Data Collection Best Practices Counter Discontinuity
- Counters should not be reset without a way to determine the reset
- Leads to inaccurate delta calculations
- Two ways to determine a counter reset:
- Polling sysUpTime for reset
- Reset every time SNMP agent is reset
- Note: sysUpTime wraps every 1.36 years
- Poll the discontinuity timer if it exists
- Look in the description of the counter in the MIB module
