We released Graylog v1.1.1 to address several defects that were discovered after v1.1.0 went out. Please see below for more details.
Graylog v1.1.1 can be downloaded from here. (“All releases” section)
The 1.1.0 release shipped with a wrongly named MongoDB database collection for alarmcallbacks. This caused the problem that alarmcallbacks disappeared when you upgraded from Graylog 1.0.x.
