The correct OID for system uptime
I use SNMP to track system uptime so I know when my hosts have recently rebooted, but I keep making a mistake when picking which OID to monitor and using sysUpTime.0 which is wrong I should be using hrSystem.hrSystemUptime.0.
sysUpTime.0- Timeticks (0.01s) since the snmpd started.
hrSystem.hrSystemUptime.0- Timeticks since the hardware started.
