HP-UX Reference (11i v1 05/09) - 1M System Administration Commands N-Z (vol 4)

nettl(1M) nettl(1M)

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 informa-

tion 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.
