I'm monitoring a set of routers on an IXP LAN and want to know when RTT and
packet loss goes up or when actually a router drops out. Here is how the
config looks like

# Begin snippet

*** Alerts ***

from = xxxx
to = yyyy

+ lossdetect
type = loss
pattern = ==0%,==0%,==0%,>2%,>2%,>2%
comment = dropping more than 2% packets

+ noloss
type = loss
pattern = >2%,>2%,>2%,==0%,==0%,==0%
comment = packet loss back to normal

+ rtthigh
type = rtt
pattern = <2,<2,<2,>4,>4,>4
comment = RTT more than 4ms

+ rttnormal
type = rtt
pattern = >4,>4,>4,<2,<2,<2
comment = rtt normal again

+ unreachable
type = rtt
pattern = !=U,!=U,!=U,==U,==U,==U
comment = unreachable

+ reachable
type = rtt
pattern = ==U,==U,==U,!=U,!=U,!=U
comment = reachable again

....

+ XXXXXX

menu = XXXXX
title = blafasel blubb
alerts = unreachable,reachable,rtthigh,lossdetect,noloss,rttnormal


# End Example snippet

This automically sets the alert for all level levels below. Of course you
may override these settings on each level.
