3. 3
> Granularity
• SBS Diagnostic logs can be configured/enabled on per-shelf basis
> Conditional Logging
• Selected attributes are collected for list of mobile IMSI specified in MTX table
CDMAICC
• Usually need to collect logs on all SBS shelves to ensure all desired calls are
captured
• Normally used conditional logging for drive testing
• Caution must be taken at MTX boundaries as IMSI are removed from the
CDMAICC table when a mobile crosses the MTX boundary
> Unconditional Logging
• Selected attributes collected for all calls
• Used to get a sampling of calls
• Normally collects attributes on 8 to 12 shelves
SBS/CPDS Diagnostic Logging Overview
4. 4
> Log template must first be created and saved
• defines the attributes and how the attributes are to be logged, conditional or
unconditional, for a specified subsystem(s)
• Template is used to create actual log
> Number of logs and size of logs controlled by BSSM Log
Version Policy
• Section by Time
• creation of a new log file is determined by the age of the current log file.
When an upload occurs, the time stamp of the existing log file is compared
to the current time. If the current time is greater than the timestamp on the
existing log file by the amount defined, then a new log file is created, else
the uploaded log is appended to the existing file.
• Section by Size
• creation of a new log file is determined by the size of the current log file.
When an upload occurs, the size of the existing log file is compared to the
defined value. If the size is greater than the defined value, then a new log
file is created, else the uploaded log is appended to the existing file.
SBS/CPDS Diagnostic Log Creation

5. 5
> Log buffer fill-up behavior on an individual card is controlled
by Subsystem Log Full Behavior
• Continuous
• when the buffer is filled up, the BSSM will initiate the upload of the log
buffer. During upload, most attributes being logged will be placed in a
temporary buffer and transferred to the log buffer when uploading is
complete
• Halt
• when the buffer is filled up, logging is suspended on the card. The BSSM
operator will initiate uploading at a later time
• Wrap
• this will treat the log buffer as a circular buffer. When the buffer fills up it will
start overwriting at the beginning.
SBS/CPDS Diagnostic Log Creation
6. 6
> Conditional logging datafill on MTX
• After MTX login, type
• >CDMAICC
• To add an IMSI to CDMAICC table for conditional log, type
• >ADD <IMSI> on on off
• Example: ADD 450052081000153 on on off
• To check the IMSI in table, type
• >list all
SBS/CPDS Diagnostic Logging Process
9. 9
> Creating SBS Log Templates
• Start the GUI, from UNIX command line prompt type buinavapp
• Expand the Tree with the right mouse button, and select element
SelectorSubsystem1
• Entire path structure for the SBS shelf selector card subsystem is:
CBS1SBSs1 SBSCSubsystem1 Root1 SBS1 SelectorSubsystem1

SBS Diagnostic Logging—GUI
> Saving SBS Log Template
• Use names that identify both the logging task & the shelf or shelves
logged
16. 16
SBS Diagnostic Logging—GUI
> Creating SBS Logs
• Specify the Log Name, template to use, and log creation
parameters (size/time, conditional / unconditional)
17. 17
SBS Diagnostic Logging—GUI
> Starting SBS Logs
• SBS Log can be started from
the Log Template Editor and
Log Management in the GUI
18. 18
SBS Diagnostic Logging—GUI
> Suspending SBS Logs
• SBS logs must be suspended
first, before uploading data is
possible. Stopping the log will
result in a loss of any data
remaining in the selector card.
19. 19
SBS Diagnostic Logging—GUI
> Uploading SBS Logs
• Only Suspended Logs can be
Uploaded, uploading takes
the remaining log data in the
selector card 0.5 Mb buffer
and copies it to the log file on
the BSM.

SBS Diagnostic Logging—GUI
> Deleting SBS Logs
• After downloading all the log
file to local PC, the log file
can be deleted.
22. 22
> Creating SBS Log Command Line Scripts
• Open the Excel file “SBSLog_ScriptGen.xls” comes with CROS
• Datafill the log name, logging type, attributes to be logged, log file
size, number of log files… Also datafill the shelves to be logging in
spreadsheet “SBS Shelves”.
• Click button “Generate CLI Script”, 6 script files will generated in
Output script folder
• In spreadsheet “Log Attributes” contains all log attributes name,
type number, sequence number and description
SBS Diagnostic Logging—Command Line
23. 23
> Uploading all 6 script files to active BSM
• Need to do dos2unix for script files in BSM!!!
• From UNIX command line prompt type dos2unix filename filename
> Entering command line mode on BSM
• From UNIX command line prompt type cliapp
SBS Diagnostic Logging—Command Line
25. 25
> After the log starting, check the log status, make sure all
shelves log status are “Active”. The log file can be seen under
directory:/opt/bsm/log
> After DT finished, suspend the log and log status change to
“Suspended”. When upload the log and the log status change to
“UploadInProgress” then “Ready”.
> When all log status change to “Ready”, go to directory
/opt/bsm/log and combine all shelves log file into 1 file.
• htc1cems2% cat ATP* > sbslog20070511.sbs
> Or don’t want to combine the file into 1 file
• htc1cems2% tar –cvf sbslog20070511.tar ATP*
• htc1cems2% gzip sbslog20070511.tar
> After downloading above file to local PC, run “Deleting Log”
step. Don’t move (mv) or delete (rm) log files!!
> In next time to start the log, just begin with “Creating Log” steps

CPDS Diagnostic Logging—GUI
> Select desired Loggable Attributes
1.Type in Template Name
2.Select the MO for Logging
3.Select Attribute Name
4. Click Add
5. Attribute path name appears below
33. 33
SBS Diagnostic Logging—GUI
> Creating CPDS Logs
• Specify the Log Name, logging NE (Multi card selection by holding
CTRL key), then push the button “Assign”
34. 34
CPDS Diagnostic Logging—GUI
> Starting CPDS Logs
• CPDS Log are created first time with status “INITIALIZED”.
• CPDS Log can be started from the Log Template Editor and Log
Manager in the GUI
• Select the log and right click, choose “Start/Resume”
35. 35
CPDS Diagnostic Logging—GUI
> Suspending CPDS Logs
• CPDS logs must be suspended first, before uploading data is
possible. Stopping the log will result in a loss of any data remaining in
the DSFP card.
36. 36
CPDS Diagnostic Logging—GUI
> Uploading CPDS Logs
• Only Suspended Logs can be Uploaded. Uploading takes the
remaining log data in the DSFP card buffer and copies it to the
log file on the BSM.
37. 37
CPDS Diagnostic Logging—GUI
> Deleting CPDS Logs
• Only “READY” Logs can be deleted. Deleting will delete the log in
the log manager and the log file under directory /opt/cems/log.
38. 38
CPDS Diagnostic Logging—GUI
> Flush CPDS Logs
• Only Suspended Logs can be Flushed. Flushing will erase the
remaining log data in the DSFP card buffer and erase the data in
log file under directory /opt/cems/log. But log will keep in the log
manager.
40. 40
> CPDS diagnostic log template
• Log template can NOT be created in CPDS command line mode.
The log template has to been built in C-EMS GUI
> Entering command line mode on C-EMS
• From UNIX command line prompt type cemscli
• Checking log status command line must be run under Generic Card,
for example DSFP or PCU card.
• Enter DSFP card NE in command line by type
• > cd Network.1:SubNetwork.1:eBSC.1:eBSCShelf.1:DSFPCard.10
CPDS Diagnostic Logging—Command Line
43. 43
> After the log starting, check the log status, make sure the log
status are “Active”. Also the log file are available under
directory:/opt/cems/log
> After DT finished, suspend the log and log status change to
“Suspended”. When upload the log and the log status change to
“Uploading” then “Ready”.
> When all log status change to “Ready”, download the log file to
local PC.
> Before next time to start the log, run the steps (a)Starting Log,
(b)Suspend Log, (c)Flushing Log. The Flushing will erase the log
data in the DSFP card buffer and erase the data in log file but
keep the log in the C-EMS. Don’t move (mv) or delete (rm) log
files!! Then begin with “Starting Log” steps for next drive test.
> The default log template defines1 day section of time and 1
section file. If uploading the log file happened after 24hrs, keep in
mind change those 2 numbers >1
