bbproxy max server 🔗 link

hello Henrik

what do you think about increasing the value of MAX_SERVERS from 3 to 5 in bbproxy.c ? What kind of impact can we expect ? If you don't recommend to increase this can we run chained bbproxy ?

Another point about bbproxy. You recommend to do this config :
[bbproxy]
       ENVFILE /opt/hobbit/server/etc/hobbitserver-proxy.cfg
       CMD $BBHOME/bin/bbproxy --hobbitd --bbdisplay=IP1,IP2,IP3 --report=$MACHINE.bbproxy --no-daemon --pidfile=$BBSERVERLOGS/bbproxy.pid --listen=IP0
       LOGFILE $BBSERVERLOGS/bbproxy.log

and not this one :

[bbproxy]
        ENVFILE /opt/hobbit/server/etc/hobbitserver-proxy.cfg
        CMD $BBHOME/bin/bbproxy --hobbitd --bbdisplay=127.0.0.1:1985,127.0.0.1:1986,127.0.0.1  --report=$MACHINE.bbproxy --no-daemon --pidfile=$BBSERVERLOGS/bbproxy.pid --listen=IP0:1984
        LOGFILE $BBSERVERLOGS/bbproxy.log

[bbproxyFORWARDER]
        ENVFILE /opt/hobbit/server/etc/hobbitserver-proxy.cfg
        CMD $BBHOME/bin/bbproxy --hobbitd --bbdisplay=IP1   --no-daemon --pidfile=$BBSERVERLOGS/bbproxyFORWARDER.pid --listen=127.0.0.1:1985
        LOGFILE $BBSERVERLOGS/bbproxyFORWARDER.log

[bbproxyDEV]
        ENVFILE /opt/hobbit/server/etc/hobbitserver-proxy.cfg
        CMD $BBHOME/bin/bbproxy --hobbitd --bbdisplay=IP2   --no-daemon --pidfile=$BBSERVERLOGS/bbproxyINOFYS.pid --listen=127.0.0.1:1986
        LOGFILE $BBSERVERLOGS/bbproxyINFOSYS.log


but in the first config when one server is not responding the message are delayed a long time and we got purples. 
So I put the second one in production.

oau

Hi,

I don't think the "3" is some sort of magical number, so the code wouldn't need any major changes to accomodate a larger number of destination.

However, you have to consider the time it takes to send data to so many destinations: Xymonproxy needs to connect to each one of these and transmit the data, so if you have a large installation (and I guess you do, if you need to distribute the data to so many Xymon servers) then that may become an issue and you'll start to see the queue-time in xymonproxy rising, and perhaps clients starting to drop data because they cannot connect to the proxy.

You have different "listen" adresses for the three proxies. Then you do need to run them as three separate instances.
