Technical data

You can use the wildcard characters in two ways:

• You can use a wildcard with a partial tracepoint name to specify a number of

tracepoints with similar names. For example:

"ROUTING CIRCUIT SYN-*"

refers to all ROUTING CIRCUIT tracepoints whose name begins with "SYN-".

"DDCMP LINK L*K"

refers to all DDCMP LINK tracepoints whose name begins with L and ends

with K.

"CSMACD STATION STAT-?"

refers to all CSMACD STATION tracepoints with names of the form STAT-x,

where x is a single character.

• You can use the * wildcard on its own to specify all the tracepoints of a given

entity class. For example:

"ROUTING CIRCUIT *"

refers to all ROUTING CIRCUIT tracepoints.

Note that you can use wildcards only in the last part of a tracepoint name, the

instance identiﬁer that identiﬁes a particular instance of an entity class. For

example, you could not use:

"CSMACD * *"

to refer to all CSMACD PORT and CSMACD STATION tracepoints; to do that

you would have to specify two tracepoint names:

"CSMACD PORT *"

"CSMACD STATION *"

3.5.2 Starting Detached Tracing

To start detached tracing, enter the following CTF command:

CTF> START "tracepoint-name"[,...]

You can enter several tracepoint names in the same START command, separated

by commas; alternatively, you can issue several START commands.

Each of the following examples has the effect of starting collection of trace records

from the speciﬁed tracepoints. For example, to start detached tracing of the

tracepoints on two ROUTING CIRCUIT entities named SYN-0 and SYN-1, you

could enter the command:

CTF> START "ROUTING CIRCUIT SYN-0","ROUTING CIRCUIT SYN-1"

or, using two separate START commands:

CTF> START "ROUTING CIRCUIT SYN-0"

CTF> START "ROUTING CIRCUIT SYN-1"

or, using wildcards:

CTF> START "ROUTING CIRCUIT SYN-*"

Note that this last example would start detached tracing on all ROUTING

CIRCUIT tracepoints whose name begins with SYN-, not just SYN-0 and SYN-1.
