[hobbit] Sending Hobbit data from one server to another

Fri Mar 7 09:32:33 CET 2008

Hi,

In the past I struggled the same. Here is a summary what I did to make it work:

Situation:

Before:

- Local hobbit listens on 10.15.xxx.xxx port 1984 
- Local clients sends messages to IP 10.15.xxx.xxx port 1984 

With bbproxy:

- Local hobbit listens on 127.0.0.1 port 1984 
- Local bbproxy listens on 10.15.xxx.xxx port 1984 
- Local clients sends messages to IP 10.15.xxx.xxx port 1984 (bbproxy) 
- bbproxy forwards incoming messages to 127.0.0.1 port 1984 AND to remote hobbit (10.170.xxx.xxx) port 1984 

This is what needs to be changed on the local hobbit sever:

- Add a --listen=127.0.0.1 to hobbitd in hobbitlaunch.cfg on local hobbit 

- Enable bbproxy on local hobbit in hobbitlaunch.cfg. Use the option "--bbdisplay=127.0.0.1,10.170.xxx.xxx" to tell bbproxy to forward to both server and add --listen 10.15.xxx.xxx so it will listen on this IP for incoming messages 

- Change the BBSERVERIP setting in hobbitserver.cfg to point at the 127.0.0.1 address. 
This setting is used e.g. by the web CGI's that talk to the "real" hobbit server, so it is best to point this at the real server IP, not the proxy. 

- Because there are also running network tests from the same server, we need to change the CMD setting of [bbnet]  in hobbitlaunch.cfg also.
Instead of calling bbtest-net directly, put it into a shell script wrapper and set BBDISPLAY explicitly to 10.15.xxx.xxx. Otherwise it will pick up the BBSERVERIP setting (127.0.0.1) and send the network test results to 127.0.0.1 - so they won't go through the proxy, and hence you won't see them on the remote server. 

- Restart Hobbit 

>From the hobbitlaunch.cfg on the local hobbit server:

[hobbitd]
        HEARTBEAT
        ENVFILE /opt/hobbit/server/etc/hobbitserver.cfg
        CMD hobbitd --pidfile=$BBSERVERLOGS/hobbitd.pid --restart=$BBTMP/hobbitd.chk --checkpoint-file=$BBTMP/hobbitd.chk 
        --checkpoint-interval=600 --log=$BBSERVERLOGS/hobbitd.log --admin-senders=127.0.0.1 --store-clientlogs=!msgs --listen=127.0.0.1

[bbproxy]
        ENVFILE /opt/hobbit/server/etc/hobbitserver.cfg
        CMD $BBHOME/bin/bbproxy --hobbitd --display=127.0.0.1,10.170.xxx.xxx     
  --report=$MACHINE.bbproxy --pidfile=$BBSERVERLOGS/bbproxy.pid 
  --listen=10.15.xxx.xxx --no-daemon
        LOGFILE $BBSERVERLOGS/bbproxy.log

[bbnet]
        ENVFILE /opt/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD $BBHOME/bin/net-test.sh
        LOGFILE $BBSERVERLOGS/bb-network.log
        INTERVAL 5m

Wrapper script for bbtest-net:

#cat $BBHOME/bin/net-test.sh

#!/bin/sh
export BBDISP=10.15.xxx.xxx
$BBHOME/bin/bbtest-net --report --ping -checkresponse

All that done  it's working!

Hope this helps...
