Accessing The Data Collected - Nortel DMS-100 Series Maintenance Manual

the footprint area and the address of the last used buffer. Maintenance
personnel can use this data if the SMS cannot return to task level. If the
SMS cannot return to service, the read-only memory (ROM) firmware
dumps the data.
An audit unlocks a buffer after 24 hours to prevent the loss of data from
additional SMS outages. The system produces a PM189 log when the active
buffer locks or frees.
The following examples show the type of information that the system
collects:
1 The system stores every command that enters from PMDEBUG. The
stored commands determine if a dangerous command that the user
entered causes an SMS outage.
2 The system records the start and completion of a patch applied or
removed. This record determines if the incorrect application or removal
of a patch causes an SMS outage.

Accessing the data collected

To select the classes of data to collect, use PMDEBUG. To access the data
that the tool collected, use PMDEBUG. At the top level, the BIGFOOT
command allows access to commands to select and display data. Refer to
PMDEBUG User Guide, Technical Assistance Manual, TAM-1001-004.
The Bigfoot utility stores information on diagnostics that passed and failed.
The system implements feature AF5008, XPM REX Control and Trouble
Notification Improvements. The Bigfoot utility maintains information on
error logs that occurred as a result of diagnostics that failed. The
maintenance of failed diagnostics enhances debugging attempts. The
diagnostics code maintains results graphs for each set of diagnostics that
runs. The results graph contains data on each diagnostic test in a diagnostics
run. The results graph identifies a diagnostic as passed, failed, not run, or
test not defined. Page 8–8 presents an example of the diagnostics graph.
The three main sublevels for these functions follow:
1 A selection menu is available to select, delete, and query the classes of
events to capture.
2 A HEX DUMP command displays the collected data in hexadecimal
format. The system does not interprete the data. The hexadecimal
format displays the data or helps loads that do not have the decoding
routines.
3 A dump routine displays formatted data. The system displays the
hexadecimal format if a formatting routine is not present.
