[hobbit] BBNET customize short interval ping

You would be better off writing your own test than to try to do this with the standard Xymon functions. All you need to do is write a test that will ping at one second intervals and record the results. then, at the end of your test you can scan the results and send a consolidated message to Xymon for display.

One ping per second is very aggressive, and you are going to find that many pings are dropped or delayed (deferred) due to normal network activity -- and that this is not a problem.

Hello guys,

I have un other little xymon just for monitore a link throught

VPN, or internet...:)

I'd like to configure xymon to monitor quickly link (every one

second, and less, if possible).

Currentl, my hobbitlaunch is configured as fallow : 


[bbnet]
        ENVFILE /home/xymon/xymon/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD bbtest-net --report --ping --checkresponse
        LOGFILE $BBSERVERLOGS/bb-network.log
        INTERVAL 1s


BUT the time isnt respect: 

root at my_little_xymon:~# tcpdump -i eth0 host 10.X.X.X
tcpdump: verbose output suppressed, use -v or -vv for full

I need to debug issue to micro line cut, and the ping is spaced

out more 1 second.

How to, can I win a time more short than currently, for test

more accurate ?

Thank you.
