updating the nagios configuration files
uploading the new code for hosts management on the Mconf network
some refactor on the folders and a new shell script to backup and deploy configurations on nagios
some new configurations related to the new nagiosgraph code
bug fixing, generating the rrd graphs now
fixed the log of the add-server command; the clean function on mconf-hosts.py, when removes a host because it's a duplicated one, creates a new attribute on the new host called _duplicates that record the items removed because of it
added an artificial host to avoid the startup problem on nagios
uploading the check command for sip
implemented a script to backup the hosts definition once a day
added the port of the Mconf-Live service to the host definition so it's easier to use the port without parse everytime the url; created a new hostgroup for load balancers; fixed the problem on check_sip related to the nagios/libexec path
check-notes-server is still not working fine, need to check; disabling temporarily the ssh check for all hosts
fixed the live notes server service, and also updated the services to the new version of mconf-live
setting up a first notification delay to avoid a huge number of messages; also setting a timeout for the ssh service
Merge branch 'master' of git://github.com/mconf/nagios-etc
renaming the service from "BigBlueButton Version" to "Mconf-Live Version"
added a new passive service to receive the chef run status
