From YouTube: TGI Kubernetes 154: Pixie
Description
Come hang out with Evan Anderson as he takes a look at Pixie, a new monitoring project being donated by New Relic. Let's dig in and figure out how Pixie relates to Prometheus and other monitoring technologies!
A
A
A
A
A
B
A
Two
two
other
things
I
thought
were
interesting:
there's
a
release,
121
webinar,
which
is
going
to
be
describing
all
the
features
in
121
from
the
folks
who
actually
ran
the
release
and
that's
going
on
later
this
week.
So
if
you're
curious-
or
I
guess
next
week-
it's
friday
and
there's
a
cap
for,
swap
that
I
thought
that
some
people
might
be
interested
in.
A
Somebody's
got
the
video
playlist
in
here.
Oh
yes,
so,
the
last
time
I
looked,
they
hadn't
gotten
it
all
into
youtube.
Yet
so
yeah
it
looks
like
here
is
the
link
to
all
the
youtube
content:
we're
not
gonna
yeah.
You
know
how
it
says,
turn
off
swap
well,
who
knows
in
a
release
or
two
we
we
might
end
up
saying
actually
swap
can
be
on.
A
Thanks
rory
yeah
kublet
cubelet
will
refuse
to
start
up
if
swap
is
on
because
it
turns
out.
If
you
move
random
pages
from
memory
to
disk,
your
performance
gets
really
unpredictable,
and
so
at
google
swap
has
been
off
for
years
and
years
and
when
kubernetes
started
up,
they
did
the
same
thing,
but
it
looks
like
some
workloads
really
benefit
from
swaps.
So
oh
awesome,
the
kubernetes
podcast
was
here
too
and
so
yeah.
A
I
thought
it
was
interesting
that
we're
going
to
be
getting
swap
on
kubernetes
and
yeah.
Let's
see
what
else
so,
yeah
kubecon
there's
the
video
list.
This
is
an
interesting
project
that
I
saw
on
twitter
and
joe
called
out
as
well.
So
kcp
is
a
prototype
of
kubernetes
without
pods
or
nodes
or
any
of
the.
I
want
to
run
code.
It's
just
an
api
server
for
those
of
you
who
might
want
to
be
able
to
write
kubernetes-like
apis,
but
don't
actually
need
to
do
pods
or
nodes.
A
A
And
then
the
it
looks
like
the
cncftoc
accepted
a
whole
bunch
of
new
projects,
so
I
figured
I'd
call
them
all
out.
Andrea
is
a
cni
that
uses
open.
What
is
it
uses
some
of
the
software
to
find
networking
stuff
and
I'm
trying
to
remember
what
is
it
called
open
v-switch,
so
it
uses
packet
level
forwarding
inside
of
the
node,
rather
than
the
some
of
the
bgp
or
other
custom
routing
protocols,
so
seemed
kind
of
interesting
chaos.
A
So
submariner
lets
you
connect.
Oh
it'd,
be
really
nice
if
they
had
a
picture
here
it
lets
you
connect
multiple
kubernetes
clusters
together
without
needing
to
go
through
exit
from
the
cluster
and
then
ingress
through,
like
an
ingress
or
a
gateway
somewhere
else,
and
they
can
kind
of
pipe.
You
know
pipeline
stuff
through
that
channel.
A
I
was
just
going
to
put
everything
under
the
video
playlist
heading
or
take
it
out
and
let's
see
the
last
one
was
wasm
edge,
which
is
not
the
sort
of
thing
that's
going
to
make
for
a
flashy
demo,
but
is
a
webassembly
virtual
machine
so
that
you
can
easily
use
webassembly
in
a
bunch
of
different
environments,
and
so
yeah
they've
got
how
to
run
it,
but
they
don't
show
you
how
to
run
doom
on
it.
So
I
can't
really
show
you
anything
exciting.
A
A
A
They
did
sort
of
here's
how
to
do
the
same
response
engine.
So
when
you
see
certain
unexpected
system
calls,
you
can
react
to
it
and,
for
example,
shut
down
the
pod
and
they
did
a
series
of
blog
posts
with
in
conjunction
with
different
projects.
So
three
serverless
platforms
and
then
techton
as
well.
A
B
A
B
A
Let's
see
unless
anyone
else
has
billing
every
time
your
pots
on
a
scale.
Yeah
looks
like
there's
nothing
else
on
these.
You
know
in
the
comments
so
we're
gonna
start
looking
at
pixie,
lab
or
pixie,
which
it
looks
like
the
commercial
version
is
branded
this
way,
and
then
they
have
an
open
source
version.
A
That
looks
basically
the
same,
but
this
one
is
technically
the
new
relics,
the
new
relic
one,
and
this
is
where
pixie
labs
is
gonna,
be
so,
let's
see
so
they
have
just
do
this
and
it'll
all
work.
I
think
well,
there's
a
there's
a
note
that
there's
a
self-hosted
install
script
coming
soon.
So
now,
let's
someone
was
asking
why
a
new
monitoring
project?
A
So
inside
your
cluster,
you
have
these
edge
modules
on
each
node,
lots
of
different
systems,
sort
of
have
that,
but
they
hook
in
with
ebpf
so
that
they
can
get
kernel
level
syscalls,
and
then
they
do
a
kubernetes
native
collection
or
kubernetes
native
system.
With
this
vizier
agent
that
collects
all
the
data
from
the
different
pixy
edge
nodes,
and
then
they
have
an
option
to
send
things
to
their
cloud
or
do
a
direct
connection
called
a
called
a
called
data,
isolation
mode.
And
so
you
can.
A
A
A
A
Yeah
and
so
they
claim
low
overhead
and
maybe
the
ability
to
scale
out
and
so
yeah.
This
is
a
no
instrumentation
approach,
where
it's
not
quite
no
instrumentation,
but
it's
very
low
instrumentation.
At
least
you
do
have
to
build
with
symbols.
I
was
seeing
somewhere
or
only
parts
of
it
work,
but
it
will.
A
C
A
A
I
feel
like
damon
sets,
made
agents
a
lot
less
invasive
back
in
the
back
in
2000
we
didn't
when
we
didn't
have
containers
and
you
had
to
install
the
agent.
You
had
to
worry
about
the
library,
the
library
dependencies
of
the
agent,
as
well
as
the
library
dependencies
of
your
actual
application
and
when
they
com
and
when
they
collided,
then
you
were
really
sad
yeah.
If
this.
A
A
A
B
A
A
B
A
A
B
A
A
A
A
A
A
See
yeah
this
is
this
is
windows.
I
have
windows
subsystem
for
linux
and
I'm
using
mini
cube
on
windows.
I
like
I
like
getting
that
experience
of.
What's
it
like,
and
so
this
is
the
first
hurdle.
I'd
probably
feel
if
I
was
a
windows
developer
is
oh
look,
here's
a
bunch
of
bash
stuff
and
I
have
to
interrupt
it
nicely
if
you
haven't
done
it
before
mini
cube.
Has
some
nice
okay,
if
you're
using
you
know
linux,
do
this?
If
you're
using
mac,
do
this
you're
using
windows?
A
B
B
B
B
A
A
B
A
D
B
B
A
A
A
B
A
B
B
A
D
A
B
A
B
B
C
B
A
B
A
B
C
A
A
B
A
B
B
B
B
C
A
C
B
B
B
B
B
D
B
B
D
A
B
C
B
A
A
C
A
A
A
A
A
B
A
A
A
C
A
And
so
I
would
need
to
set
up
forwarding
all
of
that
to
make
it
work,
and
so
it's
nice
that
they
can
proxy
you
through
the
cloud
and
do
sort
of
a
reverse
pattern.
It
looks
like
it's
also
possible
to
set
up
locally,
since
I'm
interested
in
figuring
out
everything
else.
That
was
quick.
I
don't
know
if
you
noticed
that
I
switched
it
back.
A
A
We
can
group
things
by
namespace,
so
we
can
see
that
almost
all
of
our
cpu
load
is
coming
from
px
online
boutique,
but
we
are
spending,
I
guess,
about
20
percent
of
our
cpu
keeping
track
of
all
of
the
work
going
on
by
dread
by
territon
virtual
memory
size.
And
if
you
remember
back
here,
this
stuff
is
actually
getting
proxied
through
the
cloud
to
the
vizier
on
the
cluster.
So
all
this
data
isn't
actually
getting
pushed
up
into
the
cloud.
A
B
A
A
B
A
B
A
A
A
A
B
B
B
A
B
B
A
A
A
A
B
B
A
A
B
B
B
A
B
A
B
B
A
A
B
B
B
A
B
B
B
C
C
A
A
C
D
A
C
B
C
D
C
A
D
C
A
D
B
A
A
B
B
B
A
A
B
A
A
One
thing
that
I
would
suggest
adding
is
the
ability
to
set
the
end
time,
which
is
really
handy.
If
you
do
have
long
term
retained
data
to
be
able
to
say
during
this
outage
link,
we
did
this,
and
people
can
go
in
and
look
at
the
actual
data
and
you
know
go
back
and
see
if
there
would
be
a
better
way
to
detect
the
problem,
and
then
I
like,
I
like
that,
it's
using
you
know
pandas
rather
than
like.
Oh,
we
made
up
yet
another
language
for
you
to.
D
A
A
A
A
What
the
underlying
data
structures
they're
using
are,
it
looks
like
it's
more
likely
to
be
sampled
traces
than
aggregated
metrics,
so
prometheus's
model
of
the
world
is
basically
things
happen
and
you
increment
counters,
and
your
counter,
you
know,
goes
up
over
time
or
maybe
it's
how
much
disk
space
you're
using,
and
so
you
get
a
number
for
that.
And
then
it
does
a
bunch
of
collection
on
numbers
and
let
you
group
them
up
by
labels
and
do
math
with
that.
A
A
Yeah
it
could,
it
could
probably
intercept
the
mutual
tls
for
istio
if
you're
using
istio
istio
can
also
actually
has
instrumentation.
That
can
do
the
same
thing.
They've
added
that
instrumentation
into
envoy
manually,
but
the
clever
thing
that
pixi
is
doing
is
that
they're
actually
they're
actually
automatically
doing
it.
A
They're,
also
using
ebpf
they're,
basically
creating
a
whole
bunch
of
different
trace
points
in
different
parts
of
the
program,
and
so
there's
some
trace
points
that
are
going
through
the
kernel
and
there
may
be
some
trace
points
that
are
in
the
application
itself,
and
you
can,
you
know,
put
a
whole
bunch
of
different
trace
points
in
there
record
those
traces
and
then
see.
Okay.
A
A
Oh
ebpf
can
do
trace
points
in
user
space.
I
didn't
know
that
cool
okay,
so
yeah
they're,
probably
using
ebpf,
for
that
they
are
probably
also
having
to
hook
the
go
thread.
Implementation
because
all
your
go
all
of
your
go
processes
or
your
your
go
functions.
Your
go
routines,
that's
the
word,
I'm
looking
for
all
your
go.
A
B
B
B
A
B
A
B
B
A
C
A
It's
a
thing
it
does
stuff,
I
don't
think
I'm
gonna
get
to
the
bottom
of
it
in
the
next
five
minutes.
So
I
think
this
is
probably
going
to
be
where
I
cap
it
off,
but
yeah
something
to
keep
an
eye
on.
I'm
particularly
looking
forward
to,
and
I'm
probably
going
to
watch
this
issue
here
for
self-hosted
pixie
install
script,
because
I'd
really
like
to
run
this
on
my
own
environment
without
tethering
it
to
a
cloud.
