Data Available in ITK

Functionality

Collects and stores configuration and state data about the target network.

Node Data

Collects and stores PM counters

Handles aggregation, evaluation of formulas

Presentation of PM reports

PM Data

Collects and stores event related data:

Restarts, SW Installation & Upgrade, Alarms, System Downtimes, UEH Exceptions, UETR/CTR/GPEH, LTE Exceptions, LTE cell/UE traces

Event Data

Node Data

› Mirroring of all node Managed Objects and Attributes

› ITK-internal attributes

› Dynamic mapping between related MOs

› Schema is customisable

http://utran01.au.ao.ericsson.se/itkwiki/NodeData

PM Data

Raw counter data imported every 15 minutes

- CPP-based nodes (or other 3GPP 32.401 compliant nodes)

- AXE STS (IOG and APG)

- Coming Soon: SGSN, MME, GGSN, SASN

- Custom parsers possible

Data aggregation

- Wide range of formulas and data transformations possible

- User can supply formulas and/or custom transforms

Complex Queries

http://utran01.au.ao.ericsson.se/itkwiki/PmData

Event Data

Stores event related data in the database

Standard event types:

Restart – Program / PIU / Node

SW Install

SW Upgrade

Alarms

System Downtime

UEH Exceptions

GPEH events

UETR/CTR

LTE Exceptions

CELL_TRACE, UE_TRACE

Web Interface

Web Interface

User Menu

View Parameters

Main Menu

Available Views

Web Interface - Menus and Views

Main menu separates views into groups

Additional main menu items can be added

View hierarchy can be customised

ITK view = method to fetch and present network information

- User input

- Database fetch

- Layout of resultant charts and/or tables

http://utran01.au.ao.ericsson.se/itkwiki/UserGuide/Chapter1

Web Interface – Filters

Time filter: define time period

- Selected Interval, eg Starting 2010-03-30 and ending at 2010-05-14

- Preceding Period, eg Last 6 Hours

- Start + Duration, eg, Starting 2010-08-16 14:00 for 40 Hours

- End + Duration, eg For 3 Weeks ending at 2010-10-03

Web Interface – Filters

Object filter: define extent of objects

- Object, operator, value

- Mode button allows multiple values to be selected easily

- “Construct” icon to edit filters in text format

- Disk icon allows filters to be loaded/saved

- Recently used filters displayed in history drop-down

- “Add Attribute Filter” to filter on MO attribute values

http://utran01.au.ao.ericsson.se/itkwiki/UserGuide/Chapter2

Web Interface

User Menu

Favourites“shortcut” to views and parameters

Menu shows saved user and network favourites

Views

Views

Standard Views

Standard views delivered within ITK package

Many view requirements available by default

Dynaviews- More flexible

- eg: PM dynaview

Standard Views – PM Data

› Database queries at ROP / object level can be slow

› Aggregate data speeds this up

– Default: node, day/object, day/node– Also: busy hour, max/min values, hourly– Other custom aggregates possible– Much faster queries at coarse resolution– Automatic selection of data source

Standard Views – PM Data

Standard Views – PM Data

Standard Views – PM Data

Grouping of cells with ~ 45-60%accessibility

Standard Views – PM Data

Checking worst cells for HS RAB performance Counter to be displayed

PM Formula Handling

System formulas - Supplied with ITK package

Customised User formulas - Stored in user’s “formula file”

Local formulas- Defined for an ITK installation

- Accessible by all users

Formula definitions visible via User Menu, and Edit My Formulas

http://utran01.au.ao.ericsson.se/itkwiki/UserGuide/Chapter3

Standard Views – Node Data

› Get information on configuration of Cells, RBSs, RNCs› Get information on resource states

Standard Views – Node Data

› View information about active features

› View collected UETR and CTR recordings

Standard Views – Node Data

Standard Views – Event Data

› Identify sites with HW problems

Site identified on the basis of repeated restarts and presented together with restart

and alarm history.

Standard Views – Event Data

Upgrade SW Deployment analysis

- Success Rate

- Upgrade Durations

- Time taken to complete roll out

Upgrade failure tracking

- Paths with high failure rate

- Upgrade Steps causing failures

Standard Views – Event Data

Track System Down Time

caused by restarts

Detailed timing information about all types of restarts

- Cello Downtime (Platform Downtime)

- Application Downtime

Easily highlight restart types causing high SDT

Feed back product deficiencies to design

View Authoring

› Views are defined as XML

› Define/edit views via web interface

› Standard views can be used as templates

› Views transferable to other ITK servers

› Very powerful, with complex handling possible if necessary

http://utran01.au.ao.ericsson.se/itkwiki/ViewWritersGuide

Anatomy of a View

ITK

1) <viewparams> element defines parameters

2) <dataset> elements to define requests to be made to the server

3) <viewlayout> element contains children to place charts and tables in output
