I'd like to know how Orion determines a reboot. I see that we can alert off the "LastBoot". We have an uptime report and want to compare that to the "LastBoot" variable in Orion.
Thanks.
The Uptime is based on the SysUptime OID 1.3.6.1.2.1.1.3.
Thank you.
I guess I am getting conflicting information.
From OrionDB i do a
Select Caption,SystemUptime from Nodes Where Caption=servername
31690.12 -- is the result
However when I log in the server and look at the eventlog the Uptime value is off such as
"The system uptime is 5623659 seconds."
That is way off.
Hi
I have seen this in the past
sysUptime 1.3.6.1.2.1.1.3 = Is the time the management agent has been up not the server. Its always been a misleading measurement when it comes to servers. So if someone has restarted the SNMP agent then most NMS systems will think it rebooted.
What NMS systems should be monitoring if possible is the Host resources SNMP sysuptime if available as that measures the actual server uptime, which is the same value you are seeing on your server event log. Not all SNMP agents support this MIB, but there are some out there that do.
That will explain the difference.
Hope that helps
James
