicates the average number of kbps of transmitted traffic via the DLCI in a 15 minute period. Triggers: N/A Availability: per CLC2 Type: Gauge | Int64
