%description
The merlin daemon is a multiplexing event-transport program designed to
link multiple Nagios instances together. It can also inject status
data into a variety of databases, using libdbi.


%package -n monitor-merlin
Summary: A Nagios module designed to communicate with the Merlin daemon
Group: op5/Monitor
Requires: op5-nagios >= 3.99.99.4, merlin = %version-%release
Requires: monitor-config

%description -n monitor-merlin
monitor-merlin is an event broker module running inside Nagios. Its
only purpose in life is to send events from the Nagios core to the
merlin daemon, which then takes appropriate action.


%package apps
Summary: Applications used to set up and aid a merlin/ninja installation
Group: op5/Monitor
Requires: libdbi, rsync, MySQL-python
Obsoletes: monitor-distributed

%description apps
This package contains standalone applications required by Ninja and
Merlin in order to make them both fully support everything that a
fully fledged op5 Monitor install is supposed to handle.
'mon' works as a single entry point wrapper and general purpose helper
tool for those applications and a wide variety of other different
tasks, such as showing monitor's configuration files, calculating
sha1 checksums and the latest changed such file, as well as
preparing object configuration for pollers, helping with ssh key
management and allround tasks regarding administering a distributed
network monitoring setup.
