[Discuss] Monitoring your AWS instances

[Edward Ned Harvey (blu)]

None of our systems are scheduled for reboot, *and* the machines triggering our alerts have not been rebooting - they just become unavailable on the network for a few minutes and then reappear, without any sort of crash or reboot or anything affecting "uptime."  *And* this has been a general issue progressively getting worse and worse over the last several months (but especially bad lately.)

For the sake of discussion here, I just pulled reports on the numbers of alerts isolated to Amazon:
