From YouTube: Node.js Diagnostics WG Meeting - 2019-01-23
Description
No description was provided for this meeting.
If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
A
A
B
A
A
A
D
A
A
B
I
provided
an
update
in
the
minutes.
Basically,
there
was
a
meeting
held
with
four
participants
last
week.
There's
minutes
so
I
pasted
it
in
the
link.
It's
271
the
pull
request.
Okay
and
really
the
next
steps
are
to
you
know:
do
it
outline
and
then
start
filling
in
the
sections.
The
general
agreement
was
to
start
with
the
symptoms
and
then
work
from
from
that
way
outwards.
B
There
was
some
discussion
like
should
we
should
we
start
with,
like
the
deployment
environments
like
cloud
or
or
locally
or
whatever,
but
in
the
end
I
think
we
agreed
we'd
start
with
the
symptoms
like
out
of
memory
and
so
forth.
Try
and
get
a
and
I
think
to
reach
has
the
action
to
put
together
an
outline,
and
then
we
can
sort
of
break
off
each
trying
to
pick
one
of
the
things
in
that
outline
to
start
working
on
okay.
So
it
sounds
like
progress,
sir
yep.
B
Yeah
I
don't
have
any
update
on
that
I
think
they
know
there
has
been
some
work
to
sort
of
cat
categorize.
The
the
current
state
and
there's
issues
there
and
I
think
the
next
step
is
to
figure
out
is
still
to
figure
out
like.
What's
the
next
concrete
thing
we
can
do
in
terms
of
improving
testing
or
whatever
other
things
to
move
those
up
in
the
levels,
but
I
haven't
had
a
chance
to
get
back
and
focus
on
that.
Yet,
okay,.
A
B
C
A
E
So,
there's
one
a
little
update
here,
which
is:
we
have
started
working
on
looking
into
profit,
oh
yeah
replacement
for
the
default
racing
controller.
It
didn't
go
for
yet
we're
still
in
the
experimental
experimentation
phase.
We
would
have
to
get
it
into
v8
as
in
use
it
in
d8,
first
and
then
Ali
and
his
team
will
look
into
how
to
get
that
into
no
genius
if
it
proves
to
be
a
useful
replacement.
A
C
E
A
C
F
C
E
I
think
Ally
definitely
fixed
the
worst
issues.
It's
just
that
the
default
racing
controller
is
not
scaled
for
dealing
with
long-running
processes.
So
in
the
long
term
we
want
to
switch
to
something
else
in
this
case
perfetto,
but
I
think
the
worst
threading
issues
have
been
addressed,
at
least
for
the
medium-term
good.
E
A
I
think
it's
about
I,
think
yeah
I
mean
that's
effectively.
What
I
think
people
want
is
they
want
sort
of
nodejs
network
information
surfaced
through
the
chrome
debug
protocol
and
then
into
dev
tools?
Whatever
your
debugger
is
so
I
think
the
number
of
open
questions
one
is:
does
the
existing
protocol
sort
of
map
cleanly
to
the
kinds
of
information
that
node
wants
to
display,
or
is
it
too
skewed
to
the
browser
right
so
I
think
that's
one
sort
of
thing
that
needs
to
be
answered
here
and
then
I
think.
A
E
A
B
B
E
B
E
A
F
B
E
D
E
So,
with
the
summit
away
like
only
two
months
away,
not
even
yeah.
E
A
A
And
then
so,
it
seems
like
we've
got
two
meetings
and
then
about
two
weeks
before
the
the
summit,
which
is
a
southern
thename
mm-hmm,
so
timeline
wise.
It
might
make
sense
to
try
and
have
something
you
know
maybe
most
of
like
you
know,
spit
ball
topics
by
next
week
and
then
I
think
people
can
go
in
and
we
can
talk
about
what
the
right
schedule
is
just
make
sure
these
things
are
addressed.
A
E
B
C
A
E
B
B
A
B
C
E
I
mean
if
you,
if
you
know,
people
who
might
be
willing
to
come,
that's
fine,
yeah,
I,.
A
A
E
A
C
C
E
B
F
C
A
C
G
A
C
G
E
C
F
A
Diagnostic
tracing
data-
that's
cross
language,
cross-platform
and
I
know
that
the
GCP
guys
are
interested
in
sort
of
standardizing
on
that
right
so
that,
as
people
are
building
distributed,
systems
in
specific
cloud
environments
so
and
you've
got
some
piece
of
an
application.
That's
running
it
node
and
some
other
piece
that's
running
Java
and
you're.
Then
you
know
talking
to
some.
You
know
blob,
storage
or
you're
talking
to
a
database.
A
You
can
then
have
all
these
different
components
emit
log
data,
and
then
you
can
start
correlating
this
data
from
these
different
processes
on
different
nodes,
potentially
different
data
centers
wherever
it
may
be
running
right
and
I,
think
it's
called
open
sense.
This
is
sort
of
the
variant
there's
another
one.
That's
escaping
me
and
I.
A
Think
open
census
is
a
bit
of
a
variant
off
of
some
other
thing
and
I
know
that
GCP
guys
are
interested
in
sort
of
standardizing
on
that
and
I
know
that
there's
some
folks
at
Microsoft
that
are
working
with
GCP
guys
and
how
to
sort
of
bring
that
to
a
sure,
I,
don't
know
where
AWS
is
with
it.
But
that
might
be
an
interesting
talk
in
terms
of
what
are
some
of
the
things
going
on
there
as
well
and
so
I.
Do
there.
B
C
Give
a
I
just
quickly
total,
there's
like
three
different
standards
out
there,
two
and
a
half
so
there's
open,
tracing
open
tracing
is
is
like
this
yeah
standard
standard.
Obviously,
and
then
there
is
something
called
trace
context
and
then
there's
ovum,
sensors
and
open
sensors
is
is
not
really
a
standard
per
se,
but
it's
how
it's
done
by
it
by
Google
and
it's
a
little
bit
more
kind
of
their
own
thing,
but
there's
a
lot
of
talk
about
merging
or
tracing
and
all
the
sensors
right.
C
One
thing
more:
there's
collaboration
between
the
two,
at
least
so
that's
going
on
right
now,
actually
and
really
interesting
to
follow
along
and
then
there's
in
those
traits
context.
A
trace
context
is
w3c
standard
or
it's
a
draft.
Currently
it's
not
a
final
yet,
but
it's
about
the
header
formats
of
taking
the
trace
idea
from
one
server
to
another
service
for
third
service,
and
how
are
we
supposed
to
if
you
did
a
format
defined
and
how
is
the
binary
data
format?
That's
fine!
C
A
That
sounds
like
an
interesting
talk
right
like
like
here's,
the
thing
I
think
at
some
point
you
know
and
like
I,
don't
know
and
I'm
kind
of
just
like
talking
here,
because
it's
like
raping
my
day.
Job
doesn't
have
to
just
get
in
this
game
anymore,
but
on
the
at
some
point,
it's
like
if
you're
running,
node
applications
inside
of
you
know
some
of
these.
A
These
clouds
right,
then,
and,
and
you
know,
you're
potentially
communicating
with
some.
You
know
legacy
stuff
that
you've
got
running,
that
somebody
wrote
ten
years
ago
in
Java,
or
you
know,
dotnet
or
whatever
it
is
right
like
you
need
to
be
able
to
correlate
all
of
that
stuff
together.
And
how
do
you
do
that
right,
I
think
is
an
interesting
thing
and,
and
it's
something
that
at
some
point
node
is
gonna-
have
to
have
some
kind
of
a
perspective
or
point
of
view
on
I.
A
Don't
know
that
it
necessarily
today
right
and
it
would
be
interesting
for
somebody
if
somebody
could
actually
provide
such
a.
You
know
perspective
right,
like
in
terms
of
like
oh
yeah.
You
know
this
is
interesting.
Runtime
information
to
feed
out
through
this
protocol
right-
and
this
is
interesting-
application
level
information
that
you'd
want
to
feed
out.
D
B
B
C
B
B
B
A
E
So
we
do
have
a
larger
room,
a
smaller
room
and
there's
like
well,
it's
not
really
a
hallway.
It's
like,
like
a
nice
carved
into
the
hallway
that
can
accommodate
like
ten
people,
and
we
can
also
definitely
group
people
in
two
corners
of
the
larger
room.
So
I
think
we
can
definitely
split
up
into
like
five
six
groups,
if
necessary.
Okay,.
A
B
A
I
would
think
for
like
rough
planning
exercise
that
makes
sense
like
there
would
be
like
you
know,
a
talk
on
it's
like
a
Thursday
Friday
right,
so
there
would
be
a
talk
on
like
Thursday
afternoon
or
something
and
a
talk
on
Friday
afternoon,
and
then
the
other
time
would
be.
You
know
parallel
sessions
to
go
in
detail
about
right.
You
know
some
of
the
other
topics
or
something
like
we.
G
B
G
B
Like
if
we
could
get,
you
know
ruber
to
come
the
first,
you
know,
and
they
were
like
the
sort
of
kickoff
diagnostics,
how
we
do
diagnostics
and
investigation
or
doober,
or
something
that
would
be
an
interesting
sort
of
frame.
Okay.
Now
we
understand
what
they
do
house.
You
know,
that's
some
good
context
for
all
the
other
discussions.
C
B
I'd
suggest,
maybe
you
know
we
could
we
could
ask
them
first
then,
if
that
doesn't
work
out,
I
could
ask
Dan
about
PayPal
I,
said
I
I
think
the
open
sense
is
open,
tracing
trace
contacts
that
makes
sense
to
be
like
one
of
the
working
sessions
regardless,
like
I,
don't
know
if
we
want
to
fill
one
of
the
if
we
have
to
say
two
slots
for
somebody
outside
whether
we
want
to
fill
that
with
one
of
them
or
making
one
of
the
parallel
tracks.
I
don't
know
I.
A
A
Do
we
solve
this
Enrico,
but
it
might
make
sense
inside
that
dog
to
just
you
know,
have
like
a
thing
on
talk.
You
know.
Potential
topics
for
for
presentations
and
listed
is
one
of
those
and
if
you
know,
for
whatever
reason
it's
like
it
doesn't
fit
as
a
presentation,
you
can
have
a
working
group
session,
Elmo
yeah.
C
A
A
A
You
know
you've
got
you
know,
like
hundreds
of
millions
of
you,
know,
clients
running
some
version
of
v8
right.
What
are
you
doing
to
get
diagnostic
data
about
those
things,
and
how
do
you
assess
the
quality
of
v8
right
and
what
are
you
looking
for?
What
are
the
systems
that
are
in
place
to
sort
of
enable
that
right,
that's
super,
interesting
I
think
it's
probably
at
a
scale
that
isn't
interesting
to
everybody
right,
but
it
might
be
something
that
you
know
from
a
node
perspective.
You
can
take
away
some
insights
from
that.
A
E
G
Probably
I
can
find
someone
from
Netflix
about
Java
what
I
am
Not
sure
that
I
can
convince
them
to
fly
to
melee.
But
if
it's
more
like
a
diagnostic
call
or
all
right,
that's
like
something
later
in
the
area,
then
I
think
we
can
do
that
because
the
idea
came
from
that.
We
are
working
with
the
team
performance
engineering
and,
as
you
know,
Java
is
the
main
language
for
Netflix.
So
it's
kind
of
frequent
that
we
see
what
other
teams
has
in
the
company
and
we
are
jealous
so
right.
G
B
I
mean
and
I
I
work
in
the
team
that
builds
IBM's
Java
as
well,
so
I
think
we
could.
We
could
get
people
getting
people
to
the
meeting
or
you
know
whether
we
want
to
have
like
one
of
our.
If
we
can
only
have
two
external
presentations,
whether
we
want
to
have
one
of
those
two
being
on
Java
versus
node,
when
we're
together,
I'm,
not
as
sure
but
like
doing
something
in
a
future
meeting,
seems
like
a
no-brainer
to
me.
I.
A
Agree
with
that
as
well
right,
I
think
some
of
it
is
it's
like
at
some
point.
You
know,
hopefully
there's
a
bunch
of
stuff
that
are
proposed
agenda
topics
yeah,
it's
a
question
of
like
going
through
and
figuring
out
how
they
fit,
and
once
you
do
that
you'll
know
if
you've
got,
you
know
room
for
you
know
you
know
two
presentations
or
four
or
maybe
you
can
do
a
couple
of
you
know
like
I,
don't
know
lightning
talks
or
like
15-minute
I'm
gonna
run
through
something
really
quick
and
right.
There.
A
F
B
A
B
It
sounded
like
Thomas
could
reach
out
to
to
uber,
because
if
they're
close
enough,
you
know-
maybe
that's
the
closer
somebody
is
easier.
It
is
I
think
that
might
be
interesting.
So
if
you
know
my
suggestion
might
be,
Thomas
reaches
out
to
burr.
First,
if
that
looks
promising,
we
pursue
that.
If
not
I
could
try
PayPal
through
dan
and
I,
don't
know
it
or
if
it
you
know,
somebody
has
the
the
gaming
industry
or
other
ones
that
we
think
are
really
hot.
You
know
really
good
candidates.
