Today all of my Linux servers were reported offline by Pulseway. I checked and the agents were all crashed. When I tried to restart I get the following from syslog:
Dec 23 19:27:24 email pulseway: Configuration read successfully!
Dec 23 19:27:26 email pulseway: Cannot open /var/log/wtmp

They are all running Ubuntu 12.04.
