Counter wraps. Nothing we can do about that.

Hi Stefano,

late last year I observed the same phantom reboot symptoms when

monitoring

a number of NetGear gigabit switches (I know that NetGear is not the

best

kit to use with Observium). The strange thing is that none of the

devices

had rebooted and they all reported long up-times when queried directly.

Here is a summary of the phantom reboot events:

After the alerts arrived, I contacted the data centre and it was

confirmed

that there had been no loss of power or planned works that could have affected the network. There were no more false reboot events up until I stopped using Observium (pending the implementation of formal support

for

alerting).

Best regards

Darren

Hello List, I'm testing observium to monitor network devices in our datacenter,

I've

Where does observium takes the info about reboot?

Observium is installed in a VM: Observium 0.13.3.3824 Apache 2.2.22 (Ubuntu) PHP 5.3.10-1ubuntu3.6 MySQL 5.5.29-0ubuntu0.12.04.2 RRDtool 1.4.7
