Package: mon-contrib
Version: 1.0+dfsg-3
Severity: normal
Tags: patch
The attached patch gives options for the minimum number of alerts to be sent
and the
minimum failure duration before a failure on a remote system is considered to
be a
local failure. If you have multiple servers that are all capable of
independently
notifying the sysadmin then remote.monitor is good to make sure that they are
all
operating correctly. In the normal case the remote server notifies you and if
that
doesn't work then the master server notifies you some time later.
