dlt
The DLT process provides:
• diagnostics (system performance integrity tests) which provide information
about any device in the TMS. DLT allows other processes to request
information about any device (i.e., request telephony span status)
• logging capabilities for the hardware (including line-based logging)
• statistics and internal information about TMS devices
• an interface for call simulation
DLT is used primarily by Certified Avaya Support Personnel and programmers. To
initiate the DLT process, open a command window on the node you wish to monitor
and enter the dlt command. Connections to TRIP and TCAD are attempted: if
these connections are successful, the dlt prompt appears in the command line. For
a list of these commands, see the DLT Commands section in the Avaya Media
Processing Server Series Command Reference Manual.
log
log is the text-based utility used to display messages sent between MPS processes. It
monitors message traffic among selected VOS processes and is used for diagnostic
purposes. This utility has a command line user interface.
log is an interactive application. It accepts commands from the terminal, maintains a
history event list similar to that maintained by VSH (the MPS shell used for user
interaction with VOS processes), and allows for simplified command entry and
editing. For additional information refer to this manual’s section about vsh on page
60.
log accepts the same command line options defined for any VOS process. These
options may be used to determine the MPS with which log communicates and the
method by which the messages are to be displayed. Further, a command line option
may be used to determine the status of active logging requests when the log utility
loses the IPC connection to the remote process responsible for implementing those
logging requests. The utility is also able to log messages between processes that are
not registered with SRP.
