Using
Lifeline
Lifeline
takes
a
snapshot
of
the
running
system
configuration,
status,
buffers,
logs,
thread
dumps,
messages,
CLI
device
configuration
commands,
device
show
run
commands,
and
so
on.
It
gathers
a
period
of
historical
network
and
system
events
that
have
been
recorded
directly
preceding
the
event.
If
required,
Lifeline
can
back
up
and
package
the
ANM
database
or
a
file
subdirectory
or
trace
and
package
a
period
of
traffic
flow
packets
for
a
specified
virtual
context.
The
following
sections
describe
how
to
use
the
Lifeline
feature:

Guidelines
for
Using
Lifeline
Lifelines
can
be
created
when
unwanted
events
occur.
Under
such
circumstances,
available
resources
could
be
extremely
low
(CPU
and
memory
could
be
nearly
drained).
You
should
be
aware
of
the
following:
•
Create
a
Lifeline
package
after
you
encounter
a
problem
that
might
require
customer
support
assistance.
The
package
is
meant
to
be
viewed
by
customer
support.
•
Lifeline
collects
debug
data
from
diagnostic
generators
based
on
priority
–
most
important
to
least
important.
When
the
total
data
size
reaches
200
MB,
t
he
collector
st
ops
collecting,
and
data
fr
om
generators
with
lower
priorities
can
be
lost.
For
details
on
content,
size,
time,
state,
and
any
dropped
data,
see
the
Readme
file
included
in
each
Lifeline
package.
•
Lifeline
collects
the
last
25
MB
of
data
from
the
file
and
truncates
the
beginning
content.
•
Lifelines
are
automatically
packaged
by
the
system
in
zip
files.
The
naming
convention
for
a
lifeline
package
is
“lifeline-yyMMdd-hhmmss.zip”.
For
example,
lifeline-07062-152140.zip
is
a
Lifeline
package
created
at
3:21:40
PM,
June
22,
2007.
•
Only
one
Lifeline
package
is
created
at
a
time.
The
system
will
reject
a
second
request
made
before
the
first
Lifeline
has
been
packaged.
•
Lifeline
times
out
in
60
minutes.
•
A
maximum
of
20
Lifeline
packages
are
stored
at
a
time.
Creating
a
Lifeline
Package
You
can
cr
eate
a
lifeline
package.
