nettl -ss TRACE

Tracing Information:

Trace Filename: /tmp/gelan.TRC*

Max Trace file size(Kbytes): 65536

Trace memory allocated(KB): 131072

Trace memory to be allocated(KB): 393216

Messages Dropped: 0

Processor ID: -1

Note that the combined trace ﬁle size used is 64MB (as buffer size = 64MB/2).

11. Terminate the tracing and logging facility.

nettl -stop

(See note for the -start option.)

WARNINGS

Although the

nettl command allows the speciﬁcation of all log classes and all trace kinds for all subsys-

tems, many subsystems do not support all log classes and all trace kinds. No error or warning will be

issued if a subsystem does not support a log class or trace kind. Refer to the product documentation of

the subsystem for information on supported log classes and trace kinds.

Tracing to a ﬁle that resides on a NFS ﬁle system can impact system performance and result in loss of

trace data. It is recommended that NFS ﬁle systems not be used to contain tracing output ﬁles.

Tracing to a ﬁle may not be able to keep up with a busy system, especially when extensive tracing infor-

mation is being gathered. If some data loss is encountered, the trace buffer size can be increased. Be

selective about the number of subsystems being traced, as well as the kinds of trace data being captured.

The

nettl and netfmt commands read the /etc/nettlgen.conf

ﬁle each time they are run (see

nettl(1M) and netfmt(1M)). If the ﬁle becomes corrupted, these commands will no longer be operational.
