[Xymon] bbproxy max server

[Henrik Størner]

Hi,

> 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 ?

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.
