Introduction to Measurements

This section describes EAGLE measurements. Measurements provide support for:

STP performance management
SS7 traffic monitoring and engineering
Specific feature performance analysis

Measurements provide operations and maintenance personnel with network performance and STP performance data in accordance with:

Telcordia GR-82-CORE
Telcordia GR-310-CORE
Telcordia GR-478-CORE
Telcordia GR-778-CORE

Measurements can be collected and reported with the following collection methods:

The primary functions of Measurements are as follows:

Collection

Measurements are collected in 5-minute, 30-minute, and 60-minute intervals. An option exists for the default 30-minute measurements to be collected every 15 minutes. Many 30-minute measurements intervals are accumulated into daily intervals.
Storage

Measurements are stored in dedicated RAM tables and/or disks after collection. Most are retained for 24 hours. Measurements for some features are retained for 7 days.
Retrieval

Measurements data is retrieved from the RAM storage area and/or disk. ACTIVE measurement data is retrieved and reported from the application cards except for SCP SMCs. Registers collected from SCP SMCs are not supported for ACTIVE measurements and will be reported as zero in an ACTIVE measurement report. An ACTIVE linkset report requires all links in the linkset to be available in order to provide the report.

Reporting

Measurement reports are available on-demand/scheduled as shown in Table 2-1.

Table 2-1 Demand and Scheduled Reporting

Reporting Interval	Measurements Platform		E5-OAM Integrated Measurements
Reporting Interval	Demand	Scheduled	Demand	Scheduled
5-minute	Yes	Yes	Yes	Yes
15-minute (optional)	Yes	Yes	Yes	Yes
30-minute	Yes	Yes	Yes	Yes
Day-to-hour	Yes	No	Yes	No
Hourly	Yes	Yes	Yes	Yes
Daily	Yes	Yes	Yes	Yes

Scheduled measurements are directed to the Traffic Unsolicited Output Message group. No other unsolicited output is sent to this output group.

Note that the collection of measurements is a separate task from reporting. Measurements collection is activated automatically upon system power-up, or through administrative commands. Collection is organized by ENTTYPE and reporting period. Collection occurs per link every 5 minutes, and separately every 30 minutes. Measurements are generated on the application cards and periodically collected by the UI and stored for later retrieval, unless the Measurements Platform is enabled, whereas the information is collected and stored by the dedicated MPCM cards.

Refer to the Commands User's Guide for descriptions of commands used to generate, schedule, and transfer measurements reports.

Refer to the Database Administration - System Management User's Guide for information and procedures to provision basic OAM measurements, the Measurements Platform feature and E5-OAM Integrated Measurements feature.
