Meridian Link Release 5C/CCR Release 3C Diagnostic and Maintenance Guide
Unlike message recording or monitoring, which record or display messages
flowing on a specified stream (association ID), message tracing records all
messages flowing on a link or through the system.
A link trace writes application layer messages flowing over the link to a file
with a hexadecimal format. Message dumps are labeled with time stamp,
message name, and direction of flow.
There are two levels of link traces. Trace level 0 (the default) traces all
messages; trace level 1 traces all but polling messages.
Files are recirculated every 48 hours to avoid overflowing the file system.
The default file names used by trace are as follows:
¥ For link 0: /usr/mlusr/trace/link0.trace
¥ For link 1: /usr/mlusr/trace/link1.trace
¥ For link 2: /usr/mlusr/trace/link2.trace
¥ For trace main: /usr/mlusr/trace/main.trace
Use trace link or trace main to turn on a trace. Use untrace link or untrace
main to turn off a trace.
The trace link command records all messages that are sent across a link.
Command format:
mlusr> trace link link_number [trace_level] [file_name]
The trace main command records all messages that are sent to and from the
Application Module or IPE Module regardless of link or association ID.
Command format:
mlusr> trace main [trace_level] [file_name]
