Transcript of ITK User Interface
Scope and Objectives
› Know what is achievable with ITK
› Use the ITK interface optimally for all possible activities
Objectives
Scope
› Data available in ITK
› Web Interface
› Views
› Command Line Tools
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

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 - 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
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
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 – 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
http://utran01.au.ao.ericsson.se/itkwiki/ViewTutorials
Itkshell
Concepts, commands, and syntax modelled on MoShell
Operates towards ITK database
All collected network MO data available
http://utran01.au.ao.ericsson.se/itkwiki/AdminGuide/NdAdmin#itkshell
Itkshell – Object Filtering
› ‘-filt’ option allow ITK object filters to be specified
http://utran01.au.ao.ericsson.se/itkwiki/ItkDr002
Command Line
Commonly used tools present on ITK server
moshell decoder lteflowfox
New releases easy to handle
flow
Network Wiki
Each network can have its own wiki
Users can create/edit content
Possibility to publish view output to wiki directly with ‘itkwikireport’
http://utran01.au.ao.ericsson.se/itkwiki/AdminGuide/WikiAdmin
Summary
› Wide range of data types
can be stored in ITK
database
› Web interface and CLI offer
powerful, customisable
mechanisms for working
with this data
