It would be useful to have a annotation (note) for both events and actions, that you could add info to, from the ui or from external tools, so in the annotation for actions it could say paged userxx at with a timestamp then ran remote command, make these act as an audit trail for an event that can not be modified unlike the notes for triggers.

01/01/2007 23:00 pagged userxxx
zabbix
01/01/2007 23:10 remote command executed /home/xxx/cleanup
zabbix
01/01/2007 23:30 I see the remote command did not clean up enough space, i am removing more old logs...
