riemann-dash does not allow setting host as documented. #11

blt · 2013-03-03T03:07:11Z

The riemann-dash documentation implies that setting config[:client][:host] will target a non-default riemann server. When this setting is left at its default I find:

riemann@riemann:~$ cat dash.config 
set :bind, "REDACTED_IP"
#config[:client][:host] = 'REDACTED_IP'

riemann@riemann:~$ riemann-dash dash.config 
== Sinatra/1.3.5 has taken the stage on 4567 for development with backup from Thin
>> Thin web server (v1.5.0 codename Knife)
>> Maximum connections set to 1024
>> Listening on REDACTED_IP:4567, CTRL+C to stop
^C>> Stopping ...

however

riemann@riemann:~$ cat dash.config 
set :bind, "REDACTED_IP"
config[:client][:host] = 'REDACTED_IP'
riemann@riemann:~$ riemann-dash dash.config

Good catch! This is a total lie; artifact of outdated documentation. Pretty much all configuration, including the Riemann server, happens in the browser now. My apologies!

blt · 2013-03-03T18:12:50Z

Oh, okay! How do I configure riemann-dash to hit a non-localhost riemann server, then? I have a riemann-dash running at http://riemann.troutwine.us:4567/ and a server at the same host on the default port. When I enter riemann.troutwine.us:5555 in riemann-dash's top right-hand box, nothing changes.

Is there any way to make riemann-dash default to a non-localhost server?

@blt I have the same config as you and it's working, but the default port for the websockets is 5556

@aphyr there's another bit of info that may be useful to have on the README:

set :bind, 'localhost' # Default 0.0.0.0

I needed to secure my installation behind a reverse proxy and it took me a while to find out that it was Sinatra's configuration :)

blt · 2013-03-05T17:43:42Z

@default50 Hmm, even after correcting the port, nothing. My riemann-dash is running http://riemann.troutwine.us:4567/ and when I boot riemann server I find:

iemann@riemann:~/riemann-0.1.5$ ./bin/riemann etc/riemann.config

which seems good. nmapping the server:

blt> nmap riemann.troutwine.us

Starting Nmap 6.25 ( http://nmap.org ) at 2013-03-05 09:38 PST

Nmap done: 1 IP address (1 host up) scanned in 3.98 seconds

so 5556 doesn't look open. There's no firewall or anything on this box: it's a vanilla Debian Wheezy install. Anyway, when I enter riemann.troutwine.us:5556 into the dash's server box and hit enter nothing happens, no error and no change.

Am I misunderstanding something here? My riemann server config:

; vim: filetype=clojure
(logging/init :file "riemann.log")

; Listen on the local interface over TCP (5555), UDP (5555), and websockets; (5556)
(let [host "166.78.122.49"]
  (tcp-server :host host)
  (udp-server :host host)
  (ws-server  :host host))

; Expire old events from the index every 5 seconds.
(periodically-expire 5)

; Keep events in the index for 5 minutes by default.
(let [index (default :ttl 300 (update-index (index)))]

  ; Inbound events will be passed to these streams:

    ; Index all events immediately.
    index

    ; Calculate an overall rate of events.
    (with {:metric 1 :host nil :state "ok" :service "events/sec"}
      (rate 5 index))

    ; Log expired events.
    (expired
      (fn [event] (info "expired" event)))
))

and the dash config:

set :bind, "166.78.122.49"

An interesting discovery from last week: the :host option to Aleph
(which powers the websocket server) doesn't actually do anything. I
think it should bind to 0.0.0.0 no matter what :host you pass... but I
wonder if it's doing some weird IPv6 thing instead. You might try
netstat -nl to see if it bound correctly.

That's not localhost, it's 0.0.0.0 equivalent of IPv6 @blt.

BTW, I'm running on vanilla Wheezy too, on EC2. Of course I have opened up port 5556 on the firewall.

This is my netstat output:

@default50 Quite so; I'm less familiar with IPv6 than I should be.

I still don't see 5556 as open, via nmap. I continue to be unable to attach the dashboard to the server on riemann.troutwine.us. (I am correct in believing that I need only add the server name/port into the box at the top right-hand corner and hit enter?)

If nmap reports the port is closed, you're probably looking at a
firewall. Might be anywhere in between your browser and the server.

@blt you only need that.

nmap doesn't scan all 64k ports by defaul. Your port looks open, even from here:

nmap -p 5555,5556 riemann.troutwine.us

Starting Nmap 6.00 ( http://nmap.org ) at 2013-03-05 15:17 ART

I could even telnet into it! ;)

Escape character is '^]'.

telnet> Connection closed.

Moreover, and sorry if I'm tripping on you, but I loaded your dash on my browser (port 4567) and changed the URL to riemann.troutwine.us:5556 which stopped the message about lost connections. Changed the grid query to true and saw everything empty, but didn't got an error either (maybe you aren't pushing any data into riemann yet?)

I suspect your client is misbehaving, or maybe you (as a client) are behind some outgoing firewall?

blt · 2013-03-05T18:31:17Z

Hmm... On the box itself:

root@riemann:~# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

@default50's input suggests I'm misusing nmap.

@default50 I can see from the logs someone from 190.176.144.135 connecting to the server. Please, be my guest, if that is you. This is a scrub box entirely.

It's possible that I don't understand how to make use of the dashboard, is all. Is there a video tutorial on its use?

No, but I'll link to one if you make it! You should just have to type
riemann.troutwine.us:5556 in the box at the top right and hit enter; if
that doesn't work, I'd suspect a firewall still.

@blt that's my IP :) Hi!

Just configured your dash and saved the config, and your described usage is as it's meant to be.

Some tests that could be useful:

Try with a different (newer) browser (or even computer) [It's worked for me on Firefox and Chromium under Linux]
Try under a different ISP

I'm pretty sure it's the client's problem only (browser).

blt · 2013-03-05T19:08:55Z

Hi, @default50!

I think simply it's that I don't understand how to use the dashboard. How did you, for instance, configure the dashboard? I undertand how you edited the view to read "This was changed by default50 as a test, sorry!", but not what you did to make a certain server default.

I've used latest Chrome, Safari and Firefox on two separate OS X machines, and Firefox/Chrome on a linux box from a different ISP. Surely my problem is a lack of knowledge about the dashboard's operating.

The views, workspaces, and the server address you type in to the top
left are all stored as JSON on the riemann-dash server. When you save
the config, it saves the currently connected riemann server as well.
