A question about snmp: sys.uptime

[Ruijun Fan]

Hello,
I an new on Zabbix,
I use snmp to monitor my remote server.
I have a trigger : {EU1-SHIM-PROD1:sysUpTime.nodata(300)}=1 .
which was fired sometimes.
After I received the alert email ,I checked the graph , there was a gap about 5 min on the curve.
some one told me that it means a system reboot, but I checked the event log on the remote server , there is no system reboot for the specific time .

so are there somebody who can answer my quesiont kindly?

Thanks.

Rui

Ruijun,
I don't know if you are still experiencing the problem with the gap in your data, but it is being discussed here:

I just recently started having this issue.All the suggestions in the above link are not helping and I've ruled out all the common ones that are suggest above.
