The Amazing Trace: Enhancing Distributed WebAssembly With OTEL- Brooks Townsend, Cosmonic
Have you ever looked back on a feature and wondered how you survived without it in the first place? This is exactly what OTEL did for wasmCloud, a CNCF sandbox application runtime for WebAssembly workloads on the server. As a platform focused on distributed computing, wasmCloud supports running applications on any platform, any cloud, and any edge. In such a distributed system it could be difficult to track down the source of issues, bottlenecks, and even where requests were even going in the first place. This talk focuses on the massive improvements wasmCloud saw after implementing tracing across its platform components. Aimed at reducing complexity for the developer, tracing is implemented at all stages behind-the-scenes and only requires an exporter to flip the observability switch.

I,
don't
know
if
it's
on
a
ton
of
stuff
to
show
you
today
so
I
like
to
start
off
by
saying
what
I'm
going
to
talk
about
start
with
what
is
web
assembly
and
then
talk
about
what
is
Blossom
cloud
talk
about
the
nightmare,
which
is
what
we
ran
into
with
distributed
applications
and
then
open
cylinder
tree
the
implementation
and
talk
about.
What's
next
for
us
and
what's
next,
for
you
know
what
we
see
for.
A
Before
we
get
into
this
I'm,
actually
pretty
curious,
who
has
heard
of
webassembly
before
all
right?
That's
a
pretty
good
amount.
We
just
heard
about
assembly
in
the
context
of
running
on
the
server
and
not
any
equipment.
Customer
support
I've
had
a
smaller
amount
of
people,
so
today
we're
going
to
be
talking
about
webassembly
and
on
the
server
side,
not
specifically
running
in
the
browser.
This
is
Mike.
Okay.
Is
that
fun
all
right
cool?
A
So
we
have
this
kind
of
Infamous
way
of
introducing
webassembly
as
neither
web,
and
you
know
we're
assembly,
because
what
it
what
it
started,
as
is
a
way
to
run
native
code
like
the
CE
program
in
the
browser
needed
to
be
small
needed
to
be
efficient,
needs
to
be
fast,
and
you
know
we
want
to
be
able
to
reuse
a
bunch
of
code
that
we
have
in
currency
libraries.
But
when
you
look
at
those
aspects
for
the
deployment,
Target
there's
a
lot
of
things
that
are
interesting
on
the
server
side.
A
We
want
our
services
to
be
rapidly
scalable.
We
want
them
to
be
small
and
when
I
say
small,
a
typical
web
assembly
module
is
20.
Kilobytes
to
200
300
kilobytes
and
we
want
it
to
be
secure.
We
want
to
run
and
deny
by
the
Fall
sandbox
that
gives
us
Security
in
a
way
that
a
lot
of
copy
of
the
ones
don't
leave
me
today.
There
aren't
very
many.
You
know
when
you
deploy
things
in
always
in
a
container.
A
There
are
lots
of
things
that
you
can
kind
of
tap
on
top
of
that
like
set
com
like
security
policies,
but
web
assembly
starts
that
from
the
beginning,
everything
is
done.
It's
an
open,
w3c
standard.
So
this
is
supported
by
the
same
organization
that
goes
forward
HTML,
CSS
JavaScript,
you
know
the
development
of
the
spec
is
still
supported
by
them
and
notably
is
polyglot,
so
the
the
whole
neither
went
or
assembly
is,
you
know,
first
of
all
for
when,
but
then
not
assemblies,
it's
not
really
liking.
Assembly
Language
that
you
would
write.
A
But
like
you
write
code
in
Java,
you
compile
it's
a
Java
by
code
and
you
run
that
on
the
Java
VM
right
or
what
assembly,
where
I
go
in
the
language
of
your
choice,
the
language
is
list
is,
is
constantly
growing,
you
compile
it
to
webassembly
and
you
run
it
on
a
web
assembly
one
time
so.
The
web
assembly
part
itself
is
completely
architecture
and
operating
system
foreign,
but
even
with
all
the
promise
I'll
embracing
what
I'm
saying
there
are
still
pretty
large
gaps
in
running
representatively
along
the
server
side.
A
A
So
it's
still
pretty
rough
when
you
get
down
to
trying
to
write
a
render
something
module
and
you
want
to
write
a
hello
world
right,
like
you
add,
two
numbers
can
be
really
great.
You
write
hello
as
soon
as
you
have
to
take
a
string
and
pass
a
pointer
and
a
link
to
read
an
array
of
Lights
to
print
out
a
string.
People
are
like
all
right,
I'm,
obviously
look.
This
is
not
the
thing
that
I
want
to
be
writing,
but
everything
else
is
so
complicated.
A
You
know
all
of
this
is
a
leading
up
to
what
I
and
my
co-maintainers
have
been
working
on
at
Owosso
Cloud
for
the
past
two
three
years.
The
way
that
we
see
the
modern
Computing
environment
is,
things
are
getting
smaller
and
smaller,
and
more
and
more
complexity
is
abstracted
away
from
the
developer.
A
You
know,
starting
from
everything,
tightly
double
to
a
PC
to
the
public
cloud
with
virtual
machines,
and
then
what
much
of
the
world
runs
on
today,
which
is
containers
we're
further
and
further
abstracting
things
away
and
reducing
developer
responsibility
on
these
aspects
and,
of
course,
there's
some
Nuance
to
that.
But
the
status
quo
is
you're,
not
worrying
about
the
underlying
kernel
when
you're
running
in
the
dock
ing
you
still
do
have
to
kind
of
compile
for
limits,
and
if
you
want
to
cross,
compile
like
the
new
native
us
graphic
on
instances
coming
out.
A
If
you
want
any
build
debts
before
you
do
have
to
compile
the
harm.
The
way
that
we
see
webassembly
is
that
creates
a
completely
platform
Target,
so
that
now
they
write
their
code
compiled
to
webassembly.
They
can
run
it
anywhere
and
that
reduces
their
responsibility
and
management
burden
for
people
who
are
actually
doing
devops
over
a
platform.
Work.
A
This
is
an
application
runtime.
It's
focused
on
distributed
computing,
so
running
into
webassembly
models
wherever
and
seamlessly
connecting
them.
We
actually
do
it
with
a
technology
called
Maps.
You
may
have
already
used
to
the
broker,
we're
also
abstracting
the
way
non-functional
requirements
or
what
we
call
capabilities.
So,
when
you
think
of
an
application,
you
want
to
write
like
a
to-do
application.
Your
functional
requirements.
Are,
you
want
to
create
a
degree
update
Adobe
to
do
this
right?
A
A
For
your
app
to
work,
but
it's
not
code
either.
Ultimately,
you
need
to
write
it.
Your
HTTP
server
libraries
make
sure
you're
getting
requests.
Your
key
value,
connector
the
library
that
you're
sending
sorry
sending
key
to
IU
request
back
and
forth.
These
are
open
source
projects
that
you
import
and
then
you
have
to
manage
it.
You
haven't
actually
created
that
code,
and
so
you
know
this
is
what-
and
this
actually
works
really
fine
for
a
long
time,
and
it's
not
that
complex.
A
But
when
you
see
things
like
vulnerabilities
coming
out
of
Open
Source
libraries,
when
a
vulnerability
happens
in
a
lot
library
that
isn't
your
own
in
open
source,
you
still
have
to
go
and
update
them
and
see
recompile
your
container
re-deployed,
prod
and
all
those
things
there
are
automated
tools
that
certainly
make
that
easy
easy.
It
wouldn't
be
great
to
design
like
that.
Now
I've
talked
about
website
a
little
bit
and
I'm
going
to
talk
about
velocity
cloud
and
our
five
different
layers
of
architecture
and
I'm.
A
Agnostic
aspect
of
velocity,
the
Watson
without
an
application
runs
on,
is
written
in
elixirin
thrust
and
it
kind
of
deals
with
like
the
orchestration
of
these
web
assembly
modules
and
connecting
them
to
those
non-functional
requirements
that
we
call
capabilities
and
capabilities.
This
is
kind
of
a
loaded
charm.
You
know
they're
the
people
talk
about
capabilities
and,
like
a
purely
academic
sense
like
access
to
a
single
file
or
access
to
a
single
socket
as
a
capability.
C
A
Coding,
your
you're
coding
your
application
in
terms
of
an
abstract
contract,
something
like
this
into
the
store
or
a
message
or
an
Event
Source
system,
but
you
don't
actually
mention
a
vendor.
You
don't
mention
the
runtime
implementation,
because
you
actually
indicate
that
on
your
local
machine,
you
can
code
it
with
reddits
you
deploy
to
prod
and
whatever
Enterprise
Cloud.
Whatever
you
use
that
key
Value
Store.
Instead,
it
doesn't
have
to
be
a
redstone.
It
can
be
like
an
object
store
that
implements
key
value
functionality.
A
This
is
really
important
because
the
move
from
development
to
production
is
still
a
hugely
painful
story.
I
previously
worked
at
a
really
large
company,
a
large
U.S
financial
institution
and
oftentimes
developers
are
waiting
15
minutes
in
that
development
Loop,
because
then
they
can
change
in
their
container.
They
push
the
GitHub
Jenkins
picks
it
up.
It
builds
it
deploys
the
data,
and
then
you
see,
if
you're
you
know,
code
actually
changed
right.
That's
a
that's!
A
huge
pain.
A
The
composable
actors-
these
are
our
web
assembly
modules,
where
you
implement
the
functionality
of
your
app,
and
this
is
what
developers
are
writing
and
what's
really
important
for
us,
because
that's
where
the
experience
needs
to
be
the
crisp
and
and
painless
experience,
I'll
show
you
a
little
code.
Sample
totally
know
this
song
and
the
last
part
is
the
lattice
Network.
This
is
what
kind
of
seamlessly
joins
all
of
the
country
together,
no
matter
where
it's
physically
running,
and
then
this
is
all
enabled
by
Maps
under
the
hood.
A
A
We
actually
dog
food,
our
whole
product,
I'm,
giving
another
talk
about
that
on
Wednesday
at
the
main
conference,
which
is
fine,
please
let
me
know
if
you're
interested
in
that
hope
to
see
you
there,
but
the
whole
goal
is
a
painless
experience
for
people
developing
applications
and
when
you
think
about
tracing
and
open
supplementary
and
Mattress
and
logging
those
all
fit
into
the
non-functional
requirement
piece
of
an
application.
So
you
don't
actually
need
tracing
to
run.
A
A
D
A
The
key
value
counter
this
is
your
web
assembly
module.
You
write
the
code
like
get
HTTP
requests,
return,
HTTP
response,
increment
value
and
p-value
the
actual
code,
for
this
is
going
to
look
pretty
similar
to
what
you
may
have
seen
the
light
function
of
service
offerings
because,
because
of
reactive
as
a
single
function
says,
receive
HTTP
requests
returning
HTTP
response
and
even
if
you
haven't
seen
the
rest
before,
hopefully
this
isn't
too
difficult
to
rock
you're,
getting
a
key
value.
Sender
no
mention
on
that.
A
This
is
redis
or
you
know
whatever
what
happened
to
implementation
and
you're
incrementing
it
in
the
key
Value
Store
returning
the
new
values
as
bytes.
So
we
talk
about
including
tracing
for
users
of
the
open
source
or
users
of
our
products.
We
don't
want
them
to
have
to
come
in
here
and
add
all
these
like
macros
and
then
derives
and
traits
and
things
to
just
add
a
span
or
make
sure
that
they
know
what's
happening
with
their
workloads.
A
A
B
A
Give
me
information,
and
so
to
give
a
concrete
example,
one
of
the
things
that
we
do
as
a
platform
cosmotic
Space
theme.
Is
we
open
wormholes
for
people?
You
can
think
of
this.
Like
an
interest
point.
When
people
have
like
a
second
space,
they
need
to
be
able
to
get
HTTP
requests,
so
you
open
a
wormhole
and
things
Point
into
their
Network
space.
A
So
whenever
we
do
one
of
these
things,
we
have
our
API
that
sends
the
network
request
to
a
web
assembly
module
since
another
Network
request,
or
in
other
words
to
actually
do
the
work.
Another
web
assembly
module
takes
up
that
event.
We
use
an
Event
Source
system,
but
I'm
trying
not
to
go
down
that
rabbit
hole,
and
it
actually
rejects
that
so
that
you
know
the
state
of
the
entire
system
and
when
you
look
at
something
like
this,
which
to
be
fair,
is
actually
not
even
super
complicated.
A
There
are
a
lot
of
places
that
you
get
error
timeout.
They
could
have
come
from
right
and
all
of
these
things
could
be
running
on
the
same
machine.
All
these
things
could
be
running
on
different
beams,
different
containers.
You
have
no
idea
or
something
involved,
and
so
you
know
trying
to
get
some
mileage
out
of
some
means
that
I
enjoy
lately
right,
but
getting
a
timeout
or
getting
into
over
responders
is
so
unhelpful
and
you
know,
spin
us
spend
us,
took
us
multiple
hours
of
debugging
each
time
this
happened
down
the
core
issue.
A
A
So
you
know:
I
just
put
a
screenshots
from
the
tokens
on
the
few
page
in
Elixir,
traces
are
stable
and
for
us,
traces
are
stable,
one,
simply
not
really
not
really
a
concept
of
doing
tracing
websitely
and
it's
because
what
some
of
the
modules
can't
actually
interact
with
an
outside
environment
without
exclusive
permission,
so
you
can't
make
Network
requests
export
traces
to
a
URL
or
even
read
a
file
on
disk
without
explicit
permission,
not
to
mention
that
the
web
assembly
modules
are
what
our
developers
are.
Writing
we
don't
want
them.
A
We
want
them
to
automatically
be
able
to
have
tracing
if
they
want
it
and
not
happen
in
themselves.
So,
just
a
little
bit
of
a
closer
view
into
the
host
architecture,
we
have
our
Blossom
Cloud
OTP
uhrotp
host.
That's
the
thing:
that's
kind
of
running
the
web.
Simply
we
have
implementations
of
services
call
providers,
those
are
rust
binary.
A
So
that's
actually,
you
know,
there's
great
support
for
tracing
for
us,
so
the
host
itself
in
the
trace,
the
actual
provider
room
Trace,
but
the
code
that
developers
are
writing
is
a
web
selling
module
and
can't
actually
export
that.
So
what
we
actually
did.
We
have
a
really
big
wrapper,
which
is
an
erlane
server
process
which
is
super
lightweight,
not
not
an
OS
process
that
actually
kind
of
inspired,
but
go
over
between
far
today,
so
very
lightweight
it
wraps.
A
The
webs
in
the
module,
listens
for
r1c
calls
and
traces
them
on
the
way,
and
then
the
way
out.
So
when
we
implement
this
in
the
open
source
developers
actually
get
that
tracing
for
free.
So
as
soon
as
we
implemented
it,
developers
can
flip
the
hotel
switch,
provide
an
exporter
and
they
get
all
over
both
strings,
which
is
great.
A
Going
back
to
the
you
know,
a
few
slides
this
piece
of
code.
This
is
something
a
developer
will
write.
They
upgrade
to
you,
know
Lawson
Cloud
version
50
whatever,
and
then
this
automatically
traced.
As
long
as
you
provide
an
exports,
none
of
this
code
actually
needs
to
change,
which
is
a
phone
call
of
our
home
goal,
and
how
Computing
should
be
is
that
you
know
to
change
your
non-functional
requirements.
Your
logic
shouldn't
have
to
change,
so
they
just
included
that
again
welcome
to
Hotel
Otep.
A
A
You
can
see
like
what
does
this
one
have
six
different
Services
each
change
in
color
here
is
a
network
hop
and
all
the
way
down
to
that
we
have
a
an
internal
provider
called
Sauron,
which
is
fun
and
it
kind
of
sees
everything
whatever
and
you
can
see
the
entire
flow
actually
down
at
the
bottom
of
that
one.
It's
probably
really
small,
but
you
can
that
one
has
actually
collapsed
this.
This
Trace
has
a
depth
of
81
space.
A
So
when
something
happens
you
go
and
you
you
know,
try
to
create
a
wormhole
for
yourself,
and
you
see
this,
you
get
angry,
but
when
you
have
tracing
you
can
come
back
boom.
Where
did
it
fail?
You
can
follow
the
call
stack
all
the
way
down.
You
can
see
that
this
request
failed.
He
does
what
I
know
responders
issue
with
maps,
which
means
there
wasn't
a
service.
Listening
on
the
other
side,
super
helpful
immediately.
You
can
get
down
to
the
source
of
the
issue.
A
All
right
there
it
is
wow.
This
is
the
amazing
traits.
When
somebody
comes
to
our
platform
and
clicks
login
we're
in
an
open
developer
preview,
anybody
can
come
and
sign
up
and
try
it
out.
We
provisioned
him
a
new
account
and
that
that
includes
like
giving
them
a
key
value
bucket,
giving
them
a
segmented,
Network
space.
A
You
know
setting
a
lot
of
things
up
for
them
so
that
when
they
hit
the
ground,
they
can
figure
out
Ryan,
and
this
is
a
heck
of
a
trade,
so
we're
using
honeycomb
I
think
that's
been
great
I'm,
not
saying
that
we
are
doing
everything
perfectly
as
much
as
I'm
here
to
talk
I'm
also
here
to
whatever
so
you
know,
please
feel
free
to
offers
suggestions
on
how
to
make
crazy
things
better.
But
when
you
look
at
this,
like
we're,
overflowing
the
CSS
of
this
actual
product
right,
just
the
provision
in
the
user,
so.
A
But
this
is
the
kind
of
thing
that
if
a
new
person
comes
on
to
try
our
platform-
and
they
say
hey,
my
account
didn't
like
work
like
I,
didn't
get
an
account
when
I
signed
up
who's
going
to
want
to
go
to
try
to
find
where
this
is.
We
don't
have
very
easy
all
right,
so
we
had
a
lot
of
a
lot
of
fun
with
that
I
had
it
something
that
I
feel
like
I
was
going
to
say
here
and
I
can't.
Remember.
A
Observability
is
a
little
easier
than
doing
it
later
on.
So
the
kind
of
difficulties
that
we
had
in
implementation.
You
know
I
saw
people
who
are
speaking
here
from
prafana.
This
is
not
a
fault
of
you,
I
think
I
actually
like
we
probably
missed
it,
but
we're
using
Tempo
labor
time
because
it's
free
it
has
an
open
source
container.
It's
really
easy
to
just
start
up
and
get
working
and
at
the
time
it
didn't
support
discoverable
traces
so
like
if
I
go,
do
something
and
it
fails.
A
I
had
to
go
back
in
my
logs,
find
the
trace,
ID
and
search
it
through
that,
like
I,
couldn't
actually
search
through
the
list
of
things
that
happened
recently.
But
someone
actually
came
in
from
our
community
and
said:
hey,
that's!
Who
actually
does
have
this,
at
least
in
a
newer
version,
and
so
I'm
going
to
come
back
for
before
coming
here
now
on
The
Elixir
side,
it's
actually
kind
of
surprised.
You
know
it's
all
one
kind
of
module
on
the
Rough
Side.
A
We
need
a
tracing
tracing
Futures
to
deal
with
async
away
boundaries
and
tracing
subscriber
to
deal
with
blank
formatting,
and
you
know
using
this
finding
the
correct
indications
to
use
the
different
libraries.
It
was
actually
pretty
difficult
and
when,
when
you
think
about
preserving
traces,
when
you're
going
into
async
blocks
or
tasks
that
are
pushed
off
into
the
background
is
kind
of
unintuitive
and
it
takes
very
deliberate
effort
to
do
that
correctly.
A
Another
pain
point
is
linking
spans
and
traces
together
across
Network
boundaries.
It's
difficult
across
language
batteries
fit
and
cold
and
doing
both
at
the
same
time
requires
a
lot
of
consistent
checking
effort,
especially
across
Elixir,
which
is
a
dynamically
typed
language
and
like
free
crawl
and
thrust,
which
is
a
Statin
type
and
very
strict
language.
A
So
so
linking
them
together,
like
that
Katie
Connor
app
that
I
showed
you
a
little
earlier
getting
HTTP
request.
Trace
starts
it's
a
network
request
overnight
to
go
to
the
event
friendly
module
and
then
exit
the
web
assembly
module
to
go
to
the
key
value
provider
which
is
written
in
Rust,
and
so
what
two
or
three
Network
Ops
and
two
language
boundaries
like
even
just
as
simplest
cases,
is
complicated.
Of
course
we
took
on
the
complexity
and
it
works.
It
was
just
something
that
we
had
a
photo
like
a
little
consistent
effort
into
okay.
A
A
A
Want
tracing,
they
provide
an
exporter,
they're
done,
but
there
are
legitimate
reasons
within
a
single
piece
of
code
to
want
to
add
as
well
Spanish.
We
do
it
at
the
platform
level
developers
should
have
that
control
initially,
if
that's
what
they
want
to
do
open,
Telemetry
logging
metrics
are
things
that
are
kind
of
like
an
alpha
or
implemented
stage
in
Elixir
and
rust,
and
so
that's
next
for
us.
A
As
soon
as
those
things
come
out,
we're
arguing
the
tracing
is
that
in
Long
meters
to
that
too,
and
just
to
note
I
know
that
some
products
have
kind
of
done
this
reasonably
like
they
release
a
version
of
their
products,
and
you
run
your
you
run
your
workload
using
it
or
you
want
to
use
a
new
terminal,
they're,
actually
tracing
what
you
do
and
that
can
make
people
pretty
uncomfortable
and
I
mean
it
makes
me
personally
uncomfortable
we
don't
actually
Trace
customers
or
cosmotic.
We
have
the
ability
to
like
Supply
and
explore
your
url.
A
The
next
for
us
is
allow
people
to
bring
their
own
exporter
so
that
when
they
run
their
workloads,
they
can
have
their
own
individual
things
trace
and
Export
it.
But
it's
something
that
we
actually
see
like
we
when
we're
launching
a
computer
for
them
we'll
enable
tracing.
We
don't
we
don't
like
watch
it
with
our
workloads.
Things
like
that
alerting
is
really
important.
We
love
to
set
up
alerting.
A
This
is
probably
the
capability
like
honeycomb
or
Irvine,
but
alerting
for
failed
traces
and,
of
course,
sampling
more
at
the
beginning
of
our
product
phase
and
already
generating,
like
200
million
events,
now
20
million
events
a
month,
which
is
the
time
all
right.
That
is
about
all
that
happened
so
for
personal
preferences
right
all
of
the
laws
in
cloud
is
open
source
feel
free
to
join
our
slack.
A
If
you're
interested
in
what
website
they
can
do
on
the
server
side,
come
check
it
out,
we're
pretty
proud
of
our
developer
experience
and
the
capability
providers
are
like
the
implementations
where
we
have
traces-
and
this
is
kind
of
a
final
note.
Kind
of
a
Shameless
plug
Cloud
native
awesome
day
is
today
and
my
actual
whole
company
is
here:
we're
really
excited
about
Palazzo
and
Cloud
native
we're
hosting
an
event
tonight
with
one
of
our
contemporaries
and
tomorrow
kind
of
a
web
assembly
crash
course.
A
C
D
D
A
A
The
fact
that
personality
we
needed
span
three
different
crates
is
not
ideal,
but
not
awful
right
that
there
are
other
things
that
do
that
probably
say
what
was
one
was
bad
and
ten
was
a
beautiful
place.
I
think
I
think
the
whole
experience
probably
left
us
all
at
like
a
like
a
six
or
a
seven,
the
discoverability
of
what
we
needed
to
do
specifically
around
like
a
single
weight,
which
is,
if
you
have
read,
even
if
you
have
used
for
us
as
kind
of
a
pain
point
for
the
ecosystem.
A
C
A
A
We
need
to
be
able
to
point
to
places
that
are
into
dropping
a
span
and
like
each
place
where
it
could
fail
and
attach
them
there
on.
You
know
other
than
that,
it's
just
yeah
the
feedback
from
the
community,
people
who
use
wasm
cloud
and
I
use
teasing
tracing
if
they're
like
hey
this,
isn't
really.
You
know
you
guys
have
it,
but
it's
not
really.
What
I'm
used
to
it's
history
of.
B
This
is
it
together:
I
mentioned
that
it
started
like
people,
don't
mind
how
to
write
prices
and
they
want
them
to
be
automatic,
but
we've
also
always
intentionally
written
logs
and
metrics
I'm.
Just
curious
about
like
why
people
think
that,
and
why
use
physics
and
think
that
traces
are
something
people
don't
know
we're
done,
and
they
don't
want
to
run.
A
Them
yeah
so
I'll,
maybe
is
it
okay,
there's
some
description.
Yeah,
you
know
I
kind
of
want
to
clarify
what
I'm
in
I
don't
think
that
people
don't
want
to
write
traces
I,
think
they
don't
want
to
have
to
set
up
the
entire
system
and
do
the
things
that
we
did
at
around
quickly
setting
up
a
specific
like
the
right
indication
for
phrases
to
be
exported
and
connected,
and
all
that
I
think
people
want
tracing
on
their
functions.
