Adding new cycle for nagios notifications

Nagios has a file that lists time periods that notifications will be emailed in, many are "all the time" but some are set to be within cycle only, particularly ones that notify scientists e.g. muon pulse width or kicker check. The service will always go red in nagios web display, but not send an email alert unless the current time is within the linked timeperiod. So this file needs to be updated with new isis cycle dates as appropriate. To do this:

• log onto control-mon.isis.cclrc.ac.uk linux machine
• cd /usr/local/nagios/etc/objects
• edit timeperiods.cfg with your favourite linux editor. At the bottom of the file there is a timeperiod called isis_cycle and add a new line to this in the same format as the rest of the define. We use friday before start of user run for our start time - the web page https://www.isis.stfc.ac.uk/Pages/Beam-Status.aspx lists start of user run which is the tuesday, so count back 4 days from that
• run sudo service nagios reload to load changes
