Ah! Thanks Mike, I will be turning that option off for the time being then I think :)

Yeah I did that search, the event log search contains no events for the device that considers itself to have rebooted on the front page, it does contain events for devices that rebooted previously, If I search specifically against the device, the search is empty.

Ahh, that enent :D It really is not related to fixed in previous commits..
Here just check if uptime less than in config option: $config['uptime_warning'] = "86400"; // Time in seconds to display a "Device Rebooted" Alert. 0 to disable warnings.
I will try to fix this issue, that option a long time not actual :)
I'll send the debug output over shortly off list.

Actually, now you mention it, this is actually only showing on the front page 'device alerts' under the map, it didn't actually trigger an event in the event log that I can see? (and there is no alert mail setup as yet)
Additionally include debug output for this device from system poller: ./poller.php -d -m system -h <your_device>
In eventlogs, go to http://your_observium/eventlog and use search, like:

Hi Michael,
We are running r6531 and I’ve just had a device flag as rebooted after the counter rolled over at 497 days, are we sure this improvement is working as intended?
you are sure that device not really rebooted? ;)
Well, show me eventlog message (and if exist alert mail with this reboot condition).
Thanks,
Tim C

Did the math, and this makes since. Thank you. The math checks out that this device will rollover in uptime every 497 days.
Rollover reboot issue after 497 days now should be fixed since r6419.

Okay, but sysUptime is not recorded in seconds but 1/100ths of a second. Also, 32bit signed integer is only good for 135 years with one second resolution (as time doesn’t start from negative numbers, it’s only really 2^31 available space)

It says it is an eight-byte signed integer. That’s 2^63 correct? There should be several millennia before a rollover if my interpretation is correct.

This is a standard issue with 32 bit counters and uptimes, so I’d start with google first! J
This isn’t an observium/database issue.

Right, the graph shows an uptime of ~ 8 hours now, but the device itself says 497 days. Which observium concurs with… until about 8 hours ago.
I’m not great with sql so am getting a co-worker to pull the DB info to see if that sheds any more light on the issue.

Device-->Graphs-->System tab. One of the graphs will show you uptime.

Right, I checked my config.php and saw it as a 24hour setting.
I’ll look in the database for any uptime count.

A device uptime of < 24 hours by default.
My guess is the SNMP counter rolled over on whatever device it's monitoring so observium sees it as a reboot.
