RTT (Real-time Trace) is part of the continuous trace tool, consisting of a Lotus Sametime Unified Telephony online part and an offline part on a separate maintenance server, allowing administrators to manage Call Trace Recording and Trace File Administration (copy, compression and storage).
RTT is running continuously with the recommended default setting of 24_7_extern flags.
Use of CLI on Telephony Control Server or RTT GUI running on TM allow Continuous Tracing to be started or stopped quickly.
Parts of the RTT:
Online part on Lotus Sametime Unified Telephony:
The online part of RTT consists of the Trace Management server, the Persistent Reader, and the RTT Command Line tools.
Trace Management server
This process provides the interface between the offline Trace Manager, and the internal RTT tools
This process stores Continuous Trace data into a set of aged files, and optionally FTP or SFTP the trace data to the maintenance server. These options are controlled from the offline Trace Manager GUI through commands forwarded from the trace management server or via the Telephony Control Server CLI interface.
RTT command line tools
The existing RTT command line tools are invoked as needed by the trace management Server in response to commands received from the offline Trace Manager GUI.
Offline part on a maintenance server:
The Offline part of RTT consists of the Trace Manager GUI, Call Analyzer GUI and a Command Line Interface for the management of Continuous Tracing.
The Trace Manager GUI is able to provide control of Continuous Tracing on the Lotus Sametime Unified Telephony system.
This control will include the ability to:
Start and stop Continuous Tracing on the Lotus Sametime Unified Telephony
Setup the FTP/SFTP parameters for transferring trace data to the maintenance (MTC) server.
Start and stop the FTP/SFTP transfer of trace data to the MTC server.
Coordinate Continuous Tracing with Call Trace and RTT trace (when initiated through the GUI)
RTT is configured by default with a set of trace flags for continuous tracing. It offers commands (SSH connection):
to start/stop the continuous trace for a given time. If the stop time is set to 0 the trace will run continuously until manually stopped. The administrator may stop the continuous trace at any time.
to configure trace file copy (IP address, directory name, password, user id) and
to start/stop trace file copy via FTP/SFTP.
RTT creates trace statements when the continuous trace is started/stopped and when trace flags are changed. These actions can be initiated via the trace GUI or via the RTP CLI menu.
The trace files are always stored locally.
RTT wraps locally stored trace files (deletes oldest file if max number of files is reached, this avoids RTP alarms when disk gets full).
The administrator can invoke these commands via the RTT GUI or CLI.
System Specific Information
RTT compresses the trace files before they are written to the local disk.
If the trace file copy is active all locally stored trace files are copied to the maintenance server via the admin IP address of the Lotus Sametime Unified Telephony node and deleted afterwards.
When a non-empty trace file is 5 minutes old, it is closed and copied to the maintenance server.
RTT creates a trace statement '"xx trace statements lost" whenever trace statements could not be stored in the local trace file.
