Bokeh Server Question

azaringhalam · January 14, 2016, 3:29am

I am new to bokeh (< 1 day) but quite impressed. It looks like what I am looking for: to publish a time series from Redis and display it on a browser using bokeh server.

Before trying a time-series I tried to go through the tutorial by trying to run the server on an interface other than localhost:

  bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006 /home/aliz/mybokeh/ /home/aliz/mybokeh/apps/*

Now if I put say sliders.py (from the git) in apps, I can access it from the browser on another host at 10.10.10.200 on the same subnet. Great!

But what I have not been able to do is to post a graph to the bokeh server and access it from a browser on 10.10.10.200. I tried to run the following example from the tutorial:

#!/usr/bin/python
from bokeh.plotting import figure, output_server, show
x = [1, 2, 3, 4, 5]
y = [6, 7, 2, 4, 5]
output_server(session_id=‘None’, url=‘http://10.10.4.252:5006’, app_path=’/home/aliz/mybokeh/app/’, autopush=False)
p = figure(title=“simple line example”, x_axis_label=‘x’, y_axis_label=‘y’)
p.line(x, y, legend=“Temp.”, line_width=2)
show(p)

But I get:

INFO:bokeh.client.connection:Failed to connect to server: HTTPError(404, ‘Not Found’, HTTPResponse(_body=None,buffer=<_io.BytesIO object at 0x7f71358bcbf0>,code=404,effective_url=‘http://10.10.4.252:5006/home/aliz/mybokeh/app/ws?bokeh-protocol-version=1.0&bokeh-session-id=None’,error=HTTPError(…),headers=<tornado.httputil.HTTPHeaders object at 0x7f7135869f90>,reason=‘Not Found’,request=<tornado.httpclient.HTTPRequest object at 0x7f7135869c10>,request_time=0.004470109939575195,time_info={}))
Traceback (most recent call last):

IOError: Cannot push session document because we failed to connect to the server (to start the server, try the ‘bokeh serve’ command)

I think the problem is with show(p) which seems to work only if you are accessing the plot on a browser on localhost. But I have not been able to figure out what API to use.

Suggestions about this problem as well on plotting time-series published by Redis are greatly appreciated.

Hi,

app_path should be the path in the URL (just /foo if the script is called foo.py) rather than the filesystem path. Don’t know if that’s the only issue but it may be the immediate cause of the error you got.

Havoc,

is app_path needed/relevant when trying to push a new plot to a server using output_server?

To start, I think maybe you want

session_id = None # actual python None type

not

session_id = "None" # not a string with the value "None"

If you do “bokeh serve” with no args then it isn’t since the default path of / will be right, but if the server has a script you would need a path matching the script. Of course, it doesn’t make sense in most cases to have a script on the server side and also output_server since the output_server will overwrite what the script does. So that may be an issue.

I was looking at

bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006 /home/aliz/mybokeh/ /home/aliz/mybokeh/apps/*

Thank you for your comments & suggestions.
I tried ‘None’ => None but I got a syntax error. I also played around with other suggestions about app_path but continue to have the same problem.
I looked at this server example on the git: https://github.com/bokeh/bokeh/blob/master/examples/plotting/server/animated.py
and tried to run it with a few trial modifications. Several trails are shown below. In all cases I get the following error:
IOError: Cannot push session document because we failed to connect to the server (to start the server, try the ‘bokeh serve’ command)
netstat confirms server is running (tcp 0 0 10.10.4.252:5006 0.0.0.0:* LISTEN 12003/python) and I can access scripts using a browser on another host.
**So the basic problem is this: how do you push/publish a graph on the bokeh server and have it accessible from another host’s browser on the same subnet? All examples and tutorials I have seen use localhost assuming the browser is running on the same host as the bokeh server. **

====================================================================animated.py====================
bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006 $HOME/mybokeh

#!/usr/bin/python

I am new to bokeh (< 1 day) but quite impressed. It looks like what I am looking for: to publish a time series from Redis and display it on a browser using bokeh server.

Before trying a time-series I tried to go through the tutorial by trying to run the server on an interface other than localhost:
  bokeh serve --address 10.10.4.252 --host [10.10.4.252:5006](http://10.10.4.252:5006) /home/aliz/mybokeh/ /home/aliz/mybokeh/apps/*
Now if I put say sliders.py (from the git) in apps, I can access it from the browser on another host at 10.10.10.200 on the same subnet. Great!

But what I have not been able to do is to post a graph to the bokeh server and access it from a browser on 10.10.10.200. I tried to run the following example from the tutorial:

#!/usr/bin/python

But I get:

I think the problem is with show(p) which seems to work only if you are accessing the plot on a browser on localhost. But I have not been able to figure out what API to use.

Suggestions about this problem as well on plotting time-series published by Redis are greatly appreciated.

You would want to provide the URL to push_session rather than to show() I think.

I guess the exception you get is probably from push_session?

I tried ‘None’ => None but I got a syntax error. I also played around with other suggestions about app_path but continue to have the same problem.
I looked at this server example on the git: https://github.com/bokeh/bokeh/blob/master/examples/plotting/server/animated.py
and tried to run it with a few trial modifications. Several trails are shown below. In all cases I get the following error:
IOError: Cannot push session document because we failed to connect to the server (to start the server, try the ‘bokeh serve’ command)
netstat confirms server is running (tcp 0 0 10.10.4.252:5006 0.0.0.0:* LISTEN 12003/python) and I can access scripts using a browser on another host.
**So the basic problem is this: how do you push/publish a graph on the bokeh server and have it accessible from another host’s browser on the same subnet? All examples and tutorials I have seen use localhost assuming the browser is running on the same host as the bokeh server. **

I changed:

But got the same error:

IOError: Cannot push session document because we failed to connect to the server (to start the server, try the ‘bokeh serve’ command)

Now, I also this from the server’s debug trace (putting the urk in show() or leaving it out makes no difference in this):

It looks like it is using websocket instead of http although that doesn’t explain much.

Havoc_Pennington · January 14, 2016, 7:56pm

Are you running bokeh serve with a script or bare with only the --address / --host options?

What happens if you connect to http://10.10.4.252:5006 with a browser or wget or curl?

The 404 on /ws implies that you may be running the server with a script instead of bare. If so you need an app_path=“/foo” so if your script is foo.py you get /foo/ws instead of /ws

But running with a script and then also doing push_session usually doesn’t make sense. You typically generate the document either on client or server not both. If you are generating on client don’t pass a script to bokeh serve.

But what I have not been able to do is to post a graph to the bokeh server and access it from a browser on 10.10.10.200. I tried to run the following example from the tutorial:

p = figure(title=“simple line example”, x_axis_label=‘x’, y_axis_label=‘y’)
p.line(x, y, legend=“Temp.”, line_width=2)
show(p)

But I get:

I think the problem is with show(p) which seems to work only if you are accessing the plot on a browser on localhost. But I have not been able to figure out what API to use.

Suggestions about this problem as well on plotting time-series published by Redis are greatly appreciated.

Havoc,

I think the desire is to be able to "publish" a new document to already running server (that may also happen to be running an other, different app or apps).

I can believe that might currently require one Bokeh server to run the apps, and a second, plain "bokeh serve" for the "publish" part, but I'm not sure about the subnet issue yet. I suppose that might be a current bug or limitation.

Are you running bokeh serve with a script or bare with only the --address / --host options?

What happens if you connect to http://10.10.4.252:5006 with a browser or wget or curl?

The 404 on /ws implies that you may be running the server with a script instead of bare. If so you need an app_path="/foo" so if your script is foo.py you get /foo/ws instead of /ws

But running with a script and then also doing push_session usually doesn't make sense. You typically generate the document either on client or server not both. If you are generating on client don't pass a script to bokeh serve.

It looks like it is using websocket instead of http although that doesn't explain much.

Thanks Havoc. Yes I was running bokeh serve with an app path. This was just to see that I can browse graphs from another box. I took it out and it made a difference for the server but it is still not quite there. Here’s a summary:

Run “bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006 --allow-websocket-origin 10.10.4.252:5006 $HOME/mybokeh”. Now if I try to post a graph to the server it fails. This is what I had done until now.
Now take out the script path: “bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006”. Running animated.py does not produce IOError (confirming your suggestion). But it looks like it tried to display on the server’s console because I see this: " Viewing . Clearly no graph shows up on the console. So even though “session = push_session(curdoc(), url=‘http://10.10.4.252:5006’)”, it doesn’t output there.

A server with scripts is the same as one without except that without scripts we default to an "empty" script and a path of /

But a client should be able to push and overwrite a script-generated doc right

I think the problem is with show(p) which seems to work only if you are accessing the plot on a browser on localhost. But I have not been able to figure out what API to use.

Suggestions about this problem as well on plotting time-series published by Redis are greatly appreciated.

show() just uses the python stdlib webbrowser module (locally, on whatever machine you run show() on) to open up a constructed URL. It's not possible for the server to try and open a browser, unless show() was executed on the server. Can you confirm the URL that your (local) browser tries to open is the correct one, to the server on the other subnet? Alternatively if you navigate your browser there by hand, instead of using show? Is it possible to share server log output? Can you ever see the connection from the python client, or the doc being updated occur?

Thanks Havoc. Yes I was running bokeh serve with an app path. This was just to see that I can browse graphs from another box. I took it out and it made a difference for the server but it is still not quite there. Here's a summary:

1. Run "bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006 --allow-websocket-origin 10.10.4.252:5006 $HOME/mybokeh". Now if I try to post a graph to the server it fails. This is what I had done until now.
2. Now take out the script path: "bokeh serve --address 10.10.4.252 --host 10.10.4.252:5006". Running animated.py does not produce IOError (confirming your suggestion). But it looks like it tried to display on the server's console because I see this: " Viewing <Bokeh Application>. Clearly no graph shows up on the console. So even though "session = push_session(curdoc(), url='http://10.10.4.252:5006')", it doesn't output there.

I am trying to run the animated.py example from the git with changes to url. Here it is:

==========================animated.py===================
#!/usr/bin/python

You must first run “bokeh serve” to view this example

from numpy import pi, cos, sin, linspace, roll

from bokeh.client import push_session
from bokeh.io import curdoc
from bokeh.plotting import figure

M = 5
N = M10 + 1
r_base = 8
theta = linspace(0, 2pi, N)
r_x = linspace(0, 6*pi, N-1)
rmin = r_base - cos(r_x) - 1
rmax = r_base + sin(r_x) + 1

colors = [“FFFFCC”, “#C7E9B4”, “#7FCDBB”, “#41B6C4”, “#2C7FB8”, “#253494”, “#2C7FB8”, “#41B6C4”, “#7FCDBB”, “#C7E9B4”] * M

figure() function auto-adds the figure to curdoc()

p = figure(x_range=(-11, 11), y_range=(-11, 11))
r = p.annular_wedge(0, 0, rmin, rmax, theta[:-1], theta[1:],
fill_color=colors, line_color=“white”)

open a session to keep our local document in sync with server

#session = push_session(curdoc())
session = push_session(curdoc(), url=‘http://10.10.4.252:5006’)

ds = r.data_source

def update():
rmin = roll(ds.data[“inner_radius”], 1)
rmax = roll(ds.data[“outer_radius”], -1)
ds.data.update(inner_radius=rmin, outer_radius=rmax)

curdoc().add_periodic_callback(update, 30)

session.show() # open the document in a browser
#session.show(url=‘10.10.4.252:5006’, app_path=‘/home/aliz/mybokeh/apps’) # open the document in a browser
#session.show(url=‘http://10.10.4.252:5006’) # open the document in a browser

session.loop_until_closed() # run forever

Makes sense. Here’s my setup:

A single subnet with two hosts. bokeh server on 10.10.4.252 and my laptop running browser on 10.10.10.204. So RE: “to the server on the other subnet?”, there is no other subnet, just one.
My browser tries to open 10.10.4.252:5006.
If I run bokeh serve with a script in the app_path, it works fine.
Here is the debug trace from the server when it starts and after I open http://10.10.4.252:5006 from my laptop browser at 10.10.10.204:
