BBNET customize short interval ping



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 protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

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.
