3.5.1 Tracepoint Names
A tracepoint is usually associated with a particular network management entity,
and has a name that is either identical or similar to the entity name. See the
DECnet/OSI Network Management manual for a description of the structure of
entity names.
For example, the Routing module contains tracepoints for each ROUTING
CIRCUIT entity that is created; such a tracepoint would have a name like:
"ROUTING CIRCUIT SYN-0"
where SYN-0 is the name of a particular ROUTING CIRCUIT entity. Another
example of a tracepoint name, this time in the CSMA-CD module, would be:
"CSMACD STATION THIS-STATION"
where THIS-STATION is the name of a particular CSMACD STATION entity.
Tracepoint names must always be enclosed in double quotes when they appear in
CTF commands.
Note that not all tracepoints correspond to network management entities, and
therefore not all tracepoints have names that correspond to entity names (see
Appendix B for examples of VAX P.S.I. tracepoints whose names do not correspond
to X.25 network management entities). Also, not all network management
entities have tracepoints associated with them. See the appendixes to this
manual for a list of the tracepoints provided by the networking products that
support CTF.
The tracepoint names given above are all local tracepoint names. Remote
tracepoint names are similar, but must begin with a node name. Also, since the
CTF object on remote servers is usually protected by a user name and a password,
remote tracepoint names must usually include this access control information as
well.
For example:
NODEA"FRANK CHICKENS"::"CSMACD STATION THIS-STATION"
specifies a tracepoint on the remote server with the node name NODEA,
specifying user name FRANK and the password CHICKENS. The portion of
the name after the :: is the same as for a local tracepoint name. Note that the
node name and :: in a remote tracepoint name are not enclosed in double quotes.
Some more examples of remote tracepoint names follow:
ROUTER3"SYSUSER UNGUESSABLE_PW"::"ROUTING CIRCUIT SYN-2"
REMNODE"REMUSER FRED"::"DDCMP LINK SYN-3"
3.5.1.1 Using Wildcards in Tracepoint Names
You can refer to several tracepoints in a single CTF command by specifying
several tracepoint names, separated by commas. For example:
CTF> START "ROUTING CIRCUIT SYN-0","ROUTING CIRCUIT SYN-1"
Alternatively, you can use the wildcard characters, * (asterisk) and ?, in a
tracepoint name to make it refer to several tracepoints. The ? wildcard can
stand for any single character, and the * wildcard can stand for any string of
characters.
