Chapter 3 91

Performing Client-Server Tracing Using the Command-Line

Administration Program

To set up and control client-server tracing using the command-line

administration program, complete the following steps:

Step 1. Specify the snapadmin set_cs_trace command:

Step 2. Add the

dest_sys

parameter to the snapadmin command to specify the

client or server name for which tracing is required (this is an ASCII

string). Specifying the

dest_sys

parameter enables you to manage

tracing on messages ﬂowing between the computer to which this

command is issued and one other server on the LAN.

To manage tracing on messages ﬂowing between the computer to which

this command is issued and all other computers on the LAN, do not

specify the

dest_sys

parameter.

Step 3. Add the

trace_flags

parameter to the snapadmin command to turn all

tracing on or off, or to activate tracing on speciﬁc message types:

• To turn all tracing on or off, specify one of the following values:

ALL Tracing of all types

NONE No tracing

• To activate tracing on one or more message types, specify one or more

of the following values (use a + character to combine values):

CS_ADMIN_MSG Internal messages relating to client-server topology

CS_DATAGRAM Internal datagram messages

CS_DATA Data messages

Step 4. Add the

trace_direction

parameter with one of the following values to

indicate the direction or directions in which tracing is required (this

parameter is ignored if

trace_flags

is set to NONE):

CS_SEND Trace messages ﬂowing from the local computer

CS_RECEIVE Trace messages ﬂowing to the local computer

CS_BOTH Trace messages ﬂowing in both directions

Step 5. When you are ﬁnished adding parameters and values to the command,

press Enter.
