Alert! Alert!

'twas the night before holidays, when all through the servers not a pager was stirring...

Hmm lulled into a false sense of security by the appearance of [WLCG Nagios] entitled emails alerting me about proxy expiry on the shared nagios system I foolishly thought all was well. However we wern't getting any 'real' alerts from the system to the individual sites.

Turned out to be a configuration issue in the /etc/nagios/uki-scotgrid-*/contacts.cfg

We had

service_notification_options n
host_notification_options n
meaning no notifications were sent - changed this to

service_notification_options w,u,c,r,f
host_notification_options d,u,r,f,s

which means we get alerted on pretty much every state change - for more details see the manual

on a more annoying note - I left my macbook PSU back in the UK and there's a limited no of apple resellers here :-(
